Flumfpot

Wondrous item, rare
  Flumfpots are always found hovering around a corpse. If you can’t see the corpse then it’s almost definitely because it’s been so long the corpse has disintegrated into dust. This is because a flumfpot is magically enchanted to always follow the last creature whose lips (or other drinking orifice) it touched. It can be filled with any potion as an action.
  Mastery and Movement. After touching a creature’s lips that creature becomes its master. It hovers just over its master’s shoulder. It has a flying speed of 30 feet and a swimming speed of 60 feet.
  If it is within 5 feet of its master when its master teleports, it teleports with them, even teleporting between planes. Otherwise it remains in palace until touched by another creature’s lips. A flumfpot that is restrained for whatever reason will fly towards its master via the most direct route when released.
  Send Aid. As a bonus action you can send the flumfpot to help a creature you can see. The flumfpot shares your initiative count, but it takes its turn immediately after yours. It moves up to its speed towards the designated target. If it ends its turn in the target’s space and the target is willing or unconscious, it administers the potion to the target.
  Filling Flumfpot. A flumfpot magically refills with the same potion each day at dawn. When you find a flumfpot, roll a d20 and consult the following table to determine the potion.
