Bapar Ghalmrin's Imperishable Ark (Chest of Preserving)
Food and other perishable items do not age or decay while inside a Chest of Preserving. The chest is 2½ feet long, 1½ feet wide, and 1 foot tall with a half-barrel lid. The chest has a lock, which can be picked with thieves' tools and a successful DC 15 Dexterity check. Smashing the lock or any other part of the chest renders it nonmagical.

This copper-plated chest has gold stripes and a magical painting of dwarves feasting in a hall. When the chest is empty of food, the dwarves look sad. When the chest is full of food, the dwarves smile happily. Interestingly, this chest never gets dirty.

Wondrous Item, uncommon While wearing this cap underwater, you can speak its command word as an action to create a bubble of air around your head. It allows you to breathe normally underwater. This bubble stays with you until you speak the command word again, the cap is removed, or you are no longer underwater.

Wondrous Item, very rare
You can speak the carpet's command word as an action to make the carpet hover and fly. It moves according to your spoken directions, provided that you are within 30 feet of it.

Four sizes of carpet of flying exist. The DM chooses the size of a given carpet or determines it randomly.

Size Capacity Flying Speed
3 ft. x 5 ft. 200 lb. 80 feet
4 ft. x 6 ft. 400 lb. 60 feet
5 ft. x 7 ft. 600 lb. 40 feet
6 ft. x 9 ft. 800 lb. 30 feet

A carpet can carry up to twice the weight shown on the table, but it flies at half speed if it carries more than its normal capacity.

Wondrous Item, common
This common wondrous item has the following magical property: food and other perishable items do not age or decay while inside it. The chest is 2½ feet long, 1½ feet wide, and 1 foot tall with a half-barrel lid. It weighs 25 pounds.

Wondrous Item, rare
This hollow metal tube measures about 1 foot long and
weighs 1 pound. You can strike it as an action, pointing
it at an object within 120 feet of you that can be opened,
such as a door, lid, or lock. The chime issues a clear tone,
and one lock or latch on the object opens unless the
sound can't reach the object. If no locks or latches
remain, the object itself opens.
The chime can be used ten times. After the tenth time, it
cracks and becomes useless.

Armor (plate), very rare (requires attunement)
While wearing this armor, you gain a +1 bonus to AC, and you can understand and speak Abyssal. In addition, the armor’s clawed gauntlets turn unarmed strikes with your hands into magic weapons that deal slashing damage, with a +1 bonus to attack rolls and damage rolls and a damage die of 1d8.

Curse. Once you don this cursed armor, you can’t doff it unless you are targeted by the remove curse spell or similar magic. While wearing the armor, you have disadvantage on attack rolls against demons and on saving throws against their spells and special abilities.

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.

Elminster’s Hat of Wizardry
Wondrous Item, Common (Requires Attunement by a Wizard)

This antiquated, cone-shaped hat is adorned with gold crescent moons and stars. While you are wearing it, you gain the following benefits:

· You can use the hat as a spellcasting focus for your wizard spells.

· You can try to cast a cantrip that you don’t know. The cantrip must be on the wizard spell list, and you must make a DC 10 Intelligence (Arcana) check. If the check succeeds, you cast the spell. If the check fails, so does the spell, and the action used to cast the spell is wasted. In either case, you can’t use this property again until you finish a long rest.

This item is found in Xanathar's Guide to Everything, pg. 137.

This red conical hat is very worn.

This bright plume is made from the feather of a diatryma (pronounced dee-ah-TRY-mah), a Large, colorful, flightless bird native to the Underdark. If you use an action to speak the command word and throw the feather into a Large unoccupied space on the ground within 5 feet of you, the feather becomes a living diatryma for up to 6 hours, after which it reverts to its feather form. It reverts to feather form early if it drops to 0 hit points or if you use an action to speak the command word again while touching the bird.

When the diatryma reverts to feather form, the magic of the feather can’t be used again until 7 days have passed.

The diatryma uses the statistics of an axe beak, except that its beak deals piercing damage instead of slashing damage. The creature is friendly to you and your companions, and it can be used as a mount. It understands your languages and obeys your spoken commands. If you issue no commands, the diatryma defends itself but takes no other actions.

You have +1 to your AC while wearing this Armor.

Wondrous Item, varies
You can use an action to blow this horn. In response, warrior spirits from the Valhalla appear within 60 feet of you. They use the statistics of a berserker. They return to Valhalla after 1 hour or when they drop to 0 hit points. Once you use the horn, it can't be used again until 7 days have passed.

Four types of horn of Valhalla are known to exist, each made of a different metal. The horn's type determines how many berserkers answer its summons, as well as the requirement for its use. The GM chooses the horn's type or determines it randomly.

d100 Horn Type Berserkers Summoned Requirement
01-40 Silver 2d4 + 2 None
41-75 Brass 3d4 + 3 Proficiency with all simple weapons
76-90 Bronze 4d4 + 4 Proficiency with all medium armor
91-100 Iron 5d4 + 5 Proficiency with all martial weapons
If you blow the horn without meeting its requirement, the summoned berserkers attack you. If you meet the requirement, they are friendly to you and your companions and follow your commands.

Wondrous item, very rare (requires attunement)

An Ioun stone is named after Ioun, a god of knowledge and prophecy revered on some worlds. Many types of Ioun stone exist, each type a distinct combination of shape and color.

When you use an action to toss one of these stones into the air, the stone orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an action to grasp or net the stone to separate it from you, either by making a successful attack roll against AC 24 or a successful DC 24 Dexterity (Acrobatics) check. You can use an action to seize and stow the stone, ending its effect.

A stone has AC 24, 10 hit points, and resistance to all damage. It is considered to be an object that is being worn while it orbits your head.

Your Constitution score increases by 2, to a maximum of 20, while this pink rhomboid orbits your head.
