Ancient Light casting animation.

The Ancient Light is a Hardmode magic weapon. It launches three primordial light projectiles that bounce off of tiles infinitely and home towards nearby enemies. Upon contact with an enemy, or after not hitting an enemy for many seconds, it creates a large blue explosion, dealing area-of-effect damage and inflicting the Granite Surge debuff to all enemies caught in the blast, dealing additional damage and lowering defense.

This weapon is obtained from the Treasure Bag of the Lunatic Cultist in Expert Mode only.
