Magic Items

Necklace of Fireballs
Wondrous item, rare

This necklace has 1d6 + 3 beads hanging from it. You can use an action to detach a bead and throw it up to 60 feet away. When it reaches the end of its trajectory, the bead detonates as a 3rd-level fireball spell (save DC 15).

You can hurl multiple beads, or even the whole necklace, as one action. When you do so, increase the level of the fireball by 1 for each bead beyond the first.

Weapon (longsword), rare (requires attunement)

This item appears to be a longsword hilt. While grasping the hilt, you can use a bonus action to cause a blade of pure radiance to spring into existence, or make the blade disappear. While the blade exists, this magic longsword has the finesse property. If you are proficient with shortswords or longswords, you are proficient with the sun blade.

You gain a +2 bonus to attack and damage rolls made with this weapon, which deals radiant damage instead of slashing damage. When you hit an undead with it, that target takes an extra 1d8 radiant damage.

The sword's luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. While the blade persists, you can use an action to expand or reduce its radius of bright and dim light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.

Dragon Scale Mail
Armor (scale mail), very rare (requires attunement)

Dragon scale mail is made of the scales of one kind of dragon. Sometimes dragons collect their cast-off scales and gift them to humanoids. Other times, hunters carefully skin and preserve the hide of a dead dragon. In either case, dragon scale mail is highly valued.

While wearing this armor, you gain a +1 bonus to AC, you have advantage on saving throws against the Frightful Presence and breath weapons of dragons, and you have resistance to one damage type that is determined by the kind of dragon that provided the scales (see the table).

Additionally, you can focus your senses as an action to magically discern the distance and direction to the closest dragon within 30 miles of you that is of the same type as the armor. This special action can’t be used again until the next dawn.

Staff, Rare (Requires Attunement by a Bard, Sorcerer, Warlock, or Wizard)

This slender, hollow staff is made of glass yet is as strong as oak. It weighs 3 pounds. While holding the staff, you have a +1 bonus to your Armor Class.

Spells. The staff has 10 charges. While holding it, you can expend the requisite number of charges to cast one of the following spells from the staff: mage armor (1 charge) or shield (2 charges).

The staff regains 1d6 + 4 expended charges each day at dawn. If you expend the staff's last charge, roll a d20. On a 1, the staff shatters and is destroyed.
