Naksun 1hp

[Pkmdz]

Was just fighting Naksunn, and after I got him to 1hp he just kept repeating the freezing resist combo that he does around 30% hp endlessly until I lost. He wouldn't teleport out or anything. It went on for 3 minutes. Would show screen shots but this site is telling me that I don't have permissions or something.

Can happen for any boss when you kill them at a certain point during their rotation/mechanic.  Their mechanic still goes through.  You just have to make sure to add in a few hits and prepare an iframe or two.

naksun works that way since you don't kill him, always when he gets to 1, just use any skill that is not parry penetration and he will stop doing anything and you win.

Try to stand in front of him and spam some LMB.
