Goblet of the Great Kingdom

This magic goblet was commissioned on order of nobles of the Great Kingdom of Aerdy who had good reason to fear assassination. This magic goblet appears to be a normal drinking vessel made of polished oak. However, when you store a liquid within it, you can use a Magic Action to neutralize any poison or venom within the liquid. Once you use this property three times, you can't use it again until you finish a Long Rest.
