In regards to Archaons ability. I know that whenever he pins another disc, he deals the area damage. and I know that when another disc pins him, he deals the arcane damage, and I am fairly certain that both at the same time are true (he pins, and someone else pins him, they both cause the trigger separately).
The question is if Archaon becomes pinned by a unit, and the area effect goes off, does it go off again when a second, and potentially third disc then decides also flip on top of Archaon?
