Magic Items

Ring of Telekinesis
Ring, very rare (requires attunement)

While wearing this ring, you can cast the telekinesis spell at will, but you can target only objects that aren’t being worn or carried.

Ring of X-ray Vision

Ring, rare (requires attunement)

This ring bears a topaz in the shape of a jack-o’-lantern. Its command word is “pumpkin.”

While wearing this ring, you can use an action to speak its command word. When you do so, you can see into and through solid matter for 1 minute. This vision has a radius of 30 feet. To you, solid objects within that radius appear transparent and don’t prevent light from passing through them. The vision can penetrate 1 foot of stone, 1 inch of common metal, or up to 3 feet of wood or dirt. Thicker substances block the vision, as does a thin sheet of lead.

Whenever you use the ring again before taking a long rest, you must succeed on a DC 15 Constitution saving throw or gain 1 level of exhaustion.

Serpent Scale Armor
Armor (scale mail), uncommon

This suit of magic armor is made from shimmering scales. While wearing it, you can apply your full Dexterity modifier (instead of a maximum of +2) when determining your Armor Class. In addition, this armor does not impose disadvantage on your Dexterity (Stealth) checks.

Serpent's Fang
Weapon (longsword), rare

This single-edged magic sword is made from the scrimshawed fang of a giant serpent. Its hilt changes shape to adjust to the grasp of any creature that picks it up. The weapon deals an extra 1d10 poison damage to any target it hits.

Tentacle Rod
Rod, rare (requires attunement), Table G
Made by the drow, this rod is a magic weapon that ends in three rubbery tentacles. While holding the rod, you can use an action to direct each tentacle to attack a creature you can see within 15 feet of you. Each tentacle makes a melee attack roll with a +9 bonus. On a hit, the tentacle deals 1d6 bludgeoning damage. If you hit a target with all three tentacles, it must make a DC 15 Constitution saving throw. On a failure, the creature's speed is halved, it has disadvantage on Dexterity saving throws, and it can't use reactions for 1 minute. Moreover, on each of its turns, it can take either an action or a bonus action, but not both. At the end of each of its turns, it can repeat the saving throw, ending the effect on itself on a success.
This item can be found on page 208 of the Dungeon Master's Guide.

The Sixth Sword (+2 Rapier with Guardian minor property)

Weapon, rare, Table G

This is one of marilith S’Sheneth’Rah’s six swords. In battle she was known for her tactical superiority and quick striking. Through years of use, some of her essence became imbued into the sword’s magic and it occasionally twitches at critical times, bringing itself to a ready and deadly position. As a result of this, the wielder gains a +2 bonus to initiative.
