Usage
The Bonemerang is a unique type of bow as it acts like a boomerang. Firing a bonemerang launches a bone that travels forward for up to 10 blocks before returning. The bone deals arrow damage, benefit from bow enchantments and can trigger, but doesn't deal knockback. When it's returning, it deals double damage.

While in dungeons, the bone benefits from the Bouncy Arrows and Double Arrows perk, meaning it has a chance to summon arrows that inherit the bonemerang's damage.

If the bonemerang hits a wall or strikes more than 10 enemies, the bone shatters, rendering it unusuable for 3 seconds, while the bone is flying and/or shatters, a ghast tear takes it's place in the inventory.

When the bone is returning, it'll try to return to the owner even if they move, causing the bone's trajectory to follow you while moving. this can be used to hit more enemies.

Trivia

 * The Bonemerang is a reference to Marowak's signature move in Pokémon.
 * Throwing it at Thorn stuns him for 3–5 seconds, making it easier to shoot him with the Spirit Bow.
 * If you stop stunning Thorn he will begin to move very fast, making it very hard to shoot him.

Tips

 * Multiple Bonemerangs can be used to maximize damage by firing Bonemerangs while others are still returning.
 * When returning to the user, it can move 20 blocks before disappearing.
 * You can apply a sword rune cosmetic to a bonemerang, as long as it does not already have a rune. If the bonemerang does already have a rune, you cannot apply a sword rune.
