Beam of Lightning

Costs 3 Energy to cast every full combat round (6 seconds) it is up

Caster creates a beam of lightning that lasts as long as the casters concentration does. This beam has to be between two conductive objects, making lightning flow through them. Anyone that touches the objects casting the beam will be subjected to 2d4 lightning damage, and anyone who touches the beam will take 2d8 lightning damage. The lightning can arc to any conductors within 5 feet of the beam, and can continue arcing like that through any number of people. However, if the beam is broken by a nonliving nonconductor, or either point of the beam is moved so the beam cannot be completed, the spell will break on its own. This spell can hurt the caster.
