Type of dmg , lab lvl 68 boss

Im pretty sure my character had almost every possible defences I could have . Immune to poison , immune to bleed and corrupted blood , res overcap , spell suppression , armor , evasion , ailments negation . Still this boss managed to just drain my whole life in like 3-4 seconds. I wonder if I forgot something or it was just stat diff? The only thing I think I was lacking was chaos res

Some of Izaro's mechanics, if allowed to reach their full potential, juice him to levels that can be really difficult for a level ~70 character with average campaign-end/early mapping gear to deal with. His slams especially can get to the point where they will pancake you kinna regardless if you stand in them, unless you're geared well past the point where you should be doing Merciless Lab.

I'm not familiar with any degen effects though, unless the Goddess Tether is a thing during the Izaro fight? Did you get a green beam fastened on you from the green ghost lady hovering over Izaro? If so, you died to her degen because that stuff is ridiculous. You're supposed to break the tether by running away from the Goddess, but I thought she only did that as a solo map boss sans Izaro. Hm.

I do remember the green thing casted by the ghost , it was alwyas in the pattern where I stand on him and on the green cirlcles , then I get teleported and start loosing HP, probably my negations worked properly but he then casted his long range slam that ended me before I got to regen life . I thought the green circles teleport you though

Ah. That green teleport drops you on top of Labyrinth traps. Lab traps are almost all degen effects, and they can be no joke if you're weak against degen. Have to stay out of the circles and avoid the traps.
