Potion uncommon
This typical and non-descript bottle contains a liquid that is similar but different from water. The potion has an unusual, but difficult to describe, taste. When you drink this potion, you do not appear any different from normal. However, anyone who encounters you will not be able to remember details about your appearance or personality. Additionally, any creature attempting to recall any memories about those encounters will only remember vague, indistinguishable details that are hard to explain to others. The effects of this elixir last 24 hours or until you speak your true name.
