The 1’st boss of the Warmaker’s dungeon doesn’t deal any damage. Not to thralls or you, the similiar blue boss later in the dungeon doesn’t deal damage either.
He is just a bit ill, winter cold you know..
Uh? That seems to be new. Official or modded server?
I had that bug with his version in the UC. PS5.
It affects all wight bosses. It is caused by them wielding Carnage, which is intended for players only and adds a debuff that multiplies damage by 0 if it is being held by an NPC.
However, they’ve always used that weapon and inflicting 0 damage is recent. So the reason why this bug is newish is because the previous bug that allowed people to exploit Set Antidotes to cure corrupting equipment was fixed a couple patches ago.
The debuff that prevents NPCs using Carnage and other specific player-only weapons was flagged as poison. Undead are immune to poison, so the wight bosses ignored the debuff. Set Antidote cures poison, so it cured the debuff (which is also what caused the corruption). Funcom fixed the exploit by removing the poison flag, but as a result, wights are no longer immune to it.
Tephra, knower of things. Impressive!
This is what her forum rank should look like 
“knower of things, Asura’s chosen”
Damn… the things that you know!
Good knowledge. Be a very simple fix in FC side to make a NPC only carnage for those bosses with the old setup. Like 5 mins of work lol.
Xevyr says it would be even easier than that. The IronKing (that is what it is called internally) debuff is set to multiply damage of any NPC by 0, but you can just change that to any thrall, which is what the debuff was intended for.
