About Slime Core
Slime Core is a boss drop in Sailor Piece. Open-world bosses spawn on 5–8.5 minute timers across islands like Sailor Island, Shibuya Station, Hueco Mundo, Valentine Island, and Ninja Island — while summoned bosses on Boss Island (Ice Queen, Qin Shi, Gilgamesh, Ichigo, Rimuru) require Boss Keys, cash, and gems. The capped supply from boss timers and low drop rates keeps Slime Core trading at around 300. The stability is marked unstable — prices have been swinging, so expect offers to vary by trade partner. Demand sits at unknown (6/10); trades usually close but may require a small sweetener.
