Slam two electrons together and you get energy. Slam enough of them together at once (enough actually means like three or four -- it wouldn't take much.) and you get a devastating wave of concessive energy akin in nature to a 'sonic boom', capable of fusing sand into glass, knocking down buildings, and destroying anything living in its path. This technique can achieve devastating force for a radius of two blocks. Anything outside of this radius will have diminishing effects.
