So you basically wanted a energy version of a Vandal, but with higher damage, 2 knockbacks, and a much bigger range, not to mention that you did state anything about uses, i'll just assume that it have infinite uses.
hmm, honestly, i think it might be pretty good.... maybe a little OP, so i'd probably cut some of the regen damage, and energy damage, and maybe cut the electric damage by 50 or so.
And maybe, on top of that, if it still seems a little op, maybe cut it to 2 uses and make it L-M.
In general, its a bit too op and probably a bad idea......
