Lithium (Subnautica)
Lithium is a rare material.
It can be found Mushroom Forest biome and the Jelly Shroom Caves. It looks like a purplish quartz crystal and may be hard to spot due to its size and may look like a dark patch on the seabed.
In the Mushroom Forest biome, the majority of Lithium can be found near Mushroom tree structures or on their "bark".
In the Jelly Shroom Caves, Lithium can be found around the large Jelly Shrooms and in shale deposits, albeit rarely.
