Magic Items

Black Crystal Tablet
Wondrous item, legendary (requires attunement by a creature that has proficiency in the Arcana skill)

The black crystal tablet is a legendary magic item that requires attunement by a creature that has proficiency in the Arcana skill. Any creature that attunes to the tablet must make a DC 20 Wisdom saving throw at the end of its next long rest. On a failed save, the creature becomes afflicted with a random form of long-term madness.

As an action, a creature attuned to the black crystal tablet can use it to cast eyebite or gate (the portal created by this spell links to the Far Realm only). After the tablet is used to cast a spell, it cannot be used again until the next dawn.

Mace of Smiting
Weapon (mace), rare

You gain a +1 bonus to attack and damage rolls made with this magic weapon. The bonus increases to +3 when you use the mace to attack a construct.

When you roll a 20 on an attack roll made with this weapon, the target takes an extra 2d6 bludgeoning damage, or an extra 4d6 bludgeoning damage if it's a construct. If a construct has 25 hit points or fewer after taking this damage, it is destroyed.

You gain a +2 bonus to attack rolls and damage rolls made with this magic weapon. In addition, you can make one attack with it as a Bonus Action on each of your turns.

Wondrous Item, Uncommon

These crystal lenses fit over the eyes. While wearing them, your vision improves significantly out to a range of 1 foot, granting you Darkvision within that range and Advantage on Intelligence (Investigation) checks made to examine something within that range.

Ring, Rare (Requires Attunement)

While you wear this ring, Difficult Terrain doesn’t cost you extra movement. In addition, magic can neither reduce any of your Speeds nor cause you to have the Paralyzed or Restrained condition.

Stonespeaker Crystal
Wondrous item, rare (requires attunement)
Created by the stone giant librarians of Gravenhollow, this nineteen-inch-long shard of quartz grants you advantage on Intelligence (Investigation) checks while it is on your person.
The crystal has 10 charges. While holding it, you can use an action to expend some of its charges to cast one of the following spells from it: speak with animals (2 charges), speak with dead (4 charges), or speak with plants (3 charges).
When you cast a divination spell, you can use the crystal in place of one material component that would normally be consumed by the spell, at a cost of 1 charge per level of the spell. The crystal is not consumed when used in this way.
The crystal regains 1d6 + 4 expended charges daily at dawn. If you expend the crystal’s last charge, roll a d20. On a 1, the crystal vanishes, lost forever.

Weapon (Shortsword), Rare

You have a +2 bonus to attack rolls and damage rolls made with this magic weapon.

Wondrous Item, Uncommon

This bag has an interior space considerably larger than its outside dimensions—roughly 2 feet square and 4 feet deep on the inside. The bag can hold up to 500 pounds, not exceeding a volume of 64 cubic feet. The bag weighs 5 pounds, regardless of its contents. Retrieving an item from the bag requires a Utilize action.

If the bag is overloaded, pierced, or torn, it is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth unharmed, but the bag must be put right before it can be used again. The bag holds enough air for 10 minutes of breathing, divided by the number of breathing creatures inside.

Placing a Bag of Holding inside an extradimensional space created by a Handy Haversack, Portable Hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within a 10-foot-radius Sphere centered on the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way and can’t be reopened.

Spider Walk. You can’t be caught in webs of any sort and can move through webs as if they were Difficult Terrain.

Web. You can cast Web (save DC 13). The web created by the spell fills twice its normal area. Once used, this property can’t be used again until the next dawn.
