The Liberation domain power gained at level 4 is:
(It can be used 3+1/2 paladin level times per day.)
Agile Feet (Su): As a free action, you can gain increased mobility for 1 round. For the next round, you ignore all difficult terrain and do not take any penalties for moving through it. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
(Unfortunately this character's base WIS modifier is -2, so without WIS-boosting items this ability can only be used once per day. Fortunately, that could be all you need.)
The Travel Domain Dimensional Hop ability gained at level 13 is:
Dimensional Hop (Sp): At 8th level, you can teleport up to 10 feet per [hell knight] level per day as a move action. This teleportation must be used in 5-foot increments and such movement does not provoke attacks of opportunity. You must have line of sight to your destination to use this ability. You can bring other willing creatures with you, but you must expend an equal amount of distance for each creature brought.
Between the two blessings, this character essentially has Freedom Of Movement on at all times, making it immune to a huge amount of impeding effects. Hell Knight Armor allows this character to ignore the movement speed penalty from its Hell Knight Full Plate (see below) from level 7 forward. The Travel domain granted power allows this character to move at an additional 10' per round, making its speed 40'. It'll be neat for the gruff, intimidating tank to be naturally moving faster than the party rogue.
