The Abandoned Slime Staff is a Hardmode summon weapon that is dropped by Astral Slimes after Astrum Aureus is defeated. When used, it summons a rocky Astral Jelly slime minion, which bounces near the player and fires lasers at nearby enemies. If the player strays too far away from the slime, it will equip an armored jetpack and fly to catch up with them. When the slime is summoned, it will immediately occupy all of the player's remaining minion slots. For each minion slot it occupies, its damage and size are increased. Additionally, holding this weapon increases the player's jump speed by 10%.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Abandoned Slime Staff has over a Ruthless one is knockback.


  • When summoned, the slime's damage is multiplied by: 1 plus log8 of the player's remaining minion slots. The damage value is rounded to the nearest integer. The slime's size is multiplied by: 1 plus log10 of the player's remaining slots.
    • For example, if the player had 4 remaining minion slots when the staff was used, the resulting slime's base damage would be 93. 56 * (1 + log8(4)) = 56 * (1 + 0.66667) = 56 * 1.66667 = 93.33, rounded down.
      • The slime would be approximately 1.60206 times its base size. (1 + log10(4) ) = (1 + 0.60206) = 1.60206
  • If the player has the Frog Leg equipped, the jump speed bonus granted by holding this weapon is reduced to 5%.


  • This weapon and minion is based on the Astrageldon Slime, a removed boss which was reworked into Astrum Aureus, hence the theme of abandonment in the name and flavor text.
    • To further the reference, the weapon and minion feature a yellow and purple palette similar to the Astral Meteor's before it was redesigned into a full biome.
    • The tooltip's usage of the words "heaven" and "disgust" are references to the titles of the Astral Infection's various themes which contain the word "Heaven" and the Astrageldon Slime's theme, Cosmic Disgust.
    • The minion piloting an armored jetpack that resembles Astrum Aureus is a reference to a gif where Astrum Aureus' sprite opens up to reveal the Astrageldon Slime controlling it.
  • The weapon's hooked shape resembles the vanilla Slime Staff.
