Sunfury

The Sunfury is a rare drop flail category weapon from Bone Serpents in The Underworld. It's an orange flail that emits light during attack and deals 40 points of damage, but can hit multiple enemies at once and one enemy twice (or multiple times in the case of a boss). The Sunfury has a 1/100 chance to drop from Bone Serpent.

When the ball goes too far from the player or hits a block, it quickly retracts.
