Leveling

General information
Leveling is one of the main ways of progression within the game. Each level requires a certain amount of exp which can be gained through killing mobs and more ways may be added in the future (such as questions). When leveling up you can equip more items (not implemented yet) and you gain stat points to spend, more information about that here: Stats. For more information on level requirements go here: Equippable items. Note that currently the max level is 500.

Exp
Exp is the requirement for leveling up, if you want to know more about how much exp each mob gives you can look at Enemies. The exp requirement goes up for each time you level up, for level 1 you require 1000 exp, each time you level the requirement goes up with 50 exp. So for level 2 you require 1050 exp and for level 20 requires 2000 exp.
