My brother had a fun idea for our Pathfinder game. Let’s being it here!
Confusion Potion: This purple liquid can be absorbed either internally or via the skin. You can slip this into a targets food or attack with it. As an action, you can throw this flask up to 20 feet, shattering it on impact. Make a ranged attack against a creature, treating the confusion potion as an improvised weapon. On a hit or ingestion, the target must make a DC 13 Wisdom saving throw or be affected by the confusion spell for one round. Targets immune to confusion are immune to this potion.
Cost: 50 gp
