Amulet of Cloaking Shadows.

This amulet is made of twigs and vines woven around an un-worked chunk of obsidian and darkly lacquered. The amulet has 15 charges and regains 1d8+7 charges each dawn. As an action 1 charge may be spent to cast the longstrider spell, 2 charges may be spent to cast the pass without trace spell and 6 charges may be used to cast the tree stride spell. The amulet also provides the wearer advantage on all stealth checks and allows them to attempt to hide when only lightly obscured.
