Hi, I was doing the quest in zafaria where you have to disguise as an elephant, but what if your polymorph wears off before you get to the part where you need it? can I not finish the quest?
nothing happens; the disguise is only to get you through the door (according to the quest dialogue).
i actually just did this quest on my myth/ice team yesterday and can confirm for a fact that you can still complete it once your disguise wears off. it's only good for 9 minutes, and you can't complete the instance in 9 minutes, so there's your answer.
