+3 Arcane Grimoire "Book of Trios" Very Rare (BMG-MOON-MD-08) (Attune Wizard)
Wondrous Item, Very Rare (Requires Attunement by a Wizard)
Function:
While you are holding this leather-bound book, you can use it as a spellcasting focus for your wizard spells, and you gain a bonus to spell attack rolls and to the saving throw DCs of your wizard spells. The bonus is determined by the book's rarity (+3).
You can use this book as a spellbook. In addition, when you use your Arcane Recovery feature, you can increase the number of spell slot levels you regain by 1.
Description:
This old book, titled “Book of Trios”, is remarkably well-preserved. Its brown and gold cover is coated with a fine layer of pixie dust, which gets on everything it touches. When a spell is cast from the book, the pixie dust swirls into a glittering aura of arcane energy around the caster.

Staff, weapon (quarterstaff), very rare (requires attunement)
The Staff of Fate appears to have been intricately grown over with elm wood, concealing its true nature. Yet, the allure of blue crystals peeking through the wood's knots and at its end hints at its mystical power, cleverly masquerading as a mere walking stick.

This transparent crystal staff can be wielded as a magic quarterstaff that grants a +3 bonus to attack and damage rolls made with it. Altered Outcome. The staff has 6 charges. As a bonus action, you can expend 1 of the staff's charges to give yourself or one other creature that you can see a d4. The recipient can roll this d4 and add the number rolled to one ability check, attack roll, damage roll, or saving throw it makes before the start of your next turn. If this extra die is not used before then, it is lost. If you expend the staff's last charge, roll a d20. On a roll of 9 or lower, the staff becomes a nonmagical quarterstaff that breaks the first time it scores a hit and deals damage. On a roll of 10 or higher, the staff regains 1d6 of its expended charges. Versatile. This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.

Ring, uncommon (requires attunement)
This unassuming ring crafted from black silver features three striking red rubies. Curiously, it appears to possess a consciousness of its own and may withhold its powers until
the following dawn if it senses you speaking falsehoods or engaging in malicious actions. While wearing this ring, you have advantage on Wisdom (Insight) checks to determine whether someone is lying to you.

Weapon (arrow), common
This arrow can’t be broken, except when it is within an antimagic field.

Armor (shield), very rare (requires attunement)
This shield is made from the scale of an ancient white dragon. It has a rune burned into its outward-facing side. A character who examines the rune and succeeds on a DC 20 Intelligence (History) check recognizes it as an uven (“enemy” in Giant) rune that confers great power.

While holding the shield, you benefit from the following properties.

Winter’s Friend. You are immune to cold damage.

Deadly Rebuke. Immediately after a creature hits you with a melee attack, you can use your reaction to deal 3d6 necrotic damage to that creature.

Bane. You can cast the bane spell from the shield (save DC 17). The spell does not require concentration and lasts for 1 minute. Once you cast the spell from the shield, you can’t do so again until you finish a short or long rest.

Gift of Vengeance. You can transfer the shield’s magic to a nonmagical weapon by tracing the uven rune on the weapon with one finger. The transfer takes 8 hours of work that requires the two items to be within 5 feet of each other. At the end, the shield is destroyed, and the rune is etched or burned into the chosen weapon. This weapon becomes a rare magic item that requires attunement. It has the properties of a +1 weapon. The bonus increases to +3 when the weapon is used against one of the following creature types, chosen by you at the time of the magic weapon’s creation: aberrations, celestials, constructs, dragons, elementals, fey, fiends, giants, or undead.

A shield is made from wood or metal and is carried in one hand. Wielding a shield increases your Armor Class by 2. You can benefit from only one shield at a time.

A vertical column of divine fire roars down from the heavens in a location you specify. Each creature in a 10-foot-radius, 40-foot-high cylinder centered on a point within range must make a Dexterity saving throw. A creature takes 4d6 fire damage and 4d6 radiant damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the fire damage or the radiant damage (your choice) increases by 1d6 for each slot level above 5th.

Potion, rare
For 1 minute after you drink this potion, you have resistance to all damage. The potion's syrupy liquid looks like liquefied iron.

Armor (shield), 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. While holding this shield, you have a bonus to AC determined by the shield’s rarity. This bonus is in addition to the shield’s normal bonus to AC.
