Location and route

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

Uses and unlock value

The practical value is oxygen route planning, plant log. 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

Important for safe route notes. In co-op, call out the plant name, region, and nearest return marker so teammates can reuse the route without duplicating the scouting work.
