What are the pros and cons about Moscovia dungeon having a quest?

[GM-Rahice]

You can use Fly Wings on the airship to avoid getting seen, use Hide, or something like that as well. You can log out of it, like Evo said. You also do NOT have to kill the monsters, you can sit on the ship for the whole 5 minutes.

NEVER USE A BUTTERFLY WING. This will make the quest screw up.
