Just a heads up to everybody, but if the exclusive material multitask functions with king's innate DW, king is actually a decent finisher. 342 attack on a say 920 atk King is effectively a little over double damage.(1142² vs 800^2). That means the puny 210% 1 hit finisher is closer to 420-450%.

I could run the full analysis if you want, but at a glance, Olive does 1 hit at 1175 and a 4.8 mod. King would do 2 hits at 1142 and 2.1 mod. Olive: 1175² * 4.8=6.6mil
King: 1142² * 2.1*2=5.5mil

While there are a multitude of different sides to this whole analysis, and Olive comes out on top in many ways, King does quite significant damage. Especially when you don't own many tmr's. (at 600 attack with 100 attack weapons, the boost from multitask is 283% damage.) He is very much the poor-mans version of a gun toting finisher.
