Magic Items

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 brass horn summons 3d4 + 3
berserkers and requires proficiency with all
simple 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. This item is found in the
Dungeon Master’s Guide. This gleaming brass horn has flaming swords,
the holy symbols of Tempus, etched all along its
length. The horn instills eagerness for battle in
its bearer.

Flavor
This necklace has 6 beads. Every time you use one, the bead turns into a back scratcher hand for you to scratch your back and when you do use them to scratch your back, it lets out a very loud "FEELS GOOD YEAH!?" sound.

This dark-purple necklace bears the symbol of Mystryl. Its final bits of power wards off all poisons and glows when it detects undead creatures.

Weapon (Rapier), legendary (requires attunement by a Creature of the Weapon’s Choice: In this case, a creature that has the story award 'Moon Dancer')

Moonblade Property. A Moonblade has one rune on it for each bearer it has willingly served (typically 1d6 + 1). The first rune grants a +1 bonus to attack rolls and damage rolls made with this magic weapon. Each rune beyond the first grants the Moonblade an additional property:
Its weapon’s bonus to attack rolls and damage roll is already increased to +3.
When the user hits with an attack roll using the moonblade, they deal 3d6 force damage on a hit.
The Moonblade scores a Critical hit on a roll of 19 or 20 on the D20.
The Moonblade has the properties of a Ring of Spell Storing. (Dispel Evil and Good)
You can take a Bonus Action to cause the Moonblade to flash brightly. Each other creature that is within 30 feet of you and not behind Total Cover must succeed on a DC 15 Constitution saving throw or have the Blinded condition for 1 minute. A creature repeats the save at the end of each of its turns, ending the effect on itself on a success. You can’t use this property again until you finish a Short or Long Rest.

Minor Property. In addition to its aforementioned properties, each Moonblade has a minor property determined by rolling on the Magic Item’s Minor Property table. This Moonblade has the Warleader Property.

Sentience. A Moonblade is a sentient weapon with an Intelligence of 12, a Wisdom of 10, and a Charisma of 12. It has hearing and Darkvision out to 120 feet. Its alignment matches that of its creator.

The weapon communicates by transmitting emotions, sending a tingling sensation through the wielder’s hand when it wants to communicate something it has sensed. It can communicate through visions or dreams when the wielder is either in a trance or asleep.

Personality. Quiet and composed, but with a fiery passion to save all drows from the grasp of Lolth, when the Moondance Rapier of Eilistraee hears or witnessed any drow in dire need of help against the schemes of Lolth, it urges its wielder to pick up the mantle and save them.

Flavor: This rapier's body holds engravings of the dance dedicated to Eilistraee step by step. The blade is forged with some of the rarest minerals in the Underdark and blessed by Eilistraee, emitting an thin layer of purple aura coating its body. Its hilt is also decorated with beautiful white and purple Underdark flowers. (edited)

This dragonhide belt is made from the scales of the ‘Purple Dragon Reborn’. Whenever a creature is stunned by the wearer, the scales flare purple and a dragon roar booms proudly.

This red cape, when donned, flies its wearer up to 80 ft, or when commanded, spreads itself into a carpet. Upon sensing danger, the carpet nudges its wearer, warning them of danger and granting a +2 to initiative.
