Creaking Sap

Sap is a sticky liquid that comes from trees and the creaking heart is the heart of a pale oak tree. My idea is for the creaking heart to be able to drop 1 to 3 drops of creaking sap. Using Fortune would increase it. Creaking sap would be used to repair durability slightly. Think of it as glue, it would be used in the crafting menu with any damaged tool or armor to repair it. Unlike using an anvil, this would cost no xp and it would also be helpful on saving precious resources on repairing enchanted tools. However, it doesn't repair at the same rate as using an anvil or using matching tools in the crafting menu, so more creaking sap is needed. It also doesn't stop there, if used in a brewing stand it could be used to make potions of healing. After all, boiling sap would give you syrup and syrup is sweet and delicious.
