At the last boss, I rolled "need" for an item in a dungeon, but before the roll was finished, I left the instance because I thought everyone rolled, but one person didn't.

I ended up not getting the item. I'm wondering if I left and won the roll, would I still be able to get the item? Saying that the last person didn't roll a "need" also.

Thanks.

Ticket a GM - if nobody else rolled need you should be entitled to the loot.

I'm not sure they will be able to help you, as their logs may not store loot rolls etc - but it's always worth a shot as if you didn't receive it from the dungeon (and it was LFG) it's lost

If it was a random dungeon that you found using the dungeon finder with people from different realms, then I do not think it is possible for you to retrieve the loot.

If you want to double check though, run back to the instance that you were just in, and see if the instance has respawned. If it is a fresh instance, then I think you are 100% out of luck.

You could always try talking to a GM too.
