Maximize Spell [Metamagic]
Benefit: All variable, numeric effects of a maximized spell are maximized. A maximized spell deals maximum damage, cures the maximum number of hit points, affects the maximum number of targets, etc., as appropriate. Spells without random variables are not affected. A maximized spell uses up a spell slot three levels higher than the spells actual level. An empowered, maximized spell gains the separate benefits of each feat: the maximum result plus one-half the normally rolled result.
