In-game description
How to use Corrupted Sap
Corrupted Sap is a summoning item for Nimruza, Queen of the Burrowed Sands. Use it to fight the boss again, for example to farm its drops.
- Go to where Nimruza, Queen of the Burrowed Sands is fought (its arena).
- Place Corrupted Sap on the summoning rune there to make Nimruza, Queen of the Burrowed Sands appear. The item is used up.
Most boss-summoning items are pieces of furniture that you place on the boss's summoning rune; the in-game description of the item says which rune. Where the boss is fought is on the Nimruza, Queen of the Burrowed Sands page.

Corrupted Sap notes
- Nimruza appears when Corrupted Sap is set on the rune inside her dungeon in The Desert of Beginnings.
- Like Hardened Sap, placed Corrupted Sap spawns critters at intervals.
- If you only want critters, Hardened Sap does the same job.
- Which critters it spawns depends on the biome it is placed in.
- The block type of the ground underneath does not matter.
- In a sub-biome, it spawns the same critters as in the main biome that sub-biome belongs to.
- The one exception: placed on crystal blocks, it always spawns Shimmering Frontier critters, whatever the biome.
These notes cover behavior that the game files do not show directly. They are based on facts from the Core Keeper Wiki (Fandom) page "Corrupted Sap" (CC BY-SA 3.0), rewritten in this site's own words.
