Chaotic Spell Recall

(Fiendish Codex I: Hordes of the Abyss, page 84, DnD 3.5)

[Abyssal Heritor]

A few choice spells never stray far from your mind.

Prerequisite

Any one Abyssal heritor feat, ability to prepare and cast spells

Benefit

Once per day, you can recall one spell with the chaotic descriptor that you had prepared and then cast. The spell is then prepared again, just as if it had not been cast. You recall the spell as a swift action. The spell can be of any level you know, and you can recall the same spell or a different spell every time you use this feat. You gain an additional daily use of this ability for every two abyssal heritor feats you possess.

Special

Your mind frequently fills with chaotic thoughts, imposing a -2 penalty on Concentration checks
