Magic Items

Rod, rare (requires attunement)
Major tier
2 lb.
Made by the drow, this rod is a magic weapon that ends in three rubbery tentacles. While holding the rod, you can use an action to direct each tentacle to attack a creature you can see within 15 feet of you. Each tentacle makes a melee attack roll with a +9 bonus. On a hit, the tentacle deals 1d6 bludgeoning damage. If you hit a target with all three tentacles, it must make a DC 15 Constitution saving throw. On a failure, the creature's speed is halved, it has disadvantage on Dexterity saving throws, and it can't use reactions for 1 minute. Moreover, on each of its turns, it can take either an action or a bonus action, but not both. At the end of each of its turns, it can repeat the saving throw, ending the effect on itself on a success.

Wondrous Item, uncommon

While you wear these boots, you have a flying speed equal to your walking speed. You can use the boots to fly for up to 4 hours, all at once or in several shorter flights, each one using a minimum of 1 minute from the duration. If you are flying when the duration expires, you descend at a rate of 30 feet per round until you land.
The boots regain 2 hours of flying capability for every 12 hours they aren't in use.
These boots appear to be made from hundreds of bees crawling over the wearer’s feet. While flying, they make an extremely loud buzzing noise.

Discord
Armor (Plate), Unique

Discord is comprised of sharp, interlocking spikes of green crystal and extinguishes all nonmagical flames within 30 feet of it. A creature wearing Discord hears insidious whispers originating from a point just beyond their peripheral vision. Unless deafened, the creature has disadvantage on saving throws caused by, and on Wisdom checks related to, Father Llymic and its allies.
While wearing this armor, you gain a +2 bonus to AC. In addition, you can use your reaction to see normally in darkness, both magical and nonmagical, out to a distance of 120 feet until the start of your next turn. Discord can’t be used this way again until the next dawn.
If a character wields Woe (a longsword) while wearing Discord, they are unharmed by temperatures as low as −60 degrees Fahrenheit.

Weapon (Greatsword), Common

The flats of the blade act like windows onto a night sky with blinking stars and a large viridian sphere shifting slowly in different directions. Three sluggish, green tentacles protrude from one end of the blade, acting as its guard and grip. The light the blade produces is green in color, and emitted from the viridian sphere.
