I hereby present you, Ceaseless Discharge!!!!!!! And a shameless ad for the Chaos Legion covenant, the Str weapons group of awesomeness. The build is pretty basic. It uses the club 2 handed for stunlocking. The shield is purely cosmetic, it represent his spider sisters and it is rarely used. It casts pyros that don't rely much on casting speed. Well, tempest gets a significant boost by Dex, but I think fireball is the one that really needs that speed boost.
