BOOST SPELL-LIKE ABILITY [GENERAL]
Source: Book of Vile Darkness
One of the creature’s spell-like abilities is harder to resist than it otherwise would be.
Benefit:The saving throw Difficulty Class (DC) of a boosted spell-like ability is increased by +2. A creature’s spell-like abilities can be boosted three times per day, though the feat does not allow the creature to exceed its normal usage limit for any ability. Thus, if a succubus chooses to boost its suggestion ability, it can use a boosted suggestion up to three times that day.
Special: This feat can be taken multiple times. Each time it is taken, the creature can apply it to one of its spell-like abilities to give three additional uses of the feat per day. Thus if a Succubus took two feats in one ability, it could boost the ability six times per day, or if it took it once in two abilities it could use it three times per day in each.
Special: In the case of Warlocks this means selecting either Boost: Invocations or Boost: Eldritch.
