Lucifer Rotsac

HarvestMaterial

Overview

An oily, glowing bulb. Has a heartbeat. Required in 4 crafting recipes: Floating Support, Grease, Rubber, and Glowstick. Its presence in multiple recipes makes it a recurring material demand throughout the early and mid game. As an intermediate material, Lucifer Rotsac represents processed potential — raw resources transformed into something more useful but not yet a final product. Subnautica 2's crafting depth comes from these middle-tier items that require planning to maintain in adequate supply.
