Spirit Splinter

Spirit boon

A splinter of especially spirit-touched wood found its way under your skin. Over time, its magic infuses your body with the power of the forest. Leaves might grow within your hair, pigment might shape wooden grain and knots on your skin, and your spilled blood might turn thick and amber-colored like sap.

Barkskin. Your AC can't be less than 16, regardless of what kind of armor you are wearing.

Phytomancy. Once per long rest, you can cast the speak with plants spell.
