Damage dealt is calculated per daemon: daemonATK/2 - bossDEF (and then there's some randomness factor, idk)

You'll get a feel for boss defense and how it increases, I think. Hard to give exact values due to the randomness factor and the fact that data isn't the same from event to event (zynga probably buffs the CQ bosses a bit each event, understandably xD)

If you use 3x attack: 3*daemonATK/2 - bossDEF (and then some randomness factor idk)
