Gensokyo/Willow Staff

The Willow Staff is a Pre-Hardmode summon weapon that summons one of Sekibanki's many heads to follow the player and attack enemies. The head periodically shoots two lasers from its eyes, each of which does the full listed damage. Like other minions, the flying head is invincible and follows the player for an unlimited amount of time, unless the player dies, exits the world, summons a replacement minion or cancels the buff.
