Ba'al Verzi Magic Mirror

From Curse of Strahd, this magic mirror summons the spirit of a namless Ba'al Verzi] assassin when the right rhyme is said. The spirit will only manifest as an assassin if the summoner is not Evil, otherwise, the spirit manifests as a ghost that attempts to kill the (Evil) summoner. The problem is that using the item can be highly corrupting for non-Evil characters, as each time there is a significant chance the user will turn Evil. Depending upon how characters might interact with it, it may get Strahd's attention and let his reflection appear in the mirror.

Location

The Mmirror is held in Area N3P of the Burgomaster's Mansion (Vallaki)
