A righteous sentinel who makes a covenant against undead vows to restore any animated corpse he encounters to its natural state of death, and destroy any residual undead energy in the process. Although these righteous sentinels recognize that not all undead are evil, some are quite willing to destroy neutral and good undead along with all the evil ones.

Skills: The righteous sentinel with the covenant against undead adds Knowledge (religion) (Int) to his list of class skills. In addition, whenever a righteous sentinel with a covenant against undead uses Knowledge (religion) to identify or gain information about undead, he receives a bonus on the check equal to 1/2 his righteous sentinel level (minimum +1).

Covenant Powers: A righteous sentinel with the covenant against undead gains the following abilities as he increases in level.

If the save is successful, a 30–foot burst of positive energy is released, healing living creatures or damaging undead caught within the burst for a number of hit points equal to his righteous sentinel level + his Charisma modifier.
