Pugilist: Arm of the Destroyer

Demolish will also deal as much damage as a 3-hit Rockbreaker if the full DoT can be used.

Demo is 420 while a 3 hit RB is 390. So you need 4 enemies to beat a single demo in potency. But that's also not the correct way to look at it. It takes 21sec for demo to hit 420p. In that time you could use 3 rockbreakers, so you consider that when deciding if you should put demo up. I did the math a while ago back at the start of Midas and if I remember correctly, you need at least 5 enemies before a rockbreaker can take priority over demo. So basically you should have at least one demo going at anything less than 5. But once you hit 5 the rotation changes to AoTD, maintain twin snakes, rockbreaker, with no demolish.
