Supernatural Transformation

Type: General
Source: Savage Species

You convert a spell-like ability to a supernatural ability.
Prerequisite: Innate spell-like ability.
Benefit: One of your innate spell-like abilities becomes a supernatural ability. It is no longer subject to spell resistance, though it can still be suppressed in an antimagic field. Using this ability does not provoke an attack of opportunity. The number of uses, if limited, does not change. The effective caster level equals your total Hit Dice or the effective caster level of the original ability, whichever is higher.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take it, it applies to a new spell-like ability
