Binder Amulet

Wondrous item, rarity varies (see text)

A binder amulet consists of a small glass egg on a silver chain with a gemstone embedded within it.

Once per long rest, the holder of a binder amulet can use an action to speak the amulet’s command word and summon a fey creature as if casting the conjure fey spell. However, if the user loses concentration during the spell and frees the fey, the amulet shatters and its magic is permanently lost.

Each binder amulet allows you to summon one type of fey creature. The type of fey is determined by the gemstone the amulet contains.

Gemstone	Type of Fey	Rarity
Spinel	Blink Dog	Uncommon
Red Onyx	Satyr	Uncommon
Amber	Dryad	Rare
Emerald	Sprite	Rare
Ruby	Pixie	Rare
Black Sapphire	Night Hag	Very Rare
