Wondrous item, common (requires attunement)
An orb of shielding is a polished, spherical chunk of crystal or stone aligned to one of the planes of existence. If you're a spellcaster, you can use this orb as a spellcasting focus.
If you're holding the orb when you take damage of the type associated with the orb's material, you can use your reaction to reduce the damage by 1d4 (to a minimum of 0). The materials and their associated damage types are listed in the Orb of Shielding table.
