This page will explain the Skill system
The Skill system is an MMO-type progression system. It provides players with a way to level up and gain rewards through various activities that fit into categories such as Combat, Farming, Mining, and more.
Upon leveling up, players are rewarded with keys to crates, money, and stats such as crit damage, crit chance, defense, and more. Additionally, leveling up unlocks various abilities such as double and triple drops and less durability damage. All of these rewards can be viewed in the /skills command.
Each level earned in a skill increases certain stats and the chance of abilities to trigger by a few percent. The max level for each skill is 50.
