It says on wiki that you only get 10% of character’s level? O_o Seems low

I think it’s x% per crafting level you gain, so in total it’s 10 levels.

Ye and, with 8 crafting disciplines to be able to max, you can getv to max level with only crafting (though you need some way to get the resources).

Nice 10 levels uh
Hmf, I’ll have to go look and calculate how much each discipline cost with its most efficient way to level

I believe you can get even more than 10 levels out of it by using crafting xp boosters, which can be found in black lion chests or purchased with gems.

...or do those only boost the crafting level?

It’s roughly 10 levels. Many people have reported 12 levels, presumably from bonus XP.
