Magic Items

(reminiscent of your shield guardian modifications),

Rod, very rare (Requires Attunement by a Warlock)

Formed from the severed tentacle of a powerful star spawn, this rod plagues its wielder with dreams of alien creatures that beckon them to travel deep within the Thunder Peaks, where something patiently awaits their arrival.
While holding this rod, you gain a +3 bonus to spell attack rolls and to the saving throw DCs of your warlock spells. In addition, you can regain 1 warlock spell slot as an action while holding the rod. You can’t use this property again until you finish a long rest.

Very Rare
This shield appears as a shroud of shadow with the symbol of the Raven Queen glowing in dim red light.
While holding this shield, nonmagical flames are extinguished within 30 feet of you as the shadow lashes out at the flame. The shield encourages you to hold no pity for those who suffer and die, for death is the natural end of life

Armor (shield), rare (requires attunement)

This gold-trimmed red shield is emblazoned with Candlekeep’s coat of arms.
You gain a +2 bonus to AC against ranged attacks while you wield this shield. This bonus is in addition to the shield’s normal bonus to AC. In addition, whenever an attacker makes a ranged attack against a target within 5 feet of you, you can use your reaction to become the target of the attack instead.

Wondrous item, uncommon (requires attunement)

These dark-red bracers with golden trim bear the seal of Candlekeep’s Gatewarden.
While wearing these bracers, you have proficiency with the longbow and shortbow, and you gain a +2 bonus to damage rolls on ranged attacks made with such weapons.

Illithid tech flavour

Wondrous Item, Major, Uncommon (Requires Attunement)
You gain a +1 bonus to AC and saving throws while you wear this cloak

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.

Armor (plate), very rare
While wearing this armor, you gain a +2 bonus to AC. In addition, if an effect moves you against your will along the ground, you can use your reaction to reduce the distance you are moved by up to 10 feet.

Wondrous item, rare (requires attunement by a sorcerer)
1 lb.
This writhing crystal is steeped in the warped essence of the Far Realm. As an action, you can attach the shard to a Tiny object (such as a weapon or a piece of jewelry) or detach it. It falls off if your attunement to it ends. You can use the shard as a spellcasting focus while you hold or wear it.

When you use a Metamagic option on a spell while you are holding or wearing the shard, you can cause a slimy tentacle to rip through the fabric of reality and strike one creature you can see within 30 feet of you. The creature must succeed on a Charisma saving throw against your spell save DC or take 3d6 psychic damage and become frightened of you until the start of your next turn.

Wondrous item, major tier, rare
A figurine of wondrous power is a statuette of a beast small enough to fit in a pocket. If you use an action to speak the command word and throw the figurine to a point on the ground within 60 feet of you, the figurine becomes a living creature. If the space where the creature would appear is occupied by other creatures or objects, or if there isn't enough space for the creature, the figurine doesn't become a creature.

The creature is friendly to you and your companions. It understands your languages and obeys your spoken commands. If you issue no commands, the creature defends itself but takes no other actions.

The creature exists for a duration specific to each figurine. At the end of the duration, the creature reverts to its figurine form. It reverts to a figurine early if it drops to 0 hit points or if you use an action to speak the command word again while touching it. When the creature becomes a figurine again, its property can't be used again until a certain amount of time has passed, as specified in the figurine's description.

Golden Lions.

These gold statuettes of lions are always created in pairs. You can use one figurine or both simultaneously. Each can become a lion for up to 1 hour. Once a lion has been used, it can't be used again until 7 days have passed.

The lions that appear are twinned pairs of
opposite colouration. One white with black stripes,
the other black with white stripes.

Gauntlets of Ogre Power
DMG
p171
Wondrous item, uncommon (requires attunement)
Major tier
Your Strength score is 19 while you wear these gauntlets. They have no effect on you if your Strength is already 19 or higher without them.

Wondrous item, very rare (requires attunement)
Major tier
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.

This translucent green stone came from the Far Realm.

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.
