I need help creating a new Knack
A player had an interesting idea for a mossling character, but it seems it would require creating a new Knack for them.
He envisioned his mossling hunter being able to dip blowgun darts into their flesh to poison them before use.
While the symbiotic flesh feature is just esthetic, I thought that was a cool idea, and told them I would be looking into designing a knack for them.
All I have so far is the concept that his body could produce toxins/poisons/venoms/psychedelics that he could use.
But I'm not sure how to implement this concept, specifically.
Thank you for any help, advise, suggestions.
*Final design would be posted for sharing*
