Rextroy has soloed a current tier raid boss from Sepulcher of the First Ones. In this video he shows exactly how. You can check out the full version here: Solo Dausegne

The add spawns, the stacking tank debuff as well as a potential berserk. Luckily, when I did some testing on the encounter area to see if I could bug the pathing of NPCs, I noticed that the adds are surprisingly slow, similar speed to a basic NPC. Also their main damage ability won't be cast until they are in melee range with you! Even better, kiting allowed the tank debuff to run out, which means the boss… might be soloable? I got Ipanic and Kaarani to test run the encounter with me, just to see if there was any berserk.

After 10 minutes, Total Dominion is cast. This makes the boss get mana really quickly (but it is not a massive damage boost, as I feared). This leads to Disintegration Halo being cast VERY frequently.

Since we are tanks, we are able to survive it without too many issues! However the boss will also cast Staggering Barrage quite often (about once every 30 seconds). Which is a bigger problem, because without cooldowns, it is hard to survive alone. We needed some speed to outrun the adds, but the less speed we have, the closer we gotta be to the edge of the arena.
