Runescribe Robe

Wondrous item (raiment), rare (requires attunement)

This robe is made from heavy grey cloth. It is embroidered with elaborate runewords of metallic thread all over, granting its wearer a measure of protection against magical energy. While attuned to this item, you have resistance to damage from spells. Additionally, the wearer can choose to automatically succeed on saving throws from spells cast by themselves, and they take no damage on a successful save.
