The Thirteenth Throne
This undershirt is made from the finest of Thurian thread. It's been mended many times.
When you cast a spell that targets yourself, you also charge this shirt with that spell. When it’s charged, you can ativate it as a free action to gain the benefits of that spell for one round. It has to be an ongoign spell – Dimension Door or Teleport are instant, and aren’t good targets. Blur works, but Lightning Bolt doesn’t.
The shirt’s appearance changes to reflect the stored spell. Feather fall makes it puffy and silky. Water Breathing is green and clings to your skin.
QUIRK: Wearer is compelled to change hairstyle and wardrobe to complement the shirt.
