This coin is inhabited by the spirit of a friendly Air Elemental keen to escape from the domains of dread. By attuning to it, it will lend you some of its power to help you deal with the horrors of the realm. The elemental can communicate emotions and images to you telepathically but cannot speak. 

The elemental has three charges of power it can provide, and recharges every dawn. You can expend one charge to trigger any of the following three effects:

• As a reaction when you are hit by an enemy's attack, you can increase your AC by 5 temporarily, potentially causing the attack to miss.
• As a reaction, when you are forced to make a Saving Roll against a physical effect, you can roll at advantage.
• As a bonus action, you can Increase walking speed by 15 feet for 1 minute.
