The Viruling is a Hardmode enemy that spawns in the Jungle surface during the day after Golem has been defeated. It hovers through the air towards the player, and inflicts the Plague debuff on contact.
- The Viruling cannot fire any projectiles, so any non-melee attacks are useful for killing it.
- It appears to be a Derpling afflicted with the plague, although its behavior has changed as a result.
- The Plague also seems to have made it much more machine-like.
