Vorthekaan's Shackle
Vorthekaan was a warlord of the Ashen Age who could not die on any battlefield — for he had bound his ambition into a ring hammered from the iron of a fallen sky-stone, quenched in the heart of a living storm. When heroes finally pulled him down, they could not destroy the ring, only bury it beneath a mountain that no longer has a name. The ring remembers his hunger: always forward, always toward the bleeding, always consuming. Those who wield it call themselves heroes. Vorthekaan called himself the same.
Mechanics
A cursed ring of ancient lightning that brands its wearer as a storm-vessel, granting devastating electrical power while slowly binding the soul to a long-dead tyrant's will.
Curse
The ring cannot be removed once attuned unless the wearer is targeted by a Remove Curse spell of 5th level or higher, or the ring is destroyed. The curse is not apparent until the wearer first uses one of the ring's active abilities, at which point a crackling brand of interlocked lightning bolts scorches itself into the skin of the ring finger — visible through any glove. While cursed, the wearer cannot willingly move away from a creature they can see that has fewer than half its maximum hit points; they must move toward or attack that creature if able to do so on their turn. Additionally, at the end of each long rest, the wearer must succeed on a DC 16 Wisdom saving throw or suffer the Frightened condition until the end of their next short or long rest, as Vorthekaan's ancient hunger claws at the edges of their consciousness.
Storm Vessel — 8 Charges
The ring holds 8 charges and regains 1d6+2 expended charges at dawn. All active abilities below draw from this pool.
Chain of Ruin
As an action, expend 2 charges. A bolt of chained lightning leaps from the wearer's outstretched hand. Choose a primary target within 60 feet. That creature must make a DC 18 Dexterity saving throw, taking 4d10 lightning damage on a failure or half on a success. The lightning then arcs to up to three additional creatures each within 30 feet of the previous target (no creature can be struck more than once per use). Each secondary target makes the same saving throw, taking 2d10 lightning damage on a failure or half on a success.
Shackle of Storms
As a bonus action, expend 1 charge. Choose a creature you can see within 30 feet. That creature must succeed on a DC 18 Strength saving throw or become Restrained until the end of its next turn as crackling lightning manacles lock around it. A creature restrained by this effect takes 1d8 lightning damage at the start of each of its turns while restrained.
Eye of the Tyrant
As a reaction, when a creature within 60 feet of you deals damage to you or an ally you can see, expend 3 charges. A spear of pure lightning lances toward that creature. It must make a DC 18 Constitution saving throw. On a failure, it takes 5d10 lightning damage and is Stunned until the end of its next turn. On a success, it takes half damage and is not Stunned.
Thunder Ascendant
As an action, expend 4 charges. The wearer erupts in a corona of howling storm-light. Until the end of their next turn, the wearer gains a flying speed of 60 feet, immunity to lightning damage, and any creature that hits the wearer with a melee attack takes 2d10 lightning damage automatically. While this effect is active, all uses of Chain of Ruin cost 0 charges.
8 charges
Recharges 1d6+2 at dawn
DM Notes
Balance consideration: The level_band of 5–7 is intentionally aggressive for a Legendary item — at level 5, the curse's compulsion mechanic (forced movement toward bloodied enemies) can directly threaten party tactics and put the wearer in lethal danger, which is a meaningful cost. The DC 16 Wisdom save at the end of each long rest will fail roughly 40% of the time for a character with +0 Wisdom, creating persistent Frightened pressure; consider reducing the DC to 14 for classes with poor Wisdom if the campaign tone is Heroic rather than punishing. Thunder Ascendant intentionally costs 4 charges (half the pool) to prevent spamming, and its 0-charge Chain of Ruin rider only lasts one turn — verify players understand this window is tight. The Ring can be removed by a 5th-level Remove Curse rather than any casting of it, which ensures a party cleric or paladin can resolve the curse with appropriate resources. Vorthekaan's Shackle is a strong candidate for a corrupting artifact storyline: if the wearer fails the Wisdom save three times in a row, consider having Vorthekaan's voice speak to them as a roleplay hook toward a longer plot.
