By completing different tasks in the game, you gain experience. The more experience you have, the higher your level will be and the more opportunities you will have in the game.

By exploring rooms, completing quests, helping a friend, or trading with creatures on the map, you will earn experience points. When you collect a certain amount of points you will level up.

Every time you gain a level, your energy is fully replenished, and you get a bonus - 1 diamond.

Besides, your maximum energy capacity is increased:
Level 1-10 — by 10 points;
Level 11-150 — by 5 points;
Level 151+ — by 1 point.

As you level up, you will unlock new content: access to new rooms, new quests, and various in-game features like guilds and competitions.
