Eldritch Blast

A warlock who has learned to harness the magical energies around him can manipulate them into a directed blast that emanates from his fingertips. This eldritch energy can be used to attack enemies and can sometimes be imbued to impart other debilitating effects.

While not actually a spell, it is still considered a spell-like ability.

Zixxywix's eldritch blast is florescent green, symbolic of the acidic breath that his copper dragon ancestor possessed.
