Tempest's Wing Ethereal Cloak

This shimmering cloak appears to shift colors, predominantly featuring deep azure and shadowy hues. While wearing the Tempest's Wing Ethereal Cloak, you gain a flying speed of 30 feet. Additionally, you can cast the spell 'Fog Cloud' once per long rest without expending a spell slot. If you take damage while flying, you can use your reaction to teleport to a space you can see within 30 feet of your original location, disappearing in a swirl of mist as you leave behind a gust of wind that pushes away small objects and creatures in a 5-foot radius (they must make a DC 13 Strength saving throw or be knocked prone). This cloak is a favored accessory among the fiendish denizens of the Tempest Plains, granting its wearer an ethereal presence and a taste of their stormy fury.
