Oh, I know.  Though considering Psychic Warriors only even gain one power per level, it's little different from Expanded Spell Knowledge.<br/><br/>In other news, how smote would I be if I happened to find a way to reduce the ability damage cost of those spontaneously persisted spells to zero? :D  Yeah, some stuff's just crossing the line, but the idea of being able to pile one two-day buffs just because I can amuses me.
