"You can't get hit if you were never there"
This fine metal shield glows faintly blue when touched. Striking it produces a flash of light.
When you are hit with a weapon or spell attack while wielding this shield, you can use a reaction to activate this magic item. When you do so, you take no damage from the attack, and you disappear in a flash of light, only to reappear at the start of your next turn. While you have disappeared you are incapacitated but cannot be targeted or take damage from any source. The shield can't be used this way again until the next dawn.
Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
Notes: Immunity: All, Incapacitated, Combat, Warding
