I want advice to balance this out:
Fungal Folk
Ability Score Increase: Your constitution score increases by 2, and your wisdom score by 1.
Age: Fungal Folk can live eternally but they would need to find a new host body every ~150 years or so. They usually mature in a week as that is the usual amount of time it takes for a medium-sized creature to be fully under the control of the fungus.
Alignment: TN Fungal Folk only care for themselves but will often create loose rules among each other if there is enough of them in a place.
Size: Fungal folk are usually the size of humans but slightly taller due to added fungal mass. Your size is medium.
Speed: Your base walking speed is 30ft.
Fungal Body: You are immune to all poison damage. If a beast bites into your body, they have to take 1d6 poison damage.
Fungal Network: Whenever you are in contact with a fungal network (the DM decides) you gain advantage for all your rolls including initiative. You can also communicate with any fungal creature anywhere as long as it is touching the same fungal network.
Languages: You can speak common, and fungal
some extra ideas I have for this race are:
Fungal Knowledge: Gain proficiency in alchemist's tools and gain advantage when using mushrooms and fungus as ingredients.
Fungal perseverance: If killed, you can come back to life. To come back to life, a piece of your fungal mass needs to be transported to a corpse, this needs to be done in a certain amount of time depending on the size of the piece: Whole mass 7 days, torso-size 3 days, leg-size 1 day, arm size 12 hrs, hand size 3hrs. After the piece has latched onto a body it takes 5+2d10 days for the fungus to infest the new body and make the character be playable again. All this needs to be done by a third party like another PC or an NPC. The same rules are used for when your body is too old or unusable for any other reason.
