Something like this is an example of kk being stupid, we stunned it too much so it couldn't attack anyone, so it healed 24k, then did green next attack on me instead of tank, he voked it and tried to run out of room, therefore bypassing damage from it, but was off by a few squares, it then swapped to mage phase, but I ended up dying anyway in the end. Something like that's very rare though, and I really didn't expect it to happen :/
The KK is such a clunky and glitchy boss. I really don't like it.
