Mod:Leveling

As you use a skill, you gain XP. Gain enough XP, you go up a level in that skill (up to the max for your class), which then gives corresponding boosts to that aspect of your character. For example, go up melee levels and your melee damage, speed and critical chance will all increase. Go up alchemy levels and your buff lengths will extend and potion sickness length will reduce. You start at level 0 in everything, and the max level is currently 50 for crafting and alchemy, with the combat skills determined by class. Basically, at level 20 you'll be as good at everything as you are in the vanilla game, and by level 50 you'll be ... rather more powerful (dealing over double DPS with melee for example). Crafting level makes a huge difference to the quality of prefix you get from crafting new items and reforging existing ones, so it's well worth levelling up if you want to see legendary and mythical items!

Levels top out at level 50, as of beta 10 skills are available at certain levels to players based on their class.
