Hardened Sap

Hardened Sap is a furniture item that periodically spawns critters when placed. It is also used to summon Floracadas and to craft an end-game boss-summoning item.

The type of critters spawned by Hardened Sap is determined by the biome it is placed in. The ground block it sits on does not affect the result, so changing the floor beneath it will not change the critters it produces. If a Hardened Sap is placed in a sub-biome, it spawns the same critters as one placed in the main biome it belongs to.

A notable exception is that a Hardened Sap placed on a Crystal Block always spawns critters from the Shimmering Frontier, regardless of the biome around it. This makes Crystal Blocks unique among placement surfaces for this item.

Because the critter type depends on the biome, Hardened Sap is best treated as a biome-specific spawn source rather than a universal one. Place it where you want the corresponding biome critters to appear, and use Crystal Blocks only when you specifically want Shimmering Frontier critters. This behavior makes it useful both for collecting critters and for preparing materials tied to Floracadas and its boss-related crafting use.

• Biome placement controls the spawned critter type.
• The block underneath normally does not matter.
• Sub-biomes inherit the critters of their parent biome.
• Crystal Block overrides the biome and forces Shimmering Frontier critters.
• It can be used to summon Floracadas.
• It is part of the crafting chain for an end-game boss-summoning item.
