Repairs the durability of equipped weapons, armor, and rings. They will not repair broken items.
- These powders are usually used during long periods of online gameplay, such as PvP and co-op (being summoned as a phantom).
- If a player is summoned into another host's world, the durability damage is carried over. When the character returns to their world (after defeating an area boss, death, or the death of the host), the durability damage continues to carry over. Therefore, enough co-op playing without refreshing durability at a bonfire could call for repair items.
