From Compendium of Worldly Lore
he foe hunter has but one purpose in life: to kill creatures of the type she hates. She is willing to pay any price or risk any danger to prevail against this hated foe. Her blade is anathema to such creatures, and her body is more often than not proof against their attacks. Though her hatred of this enemy is boundless and unending, it is not unthinking or rash. She lives to put an end to her hated foe, but she does not throw away her own life needlessly.
The foe hunter’s path is open to any creature, good or evil. Some hunt humans or even celestials; others hunt the foulest spawn of the underworld. Foe hunters can be fierce allies against formidable enemies or implacable opponents dedicated to killing those the heroes love.
A character can choose this prestige class more than once but must select a different hated enemy and start again at 1st level each time. Levels of different foe hunter classes do not stack when determining level based class features.

Class Features
All of the following are class features of the Foe Hunter.
Weapon and Armor Proficiency: A Foe Hunter is proficient with whatever they were already proficient with prior to taking levels in this class.
Hated Enemy: At 1st level, the foe hunter chooses one creature type that she has already selected as a favored enemy to be the target of her hatred. This choice determines what kind of foe hunter she becomes—orc hunter, giant hunter, or the like. The choice of hated enemy is irreversible.
Rancor Su: The foe hunter can deliver a powerful blow to her hated enemy. Once per round, on her action, she can designate one of her attacks against a hated enemy as a rancor attack before the attack roll is made. A successful rancor attack by a 1st-level foe hunter deals +1d6 points of extra damage. This amount increases by +1d6 points for every two additional foe hunter levels the attacker acquires. Should the foe hunter score a critical hit with a rancor attack, this extra damage is not multiplied. The extra damage from a rancor attack applies even if that hated enemy is immune to critical hits.
With a sap or an unarmed strike, the foe hunter can deal subdual damage instead of normal damage with a rancor attack. She cannot, however, do subdual damage with a weapon that deals normal damage in a rancor attack, even when taking the usual —4 penalty.
Hated Enemy Damage Reduction Ex: At 2nd level, the foe hunter can shrug off 3 points of damage from each successful attack by her hated enemy. This damage reduction increases by 2 points for every two additional foe hunter levels she has. Damage reduction can reduce damage to 0, but not below that. Hated enemy damage reduction does not stack with any other damage reduction the character has.
Hated Enemy Spell Resistance Ex: Beginning at 4th level, the foe hunter can avoid the effects of spells and spell-like abilities that would directly affect her, as long as they originate from her hated enemy. Against such effects, the foe hunter has spell resistance equal to 15 + her foe hunter class level. This stacks with any other applicable spell resistance the character may have.
Death Attack Ex: At 10th level, the foe hunter can make a death attack against a hated enemy that is denied its Dexterity bonus to AC (whether or not it actually has one). This ability functions like the assassin's death attack, except that the foe hunter need only make a melee attack that successfully does damage, not a sneak attack.
