Magic Items

Weapon (warhammer), legendary (requires attunement)

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.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.

This staff is carved from a single piece of an unusual, purple wood and topped with a clenched, mithral claw. The claw clutches a green dragon scale the size of a small plate engraved with the elven word for “Oblivion”. The rune glows with a pale, green light and emits wisps of choking, caustic mist. Whoever is attuned the staff is able to speak, read, and write Draconic. A description of this item can be found in the Dungeon Master’s Guide.

These parchments contain alien formula that would augment even the greatest minds. As each page is read, it dissolves into raw elemental essence. You must spend 6 downtime days to read the tome of understanding, after which the tome is destroyed and you increase your Wisdom score by 2. As an action, you automatically and immediately detect creatures afflicted by the Chaos Phage (or other slaadi poisoning) within 60 ft. of your person. As an action, you can remove these afflictions by touching the creature.

Acererak's Treasure

This amulet is fashioned from a single shard of resilient extraplanar material originating from the realm of your warlock patron. While you are wearing it, you gain the following benefits: You can use the amulet as a spellcasting focus for your warlock spells.
You can try to cast a cantrip that you don’t know. The cantrip must be on the warlock spell list, and you must make a DC 10 Intelligence (Arcana) check. If the check succeeds, you cast the spell. If the check fails, so does the spell, and the action used to cast the
spell is wasted. In either case, you can’t use this property again until you finish a long rest.

CCC-GSP-NTHR01-01 This obsidian amulet was given to Tenebris Umbra by Kothys. When attuned to this item, the essence of the Shadowfell imbued into it by Kothys turns its owner’s body deathly cold and numbs the skin it touches.

The rod is a two-foot long rod of suth-wood, carved with various alchemical symbols. (5/50 charges)
