Empower Spell Edit
You cast spells to greater effect
Player's Handbook page 93, Metamagic Feat
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 1½ its normal damage (roll 1d4+1 and multiply the result by 1½ for each missile)
Saving throws and opposed rolls (such as the one you make when casting Dispell Magic) are not affected, nor spells without random variables. An empowered spell uses up a spell slot two levels higher then the spell's actual level.
