I was under the impression that RBF damage was a fixed amount per round, affected only by differing amounts of AC on different minions. But thn I looked at a fight against FTW.

R.I.P. Johnny Was
Against my non armoured minions the damage was closer to 1.7 mill, so the 160 AC on my tank reduces a fair sized amount actually, which was interesting to see. But those amounts against that tank vary quite a bit.
So RBF affected by randomness then?
