Magic Items

It uses the stat block of a giant poisonous snake.
The serpent is a construct that understands and obeys whoever was holding the staff when it transformed.
It has immunity to poison damage and the poisoned condition. It doesn’t require air, food, drink, or sleep.
When it drops to 0 hit points, roll a d6. On a roll of 1, the snake turns to dust and is destroyed. On any other roll, it changes back into a staff and breaks into 1d4 + 1 pieces that must be magically mended before the staff can be used again.

Wondrous Item, Very Rare (Requires Attunement by a Wizard) 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. 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.

Shield, very rare (requires attunement)

While holding this Shield, you have Advantage on saving throws against spells and other magical effects, and spell attack rolls have Disadvantage against you.

This silver-and-black bow is engraved with the phases of the moon. You gain a +1 bonus to attack and damage rolls made with this magic weapon.

When you hit with a ranged attack roll using this magic bow, the target takes an extra 1d6 radiant damage. If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you make a ranged attack with it. The ammunition created by the bow vanishes the instant after it hits or misses a target.

While wielding this magic bow, you can use a bonus action to enter a semi-incorporeal state until the start of your next turn. While semi-incorporeal, you have resistance to bludgeoning, piercing, and slashing damage. Once this bonus action is used, it can’t be used again until the next dawn.

This twelve-sided metal die is 12 inches across and bears the numbers 1 through 12 engraved on its pentagonal sides. The dodecahedron contains arcane clockwork mechanisms that whir and click whenever the die is cast.

The dodecahedron can be hurled up to 60 feet as an action. A random magical effect occurs when the die comes to rest after rolling across the ground for at least 10 feet. If an effect requires a target and no eligible target is within range, nothing happens. Spells cast by the dodecahedron require no components. Roll a d12 and consult the following table to determine the effect:

Roll Table to VTT

1–2 The dodecahedron explodes and is destroyed. Each creature within 20 feet of the exploding die must make a DC 13 Dexterity saving throw, taking 40 (9d8) force damage on a failed save, or half as much damage on a successful one.
3–4 The dodecahedron casts light on itself. The effect lasts until a creature touches the die.
5–6 The dodecahedron casts ray of frost (+5 to hit), targeting a random creature within 60 feet of it that doesn’t have total cover against the attack.
7–8 The dodecahedron casts shocking grasp (+5 to hit) on the next creature that touches it.
9–10 The dodecahedron casts darkness on itself. The effect has a duration of 10 minutes.
11–12 The next creature to touch the dodecahedron gains 1d10 temporary hit points that last for 1 hour.
