EMPOWER SPELL [METAMAGIC]
You can cast spells to greater effect.
Benefit: All variable, numeric effects of an empowered spell are
increased by one-half. An empowered spell deals half again as much
damage as normal, cures half again as many hit points, affects half
again as many targets, and so forth, as appropriate. For example, an
empowered magic missile deals 1-1/2 times its normal damage (roll
1d4+1 and multiply the result by 1-1/2 for each missile). Saving
throws and opposed rolls (such as the one you make when you cast
dispel magic) are not affected, nor are spells without random
variables. An empowered spell uses up a spell slot two levels higher
than the spell’s actual level.
