Maximize Spell [Metamagic]

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 one-half the normally rolled result.
