Wondrous Item, Rare (Requires Attunement)
As a Magic action, you can place this 1-inch adamantine statuette on the ground and, using a command word, cause it to grow rapidly into a square adamantine tower. Repeating the command word causes the tower to revert to statuette form, which works only if the tower is empty. Each creature in the area where the tower appears is pushed to an unoccupied space outside but next to the tower. Objects in the area that aren’t being worn or carried are also pushed clear of the tower.
The tower is 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, staircase, or ramp (your choice) connecting them. This ladder, staircase, or ramp ends at a trapdoor leading to the roof. When created, the tower has a single door at ground level on the side facing you. The door opens only at your command, which you can issue as a Bonus Action. It is immune to the Knock spell and similar magic.
Magic prevents the tower from being tipped over. The roof, the door, and the walls each have AC 20; HP 100; Immunity to Bludgeoning, Piercing, and Slashing damage except that which is dealt by siege equipment; and Resistance to all other damage. Shrinking the tower back down to statuette form doesn’t repair damage to the tower. Only a Wish spell can repair the tower (this use of the spell counts as replicating a spell of level 8 or lower). Each casting of Wish causes the tower to regain all its Hit Points.

Wondrous item, uncommon
This box contains a set of parchment cards. A full deck has 34 cards. A deck found as treasure is usually missing 1d20 - 1 cards.
The magic of the deck functions only if cards are drawn at random (you can use an altered deck of playing cards to simulate the deck). You can use an action to draw a card at random from the deck and throw it to the ground at a point within 30 feet of you.
An illusion of one or more creatures forms over the thrown card and remains until dispelled. An illusory creature appears real, of the appropriate size, and behaves as if it were a real creature (as presented in the Monster Manual), except that it can do no harm. While you are within 120 feet of the illusory creature and can see it, you can use an action to move it magically anywhere within 30 feet of its card. Any physical interaction with the illusory creature reveals it to be an illusion, because objects pass through it. Someone who uses an action to visually inspect the creature identifies it as illusory with a successful DC 15 Intelligence (Investigation) check. The creature then appears translucent.
The illusion lasts until its card is moved or the illusion is dispelled. When the illusion ends, the image on its card disappears, and that card can't be used again.

Armor (Any Heavy Armor), Rare (Requires Attunement)
This magic armor appears as a pot of bubbling black ichor. When you attune to it, the ichor adheres to and contours to your skin, and the pot disappears. The armor can be worn under normal clothes, and it doesn’t impede bodily functions. Once you put it on, it can’t be removed unless you choose to do so or you die, at which point the pot reappears and the ichor flows back into it.
While wearing the armor, you have resistance to poison damage. The armor also doesn’t impose disadvantage on Dexterity (Stealth) checks.

Hut des Ungeziefers

Wundersamer Gegenstand, gewöhnlich

Diese staubige alte Mütze hat 3 Ladungen. Während du den Hut in der Hand hältst, kannst du eine Aktion nutzen, um 1 seiner Ladungen zu verbrauchen und ein Befehlswort zu sprechen, das eine Fledermaus, einen Frosch oder eine Ratte herbeiruft (siehe das Spielerhandbuch oder das Monsterhandbuch für Statistiken). Die beschworene Kreatur erscheint auf magische Weise im Hut und versucht, so schnell wie möglich von dir wegzukommen. Die Kreatur ist weder freundlich noch feindlich und steht auch nicht unter deiner Kontrolle. Sie verhält sich wie eine normale Kreatur ihrer Art und verschwindet nach 1 Stunde oder wenn sie auf 0 Trefferpunkte fällt. Der Hut erhält täglich im Morgengrauen alle verbrauchten Ladungen zurück. Wenn du diesen schwarzen Hut mit zwei großen Filzohren trägst, wird dein Name auf magische Weise mit gelben Nähten auf den Hut geschrieben. Wenn du ihn abnimmst, verschwindet der Name. Dieser Gegenstand kann in Xanathars Leitfaden für alles gefunden werden.

Wondrous Item, Rare
You can take a Magic action to blow the horn, which emits a thunderous blast in a 30-foot Cone that is audible out to 600 feet. Each creature in the Cone makes a DC 15 Constitution saving throw. On a failed save, a creature takes 5d8 Thunder damage and has the Deafened condition for 1 minute. On a successful save, a creature takes half as much damage only. Glass or crystal objects in the Cone that aren’t being worn or carried take 10d8 Thunder damage.
Each use of the horn’s magic has a 20 percent chance of causing the horn to explode. The explosion deals 10d6 Force damage to the user and destroys the horn.

Wondrous Item, Rare (Requires Attunement)
You can use an action to blow this horn to cast one of the following spells from it: Arms of Hadar, Fog Cloud, Gust of Wind, or Web. If the spell requires a saving throw, the spell save DC is 13.
Once the horn has been used to cast a spell, it can’t be used to cast that spell again until the next dawn.

Instrument of Illusions

Wondrous Item, Common

While you are playing this musical instrument, you can create harmless, illusionary visual effects within a 5-foot-radius sphere centered on the instrument. If you are a bard, the radius increases to 15 feet. Sample visual effects include luminous musical notes, a spectral dancer, butterflies, and gently falling snow. The magical effects have neither substance nor sound, and they are obviously illusory. The effect ends when you stop playing. This item can be found in Xanathar’s Guide to Everything.

Instrument der Illusionen

Wundersamer Gegenstand, Gemein

Während du dieses Musikinstrument spielst, kannst du harmlose, illusionäre visuelle Effekte in einem Umkreis von 5 Fuß um das Instrument herum erzeugen. Wenn du ein Barde bist, erhöht sich der Radius auf 15 Fuß. Beispiele für visuelle Effekte sind leuchtende Musiknoten, ein spektraler Tänzer, Schmetterlinge und sanft fallender Schnee. Die magischen Effekte haben weder Substanz noch Klang, und sie sind offensichtlich illusorisch. Der Effekt endet, wenn Sie aufhören zu spielen. Dieser Gegenstand kann in Xanathars Handbuch für alles gefunden werden. 

Uncommon
Weapon (javelin), uncommon Simple weapon, melee weapon 2 lb. 1d6 piercing - thrown (30/120 ft.) This javelin is a magic weapon. When you hurl it and speak its command word, it transforms into a bolt of lightning, forming a line 5 feet wide that extends out from you to a target within 120 feet. Each creature in the line excluding you and the target must make a DC 13 Dexterity saving throw, taking 4d6 lightning damage on a failed save, and half as much damage on a successful one. The lightning bolt turns back into a javelin when it reaches the target. Make a ranged weapon attack against the target. On a hit, the target takes damage from the javelin plus 4d6 lightning damage. The javelin's property can't be used again until the next dawn. In the meantime, the javelin can still be used as a magic weapon. Thrown: If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property. Minor Property: Strange Material The item was created from a material that is bizarre given its purpose. Its durability is unaffected.

Wondrous item, uncommon

Invisible creatures and objects are visible as long as they are in the lantern’s bright light. You can use an action to lower the hood, reducing the light to dim light in a 5-foot radius.
