Air coin

This Clear glass coin is embossed with the primordial rune for air. The first time you hold this coin and squeeze it in your hand it burns the symbol into your palm. This coin holds three charges that regenerate 1d3 at dawn. You can expend up to 3 charges as a bonus action to move with the speed of the wind for one round. 

1 charge: add 5 feet to your speed 

2 charges: add 10 feet to your speed 

3 charges: add 15 feet to your speed

While this coin is on your person you may spend 1 charge to make your body appear as if it were made of shifting wind, granting you advantage on any charisma checks to interact with creatures from the elemental plane of air for 1 hour.
