Awakened Platinum North Wind Seal

When you hit anything solid with the moonblade or an arrow from the bow mode you leave a small, invisible seal in the shape of Bahamut's sigil on wherever it hits. This seal stays forever with no consequence to where it is placed and cannot be dismissed save for a member of Bahamut's family. The seal is undetectable by any sort of magic and can only be detected by Tiamat, Io or a wish spell. By using a bonus action you can teleport to any seal you have placed.
