What is my Level?
Your level is a sign of your progress.
Your level is reflected on the badge in the upper-right corner of the town.
As you play, you'll collect XP (experience points), which increase your overall level.
Reaching new levels unlocks new content.
The level reflected on your profile's level badge is the highest you can level up your heroes (see XP Potions).
When raiding other players dungeon's you're paired against players of a similar level.
