Boomerang is a Tier 2 weapon and the base form of a series of Unique Weapons. It is a throwing weapon that returns to the player once thrown. It will bounce off any surface it strikes and always return to the character that originally threw it.
Because the boomerang is one handed, players can hold one in each hand. It's unique among throwing weapons because it is not consumed when thrown and can be used over and over.
The Boomerang has a base power of 6 and a 0.6-second delay before you can throw the Boomerang again after catching it.
When upgraded at a Weapon Upgrade Anvil to tier 6, the Boomerang's base power increases to 14. Additionally, the Boomerang's appearance changes to the one shown below.

Apart from the addition of a gold star to the name, no other changes occur as a result of the upgrade.
