Orb of Shielding (Xorian Marble)

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 psychic damage, you can use your reaction to reduce the damage by dice:1d4|noform|noparens|avg (1d4) (to a minimum of 0).
