fabled emp is competely immune to regular damage weapons. It's like the first emp before the major changes in the game. I think all the mobs in ssra have a small immunity to regular weapons. Not that it matters, anyone spending time here when then can kill vt fabled isn't going to spend time in ssra. I couldn't even imagine myself multiboxing cursed or anything like that for twinks.
Well the question would be: are the new shissar found in TBS vulnerable to this weapon. Does it become a 22/45 to them. That would make it, hands down, the best weapon against Shissar in the game.
