TooltipSummons the pinnacle of slime evolution
Did you ever hear the tragedy of Goozma The Amorphous Deity? I thought not. It's not a story the Tyrant would tell you.
It's a Overseer legend. Goozma was the ultimate evolution of all slimes, so powerful it could influence the cells that comprise all other slime.
It could even create new slime gods, with affinities to the world's biomes.
The energy of the world is a pathway to many abilities some consider to be unnatural.
It became so powerful the only thing it was afraid of was losing it's power, which eventually, of course, it did.
Unfortunately, Goozma's power grew so great for it to become a temporal anomaly.
A temporal anomaly which a power beyond our universe had no choice but to erase, so that it never existed in the first place.
Ironic. The very growth in power which made Goozma a deity in the first place, was also the cause of its demise

The Ionized Jelly Crystal is a craftable Expert Mode-exclusive pet summoning item. It summons a pet Goozma, which initially starts alone, but gains up to four orbiting slime deities at a time given certain conditions. If the player enters a biome which has a corresponding slime deity, Goozma will gain a slime deity which will orbit around it. The appearance of these deities is affected by biome, and one will change to match the biome the player is currently in. Once Goozma has amassed four deities, the earliest deity summoned will be overridden by the next biome the player enters. If the world is experiencing a Blood Moon, Frost Moon, Pumpkin Moon, Solar Eclipse, or Boss Rush, all four deities will transform into their respective event's forms and will not change again until the event is over.


A list of the forms the orbiting deities can take and their conditions can be found here:

  • The Goozma pet is based on the Goozma boss from the Emphatic Untamed Calamity mod.
    • The pet was coded by Seraph, the creator of said mod.
    • The item's recipe heavily borrows from the Gelatinous Amalgamation, the item used to summon Goozma.
    • The item's tooltip references the cancellation of Emphatic Untamed Calamity, as well as the Tragedy of Darth Plagueis the Wise.
    • The slightly higher drop chance given to the Astral, Crimulan Blight, and Ebonian Blight Slimes are a reference to Goozma's fight containing Astral, Crimulan, and Ebonian Deities.
  • The item has by far the longest tooltip of any item in the mod.
