Adaptive Casting Feat
You have a few extra eldritch tricks up your sleeve.
Key ability score 19, caster level 7
Select three spells from class spell lists you can cast spells from. They must be at least 1 level lower than the highest spell level you can cast. Once per day, you can cast one of these spells as a spell-like ability. Each time you gain a caster level, you can change which three spells you have selected with this feat.
