Angelus

By sacrificing any amount of bones to the great axolotl. Then sprout two wings made of bone from your shoulder blades. The wings will increase your AC by 10 for each extra bone sacrificed and will grow in size by 3 ft for each bone sacrificed but the user will not be able move by their self for the duration that said wings are active. The wings will disappear once dismissed or broken by 25 bludgeoning damage or more. Alternatively you can sacrifice a willing persons bones to create these wings but if the donor dies the wings disappear. To cure the price you must take 1 long rest and be healed by 3rd level healing magic or more.
