Subterranean crimson blobs bouncing through upper dirt strata
The Red Slime is a subterranean gelatinous creature that inhabits the dirt layer just below the surface and above deep stone caverns. Endowed with 35 life and 4 defense, this crimson blob deals 12 contact damage in Classic, 24 in Expert, and 36 in Master mode. While resembling surface slimes in movement, its higher resilience makes it a sturdier foe for miners exploring early shallow sinkholes.
Extracting gel deposits along shallow cave shafts
Because Red Slimes bounce with steady rhythms, holding down wooden broadswords or using starter bows repels them effectively without taking damage. Slaying a Red Slime yields Gel at a 100% chance in quantities of 2–5, providing dependable fuel for crafting Torches and campfires during underground mining runs. It also holds an elusive 0.01% rate to drop the Slime Staff summon.
Trivia
- Red Slimes inhabit the transitional dirt underground zone rather than deep stone caverns or grassy surface biomes.
