Rank and Stamina

Rank is the equivalent of your account level. Your rank dictates what dungeons you can do in game, how many team slots you have, your max team cost, and your max stamina. As you complete dungeons, you'll earn EXP toward a rank up. When you rank up, your stamina bar will refresh to max.
Ranking up will always increase your max team cost, or max stamina, but not both at the same time.

A more in-depth rank chart can be found here. Below is a short list of the features you unlock at each major milestone.
