When a person drinks a draft from this flask, the user can immediately trade positions with any one creature of similar size within the drinker’s line of sight. Thus a human could only swap places with another medium sized creature and a halfling only with another small creature. If the other subject is unwilling, the drinker must beat the target in an opposed Charisma check. If the target succeeds, the draft has no effect.

If left empty, the flask automatically refills with a single draft every night at midnight. The flask can hold a maximum of 4 drafts. If filled with any other liquid, the flask will permanently lose all magical properties.
