Hyphae Patrol: Gossamer Cliffs

Don't exit the chamber. Talk to [object=334880] to get transformed into a fae ring.

Fun quest but rather annoying if you happen to be just behind somebody who clears everything before you do, so you can't have any mobs.

This one can be a little buggy. If you're riding and your quest tracking says you're still at "0/1 Talk to Marasmius" you won't get credit for any attacks. Dismounting or abandoning didn't correct the problem for me; I had to dismount, abandon, re-log and re-take the quest.

UPDATE: All of Marasmius's riding quests can bug like this. I found that if I take the quest and exit/re-enter the ring, then the "let's ride" step works.
