Energy drain

Energy drain is a spell easily cast using a magic conduit, if not, it is extremely demanding and often backfires. The spell is rather simple, you drain energy from anything you see around you to either cast a spell you couldn’t because it was already used (upon dm agreeing), amplifying and changing a spell’s damage type, or releasing all the energy in a sudden burst of power in the targeted direction (if controlled, AC determined by dm). The strength of this spell depends on what energy you drain and how much you drain. The more you take, the harder it is to use and it rarely kills or even truly hurts anything when draining. The real danger is the release.
