Magic Items

Staff, weapon (Quarterstaff), very rare (requires attunement)

This transparent crystal staff can be wielded as a magic quarterstaff that grants a +3 bonus to attack and damage rolls made with it.

Altered Outcome. The staff has 6 charges. As a bonus action, you can expend 1 of the staff's charges to give yourself or one other creature that you can see a d4. The recipient can roll this d4 and add the number rolled to one ability check, attack roll, damage roll, or saving throw it makes before the start of your next turn. If this extra die is not used before then, it is lost.

If you expend the staff's last charge, roll a d20. On a roll of 9 or lower, the staff becomes a nonmagical quarterstaff that breaks the first time it scores a hit and deals damage. On a roll of 10 or higher, the staff regains 1d6 of its expended charges.

Weapon (longbow), very rare (requires attunement)

When you nock an arrow on this bow, it whispers in Elvish, "Swift defeat to my enemies." When you use this weapon to make a ranged attack, you can, as a command phrase, say, "Swift death to you who have wronged me." The target of your attack becomes your sworn enemy until it dies or until dawn seven days later. You can have only one such sworn enemy at a time. When your sworn enemy dies, you can choose a new one after the next dawn.

When you make a ranged attack roll with this weapon against your sworn enemy, you have advantage on the roll. In addition, your target gains no benefit from cover, other than total cover, and you suffer no disadvantage due to long range. If the attack hits, your sworn enemy takes an extra 3d6 piercing damage.

While your sworn enemy lives, you have disadvantage on attack rolls with all other weapons.

This particular oathbow is made of blackened, cooled lava, its string glowing as if red-hot.

Weapon (greatsword), very rare

You have a +3 bonus to attack and damage rolls made with this magic weapon.

Silvered Weapons
Some monsters that have immunity or resistance to nonmagical weapons are susceptible to silver weap⁠ons, so cautious adventurers invest extra coin to plate their weap⁠ons with silver. You can silver a single weapon or ten pieces of ammunition for 100 gp. This cost represents not only the price of the silver, but the time and expertise needed to add silver to the weapon without making it less effective.

Generic variant (longbow), very rare (requires attunement)

This weapon is decorated with dragon heads, claws, wings, scales, or Draconic letters. When it steeps in a dragon's hoard, it absorbs the energy of the dragon's breath weapon and deals damage of that type with its special properties.

Whenever you roll a 20 on your attack roll with this weapon, each creature of your choice within 5 feet of the target takes 5 damage of the type dealt by the dragon's breath weapon.

You gain a +2 bonus to attack and damage rolls made using the weapon. On a hit, the weapon deals an extra 2d6 damage of the type dealt by the dragon's breath weapon.

As an action, you can unleash a 30-foot cone of destructive energy from the weapon. Each creature in that area must make a DC 16 Dexterity saving throw, taking 8d6 damage of the type dealt by the dragon's breath weapon on a failed save, or half as much damage on a successful one. Once this action is used, it can't be used again until the next dawn.

Ring, very rare (requires attunement)
This ring is carved from hematite and bears an engraving of the friend rune.

When you first attune to this ring, you can touch one willing creature and form a magical bond between the two of you. While this bond lasts, whenever you are subjected to a spell or magical effect that restores hit points, the bonded creature also receives the benefits of the spell or effect.

You can bond with a different creature whenever you finish a long rest, provided that you can touch the creature and the creature is willing.

A creature can benefit from only one ring of amity's bond at a time. The bond ends if either you or the creature travels to a different plane of existence, if you bond with a different creature at the end of a long rest, or if you sever the bond as a bonus action.

Invoking the Rune. When the bonded creature hits a target with an attack roll, you can use your reaction to invoke the ring's rune if you are within 60 feet of the bonded creature. The bonded creature's attack is then turned into a critical hit.
Once the rune has been invoked, it can't be invoked again until the next dawn.
