New Magic Items
These magic items are Hombrew Story Awards, thus they only work at my tables.
Still they count to the maximum of magic items you can take to an adventure regarding the V.A.L.U.E. rules.
A character, who has such an item, can give can give it to another character during an \y game at my tables.
… Sheshka (by @BufoBufo) had this item 
Talisman of Annihilation (Charge Used)
Wondrous item, artifact (requires attunement by a spellcaster of good alignment)
You found this talisman in the Whispering Cairn.
Sheshka has the feeling that by passing Icosiol’s final test something has been unlocked. After defeating Mazyralx the artifact had 1 charge. She spend the charge to defeat the final form of Kyuss.As an action you could spend a charge to create a 20 feet radius “sphere of annihilation” within 200 feet, that would desintegrate everything in its area. Creatures on the border of that area can save themselves by succeeding on a DC 25 Dexterity saving throw, that would only deal them 4d10 force damage on a success instead of being desintegrated.
Very powerful creatures could still withstand such annihilation, but would be weakened.
Note: Controlling the “annihilation zone” would be a spellcasting ability check + double your proficiency bonus.
… Hogar (by @Stracci) had those items
Thunder & Lightning (Exalted)
Weapon, legendary (requires attunement)
Martial weapon, melee weapon, 3 lb.
Each is an ancient khopesh (scimitar) forged of Byeshk (a magic metal) wielded by Icosiol, the general of the Wind Dukes of Aaqa pledged to the Couatls during the Age of Demons.
During those dark times they became best friends and are really wanted to be used together.You have to attune to both weapons to get the benefits.
So they count as two magic items and take up two attunement slots.
Both share a hidden Loyalty stat with you, that could unlock more potent abilities later.
Giving the weapons to another character resets their Loyalty to their Dormant levels.
Exalted
Thunder is a +3 scimitar in its exalted state, that also deals an extra 3d6 thunder damage to any target it hits. Also if Thunder in your main hand, you can cast thunder step (DC 17) as a 5th level spell once, as long as hostile creatures are within 10 feet around you.
Lightning is a +3 scimitar in its awakened state, that also deals an extra 3d6 lightning damage to any target it hits. Also if Lightning in your main hand, you can cast lightning bolt (DC 17) as a 5th level spell once, as long as hostile creatures are in the affected area.
Should both spells have been expended, you will regain both at the next dawn.Additionally, should you wield both weapons at the same time, you can cast whirlwind (DC 17) at will as a 7th level spell, but every time you do so, you will gain one level of exhaustion.
Sentience.
Thunder as well as Lightning are sentient chaotic good weapons with an Intelligence of 15, a Wisdom of 16, and a Charisma of 20. They each have hearing and darkvision out to a range of 120 feet.
The scimitars can read, and understand Auran, and they can communicate with their wielder telepathically transmitting their emotions. They know every language you know while attuned to it.
Personality.
Battle-loving djinn live within Thunder & Lightning. The weapons desire to push their wielder to use only them in combat and also to don’t favor one blade over the other as they can get quite jealous.
Curse.
These weapons are cursed, and becoming attuned to them extends the curse to you. While attuned to these weapons, you have disadvantage on attack rolls except on weapon attacks made by these scimitars.You can break the curse in the usual ways. Additonally the scimitars can end the curse as well as ending your attunement to two both weapons at any point in time. Also when you wield both weapons at the same time, they can choose to attune you to them.

… Hewguard (by @PatrickD) had this item, used it and it exploded and splintered again …
Rod of Seven Parts (Rod of Law)
Weapon (mace), artifact (requires attunement)
Simple weapon, melee weapon, 4 lb.
Your group has found a strange metallic piece in the grave of the final room of the from Whispering Cairn. Detect magic only revealed that It radiates a strong aura of Law.
Later you got another one from the Mistmarsh lizardfolk shaman.
You got two more from an elven cleric of the Undying Court and another one from Icosiol’s tomb. You also found one during the visit of past stories at the Fountain of Former Fortune’s Folly The last piece was a spliter that got struck in Mazyralyx’s bones.
As the pieces touched, they fused into a larger piece.
The mace is very unstable and breaks easily. Should you hit an aberrations, fiend, or undead with the weapon, the rod explodes and that creature will be banished to Khyber.
The strength of the explosion depends on the strength of the banished creature.
Very powerful creatures could still withstand such a hit, but would be weakened.
Should you miss an attack roll by 10 or more, the rod would break and explode without having any effect.
