Feather Token

From Eberron: Rising From the Last War, page 277; and Wayfinder's Guide to Eberron, page 115.

Description
Wondrous item, common.

This small metal disk is inscribed with the image of a feather. When you fall at least 20 feet while the token is on your person, you descend 60 feet per round and take no damage from falling. The token's magic is expended after you land, whereupon the disk becomes nonmagical.

This small metal disk is inscribed with the image of a feather. While the token is in your possession, you can cast Feather Fall as a bonus action. A feather token only holds sufficient charge for a single use, after which it loses its power. While it's an expensive form of insurance, frequent airship travelers and citizens of Sharn often appreciate the security it provides.
