Armor of Darkness

Forged in the aftermath of a celestial betrayal, this armor binds itself to those who tread the fine line between light and shadow.
It waits patiently in a dormant state until its chosen bearer awakens its essence.

Manifestation of Shadow

When attuned, the armor manifests in a swirl of black clouds that twist and morph into shadow-forged plates around your body.
This process takes 1 minute and can be performed as part of a short rest.
Once manifested, the armor cannot be removed unless you end the attunement.
It disappears into mist when not worn.

Artifact Properties (Choose one)

• Eclipsed Resilience. You gain resistance to necrotic and radiant damage.

• Shadow Step. As a bonus action, teleport up to 30 feet to a space you can see that’s in dim light or darkness. Usable a number of times equal to your proficiency bonus per long rest.

• Eyes of the Void. You have darkvision out to 120 feet and can see in magical darkness.

• Silent Bastion. (Fighter) You have advantage on Stealth checks in dim light or darkness. The armor imposes no Stealth disadvantage.

• Oathbreaker’s Judgment. (Paladin) Once per long rest, release a 20-foot burst of divine shadow. Creatures you choose in the area must make a DC 18 Constitution saving throw, taking 6d10 radiant and 6d10 necrotic damage (half on success). Creatures reduced to 0 HP are disintegrated.

• Dark Reservoir. (Warlock) The armor stores your willpower.
  You gain 1 additional spell slot, which must be of the highest level you can cast (counts as a Warlock spell slot).
  You regain this slot on a short rest.

• Shadow Reprisal. (Warlock) When a creature under your Hexblade’s Curse forces you to make a saving throw, you can use your reaction to gain advantage on that save. If you succeed, the cursed target takes 2d10 force damage. Usable once per short or long rest.

 

Curse — Shadowbound

Once attuned, the armor becomes bound to your soul.
If you die while wearing the armor, your body dissolves into black mist, and your soul is drawn into the Abyss.
Only a wish or true resurrection can return you — and even then, you return marked by shadow (DM’s discretion).

Half plate consists of shaped metal plates that cover most of the wearer's body. It does not include leg protection beyond simple greaves that are attached with leather straps.

Notes: blood sacrifice. It manifests in a swirl of cold, black mist. These clouds swirl around your body, silently coalescing into interlocking plates of matte obsidian and flickering shadow. , Combat, Warding, Stealth Disadvantage
