i think someone is supposed to silence/stun the large scale AOEs.

i fought it there 2-3 times, and haven't seen any issues.
Now, that teleporting bull, in West Noscea though...I fought it once, and rather not do it again. It was on Island of Umbra...duno how it even got there, or why it's an issue? Maybe it's just me, but if there's a psionic bull, that can blink around....i'd just leave it there, on the island...
