Necklace of Favors
This necklaces bears a number stone charms on it, each the size of a coin and etched with a rune. As a bonus action on your turn, you can remove the charm from the necklace to immediately gain its effect.
Charm of Flight. You gain the effect of the fly spell.
Charm of Providence. You gain the effect of the divine favor spell.
Charm of Recovery. You gain the effect of the cure wounds spell (3rd level version)
Charm of Safe Landings. You gain the effect of the feather fall spell.
Charm of Secrets. A rope trick spell takes effect within 20 feet of you.
Charm of Servitude. An unseen servant spell takes effect within 20 feet of you.
Because you gain the effect of the spell, without actually casting it, you do not need to concentrate to maintain the effect. However, multiple uses of the same charm have no effect while another instance of the charm is active. Once the last charm has been removed, the necklace loses its magical power and becomes a mundane piece of jewelry.
