Full info page to come but heres the basics:

Exp

• Your character gets it from completing quests
• Only you can earn your characters Exp (not gifts, trades, comms)
• When you have enough Exp Points to raise your character's level, you can do so from the 'Level & Stats'  link on your character's profile
• You have to manually hit the button to level up and receive your rewards

Levels

• Raise your character's level by getting Exp points
• Every time your character levels up they get 5 breeding slots
• And 1 stat point to raise stats
• And other prizes :)
• Higher level characters can delve deeper into the dungeon on Dungeon Dives for better loot
• They also will likely have better stats, making them more valuable during Campaigns
• Characters will not be able to get higher than level 2 during Beta
• But at least 5 levels will eventually be available 👍
