Magic Items

Wondrous Item, Rare (Requires Attunement by a Wizard)
The spine of a small mammalian creature is embedded in this book’s binding, and its cover is inset with a pair of tiny, beadlike eyeballs that are perfectly preserved.
Acrid odors cling to this stained, heavy volume. The book’s metal fittings are copper, iron, lead, silver, and gold, some frozen mid-transition from one metal to another. When found, the book contains the following spells: enlarge/reduce, feather fall, flesh to stone, gaseous form, magic weapon, and polymorph. It functions as a spellbook for you.

While you are holding the book, you can use it as a spellcasting focus for your wizard spells. The book has 3 charges, and it regains 1d3 expended charges daily at dawn. You can use the charges in the following ways while holding it:
• If you spend 1 minute studying the book, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the book. The new spell must be of the transmutation school.
• As an action, you can touch a nonmagical object that isn’t being worn or carried and spend a number of
charges to transform the object into another object.
For 1 charge, the object can be no larger than 1 foot on a side. You can spend additional charges to increase the maximum dimensions by 2 feet per charge. The new object must have a gold value equal to or less than the original.

Wondrous item, rare (requires attunement by a sorcerer)

This crystal is a solidified shard of the Astral Plane, swirling with silver mist. 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, immediately after casting the spell you can teleport to an unoccupied space you can see within 30 feet of you.

Wondrous item, uncommon (requires attunement)

While you wear these boots, your walking speed becomes 30 feet, unless your walking speed is higher, and your speed isn’t reduced if you are encumbered or wearing heavy armor. In addition, you can jump three times the normal distance, though you can’t jump farther than your remaining movement would allow.

Wondrous item, rare

This hollow metal tube measures about 1 foot long and weighs 1 pound. You can strike it as an action, pointing it at an object within 120 feet of you that can be opened, such as a door, lid, or lock. The chime issues a clear tone, and one lock or latch on the object opens unless the sound can’t reach the object. If no locks or latches remain, the object itself opens.

The chime can be used ten times. After the tenth time, it cracks and becomes useless.

Wondrous Item, Common
The mechanism in this small amulet makes a sound that more closely resembles a heartbeat than a ticking clock. This copper amulet contains tiny interlocking gears and is powered by magic from Mechanus, a plane of clockwork predictability. A creature that puts an ear to the amulet can hear faint ticking and whirring noises coming from within.
When you make an attack roll while wearing the amulet, you can forgo rolling the d20 to get a 10 on the die. Once used, this property can’t be used again until the next dawn.

Wondrous item, uncommon

While lit, this hooded lantern burns for 6 hours on 1 pint of oil, shedding bright light in a 30-foot radius and dim light for an additional 30 feet. Invisible creatures and objects are visible as long as they are in the lantern’s bright light. You can use an action to lower the hood, reducing the light to dim light in a 5-foot radius.
