The Basilisk is a Hardmode enemy found in the Underground Desert biome. They move quickly and highly resist knockback, making them a very formidable enemy to fight against. They have a rare chance of dropping Sturdy Fossils and the Ancient Horn, which summons a mount version of the Basilisk.
It is essentially a much stronger Antlion Charger.
- When fighting Basilisks, fighting them from above or with weapons that deal high knockback is a good idea.
- In mythology, Basilisks are reputed to kill with their gaze or poisonous breath. Fortunately, they have no such abilities in Terraria.
