The Terrarium Ripple Knife is a craftable, non-consumable Hardmode throwing weapon that can autofire. It rapidly throws rainbow colored energy knives that are not affected by gravity and inflict the Terrarium Backlash debuff that is characteristic of all Terrarium Weapons. The knives have a constant rainbow colored after image that does not inflict damage to enemies.

Like most non-consumable throwing weapons, using this weapon builds up an exhaustion meter that appears below the player. Not using the weapon will make the meter slowly go back down. However, if it becomes completely filled, the user will be inflicted with the Exhaustion debuff, causing all non-consumable throwing weapons to deal massively decreased damage for some time. The meter resets after the debuff ends.
