Mmm, Mycus needs its own mutation tree.
But it should be quest related. Like… after a certain amount of time, you should be able to infect survivors with fungus, and then have them be your thralls for a while, to which you bring them back to a fungal tower and they are converted into a ‘guide’ like yourself. Then they go around like a normal survivor but they spread fungus here and there.
When you do this, you should be rewarded with a beneficial mutation.
[Mycus Proselytization]
You breathe out to release the gift of our intentions, and those that hear it understand and become. (Activate to spray a cloud of spores from your nose and mouth that infects the nervous system of a sentient creature, turning them friendly)
(After you do so, the fungus says)
“Bring them to us, and they will become a guide like you”
[Fungal Mend]
Fungus grows on your skin to plug open wounds, and set bones. This can also be used on any creature that is Mycus.
[Marloss Colony]
Spread our influence, that which germinates within you. (You vomit up a colony of fungus, similiar to how you did so when you ate Marloss Berries]
END GAME
[Fungal Protectorate Local Colony]
Fungus grows thick around your body and face, protecting you from harm. Holes remain open for your orifices and sensory organs so that you may work with clarity. [You can no longer wear armor or clothes, but you grow your own anyways.]
[Adapted Metabolic Ecosystem]
(Radiogenesis, except it feeds you rather than heals you. You suffer no damage or mutation from radiation)
[Deformed]
[Strong Scent]
