Prerequisites
Benefit
As a swift action, you can imbue your weapons with elemental energy. For 1 round, your weapons deal an additional 1 point of energy damage. The type of energy damage depends on your bloodline: acid for earth, cold for water, electricity for air, or fire for fire. For every 5 levels you possess, this bonus increases by 1, to a maximum of +5 at 20th level.
