Flower of Frost

The Flower of Frost is a Hardmode Magic weapon dropped from a Mimic in the Underground Snow biome. Functionally similar, though superior, to the Flower of Fire. It shoots a slow, non-piercing ball of frost that bounces up to seven times (dissipating on the eighth). Its projectile is much less affected by gravity than the Flower of Fire, cannot bounce on platforms, and functions in all liquids. It has a 50% chance to cause the Frostburn debuff.

Tips
The reforging cost is extremely low, giving the opportunity to get the Mythical modifier without consuming much gold.

Trivia
It's likely a reference to New Super Mario Bros' Ice Flower.
