===Fiend’s Favor (Su)=== 
Three times per day, an Abyssal Chancellor can grant a touched willing creature a +3 bonus to one of its ability scores. This bonus stacks with any other bonus the creature may already have and lasts for one day. When the effect expires, the creature takes a -3 penalty to the same ability score for the next day. Another application of Fiend’s Favor not only negates the penalty, but restores the full bonus. While under the effect of Fiend’s Favor, a character receives a -3 penalty to any will save made to resist a spell or effect cast by the Fiend of Manipulation. This penalty increases by an additional -1 for each consecutive day the creature has benefitted from the Fiend’s Favor.
