Durability and craft suggestions for changes and implementations in the game

I am concerned with the game mainly with the blocking of equipment after using, this happens with the items of “boss” and epic mobs but I should keep this for the equipment of low rarity and also for all the equipment sold in the store of the NPCs.

another point that i want to address is the implementation of the manufacturing system monsters drop minerals, parts of equipment and other items and will be used to manufacture equipment and tools for work and the manufactured equipment will have durability and can be fixed only by players gathering some manufacturing materials and that if they break items they will be “lost” and cannot be fixed but can be used as raw material for manufacturing
