Requires the library mod Hybrid.

Disabled Durability is a mod (a Hytale Java plugin) that removes the durability mechanic from the game. Similar to Stardew Valley and Terraria. This won't be for a general playthrough, but can be used if you're in need for a bit more of a relaxed playing style. Without having to worry about your tool, weapon or armour breaking.

Configurable: ( how do I configure? )
disableItemDurability (default = true)

Showcase:
Any tool or weapon can be used without its durability going down:
