You're welcome! Just to be clear though, you
do not have to expand to the Quest Outpost in order to use it. If you're just talking about expanding to it in order to decorate the area around the Quest Outpost, to celebrate its arrival with flowers of all colors and noble hedges, then please carry on
Nope, dragons of any level can go on Dragon Quests, so long as they're the right dragon for the job. Players do have to be level 11 in order to access the Quest Outpost, however.
Thanks for the questions!
