Signature Spell

[FlimFlam]

What does this feat do and what are the requirements? I dun furgot. I making a character and don't have the book with me that it is in (Tome and Blood I believe).

Any help would be great.

from the FRCS:

prereq: Spell Mastery

Benefit: each time you take this feat, choose a spell you have mastered with Spell Mastery. You may now convert prepared arcane spells of that spell's level or higher into that signature spell, just as a good cleric spontaneously casts prepared spells as cure spells
