The Cursed Dagger is a Hardmode non-consumable rogue weapon that is dropped by Clingers. It inflicts Cursed Inferno to any enemies hit and can pierce through 2 enemies or bounce twice off of tiles. It disappears upon its third impact. Like the Shadowflame Knife, it is heavily affected by gravity. It is the Corruption counterpart to the Ichor Spear.
Its best modifier is Unreal.
