A broken arrow can be found in certain spawn points, such as in the ranging guild, searching crates, and playing the Fishing Trawler minigame. An Ava's accumulator can also randomly attract one to your inventory. If it is caught during Fishing Trawler, then the player will receive 5 Fishing experience. Broken arrows, along with broken staves and damaged armour, can be repaired at a repair bench in a player-owned house.
The archaeological expert says, "No doubt this arrow was shot by a strong warrior!"
