Magic items (5E)

Daern’s instant fortress

Wondrous item, rare

You can use an action to place this 1-inch metal cube on the ground and speak its command word. The cube rapidly grows into a fortress that remains until you use an action to speak the command word that dismisses it. which works only if the fortress is empty.

The fortress is a square tower, 20 feet on a side and 30 feet high, with arrow slits on all sides and a battlement atop it. Its interior is divided into two floors. with a ladder running along one wall to connect them. The ladder ends at a trapdoor leading to the roof. When activated, the tower has a small door on the side facing you. The door opens only at your command, which you can speak as a bonus action. It is immune to the knock spell and similar magic, such as that of a chime of opening.

Each creature in the area where the fortress appears must make a DC 15 Dexterity saving throw, taking 10d10 bludgeoning damage on a failed save, or half as much damage on a successful one. In either case, the creature is pushed to an unoccupied space outside but next to the fortress. Objects in the area that aren’t being worn or carried take this damage and are pushed automatically.

The tower is made of adamantine, and its magic prevents it from being tipped over. The roof, the door, and the walls each have 100 hit points, immunity to damage from nonmagical weapons excluding siege weapons, and resistance to all other damage. Only a wish spell can repair the fortress (this use of the spell counts as replicating a spell of 8th level or lower). Each casting of wish causes the roof, the door, or one wall to regain 50 hit points.

Heward’s handy haversack

Wondrous item, rare

This backpack has a central pouch and two side pouches, each of which is an extradimensional space. Each side pouch can hold up to 20 pounds of material, not exceeding a volume of 2 cubic feet. The large central pouch can hold up to 8 cubic feet or 80 pounds of material. The backpack always weighs 5 pounds, regardless of its contents.

Placing an object in the haversack follows the normal rules for interacting with objects. Retrieving an item from the haversack requires you to use an action. When you reach into the haversack for a specific item, the item is always magically on top.

The haversack has a few limitations. If it is overloaded, or if a sharp object pierces it or tears it, the haversack ruptures and is destroyed. If the haversack is destroyed, its contents are lost forever, although an artifact always turns up again somewhere. If the haversack is turned inside out, its contents spill forth, unharmed, and the haversack must be put right before it can be used again. If a breathing creature is placed within the haversack, the creature can survive for up to 10 minutes, after which time it begins to suffocate.

Placing the haversack inside an extradimensional space created by a bag of holding, 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 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.

Quiver of Ehlonna

Wondrous item, uncommon

Each of the quiver’s three compartments connects to an extradimensional space that allows the quiver to hold numerous items while never weighing more than 2 pounds. The shortest compartment can hold up to sixty arrows, bolts, or similar objects. The midsize compartment holds up to eighteen javelins or similar objects. The longest compartment holds up to six long objects, such as bows, quarterstaffs, or spears.

You can draw any item the quiver contains as if doing so from a regular quiver or scabbard.
