I have been musing over a new race lately. My friend that first introduced me to MTG runs a wicked fungus deck and hope this captures some its moldy goodness.

THALLID TRAITS

Ability Score Increase. Your Dexterity score increases by 1, and your Constitution score increases by 2.

Size. Thallids stand around 4 feet tall and weigh between 70 and 90 pounds. Your size is Small.

Speed. Your base walking speed is 25 feet.

Fungus. You do not need to breathe. You can go up to a week without eating but require the normal amount of water per day.

Spore Cloud. You can use your reaction to expel a cloud of thick spores. The cloud extends 10 feet in all directions around you. The area covered by the spore cloud becomes heavily obscured for 1 minute for all creatures except you. Anyone else that begins or ends their turn in the spore cloud must succeed a Constitution saving throw or become poisoned for 1 round. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus.

After you use spore cloud, you can’t use it again until you complete a short or long rest.

Sprout Saproling. Once during a short or long rest, you can spend a Hit Dice to bud a saproling from your body to do your bidding. This functions as the unseen servant spell, but it takes the form of a Tiny saproling. When you reach 5th level, you can use this trait as an action.

Languages. You can speak, read, and write Common and Thallidish. Thallidish is a language that involves trading spores and is impossible for others to replicate, but may intuit hints of meaning by scent (for example, a peppery smell can connote a sense of anger or frustration).
