This boss is definitely busted! Pillars either don’t work or they spawn at the bleeding edge of the platform where you can’t get behind them. Please fix this ZOS!!! Destroys my entire run whenever this boss shows up. 3/4 threads to zero instantly! BS
I'm also interested to know if it's intended to get the curse that needs to be cleansed right about when the explosion is supposed to happen. So, I have to choose whether to run to the cleansing pad or stay behind the pillar. This happened on several occasions. Sometimes I was lucky and the pillar spawned right in front of the pad. So, I was able to cleanse not leaving the pillar. On other occasions the pad was far away and when I cleansed I got killed by an explosion because I did not have time to get back behind the pillar.
So, is this mechanic overlap supposed to happen? And if so, how should it be managed? To my knowledge both of them is one shot death.
You need to cleanse the debuff when your screen turns blue. Best to keep him near a pillar at all times if you can. When he has a damage shield, you just need to damage him like normal. Only the animation that looks like he's casting rally is the one that will kill you.
