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.

Matalotok, the Frost Father, is an ancient hammer fashioned by Thrym, the god of frost giants. The favored weapon of the demon lord Kostchtchie, Matalotok is frigid to the touch and wreathed in mist.

You are immune to cold damage while holding Matalotok. Whenever it deals damage to a creature, the hammer radiates a burst of intense cold in a 30-foot-radius sphere. Each creature in that area takes 10 (3d6) cold damage.

Versatile. A Versatile weapon can be used with one or two hands. A damage value in parentheses appears with the property. The weapon deals that damage when used with two hands to make a melee attack.

Mastery: Push. If you hit a creature with this weapon, you can push the creature up to 10 feet straight away from yourself if it is Large or smaller.

Medium armor (scale mail), very rare (requires attunement)
45 lb.

AC 14 + Dex (max 2)
Dragon Scale Mail is made of the scales of one kind of dragon. Sometimes dragons collect their cast-off scales and gift them. Other times, hunters carefully preserve the hide of a dead dragon. In either case, Dragon Scale Mail is highly valued.

Additionally, you can focus your senses as a Magic action to discern the distance and direction to the closest gold dragon within 30 miles of yourself. This action can't be used again until the next dawn.

Wondrous item, very rare (requires attunement by a creature that can speak Infernal)
This bulky, eyeless helmet is made for a pit fiend but magically resizes to fit the heads of other wearers.

While wearing the helm, you can see out of it as though you weren't wearing it. In addition, you know the exact location and type of all devils within 1,000 feet of you. You can telepathically communicate with a devil within range, or you can broadcast your thoughts to all devils within range. The devils receiving your broadcasted thoughts have no special means of replying to them.

The helm has 3 charges. As an action, you can expend 1 charge to cast dominate monster (save DC 21), which affects devils only. (The spell fails and the charge is wasted if you target any creature that's not a devil.) If a devil can see you when you cast this spell on it, the devil knows you tried to charm it. The helm regains all its charges 24 hours after its last charge is expended.

If you are not a devil, using the helm's dominate monster property in the Nine Hells has a 20 percent chance of attracting a narzugon, which arrives on the back of a nightmare mount in 1d4 hours. The narzugon tries to recover the helm, killing you if necessary to obtain it. If it gets the helm, the narzugon tries to deliver it to its infernal master.

Ring, very rare (requires attunement)
While wearing this ring, you can cast Telekinesis from 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.

This Silvered Greatsword once belonged to a Githyanki Knight.

Wondrous item, very rare (requires attunement)
This hell-forged battle standard is made of infernal iron and fitted with a small, unopenable cage containing a quasit. The trapped quasit is incapacitated, and its cage has AC 19, 10 hit points, and immunity to all types of damage except force damage. If killed or somehow released, the quasit disappears in a cloud of smoke, and a new one appears in the cage, provided the cage is intact.

While you hold the banner, your weapon attacks and those of all allied creatures within 300 feet of you count as magical for the purposes of overcoming damage immunities and resistances.

Shield (Shield), Very Rare (Requires Attunement)
6 lb.

AC +2
While holding this Shield, you can take a Bonus Action to cause it to animate. The Shield leaps into the air and hovers in your space to protect you as if you were wielding it, leaving your hands free. The Shield remains animate for 1 minute, until you take a Bonus Action to end this effect, or until you die or have the Incapacitated condition, at which point the Shield falls to the ground or into your hand if you have one free.

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.

Ring, rare
You have Resistance to Fire damage while wearing this ring. The ring is set with garnet.

Wondrous item, rare (requires attunement)
While you wear both of these steel gauntlets, any non-magical weapon you grasp with either gauntlet is treated as a magic weapon. As a bonus action, you can use the gauntlets to cause magical flames to envelop one or two melee weapons in your grasp. Each flaming weapon deals an extra 1d6 fire damage on a hit. The flames last until you sheath or let go of either weapon. Once used, this property can't be used again until the next dawn.

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.
