Corrupter Of Worlds Help

I recently leveled-up to level 68 and currently stuck with the "The Temple of Legends" quest.

I tried solo-ing the Corrupter of Worlds (because the wiki suggested that it can be solo-ed by any class), but it seems to have a heal ability that wasn't mentioned in the wiki at all.

I've took its HP down by 4000, and after using his heal ability, his HP was back at 100000 again.

So how am I supposed to kill CoW as a mage? Is there a specific weapon/set that I should be using? I've tried meteor and mana potion spamming but the damage I've dealt was useless when it used its healing skill/ability.

 

He has a heal ability? I believe you mean he can regenerate. :I

 

There's a moment where there are 3 white rings made out of firework entities surrounding its body. That's the time where its health jumps back to 100000. So it's definitely not a passive regen, i think.

 

I have the same problem is there some way I to fix this? my uppercut does 1500 dmg and it's still not enough

 

Find a weapon with air damage. Air shreds through the corrupter's health.

 

I couldn't find a weapon with air damage so I asked an assassin to help me and we killed him.
