Bubbles of Oblivion

This glass bottle in the size of an adult's hand houses a purplish mixture resembling a potion. However this is no potion at all. In the bottle's cap is attached a wand-like stick that its end is ring-like. In other words, this is a bubble blower.

A bubble of this mixture blown from the blower is no mere soap, but a concoction that causes a humanoid touched by a single bubble to lose the last minutes of their memory.

This magic bubble blower and mixture was created by a wizard-thief during a time before the Scarring. The purpose of its creation was to make his heists easier as he would blow a bubble to someone that detected him, erase the last five minutes of memories of those that caught him in the act, and he would then make his escape.

It has since been used by some thieves' guilds should they manage to get their hands on one.

Wondrous Item (Rare)

You can blow a bubble using this item as an action. If a bubble blown by this item touches a humanoid, it can delete the last five minutes of memory of that humanoid. For that to happen the target must fail a DC 15 Wisdom Saving Throw. Should the same person be touched by a bubble again they regain their lost memory of the five minute lapse. A bubble cannot pass through an Antimagic Field or through effects similar to it. It has a range of 15 feet.

This bottle's mixture has a number of uses equal to 1d8 + 3.
