Magic Items

Wondrous item (requires attunement),

This helm of telepathy takes the form of bejeweled tiara sporting a tiger’s eye stone and the heraldry of the Dukes of Scelptar. When worn, you feel an affection for house cats.
While wearing this helm, you can use an action to cast the detect thoughts spell (save DC 13) from it. As long as you maintain concentration on the spell, you can use a bonus action to send a telepathic message to a creature you are focused on. It can reply-using a bonus action to do so-while your focus on it continues. While focusing on a creature with detect thoughts, you can use an action to cast the suggestion spell (save DC 13) from the helm on that creature. Once used, the suggestion property can't be used again until the next dawn.
This item can be found in the Dungeon Master’s Guide.

Rod

This flat iron rod has a button on one end. You can use an action to press the button, which causes the rod to become magically fixed in place. Until you or another creature uses an action to push the button again, the rod doesn't move, even if it is defying gravity. The rod can hold up to 8,000 pounds of weight. More weight causes the rod to deactivate and fall. A creature can use an action to make a DC 30 Strength check, moving the fixed rod up to 10 feet on a success.

Wondrous item,

A red leather bag.

This bag has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. The bag can hold up to 500 pounds, not exceeding a volume of 64 cubic feet. The bag weighs 15 pounds, regardless of its contents. Retrieving an item from the bag requires an action.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.

Placing a bag of holding inside an extradimensional space created by a handy haversack, portable hole, 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 to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.

Heavy armor, minor tier, 65 lb. AC 18 Mithral is a light, flexible metal. A mithral chain shirt or breastplate can be worn under normal clothes. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn't. Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.

Wondrous item (requires attunement by an artificer) This simple screwdriver can transform into a variety of tools; as an action, you can touch the item and transform it into any type of artisan's tool of your choice (see the "Equipment" chapter in the Player's Handbook for a list of artisan's tools). Whatever form the tool takes, you are proficient with it. While holding this tool, you gain a +1 bonus to the spell attack rolls and the saving throw DCs of your artificer spells. As an action, you can focus on the tool to channel your creative forces. Choose a cantrip that you don't know from any class list. For 8 hours, you can cast that cantrip, and it counts as an artificer cantrip for you. Once this property is used, it can't be used again until the next dawn. Additional Minor Property: Since this tool has been carved out of the Treant Key Duot'ho's own wood, it is infused with a glimpse of his power (his voice): War Leader. The bearer can use an action to cause his or her voice to carry clearly for up to 300 feet until the end of the bearer's next turn.

Ring, (requires attunement),

This ring holds a red crystal set in a silver band carved to look like a ring of flames. It was formed from the Heart of the Tower after your adventures in the village of Rymdyl.

The life and magic of mage and a fire elemental have formed this item.

You have fire resistance while wearing this ring. In addition, it has the Temperate minor property, which means you suffer no harm from temperatures as cold as -20 degrees Fahrenheit or as warm as 120 degrees Fahrenheit while it is equipped.

This item can be found on page 192 of the Dungeon Master's Guide.
