Portable Hole

wondrous item, rare

Details:

Dry, blisteringly hot air carrying embers and ashes blows from within the portable hole whenever it’s opened.

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.

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, Heward's 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.

Tentacle Rod
DMG
p208
Rod, rare (requires attunement)
Major tier
2 lb.
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.

staff, weapon, rare (requires attunement), simple weapon, melee weapon,

Value/Weight: 3 lb.

Details: 1d6 bludgeoning - versatile (1d8)

This slender, hollow staff is made of a translucent green glass yet is as strong as oak. It weighs 3 pounds. You must be attuned to the staff to gain its benefits and cast its spells.

While holding the staff, you have a +1 bonus to your Armor Class.

The staff has 10 charges, which are used to fuel the spells within it. With the staff in hand, you can use your action to cast one of the following spells from the staff if the spell is on your class's spell list: mage armor (1 charge) or shield (2 charges). No components are required.

The staff regains 1d6 + 4 expended charges each day at dawn. If you expend the staff's last charge, roll a d20. On a 1, the staff shatters and is destroyed.

Versatile.
This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.

wondrous item, minor tier, common

Value/Weight:

Details:

A miniature mechanical dragonborn wielding a two-handed sword encrusted with small garnets is nestled in the center of an intricate bronze sphere hanging from a translucent green chain. Pressing a button causes the mechanical warrior to go through an elaborate series of thrusts and parries within the confines of the sphere.
When you make an attack roll while wearing the amulet, you can forgo rolling the d20 to get a 10 on the die. Once used, this property can’t be used again until the next dawn.

This “rope” consists of 50 feet of lightning that functions as a standard rope despite its “shocking” appearance.
