Hellkite

The Hellkite is a craftable Hardmode broadsword that auto-swings and is the direct upgrade to the Fiery Greatsword. It is larger than most other swords of its tier, and upon hitting an enemy it inflicts the On Fire! debuff and summons a damaging geyser of flame on top of each target struck, dealing additional damage.

Trivia
