So apparently the Jelly King has gained a new berserk attack; When this attack is used, he starts spinning madly across the room, shooting several balls of slime that still spawn jellies and the such. Although he does not heal while doing this attack, he's also invincible. Now, the problem? He uses this literally all the time - He simply uses his normal attack once and then uses that. Always repeating the same pattern - Normal, berserk, normal, berserk, normal...
And what's worse is what you see on the screenshot. Apparently devs screwed up hard enough to create a clone of the King - The original one apparently cannot berserk and dies very quickly (maybe on normal speed? Didn't really take notice with all the crazy crap going on), however the second one which appears to be a clone works "normally". The "clone" also had way more health than the original King.
It might just be that we were using two-star gear, but it was pretty much impossible to kill him like this. We got down to about 80EN revives before giving up. We did manage to kill the "original" King, although it dropped no loot.
So whether a glitch or not, I'd like some explanation from the devs. The "clone" isn't even the problem - It's simply the new attack that is too strong.
And as a friendly advice, don't really worry about Jelly King right now. This madness is not worth it at the moment.
AWW! Jelly QUEEN!!!
