God, I hate this dogshit boss so much, mostly because you're forced to take damage, and it's even more cancerous without the mountaintop buffs. With every other boss you can still solo it if your team is getting downed often and clutch a win, but with this boss you're guaranteed to get chipped down eventually, unless it has piss all health left. We only won because we had a wending grace. The boss is entirely doable until he starts freezing the whole arena and not only that but it also lowers your resist to frost when it does proc (guaranteed to happen even with a lot of frost resist buffs) so you're more likely to get frozen next time. What the fuck were they thinking? I give up on this pile of shit and just putting on frost resist relics, maybe those will help.
