Amulet of the Many Forms

Trinket

This artifact can only be worn by a druid.

When the druid wearing the artifact takes on a wild shape, the artifact will store that wild shape in it and its form will change to reflect it.

Once the artificact has stored a wild shape, a druid can use a bonus action to invoke the form stored in the artifact and assume the stored wild form, once per day. Once used in such a manner, the artifact loses its stored form and cannot absorb another for 1 day.

If the druid, after invoking the stored wild shape, suffers enough damage that will force them to lose their wild shape, the artifact shatters and it's lost forever.
