Vaporizer

The companion piece to the volumizer, and easily confused with it. Where a volumizer makes a second potion, this one makes the single potion go further: broken open, it releases the draught as a cloud of gas about five feet across, and everybody standing in it breathes the full effect rather than a share of it. It will not do this for every potion, but it will for most.

One came out of the alchemist’s belt in the keep, alongside the rest.

It has never been used: not on either entry into the keep, and not in the kit the party carried into the last fight.
