In Lugormod, I betatested some new "powers" to use for a coder, including destruction, cloak ,stun, slow, body, etc. most of the powers mentioned in this thread. it didn't work out on an active server and made combat pretty damn tedious. the only people who liked the additions were TFU-loving kiddos, aside from them everyone else despised it honestly, only powers i'd be cool with are destruction and blindness if you balance them right
