How to configure proficiency leveling
Navigate to lua/wos/advswl/config/crafting/sh_craftwos.lua
Find the values "wOS.ALCS.Config.Crafting.SaberMaxLevel", and "wOS.ALCS.Config.Crafting.LevelPerSlot"
"wOS.ALCS.Config.Crafting.SaberMaxLevel" determines the max proficiency level anyone could ever reach (Default set to infinite, aka false)
"wOS.ALCS.Config.Crafting.LevelPerSlot" determines how many proficiency levels the player must get before getting a slot for misc items on their lightsaber (Default set to 1)
Example
The following will limit the max proficiency level to 25, and set the levels required to gain 1 proficiency slot to every 5 levels
wOS.ALCS.Config.Crafting.SaberMaxLevel = 25
wOS.ALCS.Config.Crafting.LevelPerSlot = 5
