Maximize Spell

Metamagic

Your spells have the maximum possible effect.

Benefit: All variable, numeric effects of a spell modified by this feat are maximized. Saving throws and o­pposed rolls are not affected, nor are spells without random v­ariables. A maximized spell uses up a spell slot three l­evels higher than the spell’s actual level. An empowered, maximized spell gains the separate benefits of each feat: the maximum result plus half the normally rolled result.
