Frosthail

The Frosthail is a Hardmode staff which drops from the Lunatic Cultist. It fires an ice mist, similar to the Lunatic Cultist, which fires ice shards in six directions before disappearing. It inflicts the Frostburn debuff.

Trivia

 * The Frosthail, along with the Fireblast, Shockstorm and Starthrower, resemble the Lunatic Cultist's four primary attacks; these being his homing fireballs, ice balls, lightning orbs and ancient lights.
