Yateveo Bloom

The Yateveo Bloom is a craftable Pre-Hardmode flail. It throws out a rose flail that inflicts the Poisoned and Venom debuffs. The flail pierces indefinitely and is affected by gravity. If the player holds down left-click, the flail will drag alongside the player, dealing damage to any enemy it contacts. Pressing or holding right-click will fire a short flower spear that does two-thirds of the flail's base damage. Only the right-click attack will have True melee boosts applied to it.

Trivia

 * Yateveo is a mythical man-eating tree found in the book "Sea and Land".
