Magic Items

Weapon (any), uncommon (requires attunement)
This magic weapon warns you of danger. While the weapon is on your person, you have advantage on initiative rolls. In addition, you and any of your companions within 30 feet of you can’t be surprised, except when incapacitated by something other than nonmagical sleep. The weapon magically awakens you and your companions within range if any of you are sleeping naturally when combat begins.

Ring, uncommon (requires attunement)
While wearing this ring, you are immune to magic that allows other creatures to read your thoughts, determine whether you are lying, know your alignment, or know your creature type. Creatures can telepathically communicate with you only if you allow it.

You can use an action to cause the ring to become invisible until you use another action to make it visible, until you remove the ring, or until you die.

If you die while wearing the ring, your soul enters it, unless it already houses a soul. You can remain in the ring or depart for the afterlife. As long as your soul is in the ring, you can telepathically communicate with any creature wearing it. A wearer can’t prevent this telepathic communication.

Staff, very rare (requires attunement by a druid, sorcerer, warlock, or wizard)
You have resistance to cold damage while you hold this staff.

The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: cone of cold (5 charges), fog cloud (1 charge), ice storm (4 charges), or wall of ice (4 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns to water and is destroyed.

Ring, rare (requires attunement)
You have resistance to fire damage while wearing this garnet ring.

Weapon (any sword), very rare (requires attunement)
When you hit with an attack using this magic sword, the target takes an extra 1d6 cold damage. In addition, while you hold the sword, you have resistance to fire damage.

In freezing temperatures, the blade sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

When you draw this weapon, you can extinguish all non-magical flames within 30 feet of you. This property can be used no more than once per hour.

Wondrous Item, uncommon (requires attunement)
While you wear this pendant, you stabilize whenever you are dying at the start of your turn. In addition, whenever you roll a Hit Die to regain hit points, double the number of hit points it restores.

Weapon (warhammer), legendary (requires attunemenc by a dwarf)
Whelm is a powerful warhammer forged by dwarves and lost in the dungeon of White Plume Mountain.
You gain a +3 bonus to attack and damage rolls made with this magic weapon. At dawn the day after
you first make an attack roll with Whelm, you develop a fear of being outdoors that persists as long as you remain attuned to the weapon. This causes you to have disadvantage on attack rolls, saving throws, and ability checks while you can see the daytime sky.

Thrown Weapon. Whelm has the thrown property, with a normal range of 20 feet and a long range of 60
feet. When you hit with a ranged weapon attack using it, the target takes an extra 1d8 bludgeoning damage, or an extra 2d8 bludgeoning damage if the target is a giant. Each time you throw the weapon, it flies back to your hand after the attack. If you don't have a hand free, the weapon lands at your feet.

Shock Wave. You can use an action to strike the ground with Whelm and send a shock wave out from
the point of impact. Each creature of your choice on the ground within 60 feet of that point must succeed on a DC 15 Constitution saving throw or become stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once used, this property can't be used again until the next dawn.

Supernatural Awareness. While you are holding the weapon, it alerts you to the location of any secret or concealed doors within 30 feet of you. In addition, you can use an action to cast detect evil and good or locate object from the weapon. Once you cast either spell, you can't cast it from the weapon again until the next dawn.

Sentience. Whelm is a sentient lawful neutral weapon with an Intelligence of 15, a Wisdom of 12, and a Charisma of 15. It has hearing and darkvision out to a range of 120 feet.
The weapon communicates telepathically with its wielder and can speak, read, and understand Dwarvish,
Giant, and Goblin. It shouts battle cries in Dwarvish when used in combat.

Personality. Whelm's purpose is to slaughter giants and goblinoids. It also seeks to protect dwarves against all enemies. Conflict arises if the wielder fails to destroy goblins and giants or to protect dwarves.
Whelm has ties to the dwarf clan that created it, variously called the Dankil or the Mightyhammer clan. It longs to be returned to that clan. It would do anything to protect those dwarves from harm.
The hammer also carries a secret shame. Centuries ago, a dwarf named Ctenmiir wielded it valiantly for a time. But Ctenmiir was turned into a vampire. His will was strong enough that he bent Whelm to his evil
purposes, even killing members of his own clan.

Requires Attunement

This ring stores Spells cast into it, holding them until the attuned wearer uses them. The ring can store up to 5 levels worth of Spells at a time. When found, it contains 1d6 - 1 levels of stored Spells chosen by the DM.

Any creature can Cast a Spell of 1st through 5th Level into the ring by touching the ring as the spell is cast. The spell has no Effect, other than to be stored in the ring. If the ring can't hold the spell, the spell is expended without Effect. The level of the slot used to cast the spell determines how much space it uses.

While wearing this ring, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell Attack bonus, and Spellcasting Ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the ring is no longer stored in it, freeing up space.

Ring, very rare (requires attunement)

While wearing this ring, you regain 1d6 hit points every 10 minutes, provided that you have at least 1 hit point. If you lose a body part, the ring causes the missing part to regrow and return to full functionality after 1d6 + 1 days if you have at least 1 hit point the whole time.
