Blessing of the Flametouched

A shulassakar who has been chosen by the power of the Silver Flame may be reborn into greater power, either through a cycle of death and rebirth or through the attentions of divine power, gaining a changed physical form and the ability to channel the power of the Flame into themselves temporarily.
As a flametouched, you have iridescent, feathered wings of shifting colours that emerge from your back. They grant you a fly speed equal to your walking speed while extended, and can be folded down to press close against the back, their shape becoming difficult to spot. Your appearance also changes to include feathers and more scaled patterns at your discretion.
As a bonus action, you can invoke the power of the Flame, suffusing yourself with divine power for the next minute. During this time you gain the following benefits:

• Your melee attacks deal an additional 1d6 radiant damage, and you may choose to have them deal radiant damage instead of any other damage type.
• You gain resistance to fire and radiant damage
• You can hover in place, and stopping your movement or being knocked prone does not cause you to fall automatically.
• Once during the blessing's duration, you may cast either flame strike, mass cure wounds, or planar binding, ignoring material components, and using Wisdom as your spellcasting modifier.

After the blessing ends, you immediately gain one level of exhaustion, and cannot invoke the blessing again until you have completed a long rest.
