Ok, from now, 80 fans for the new bosses.

edit: yep, almost 3 full runs needed, so 80 fans will be a must from higher bosses.
And lvl 12 gives 277 headbands, logically following the previous levels.

Man, I'm having to run 130 stam for level 12 and i sometimes miss 6k and have to spend an extra 30 to finish it off. =\ Just not strong enough still.
