That's... a couple resets ago when we first summon the boss in Edge of Madness.
I think it's pretty funny and Kisaragi really has spoken for all of us.
Turns out this boss is only a stupid giant undead troll and we zerged him without much problem. :)
All you have to do is run away when he turns his size from XL to XXXL, hits around 10000 dmg which hurts like hell. :p

We've done two Edge of Madness bosses in ZG now, after we down the other two, we'd actually totally owns ZG. :)
