Damage immun Kitava, the Destroyer in Lava Lake

I'm currently in an unidentified Lava Lake and am fighting Kitava the Destroyer while the Maven is observing. I can see that he has resists Fire damage and I'm playing with RF.
I can understand that he's taking less damage but that he doesn't take any damage at all I find very frustrating. While I know that PoE is inspired by D2 where you could have mobs immun to a damage type, so far it was my understanding that this is not the case in this game. His damage isn't enough to hurt me, but other than leaving the game at least to the character selection, I don't see a way how to leave this encounter and missing out on my map completion. I don't swim in maps yet, so that is another frustrating factor.
Hopefully the devs can look up my fight with my account information to see that went wrong here.

went to clear the rest of the map and I actually managed to get the life bar moving a little bit. Kitava has just too much life regeneration against 19+2 RF and 19+2 Fire Trap

they can't... you need to type /bug in zones where you encounter bugs and provide the # given in threads.

regardless your report isn't a bug, you ran a map with something that lets the boss heal(likely consecrated ground) and you couldn't out damage it... try frost bomb next time.

thanks for the advice. I guess the Frost Bomb is to stop the boss from healing himself. And yes it had consecrated ground. I tried to pick the one spot around the boss where I'm not in it.

It does not matter whether you stand on the consecrated ground or not, only if the monsters do, in which case they are granted 5%/s life regeneration.

That can be a lot when it comes to bosses, but Frost Bomb is good advice. If you can reliably hit monsters often enough, there are also Eater of Worlds implicits on helmets that grant "Enemies you've Hit Recently have X% reduced Life Regeneration rate".
