Throwing Knife

Throwing Knives are sold by the Merchant during Blood Moons, and may also be found in generated chests. They are thrown Nonexplosive Consumables category weapons that can damage up to two enemies before either falling or breaking.

Throwing knives are affected by gravity - they will arc similarly to Shurikens when thrown. When they hit two enemies or a wall, there is 50% chance that they will break. If they do not break, they can be picked up again.

Throwing knives are considered a compromise between the Shuriken (which can hit many enemies with one weapon) and Bones (which can only hit one), with a damage per hit below that of bones but above that of Shuriken.

Throwing Knives can be upgraded with one Vile Powder to make Poisoned Knives. Poisoned Knives are even more deadly than regular Throwing Knives because they can inflict the Poisoned debuff on enemies.
