Grass Spirit

A base spirit that can be summoned by the MC for 20 stamina if they chose Grass Affinity at the start, summoned Grass Spirits will come with the Grass Affinity trait. If you selected UniqueStarter for added difficulty at the start, you won't be able to summon them and the one you are given will not have Grass Affinity.

They can also be summoned by Rhita for 20 stamina, whose Grass Spirits will come with an additional Berserker trait, encouraging you to raise them into aggressive roles. Berserker is a rare and powerful trait, so you can consider Rhita's Grass Spirits a source of Berserker to fuse to other units as well.

Base spirits are generally weak and will be priority targets for most of their training cycles. It's advised to keep them safe in combat encounters.

Like all base spirits, Light Spirits can be reshaped upon hitting their level cap, increasing their Max Level and some genes but going back to level 1.

Grass Spirits and their evolved forms all have Photosynthesis, making them advantageous economically. Creatures in particular cost nothing at all to keep around so you can keep as many as you want.

Grass Spirits can be evolved into Grass Cats, which evolve further into Grass Steeds or Plant Fox Girls, Plant Spiders which don't evolve further, or a specialized base species Plant Girl.
