Boss got stuck and I can't leave atlas unique map

Hey

I went into the phaaryl megalith and went through the entire area and on the last boss I'm currently stuck as Incarnation of Death got stuck in The Destroyer

He does attack when I walk away and I attempt to let him kill me so I could reset him but that doesn't hit cause he isn't in line of sight. I've also tried to logout and back in to see if that would fix it but that didn't work either.

So I'm currently hardstuck in this map inside of the boss circle not sure what to do now.

I was able to fix this by having my witchhunter go into the map with me and slowly blast it down with a crossbow
