Magic Items

Wondrous item, rare
You can take a Magic action to blow this horn. In response, warrior spirits from the plane of Ysgard appear in unoccupied spaces within 60 feet of you. Each spirit uses the Berserker stat block and returns to Ysgard after 1 hour or when it drops to 0 Hit Points. The spirits look like living, breathing warriors, and they have Immunity to the Charmed and Frightened conditions. Once you use the horn, it can't be used again until 7 days have passed.

A silver horn summons 2 Berserkers. They are Friendly to you and your allies and follow your commands.

Rod, rare (requires attunement by a warlock)
2 lb.
While holding this rod, you gain a +2 bonus to spell attack rolls and to the saving throw DCs of your Warlock spells.

In addition, you can regain one spell slot as a Magic action while holding the rod. You can't use this property again until you finish a Long Rest.

Wand, uncommon
1 lb.
This wand has 7 charges. While holding it, you can expend no more than 3 charges to cast Magic Missile from it. For 1 charge, you cast the level 1 version of the spell. You can increase the spell's level by 1 for each additional charge you expend.

Regaining Charges. The wand regains 1d6 + 1 expended charges daily at dawn. If you expend the wand's last charge, roll 1d20. On a 1, the wand crumbles into ashes and is destroyed.

Weapon (Longsword), rare (requires attunement)
Martial weapon, melee weapon
3 lb.

1d8 Radiant
Finesse, Versatile (1d10)
Mastery: Sap
This item appears to be a sword hilt.

Blade of Radiance. While grasping the hilt, you can take 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 weapon functions as a Longsword with Finesse. If you are proficient with Longswords or Shortswords, you are proficient with the Sun Blade.

You gain a +2 bonus to attack rolls 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.

Sunlight. 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 take a Magic action to expand or reduce its radius of Bright Light and Dim Light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.

Heavy armor (chain mail), uncommon
55 lb.

AC 16
Mithral is a light, flexible metal. A mithral chain shirt or breastplate can be worn under normal clothes.

If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn't.

The wearer has Disadvantage on Dexterity (Stealth) checks.

If the wearer has a Strength score lower than 13, their speed is reduced by 10 feet.

Wondrous item, rare (requires attunement)
While wearing this cloak, you have Advantage on Dexterity (Stealth) checks. In an area of Dim Light or Darkness, you can grip the edges of the cloak and use it to gain a Fly Speed of 40 feet. If you ever fail to grip the cloak's edges while flying in this way, or if you are no longer in Dim Light or Darkness, you lose this Fly Speed.

While wearing the cloak in an area of Dim Light or Darkness, you can cast Polymorph on yourself, shape-shifting into a Bat. While in that form, you retain your Intelligence, Wisdom, and Charisma scores. The cloak can't be used this way again until the next dawn.

Weapon, uncommon
Martial weapon, melee weapon
6 lb.

1d10 Slashing
Heavy, Reach, Two‑Handed
Mastery: Graze
You have a +1 bonus to attack and damage rolls made with this magic weapon.

Heavy. You have Disadvantage on attack rolls with a Heavy weapon if it's a Melee weapon and your Strength score isn't at least 13 or if it's a Ranged weapon and your Dexterity score isn't at least 13.

Reach. A Reach weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for Opportunity Attacks with it.

Two-Handed. A Two-Handed weapon requires two hands when you attack with it.

Mastery: Graze. If your attack roll with this weapon misses a creature, you can deal damage to that creature equal to the ability modifier you used to make the attack roll. This damage is the same type dealt by the weapon, and the damage can be increased only by increasing the ability modifier.

Wondrous item, uncommon
As a Magic action, you can open or close this bottle.

Opening the bottle causes thick smoke to billow out, forming a cloud that fills a 60-foot Emanation originating from the bottle. The area within the smoke is Heavily Obscured.

Each minute the bottle remains open, the size of the Emanation increases by 10 feet until it reaches its maximum size of 120 feet.

Closing the bottle causes the cloud to become fixed in place until it disperses after 10 minutes. A strong wind (such as that created by the Gust of Wind spell) disperses the cloud after 1 minute.

Bloodshed Greatsword, Weapon (Greatsword), Very Rare (Requires Attunement)

Look: A razor-straight greatsword of black-iron glass (like frozen obsidian) with faint red “heat lines” inside the metal. The carnelian in the hilt is a sealed infernal lens engraved with Mephistopheles’ blood rune—more contract than gem.

Baseline (Con mod to damage):
Not “you’re sturdy so you hit harder,” but: your vitality is collateral—the sword’s edge is fed by the Champion’s endurance. The blade “recognizes” a resilient body as worthy fuel.

Invoking the Rune: The Blood Mantle (your key ask)

When you invoke the rune, it’s not just light—it's a sanctioned infernal phenomenon:

Invocation narration (universal):

"The rune snaps open like a clause being read aloud. Your heartbeat stutters once—then answers. A pressurized burst of blood erupts from pores, scars, and the corners of your eyes, but it doesn’t fall. It whips outward in a tight orbit, dragged into a spiral around the blade like a red comet’s tail. The sword hums, satisfied—precision purchased."

Scaling the “amount depends on Hit Dice spent”

Use these descriptions keyed to how many Hit Dice are rolled/spent.

For the attack roll boost (spend 1 HD):

A single arterial ribbon lashes out of your chest/forearms and braids around the edge.

Sound: a wet snap followed by a clean, glassy ring as it “hardens.”

Visual: crimson light “ticks” along the blade like a metronome.

If the hit lands and you add damage with more HD:

1 HD

The blood mantle thickens into a second coil. Droplets stop falling and become tiny barbed motes that orbit the edge like red shrapnel held in place by will alone.

2–4 HD

The coils compress into layered plates—a lacquered, ceremonial armor along the fuller and edge. The blade looks wider without changing size, like reality is being persuaded to give it more surface to cut with.

5–7 HD

The plating fractures into a segmented halo of crimson ribs that “click” into alignment with each heartbeat. Each segment briefly shows infernal glyphs—contract-letters that flash and vanish as the sword bites.

8–10 HD

The blood becomes a howling helix, shaping a phantom greatsword silhouette around the real one. Every swing leaves a crimson afterimage that lags half a heartbeat behind, as if the strike is being co-signed by something larger than you.

11–13 HD

The phantom silhouette gains weight and detail: a second edge, jagged and regal, like a crowned executioner’s blade made of living ink. The air around the sword warps with heatless pressure; nearby droplets and dust get dragged into orbit, forming a brief crimson corona.

14–16 HD

The mantle achieves its final clause: the blood erupts into a cathedral of motion—spiraling spines, plates, and helixes that assemble into a towering, translucent infernal greatblade around yours. For an instant, it’s as if Mephistopheles’ own hand is over yours—your strike arrives in two layers: the steel, then the verdict. The afterimage doesn’t fade so much as snap shut, like a contract sealed.

Optional Mephistopheles flair (pure narration):

The blood briefly forms infernal script midair—contract-letters that dissolve into sparks.

A faint voice like distant opera: “Worthy.” (or the user hears their own name spoken perfectly)

“Champion of Mephistopheles” Thematic Hooks (no mechanical changes)

The Worthiness Test

The sword subtly judges:

If you hesitate, the rune’s glow dims like disappointment.

If you commit, it purrs—like a patron pleased with a decisive champion.

Charm

You can speak and understand all languages, you gain proficiency in the Deception and Persuasion skills, and you can add double your normal proficiency bonus when using those skills. This charm vanishes from you when you die.

Rod, legendary (requires attunement)

This rod has a flanged head, and it functions as a magic mace that grants a +3 bonus to attack and damage rolls made with it. The rod has properties associated with six different buttons that are set in a row along the haft. It has three other properties as well, detailed below.

Six Buttons. You can press one of the rod’s six buttons as a bonus action. A button’s effect lasts until you push a different button or until you push the same button again, which causes the rod to revert to its normal form.

If you press button 1, the rod becomes a flame tongue, as a fiery blade sprouts from the end opposite the rod’s flanged head (you choose the type of sword).

If you press button 2, the rod’s flanged head folds down and two crescent-shaped blades spring out, transforming the rod into a magic battleaxe that grants a +3 bonus to attack and damage rolls made with it.

If you press button 3, the rod’s flanged head folds down, a spear point springs from the rod’s tip, and the rod’s handle lengthens into a 6-foot haft, transforming the rod into a magic spear that grants a +3 bonus to attack and damage rolls made with it.

If you press button 4, the rod transforms into a climbing pole up to 50 feet long, as you specify. In surfaces as hard as granite, a spike at the bottom and three hooks at the top anchor the pole. Horizontal bars 3 inches long fold out from the sides, 1 foot apart, forming a ladder. The pole can bear up to 4,000 pounds. More weight or lack of solid anchoring causes the rod to revert to its normal form.

If you press button 5, the rod transforms into a handheld battering ram and grants its user a +10 bonus to Strength checks made to break through doors, barricades, and other barriers.

If you press button 6, the rod assumes or remains in its normal form and indicates magnetic north. (Nothing happens if this function of the rod is used in a location that has no magnetic north.) The rod also gives you knowledge of your approximate depth beneath the ground or your height above it.

Drain Life. When you hit a creature with a melee attack using the rod, you can force the target to make a DC 17 Constitution saving throw. On a failure, the target takes an extra 4d6 necrotic damage, and you regain a number of hit points equal to half that necrotic damage. This property can’t be used again until the next dawn.

Paralyze. When you hit a creature with a melee attack using the rod, you can force the target to make a DC 17 Strength saving throw. On a failure, the target is paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success. This property can’t be used again until the next dawn.

Terrify. While holding the rod, you can use an action to force each creature you can see within 30 feet of you to make a DC 17 Wisdom saving throw. On a failure, a target is frightened of you for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. This property can’t be used again until the next dawn.

Only Asmodeus recipient of Mahadis Deal and its direct descendants can attune to this item.

Any humanoid killed by an attack made with this weapon has its soul funneled into the River Styx, where it's reborn instantly as a lemure devil.

Thrown. If a weapon has the Thrown property, you can throw the weapon to make a ranged attack, and you can draw that weapon as part of the attack. If the weapon is a Melee weapon, use the same ability modifier for the attack and damage rolls that you use for a melee attack with that weapon.

Mastery: Slow. If you hit a creature with this weapon and deal damage to it, you can reduce its Speed by 10 feet until the start of your next turn. If the creature is hit more than once by weapons that have this property, the Speed reduction doesn't exceed 10 feet.

Ring, rare (requires attunement)
While wearing this ring, you can take a Magic action to gain X-ray vision with a range of 30 feet for 1 minute. To you, solid objects within that radius appear transparent and don't prevent light from passing through them. The vision can penetrate 1 foot of stone, 1 inch of common metal, or up to 3 feet of wood or dirt. Thicker substances or a thin sheet of lead block the vision.
