Amulet of Forgetfulness

This amulet is carved from obsidian and shaped like a screaming humanoid skull, with ruby eyes and emeralds for teeth. It hangs from an iron chain necklace.

While wearing the amulet, you can use an action to name a place you are familiar with to transport yourself and anything you are wearing or carrying to another plane of existence or move to a place 100 feet from you. The destination you choose doesn’t need to be in your line of sight, but it must be familiar to you (in other words, a place you have seen, visIted, or know very well).

This amulet is fueled by your memories and the memories of you. If you cannot supply the amulet with your own memories, a memory of you will taken from those who know of you. You then must make a DC 25 Intelligence saving throw to use the amulet to teleport. On a failed saving throw, the skull cackles as you have a random occurrence happen to you in transit. The occurrence takes effect as soon as you arrive at the destination, and is determined randomly by rolling percentile dice and consulting the Forgetfulness Occurrences table.
