First, you probably should have posted this in the DragonSpyre section of the forms.
Second, that depends on the way you look at it. DragonSpyre was designed for levels 40-50, but I've had friend there at level 37. I'd recommend doing some sidequests, especially if you get stuck or things in general are too hard. DragonSpyre is a long, hard world, and its better to be overleved than under.
I don't think you are under leveled. It all depends if you think you are ready to take that world on. If the general battles are hard on the street, the boss quests are only more difficult. Try defeating a few monsters and see how well you do. If you leave the battles with an ok amount of health, go for the boss But, if you don't do well, you may want to do side quests in other worlds or maybe complete old dungeons for some more experience to level up a little faster. At the moment, I'm level 42 and still in MooShu because I like to take it one world at a time. Personally, it's a little too stressful for me to travel to several worlds at once. Anyways, hope this helps you out! Fiona IceDust Level 42 Thaumaturge
