Potion Compounder

Wondrous item, uncommon

This contraption looks like a cork for a potion bottle with two funnels coming out the top leading into a spiral of tubes out the bottom. When you pour two different potions into the funnels—one potion per funnel—the potions spend 1 hour mixing inside the compounder before coming out the other end as one potion with the effects of both original potions. There is no effect if you pour two of the same potion into the funnels or if you pour multiple potions into one funnel. If you pour additional potions into the compounder while it is mixing two potions already, the additional potions are lost.

If the compounder attempts to mix a potion made by a compounder with another potion, the compounder explodes, destroying it and the added potions. Each creature in a 15-foot-radius sphere centered on the compounder makes a DC 14 Dexterity saving throw, taking 4d6 fire damage and 2d6 piercing damage on a failed save or half as much damage on a successful one.
