Xerxes' War Magus Cloak

{w} This cloak is woven with magical energy. Whilst attuned to an Eldritch Knight, it constantly flutters as though wind was blowing. Additionally, whenever you use your War Magic feature after you successfully deal damage with a cantrip your weapon deals an additional 2d6 Force damage on hit.
The warmth around your shoulders reminds you of whence you came. The glow of the stars, and of her smile. You know where you must go now.
