Well i was working on getting all 10 dragon preists masks for the lols and i realized i don't have the Otar the mad mask <.< nor do i ever remember getting it....... :S
I've gone back to Ragnvald.. not there honestly i don't ever remember getting it anyone else had this :3?
I picked it up yesterday. Checked and have it in inventory now. If you truly lost it, I believe there is a remedy by using console... But search for that remedy somewhere else or this thread will end up in different subforum.
EDIT: I just wonder how you could forget about it Dragon Priests are most epic fights/"mini"-bosses in Skyrim for me Masks are treasured
Well like all dragon priests when you loot him, there will be only like 3 items on him. Only mask is shown with arrow on the left (dude has it equipped). If you did not loot it, Otar should still be there with the mask (can't confirm but I think he will because he is no associated with any outside quest). If you looted it and accidentally sold it then it seems there is no fix since you say it happened some time ago so saves won't help. OR maybe you dropped it somewhere Try looking through your chests and houses.
Well that means that you looted the mask when you killed him. I've seen a lot of corpses do not despawn even after a month if they are not stripped clean of loot. Can't confirm this is for every mob either but I still have few dead stormcloaks at fort amol dead for well over a month in game.
So I guess it means you sold it by accident or dropped it somewhere. Maybe even in some dungeon if you were making space for something else. It has to be one of these two. It didn't disappear from inventory or YOUR chests for sure.
Their are 9 dragon priests masks total. You need to find 8 dragon priests and aquire their masks. Once you have all 8, you can use all of them as part of a quest that creates the 9th mask.
No respawn. I entered the Vokun throne room and coffin "popped" but no priest. He was dead at the place I killed him behind the coffin. Empty, no loot.
He was first I killed a looong time ago. Dungeon respawned, but not the priest.
So even if you get Narkiin you can't complete the quest without Otar mask...
