• When you sell armor or tools, durability affects how much money you will get.
• * If durability of a tool is at 50%, you will get 50% of the price when you sell it.
• * This prevents people from buying a tool, using it to 1%, then selling it for the entire price.
• * You can sell multiple tools from your inventory by doing, say /sell woodenpick 3.
• * * This will send you 3 lines in chat, each saying what the durability of each of the 3 woodenpicks was, and how much they each sold for, as well as your total sale.
