FoK with the interupt and the poison
The good news is that since 3.2.2 FoK no longer interrupts and does 30% less damage than it did before.

AoE like that used to cause me alot of pain, but I soon learnt to dump an earthbind totem, insta-GW and grab some distance.

I love AV, but I really wish they'd introduce an 80's-only version of it.
