These pine needles are blended with a mixture of algae and muck to create a tonic that will leave muscles twitching. Mixing this with a drink creates a vile tasting concoction that when ingested causes muscles to weaken and to not respond to commands from the body. When ingested, the target must succeed on a Constitution saving throw or have disadvantage on Dexterity saving throws and ability checks for 1 hour. To force feed someone this mixture, they must be grappled, restrained, or incapacitated in some way. It then requires an action and a successful grapple check to force feed them the concoction.
Save DC is dependent on potency: DC 13, DC 15, or DC 18. They can repeat the saving throw once every 10 minutes to end the effect early. 10/20/40 GP
