Story: Gnome berserker used berzerk Spin. My dwarven priest and human warrior were in range. Proc sequence is:

berzerk spin
acrobatic flip success trigger (dwarven priest)
I moved the gnome and dwarven priest away
spiked mail triggered (human warrior)
damage proced correctly for human warrior and the gnome even though out of range.

The question here is how aoe untargetted damage should resolve when the instigator has moved out of range.
