Adamantine Bands of Warding

These thick adamantine bands are designed to cover the wrists. Each band has a diamond shaped crystal embedded into its surface surrounded by six unique sigils. When the crystal is shifted so it points to one of these sigils, it changes color to match the color of the sigil, and the bands emit an aura of similarly colored energy around your entire body.

While wearing these bands, choose between Strength, Dexterity, Constitution, Intelligence, Wisdom, or Charisma each dawn. You take no damage when you succeed on the selected type of saving throw, and only take half damage when you fail on the selected type of saving throw. As an action on your turn, you may change the type of saving throw you currently have selected. When you do so, roll a d20. On a 1, the bands overheat and lose their properties for the next 6 days. The DC for overheating increases by 1 each time you use this action before the next dawn. Should the DC ever reach 15 or higher and fail, they are destroyed and reduced to ash.
