Off-meta strat, I tried with metal spiked metal boots sledge build, the damage is pretty good, but it's quite often to missed compared to Taser, even with off-balance debuff. Although in sledge build, normal attack already good enough to kill most light armored guy anyway.
Gonna continue my unarmed monk tomorrow and check if the damage is worth more with that 20% unarmed damage boost thingy (although my monk is agi-oriented, not str-oriented :/)
