Magic Items

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.

Ring of Fire Resistance
Ring, Major, Rare (Requires Attunement)
Table G, Tier 2-4, 20 TCP
You have resistance to fire damage while wearing this ring.

This simple ring of twisted brass wire is warm to the touch.

Wondrous item, rare, Table D

• This fine black cloth, soft as silk, is folded up to the dimensions of a handkerchief. It unfolds into a circular sheet 6 feet in diameter. Any creature inside of the hole hears a slight slurping sound in the distance; the sound can never be located.
• You can use an action to unfold a portable hole and place it on or against a solid surface, whereupon the portable hole creates an extradimensional hole 10 feet deep. The cylindrical space within the hole exists on a different plane, so it can't be used to create open passages. Any creature inside an open portable hole can exit the hole by climbing out of it.
• You can use an action to close a portable hole by taking hold of the edges of the cloth and folding it up. Folding the cloth closes the hole, and any creatures or objects within remain in the extradimensional space. No matter what's in it, the hole weighs next to nothing.
• If the hole is folded up, a creature within the hole's extradimensional space can use an action to make a DC 10 Strength check. On a successful check, the creature forces its way out and appears within 5 feet of the portable hole or the creature carrying it. A breathing creature within a closed portable hole can survive for up to 10 minutes, after which time it begins to suffocate.
• Placing a portable hole inside an extradimensional space created by a Bag of Holding, Handy Haversack, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it and deposited in a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened. This item is found in the Dungeon Master’s Guide.

Wondrous item, rare

This rusty iron sphere measures 3 inches in diameter and weighs 1 pound. You can use an action to speak the command word and throw the sphere at a Huge or smaller creature you can see within 60 feet of you. As the sphere moves through the air, it opens into a tangle of metal bands.

Make a ranged attack roll with an attack bonus equal to your Dexterity modifier plus your proficiency bonus. On a hit, the target is restrained until you take a bonus action to speak the command word again to release it. Doing so, or missing with the attack, causes the bands to contract and become a sphere once more.

A creature, including the one restrained, can use an action to make a DC 20 Strength check to break the iron bands. On a success, the item is destroyed, and the restrained creature is freed. If the check fails, any further attempts made by that creature automatically fail until 24 hours have elapsed.

Once the bands are used, they can’t be used again until the next dawn.

Flame Tongue Long Sword
Weapon, rare (requires attunement)

This longsword is crafted of mithril with a beautiful hilt of carved ironwood. The crossguard, blade, and hilt are worked through with a forest motif inlaid with shining emeralds and platinum filigree. Delicate blue flames dance along the blade whenever it is drawn from its scabbard.

You can use a bonus action to speak this magic sword's command word, causing flames to erupt from the blade. These flames shed bright light in a 40-foot radius and dim light for an additional 40 feet. While the sword is ablaze, it deals an extra 2d6 fire damage to any target it hits. The flames last until you use a bonus action to speak the command word again or until you drop or sheathe the sword.

Death's Head (Mace of Disruption)
Weapon (mace), rare (requires attunement), Table G
This magical mace has a long, stout handle wrapped in black leather. The top is an ornately carved skull, its mouth opened as if screaming. Curved ram-like horns protrude from temples of the skull. When it strikes an undead or fiendish foe, golden sparks, tinged with flame burst forth, and the mace rings forth a single ominous toll, as if from a large bell.
When you hit a fiend or an undead with this magic weapon, that creature takes an extra 2d6 radiant damage. If the target has 25 hit points or fewer after taking this damage, it must succeed on a DC 15 Wisdom saving throw or be destroyed. On a successful save, the creature becomes frightened of you until the end of your next turn.
While you hold this weapon, it sheds bright light in a 20-foot radius and dim light for an additional 20 feet.
Special. This item has the harmonious minor property. Attuning to it takes only 1 minute.
This item can be found in the Dungeon Master's Guide.

Censer of Controlling Air Elementals
Wondrous item, rare

While incense is burning in this censer, you can use an action to speak the censer’s command word and summon an air elemental, as if you had cast the conjure elemental spell. The censer can’t be used this way again until the next dawn.

This 6-inch-wide, 1-foot-high vessel resembles a chalice with a decorated lid. It weighs 1 pound.
