PDK Features
Level	Ability Name	Effect	Uses	Duration
1	Rallying Cry	Grants 1 bonus attack per round.	3	1 round per point of Charisma modifier. If the character has 41 or more hit dice and 5 levels of PDK, then the duration is doubled.

3	Fear	Cast a Fear spell that causes an AC penalty effect of (Hit Dice including LLs + 1) / 8. (The AC penalty does not stack with curse song.) DC check = 15 + PDK levels + Strength Modifier + Dexterity Modifier.	PDK level.	2 rounds per PDK level.
4	Knightly Valor	Passively grants you Tier 1 LL AB regardless of control class and a number of attacks a pure fighter would have.
4	Oath of Wrath	Grants critical immunity versus the racial type of the enemy chosen for the duration. Grants a re-roll on failed ability checks (NOT saves) vs. the targeted race.	1 + 1 at PDK 5	PDK level x2. (PDK level x4 at level 41.)
5	Final Stand	Instead of granting temporary hit points, it brings all allies in a Large radius to their feet, removing knockdown effects. Radius of 5m + 1 per 6 points of Charisma modifier, up to 10m at 70 Charisma. Usable even while the PDK is knocked down.	3

Can only ever be a splash class due to the maximum five level limit.
Since several abilities take charisma into consideration, it makes more sense to use this class with higher charisma characters like Paladins, Blackguards, Bards or even Smiters.
Knightly Valor is valuable for classes with Tier 2 LBAB progression like Assassin, Red Dragon Disciple and Shadowdancers.
