Sorbet Staff
The Sorbet Staff is a late-Pre-Hardmode weapon that summons a balloon animal to fight for the player. It is sold by the Party Girl for 3 Gold Coins after Skeletron is defeated. The balloon buddy will circle the player's head until an enemy comes into range, then fly out and ram the enemy repeatedly until it's dead. Summoning additional copies of this minion will add additional segments, increasing its damage and attack speed. Like other minions, the summoned balloon buddy is invincible and follows the player for an unlimited amount of time, unless the player dies, summons a replacement minion, or cancels the buff.
Its best modifier is Mythical for the widest array of set bonuses, or Ruthless for the highest damage output.
