The Boomerang is a secondary weapon in Momodora I.
This weapon of Australian origin is sort of a multi-tool in Momodora I. It travels in a curve-shaped motion and will return to the player after a brief moment. It is frequently used throughout the game to hit switches that would normally prevent your advance through the game. Since it is a secondary weapon, it can be used while using the Magic Leaf or any sort of projectile weapon, adding some extra damage to your attacks.
The Boomerang, other than the projectile weapons, ignores any sort of obstacle it flies through. This allows the player to finish of enemies in difficult spots without getting in danger.
