"Alecia's Kid" Summoner, Spirit Summoner; Human

Self-Interested Preface: This post's a little different- my best friend was gonna play in a campaign with me and some other people and had a really cute premise for her character (her character's a kid and its older brother dies and in a grief blackout it learns to summon either him or something so vivid it might as well be him) but she's not very experienced with Pathfinder, so I asked if I could help put her character together.  I'm kind of shitty at moderation when it comes to builds, though, so I just sat down and created a badass- this is a thematic summoner with a huge amount of options who doesn't necessarily replace any roles but absolutely supplements all of them.

Instead of doing a write-up here in the preface, I'll just copy-paste what I already did for her to help her understand the game and her character's abilities to be able to make informed decisions of action.  I taper it off as it progresses with the understanding that she'll need less words over time to comprehend the character's function, but you should still go ahead and get prepped for a ton of fucking words!  readysetgo

This build created in January of 2017.

Summoner (Spirit Summoner) Level 20

Race: Human, +2 CHA (+1 Hit Point/+1 Skill Point/+1 Hit Point or Skill Point to eidolon)

Racial Traits

Dimdweller (+2 Intimidate, Perception, and Stealth when concealed by areas of dim or lower light)

Focused Study (bonus Skill Focus feat at 1st, 8th, and 16th level)

Darkvision 60’

Human’s the race for this build because of the floating attribute bonus and free Skill Focus feats, one of which (Stealth) is needed for the variant Hide In Plain Sight feats this character gets at levels 7 and 11.  Dimdweller’s an extra +2 Stealth in dim or lower light and darkvision, which is exceptionally useful.

Character Traits/Drawbacks

Drawback: (Detriment, Circumstance)

Faith: Loyalty Across Lifetimes (eidolon’s CON counts as 2 higher when determining banishment; +1 to eidolon’s saving throws against enchantment effects)

Magic: Magical Lineage: Haste (Metamagic applied to Haste adjusts its final spell level by -1.)

Regional: Highlander [+1 Stealth (+2 in hilly/rocky areas), Stealth is always class skill]

Magical Lineage lets Haste be cast Extended at its level forever, meaning double-duration Haste for free.  Highlander’s important to give this character Stealth as a class skill.  Loyalty Across Lifetimes is a hella-thematic Summoner-only trait which boosts the eidolon a little.

Stat spread’s pretty good for min-maxing.  CON and DEX can be switched, but DEX affects AC, ranged attacks, Reflex, and Stealth, where CON only affects Fortitude saves and Hit Points.  INT’s 12 to add a little skill versatility, but could be 10 to boost STR slightly or add a Will bonus.

Class Skills: Craft (Any), Diplomacy, Fly, Handle Animal, Knowledge (Any), Linguistics, Profession (Any), Ride, Spellcraft, Stealth, Swim, and Use Magic Device.

Known Languages: Common

1: Summoner (Spirit Summoner) 1 (d8 Hit Die), +1 Hit Point

            BAB: +0

            Base Saves: +2/+3/+2

New Feats: Hero Points, Simple Weapon Proficiency, Light Armor Proficiency, Summoner Spellcasting, (Spirit Summoner) Eidolon, Life Link, Spirit: Ancestors, Ancestor’s Council, [1^st Level Feat] Resilient Eidolon, [Focused Study] Skill Focus: Stealth

Skills(3): Climb/Swim, Stealth, Use Magic Device

New Spells:    0^th Level- Detect Magic, Guidance, Light, Message

1^st Level- Mage Armor, Protection From Evil, (Spirit) Unseen Servant

Base Spells Per Day: 2 Lvl. 1

First level, as standard for a summoner, this character has light armor proficiency, simple weapon proficiency, its eidolon which takes ten minutes to summon, and the Life Link ability which lets it sacrifice its hit points to protect its eidolon from death.  It also stays out for one additional round per level if you die or fall unconscious, which is fucking amazing as long as it’s not rogue from domination or something.  It’s missing the summoner’s Summon Monster class ability which lets it summon creatures as a standard action a certain amount of times per day- this ability doesn’t function while the eidolon’s out (which in your case’d be all the time) and was worth trading out for all the fantastic powers the Spirit Summoner archetype brings in.  The first new power is Ancestor’s Council, the Ancestor spirit ability:

Ancestor’s Council

Action: Standard Action, no AoO

Target: Single ally within 30’ (including self)

Frequency: 3+CHA/day
Function: Add +2 to any ability check, attack roll, saving throw, or skill check made by target before the beginning of your next turn.
(NOTE: This doesn’t say “any one”- it says “any”.  If that’s a flat stacking +2 to all of these things for an entire turn, that’s certainly overpowered but it’s arguable RAW that needs to be clarified.)

Another thing worth noting is that this character’s very capable of scouting- with Stealth as a class skill, a +3 modifier from DEX, a skill point investment, trait bonus, and Skill Focus, Stealth for this character’s currently at a flat +11, +2 in dim or lower light, +1 in hilly or rocky areas.  Spells are pretty standard- the summoner has some neat attack spells but is a better buffer and utility caster.  Unseen Servant’s a really neat spell if you’re creative, and it’s free.

Eidolon Class Skills: Acrobatics, Bluff, Craft (Any), Diplomacy, Intimidate, Knowledge (Planes), Perception, Sense Motive, Stealth, and Use Magic Device.

1: Spirit Summoner’s Ancestral Eidolon (1 HD)

            HP: 5 (4.5 HD + 1 CON x 1)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 13 (10+1 DEX+2 Natural Armor)

            Attacks (3 Max.): [BAB +1] Claw 10’ +4 (1d6 +3), Claw +4 (1d6 +3)

Evolution Points (3): Reach(1): Claw, Skilled(1): Intimidate, Skilled(1): Perception

            Saves: +3/+1/+2 (+1 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, [1^st Level Feat] Antagonize

Total Skills (4): Intimidate, Perception, Sense Motive, +1 point

At its first level, the eidolon’s pretty weak in combat but works very well as a scout with an effective +13 Perception and as an intimidator with an effective +13 Intimidate.  It can also Sense Motive at +4.  At level 1 it gets the eidolon-perfect Antagonize feat, which it’ll likely be doing pretty often throughout its career:

Antagonize

Action: Standard Action, no AoO

Target: Single opponent within sight with INT 4+

Function: Intimidate check against 10+ opponent’s HD+WIS.  On success, opponent must spend one round attempting to attack you with melee attack, ranged attack, spell, or area spell.  If opponent cannot attack you, effect ends.  If opponent can approach but will take two rounds to attack you, you can extend the effect by one round with an immediate action once.  On failure, no effect.

The idea’s for the eidolon to spend actions getting enemies to waste their attacks on an infinitely-resurrectable creature.  That said, initially an eidolon’s pretty weak and could easily die in a single hit.  It does have natural reach, though, which lets it attack enemies which are not adjacent to it to help it stay out of direct combat.

2: Summoner (Spirit Summoner) 2, +1 Hit Point

            BAB: +1

            Base Saves: +2/+3/+3

New Feats: Bond Senses

Skills(3): Stealth, Swim/Climb, Use Magic Device

New Spells:    0^th Level- Mage Hand

1^st Level- Snowball

Base Spells Per Day: 3 Lvl. 1

2: Spirit Summoner’s Ancestral Eidolon (2 HD)

            HP: 11 (4.5 HD + 1 CON x 2)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 15 (10+1 DEX+4 Natural Armor)

            Attacks (3 Max.): [BAB +2] Claw 10’ +5 (1d6 +3+1d6 bleed), Claw +5 (1d6 +3+1d6 bleed)

Evolution Points (4): Reach(1): Claw, Skilled(1): Intimidate, Skilled(1): Perception, Bleed(1): Claws

            Saves: +4/+1/+3 (+1 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion

Total Skills (8): Intimidate 2, Perception 2, Sense Motive 2, +2 points

Level 2 gives the summoner Snowball, a ranged touch attack spell that deals 1d6 cold damage per level up to 5^th and staggers on a failed save (stagger means an affected creature can only perform a single action on its turn), and Bond Senses, which the summoner can use it see out of its eidolon’s eyes.

The eidolon gets slightly more powerful with a bleed effect on its claws, adding 1d6 damage each turn, and evasion which allows it to completely avoid Reflex-save effects on success (though its Reflex saves are pretty shitty).

3: Summoner (Spirit Summoner) 3, +1 Hit Point

            BAB: +2

            Base Saves: +3/+4/+3

New Feats: [3rd Level Feat] Extend Spell

Skills(3): Stealth, Use Magic Device, +1 other

New Spells:    0^th Level- Mending

1^st Level- Enlarge Person

Base Spells Per Day: 4 Lvl. 1

3: Spirit Summoner’s Ancestral Eidolon (3 HD)

            HP: 16 (4.5 HD + 1 CON x 3)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 15 (10+1 DEX+4 Natural Armor)

            Attacks (3 Max.): [BAB +3] Claw 10’ +6 (1d6 +3 +1d6 bleed +push), Claw +6 (1d6 +3+1d6 bleed)

Evolution Points (5): Reach(1): Claw, Skilled(1): Intimidate, Skilled(1): Perception, Bleed(1): Claws, Push(1): Claw

            Saves: +4/+2/+3 (+1 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion, [3^rd Level Feat] Combat Reflexes

Total Skills (12): Intimidate 3, Perception 3, Sense Motive 3, +3 points

Level 3 has the summoner getting Extend Spell, a metamagic feat which lets it apply an extra effect to spells.  Extend lets it increase a spell’s level by 1 to double its duration.  The summoner also gets Enlarge Person, a spell perfect for boosting the capability of its eidolon and party members.  Large creatures do more damage with their melee and natural attacks, and get reach which lets them attack enemies that are not adjacent to them (which the eidolon already has on one claw, increasing to 15’ reach when enlarged).

The eidolon gets its neatest defensive ability which is the push evolution, a free combat maneuver which pushes enemies away on a successful roll.  The idea here’s that the eidolon Antagonizes, getting a melee enemy to charge in to attack it, then as it approaches, the eidolon uses its reach to hit the creature with an attack of opportunity, potentially pushing it backward and ending its action to no effect.  The eidolon also gets Combat Reflexes, granting it an extra attack of opportunity per round to assist that tactic (normally creatures can only make one attack of opportunity per round).

4: Summoner (Spirit Summoner) 4, +1 Hit Point

            BAB: +3

            Ability Score Increase: CHA +1 (20)

            Base Saves: +3/+4/+4

New Feats: Shield Ally

Skills(3): Stealth, Use Magic Device, +1 other

New Spells:    2^nd Level- Haste, Glitterdust, (Spirit) Spiritual Weapon

Base Spells Per Day: 5 Lvl. 1, 2 Lvl. 2

4: Spirit Summoner’s Ancestral Eidolon (3 HD)

            HP: 16 (4.5 HD + 1 CON x 3)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 15 (10+1 DEX+4 Natural Armor)

Attacks (4 Max.): [BAB +3] Claw 10’ +7 (1d6 +4 +push), Claw +7 (1d6 +4), Hoof +2 (1d4+2), Hoof +2 (1d4+2)

Evolution Points (7): Reach(1): Claw, Skilled(1): Intimidate, Skilled(1): Perception, Push(1): Claw, Hooves(1): Legs, Ability Increase(2): STR

            Saves: +4/+2/+3 (+1 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion, Combat Reflexes

Total Skills (12): Intimidate 3, Perception 3, Sense Motive 3, +3 points

Level 3’s Haste, which you’ll always use forever and, with the Extend Spell feat and the trait that reduces Haste’s effective spell level slot it’ll always be doubled in duration meaning it lasts eight rounds here and scales up.  Glitterdust’s an amazing area-effect spell that blinds on a failed save and reveals invisible creatures.  Shield Ally’s a bonus to AC and saving throws when your brother’s next to you, which makes sense.

The eidolon’s getting stronger and more resilient, though I still wouldn’t send it out to fight more robust enemies than mooks or maybe a wizard.

5: Summoner (Spirit Summoner) 5, +1 Hit Point

            BAB: +3

            Base Saves: +3/+4/+4

New Feats: [5^th Level Feat] Toughness

Skills(3): Stealth, Use Magic Device, +1 other

New Spells:    2^nd Level- Invisibility

Base Spells Per Day: 6 Lvl. 1, 3 Lvl. 2

5: Spirit Summoner’s Ancestral Eidolon (4 HD)

            HP: 26 (4.5 HD + 2 CON x 4)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 18 (10+2 DEX+6 Natural Armor)

Attacks (4 Max.): [BAB +4] Claw 10’ +8 (1d8 +4 +push +1d6 acid), Claw +8 (1d6 +4 +1d6 acid), Hoof +3 (1d4+2 +1d6 acid), Hoof +3 (1d4+2 +1d6 acid)

Evolution Points (8): Reach(1): Claw, Skilled(1): Intimidate, Skilled(1): Perception, Push(1): Claw, Hooves(1): Legs, Improved Natural Attack(1): Claw, Energy Attacks(2): Acid

            Saves: +6/+3/+6 (+1 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion, Combat Reflexes

Total Skills (16): Intimidate 4, Perception 4, Sense Motive 4, +4 points

Toughness and Invisibility bump up the survivability of this character even further- your hitpoint range at this point is (5-40 base +5 favored class bonus + 10 from 14 CON + 5 Toughness) 25-65, which is enough to live through some violence.  Invisibility’s nice on your eidolon to make it stealthy too.

The eidolon finally gets one of my favorite evolutions, Energy Attacks, which add 1d6 acid damage to all its natural attacks (so, all of its attacks).

6: Summoner (Spirit Summoner) 6, +1 Hit Point

            BAB: +4

            Base Saves: +4/+5/+5

New Feats: [Hex (6^th)] Fortune

Skills(3): Stealth, Use Magic Device, +1 other

New Spells:    2^nd Level- Summon Eidolon

Base Spells Per Day: 6 Lvl. 1, 4 Lvl. 2

6: Spirit Summoner’s Ancestral Eidolon (5 HD)

            HP: 32 (4.5 HD + 2 CON x 5)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 18 (10+2 DEX+6 Natural Armor)

Attacks (4 Max.): [BAB +5] Claw 10’ +9 (1d8 +4 +1 M.F. +push +1d6 acid), Claw +9 (1d8 +4 +1 M.F. +1d6 acid), [Rend (1d8 +6 +1 M.F. +1d6 acid)], Hoof +4 (1d4+2 +1 M.F. +1d6 acid), Hoof +4 (1d4+2 +1 M.F. +1d6 acid)

Evolution Points (9): Reach(1): Claw, Skilled(1): Intimidate, Push(1): Claw, Hooves(1): Legs, Improved Natural Attack(1): Claw, Energy Attacks(2): Acid, Rend(2)

            Saves: +6/+3/+6 (+5 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion, Combat Reflexes, Devotion, [5th Level Feat] Martial Focus: Natural (Weapons)

Total Skills (20): Intimidate 5, Perception 5, Sense Motive 5, +5 points

Hexes!  Hexes are a special class feature you’re borrowing from the witch which lets you do kind of a magic trick as often as you want, though normally only once per day per person.  Fortune’s one of the best ones- it lets a creature roll twice and take the higher result on an upcoming roll, which initially takes some timing but has incredible utility and is relatively rare.  The spell Summon Eidolon lets you bring your eidolon out in a round even if it’s been killed for one round per level.

Fortune

Action: Standard Action, no AoO

Target: Single creature within 30 ft.

Function: Grant a creature good luck for 1 round.  The target can call upon this good luck once per round, allowing him to reroll any ability check, attack roll, saving throw, or skill check, taking the better result.  They must decide to use this ability before the first roll is made.  At 8th level and 16th level, the duration of this hex is extended by 1 round.  Once a creature has benefited from the fortune hex, it cannot benefit from it again for 24 hours.

The Eidolon’s still improving and gets Martial Focus to add a point of damage to all its attacks and qualify for some pretty neat tricks a little later.

7: Summoner (Spirit Summoner) 7, +1 Hit Point

            BAB: +5

            Base Saves: +4/+5/+5

New Feats: [7th Level Feat] Hellcat Stealth

Skills(3): Stealth, Use Magic Device, +1 other

New Spells:    1^st Level- Unfetter

                        3^rd Level- Black Tentacles, Greater Invisibility, (Spirit) Heroism

Base Spells Per Day: 6 Lvl. 1, 4 Lvl. 2, 2 Lvl. 3

7: Spirit Summoner’s Ancestral Eidolon (6 HD)

            HP: 39 (4.5 HD + 2 CON x 6)

            Form: Biped [Claws, Limbs (Arms), Limbs (Legs)]

            Speed: 30’ land

            AC: 20 (10+2 DEX+8 Natural Armor)

Attacks (4 Max.): [BAB +6] Claw 10’ +10 (1d8 +4 +1 M.F. +push +1d6 acid), Claw +10 (1d8 +4 +1 M.F. +1d6 acid), [Rend (1d8 +6 +1 M.F. +1d6 acid)], Hoof +5 (1d4+2 +1 M.F. +1d6 acid), Hoof +5 (1d4+2 +1 M.F. +1d6 acid)

Evolution Points (10): Reach(1): Claw, Skilled(1): Intimidate, Push(1): Claw, Hooves(1): Legs, Improved Natural Attack(1): Claw, Energy Attacks(2): Acid, Rend(2), Skilled(1): Perception

            Saves: +7/+4/+7 (+5 against Enchantment spells and effects)

Feats: Darkvision 60’, Link, Share Spells, Antagonize, Evasion, Combat Reflexes, Devotion, Martial Focus: Natural (Weapons)

Total Skills (24): Intimidate 6, Perception 6, Sense Motive 6, +6 points

Hellcat Stealth is a feat-granted Hide In Plain Sight (at -10)  as long as it’s normal or brighter light.  Stealth is entered through movement, and in this case it’s like a move-action or five-foot step Invisibility in certain circumstances.  This character, at level 7, has (7 points + 3 class + 3 DEX + 1 trait + 3 feat) a reasonable +17 base modifier on Stealth rolls before items or other enhancements, with an extra +2 in dim areas and +1 in hilly or rocky areas which gives it a pretty good chance to stay stealthy.  Black Tentacles is a good area-disabler spell, and Greater Invisibility’s one of the best spells in the game- it’s invisibility that doesn’t go anywhere, even if you do something!  Heroism’s a good free spell, but probably isn’t worth a 3^rd-level Summoner slot.

The eidolon gets Skilled: Perception, which bumps its perception up by +8, making it a pretty potent lookout in addition to its Antagonizing disposable fighter role.

8: Summoner (Spirit Summoner) 8, +1 Hit Point

            BAB: +6/+1

            Ability Score Increase: CHA +1 (21)

Attacks (4 Max.): [BAB +6] (-1 size) Claw 10’ +13 (1d8 +8 +1 M.F. +push +1d6 acid), Claw 10’ +13 (1d8 +8 +1 M.F. +1d6 acid), [Rend (1d8 +12 +1 M.F. +1d6 acid)], Hoof 10’ +8 (1d6+4 +1 M.F. +1d6 acid), Hoof 10’ +8 (1d6+4 +1 M.F. +1d6 acid)

Evolution Points (11): Skilled(1): Intimidate, Push(1): Claw, Hooves(1): Legs, Energy Attacks(2): Acid, Rend(2), Large(4)

Suddenly Fortune becomes fucking amazing, as the hex Soothsayer lets you time Fortune to exactly when a character needs it.  You use Fortune on every character in the party, including yourself and your eidolon at the beginning of the day and then when it feels appropriate they can roll twice on whatever they fuck they want!  You also get Fly as a spell and can just about certainly Use Magic Device with 100% success using your (8 points + 3 class + 5 CHA + 3 feat) +19 base unbuffed modifier, making you as utility-capable as the amount of wands you’ve collected.  It's also important, at this level, to have a wand of Hex Vulnerability, which you can use as a loophole to the once-per-target-per-day limiter of Fortune (creatures can voluntarily fail Will saves).  Your allies ought to be willing to pitch in for this.

Soothsayer

Action: (none)

Target: Evil Eye/Fortune/Misfortune/Retribution Hexes

Function: Can choose to delay the effect of specific hexes.  The hex then takes effect the next time the target makes a roll that could be affected by the hex or is affected by an action that could be modified by the hex, whichever comes first (ignoring actions that are not in combat and actions that have no penalty for failure). The duration of the hex begins on the same round as the action that causes it to take effect.
The hex is wasted if it is not triggered within 24 hours.

Eidolon bumps up to Large now!  This is where it starts getting mighty- all its attacks increase in size and gain reach and it gets more hitpoints.  Thematically, in the cases of both reach and its new size, you could say something like your brother’s the same size but developed a fighting style and philosophy of moving around constantly.  Or magic!  I dunno, whatever you wanna do.  He takes up four times as much space now, though.

With the Eldritch Heritage: Cloak Of Shadows, you now have the ability to add a short-term Stealth bonus to yourself or others.  It’s a prerequisite for something good.  Ancestral Weapon’s a cute ability that adds the power to summon a weapon- since we’re in a campaign where guns are common, they count as martial weapons and so you could summon a gun that you instinctually know how to use.

The eidolon gets Spell Resistance, greatly improving its resilience in general.  There’re a lot of abilities and effects even aside from spells that have to penetrate spell resistance to affect something- make sure to start asking.  Multiattack, Power Attack, and the new five-natural-attacks-per-round cap make it more of a violence powerhouse.

All skill foci improve to +6, boosting Stealth (now +23) and Use Magic Device (now +24), and Chant means hexes can be extended by one round with a move action.  A round, then, would look something like: Standard-Action Black Tentacles to debilitate, Move-Action Chant to extend Fortune on all allies within 30’, Five-Foot Step Hellcat Stealth to suddenly go invisible in normal or brighter light, which is some pretty bad-ass action economy, especially since you still have an eidolon to fuck around as.  Overland Flight’s a great spell and ought to be cast on yourself and probably your eidolon at the beginning of every day.

Eidolon itself’s still slowly improving, and now it has a bite attack.

Shadow Well is actual Hide In Plain Sight, plus a kind of shadow teleport!  This is why you got Cloak Of Shadows- now you can go invisible during movement ANYWHERE.

Shadow Well

Action: Stealth / Standard

Target: (none) / Willing Ally or Allies within 60’

Function: You can use the Stealth skill even while being observed and without cover or concealment, as long as you are within 10 feet of a shadow other than your own.  In addition, when within an area of darkness or dim light, once per day as a standard action you may choose to switch places with a willing ally within 60 feet, who must also be in darkness or dim light. At 13th level, you can instead switch the positions of two willing allies, each of whom must be within 60 feet of you. Unless otherwise noted, this travel is identical to dimension door. You may use the ability one additional time per day at 17th level and 20th level.

Icicle Dagger’s a cute first-level spell now- at eleventh level it’s an eleven-minute frost dagger with the returning property.  Dimensional Anchor’s a good spell to keep around in case the boss guy you’re fighting can teleport to escape (at later levels a lot of things can).  You can also Teleport to escape!

Eidolon gets Cut From The Air, a way to use an attack of opportunity to completely deflect a ranged attack from itself or from you, if you’re adjacent.  He’s still pretty robust besides.

Possessed Hand is kind of cute!  I thought it’d be especially thematic- by this point I imagined you’d know your eidolon bro’s a ghost and you’d be relatively familiar with your other dead family.  It can and probably should be swapped out for Extra Evolution Point, though I didn’t denote the extra point on the eidolon’s stats.  Its actual function is a feat tax for Hand’s Autonomy at level 15.

Also the eidolon’s Huge now, for reasons of war.

Spellcut!!  Spellcut’s great for an eidolon- it lets it use its BAB as its saving throw against some Reflex-targeting spells or rays once per round.

Hand’s Autonomy’s why you woulda taken Possessed Hand.  It’s capable of a lot.

Hand’s Autonomy

Action: Varies

Target: You, sort of

Function: When you are unconscious, paralyzed, asleep, or stunned, your possessed hand can still act on your behalf in a limited fashion. The hand uses your statistics when performing any action in this manner. The hand can’t take attacks of opportunity, but can draw attacks of opportunity from actions it takes. The hand can perform the following actions each turn on your initiative count.

• The hand can retrieve or pick up an item or weapon as a standard action.
• The hand can attempt any of the following skill checks at a –4 penalty: Disable Device, Escape Artist, Heal, Sleight of Hand, or Use Magic Device.
• The hand can knock you prone as a free action, and drag you while you’re prone at a speed of 5 feet as a full-round action.
• The hand can perform any other action appropriate for a hand and an arm, such as pouring a held potion into your mouth or awakening you from a sleep spell.
• The hand can make a single melee or ranged attack with a light or one-handed weapon as a full-round action.

The hand’s for emergency situations- of particular note is its ability to Use Magic Device as you with a -4 penalty, as in using a wand to heal you or even a wand to make you invisible.  Diehard’s better but Diehard doesn’t let you do shit paralyzed or stunned.  In fact, I can’t think of anything else that does!  Another thing worth mentioning is that it can act while you’re asleep, though since it doesn’t look like it can perceive much other than you I can’t think of how to utilize that in a powergaming fashion.  Anyway, it’s great but get another Extra Evolution Point otherwise.

Honestly kinda just coasting here.  The character’s built solidly enough, with enough tricks and spells and action economy, and you’ll know how to play it by now, assuming the game’s going any further.  This is about the normal level at which a campaign ends.  Hand’s Autonomy was your capstone.

Eidolon should have an Eidolon-Anchoring Harness (6000 GP) as soon as possible.
Eidolon should have a Sharding Amulet Of Mighty Fists (+2 equivalent, 16000 GP) after that.

Summoner should have a Lesser Rod Of Quicken Spell (35000 GP) after that.
Other equipment, like resistance and stat-boost stuff, is of course of use, but not as specifically-useful.
