Magic Items

The typical crystal ball is about 6 inches in diameter. While touching it, you can cast the scrying spell (save DC 17) with it.
Crystal Ball of True Seeing. While scrying with the crystal ball, you have truesight with a radius of 120 feet centered on the spell's sensor.

Weapon (dagger), rare
You gain a +1 bonus to attack and damage rolls made with this magic weapon.

You can use an action to cause thick, black poison to coat the blade. The poison remains for 1 minute or until an attack using this weapon hits a creature. That creature must succeed on a DC 15 Constitution saving throw or take 2d10 poison damage and become poisoned for 1 minute. The dagger can’t be used this way again until the next dawn.

Weapon (any sword), rare (requires attunement)
You can use a bonus action to speak this magic sword’s command word, causing flames to erupt from the blade. These flames shed bright light in a 40-foot radius and dim light for an additional 40 feet. While the sword is ablaze, it deals an extra 2d6 fire damage to any target it hits. The flames last until you use a bonus action to speak the command word again or until you drop or sheathe the sword.
A character attuned to this sword can use an action to mentally command it to detect gems and jewels. Someone who does so learns the kind and number of such objects within 60 feet of the sword.

While wearing these gloves, climbing and swimming don't cost you extra movement, and you gain a +5 bonus to Strength (Athletics) checks made to climb or swim.

Item Flavor: This headband made of bone bears the sigil of the wizard Denlor, whose tower still stands in the city.

Wondrous item, rare (requires attunement)
This dark cloak is made of cured hell hound hide. As an action, you can command the cloak to transform you into a hell hound for up to 1 hour. The transformation otherwise functions as the polymorph spell, but you can use a bonus action to revert to your normal form.
Curse. This cloak is cursed with the essence of a hell hound, and becoming attuned to it extends the curse to you. Until the curse is broken with remove curse or similar magic, you are unwilling to part with the cloak, keeping it within reach at all times.
The sixth time you use the cloak, and each time thereafter, you must make a DC 15 Charisma saving throw. On a failed save, the transformation lasts until dispelled or until you drop to 0 hit points, and you can’t willingly return to normal form. If you ever remain in hell hound form for 6 hours, the transformation becomes permanent and you lose your sense of self. All your statistics are then replaced by those of a hell hound. Thereafter, only remove curse or similar magic allows you to regain your identity and return to normal. If you remain in this permanent form for 6 days, only a wish spell can reverse the transformation.

Wondrous item, rare

You can use an action to blow this horn. In response, 3d4+4 warrior spirits come from the Abyss and appear within 60 feet of you. They use the statistics of a berserker and look like minotaurs. Once you use the horn, it can't be used again until 7 days have passed.
