Arkarium and the CK

This guy's attacks are ridiculous, lol. Like the poison that does more than my DW's max HP per tick (sets me to 1 each second). And the attack that does more than my DW's max HP (about 45k - probably actually Damage Reflect). And the attack that does max damage to the whole map. And the KO you can only avoid if you tap left and right fast. And two seduces...

Agreed, this seems impossible. My poor lil Wind archer only has 3200 HP. I might as well give up on this now. I reentered countless times, but was dead or seduced or whatever that bar-with-arrows thing is within seconds each time. Once the snake summons appeared it was beyond hopeless to comical.
