Magic Items

Wondrous item, legendary (requires attunement)
This lavender and green stone has been fashioned into the shape of a strange dragon; it has a long, sinewy neck, a body like a serpent, four stout legs, and two long whiskers that almost look like a mustache.
This is what the dragons of far-off Shou Lung in Kara-Tur look like.
While this marbled object orbits your head, you can use your reaction to cancel a spell of 8th level or lower cast by a creature you can see and targeting only you. Once the stone has canceled 50 levels of spells, it burns out and turns dull gray, losing its magic. If you are targeted by a spell whose level is higher than the number of spell levels the stone has left, the stone can't cancel it.
This item is found on Magic Item Table I in the Dungeon Master’s Guide.

Wondrous item, legendary
While not a truly intelligent item, the Eye of Xxiphu bestows terrifying insight into the true nature of the nightmarish aboleths. The attuned possessor of the Eye gains telepathy out to a range of 120 feet, and may cover themselves in coat of mucous that allows them to breathe underwater as well as on land. The petrified orb is large and heavy, but does not need to be held in order to use its powers. Additionally, aboleths have disadvantage when attacking the owner of the Eye, and the owner has advantage on ability checks in regards to knowledge-based ability checks about aboleths and the Far Realm when they are not in combat.

This tattered mantle of gossamer white silk once adorned the shoulders of The Simbul’s vengeful simulacrum. An echo of the construct’s animating force has suffused the fabric, causing the hem of the garment to glow with a faint, silvery sheen.
