Location and route

Approach Donut of Worms from a known oxygen point, scan the plant, then check the floor, walls, and nearby fauna before harvesting. If the plant sits in Root Canyon hazards, mark it and return with the right tool instead of forcing the route.

Uses and unlock value

The practical value is plant log, hazard clue. If it supports a recipe, collect only the amount needed for the next craft. If it is a landmark, use it to label the route and connect it to the nearest biome or resource loop.

Risk and scan notes

Good marker for a turn-back point. In co-op, call out the plant name, region, and nearest return marker so teammates can reuse the route without duplicating the scouting work.
