Zhaitan's Eye Event Mission(Needs rework)
A group of 50+ people will take down the Champion Tank with ease in a few minutes. Of course, there will be sacrifices, and I don’t mean by throwing all NPCs at it.
I don’t think such groups would be frustrated at all. The only groups affected are few to several players that keeps letting the Tank hit anything, including pets, clones, and other summoned NPCs, not just players alone.
Anything it hits makes it “Harder, Better, Faster, Stronger”. It does loses his Frenzy stacks and gets stunned if it swings but misses anyone four times, whether by evading or blocking.
