The red berry is a collectible food item found in small red berry bushes on the ground in grassy and heavily forested biomes.
While the red berry provides minimal calories and hydration, eating the red berries you find will give you Red Berry Seeds.
Red berry seeds can be grown in the ground, in Large Planter Boxes, or in Small Planter Boxes and watered for a higher yield from red berry bushes, which will provide more red berries and red berry seeds when harvested.
The red berries can then be used on the mixing table to produce a variety of Anti-Rad Teas, Wood Teas, Healing Teas, and Max Health Teas. Due to their flexibility in use, they remain a valuable component till the very end of the wipe.
Once you produce several basic teas, you can combine 4 of the same type to create an advanced tea. Then you may make a pure tea by combining 4 of the advanced teas.
