You can channel your arcane energy into a bolt of power that is baneful to evil creatures.
Celestial Sorcerer Heritage (PH2) , sorcerer level 1st,
As a standard action, you can expend a spell slot to create a 60-foot line of energy that deals damage only against creatures with an evil alignment. The bolt deals 1d8 points of damage per level of the spell slot spent to activate this ability. A Reflex save (DC 10 + the level of the spell slot expended + your Cha modifier) halves this damage. This is a supernatural ability.
