Tricky Spell Mastery

You are able to quickly modify your mastered spells when you cast them trickily.

Prerequisite(s): Spell Mastery and one or more metamagic feats, tricky spells class feature, 1st-level wizard

Benefit: Whenever you cast a spell that you have mastered with the Spell Mastery feat as a tricky spell, you may spontaneously apply a single metamagic feat (other than Silent Spell or Still Spell) you have to that spell. You may not apply a metamagic feat which would normally raise the level of the spell Greater than the highest level of spell that you can cast. (When applied with the tricky spells ability, Silent Spell and Still Spell do not increase the level of the spell.)
