I recently picked up a quest from the mages guild that requires me to find mummy wrappings. after searching in Castle Necromoghan for hours i think i have found my prize.

it seems to be a purple casket/sarcoughagus sp?

whenever i click on it i take damage.

exactly what am i supposed to do?

Take it too the quest giver?
Edit-oh

manwhocomesaround:I think you have to click on it to pick it up.I think that's what he means. Not clicking it in inventory. Although I stand to be corrected.

It's not in a sarcophagus. If you have cleared the entire dungeon and didn't find it, then it may be that it is located under a trapdoor. You may have not noticed this trapdoor since it should be closed. To open it, you have to find a skull which is located on a wall near a pit. Once you click the skull, the trapdoor (which is not near the skull) should open. I can't tell you exactly where to find the trapdoor and the skull though. But I remember that since Castle Necromoghan is one of the main quest dungeons.

Ah, Castle Necromoghan [Freeman].

Anyway, the room with the trap door is somewhat like this: It's a fairly large room with an elevated walkway spanning three sides of the room, you enter the room on this elevated platform through a single door. There's a ramp leading down to a lower level, half of which goes under the ledge you started on (I believe there's also banner tapestries hanging from that face of the ledge, or the wall above it). To your left is a door, and in there is a dead end containing a trapdoor.

You will know when you've found it because it will just disappear when you activate it - no inventory prompt.

Aren't you looking for fresh mummy wrappings? Your quest target should be a mummy. You'll find it in its inventory after you kill it.

Try not to get stomach rot
