Alchemicowl

Alchemists have toiled for years to extend the duration of their potions through additives  and alternative brewing processes until an artificer postulated that the delivery method could be improved.  By aerosolizing potions to be inhalable instead of imbibing them, it was found that they could be much improved.

While wearing this cowl, you can use an action to slot-in or replace a potion bottle into one of its two valves. While at least one potion is inserted, you can use a bonus action on your turn to aerosolize one or both of the slotted potions.  If a potion has a duration, its duration is doubled. If the potion does not have a duration, then it is instantly applied.
