A d100 Kull era Atlantian Artifacts table for Castles & Crusades rpg Campaign Set in Kull's Thurian Age

 

Here is a d100 Atlantean Artifacts table tailored for a Castles & Crusades campaign set in Robert E. Howard’s pre-cataclysmic Thurian Age (the era of Kull of Atlantis).

In this primordial era, Atlantis is not yet a sunken utopia; it is a rugged, sea-beaten continent inhabited by savage, tribal barbarians. Magic is rare, dark, and deeply tied to elder horrors, Serpent Men, and alien alchemy. These artifacts reflect that gritty, "Sword & Sorcery" tone, utilizing Castles & Crusades mechanics (Attribute Checks, Prime Attributes, and saving throws).

D100 Atlantean Artifacts Table

d100	Artifact	Brief Description & C&C Mechanics
01–05	Tiger-Valley War Club	A heavy stone-headed club bound in mammoth sinew. It functions as a +2 war club. Once per day, the wielder can unleash a roar requiring all enemies within 30 ft. to pass a Charisma save or be shaken (-2 to hit and AC) for 1d6 rounds.
06–10	The Obsidian Mirror of Tuzun Thune	A polished black volcanic glass mirror. A spellcaster looking into it can cast Scrying at will, but must make a Wisdom save (CL 6) each time or lose 1 point of Wisdom permanently as their soul is slowly drawn into the mirror's infinite depth.
11–15	Scale of the First Serpent	A large, iridescent green scale used as a buckler (+1 AC). It grants the user complete immunity to all natural and magical poisons. If a Serpent Man looks at the shield, they must make a Charisma save or be forced into their true, non-humanoid snake form.
16–20	Sea-Mountain Harpoon	A barbed +1 spear carved from the rib of a prehistoric leviathan. When thrown, it automatically returns to the wielder’s hand. On a critical hit against a creature with the aquatic subtype, it deals triple damage.
21–25	Alchemical Fire-Beads of Lemuria	A pouch of 1d6+1 cold, metallic red glass beads. When thrown (range 30 ft.), they burst. Treat as Fireball (5d6 fire damage, Dexterity save for half) but the fire burns underwater.
26–30	Mask of the Great Ape	A dried gorilla leather mask. When worn, the user gains +4 to Strength and Constitution but drops their Intelligence to 3. They gain a climb speed of 30 ft. and can fight for 1d4 rounds after reaching 0 hit points before dying.
31–35	The Iron Collar of the Galley-Slave	A rusted iron collar. When locked around a humanoid's neck, they are completely immune to exhaustion, sleep, and fear, but cannot disobey any direct verbal command from the key-holder.
36–40	Vial of Black Lotus Elixir	A single dose of shimmering black liquid. Drinking it grants the user the ability to cast Contact Other Plane to speak with the Great Old Ones. The user must make a Constitution save or permanently lose 1d4 points of Wisdom from the maddening revelations.
41–45	The Golden Skull of Rotath	A solid gold human skull inscribed with ancient Lemurian runes. It acts as a spell focus; any necromancy spell cast while holding it is cast at +2 Caster Level. It whispers secrets of the pre-human world to its holder during sleep.
42–50	The Jade Tooth of Valusia	A thumb-sized chunk of carved green jade. When pressed against a poison or curse, it absorbs it completely, turning pitch black. It can absorb up to 3 curses or lethal poisons before shattering.
51–55	Horn of the Tiger-Beast	A curved horn that can be blown once per day. It summons 1d4 saber-toothed tigers that obey the blower's mental commands for 1 hour or until slain, after which they dissolve into sea foam.
56–60	Ring of the Red Shadow	A copper band set with a raw ruby. Once per day, the wearer can step into a shadow and emerge from any other shadow within 100 feet (as Dimension Door).
61–65	Slayer’s Flint Dagger	A serrated knife made of gray flint. It acts as a +1 dagger but ignores all forms of magical damage reduction or physical armor bonuses from spells (like Shield or Mage Armor). It cuts purely through the physical body.
66–70	The Tabard of the Topaz Throne	A heavy silk vestment dyed the brilliant yellow of Valusia's royal color. The wearer gains a +3 bonus to all Charisma attribute checks and saving throws. However, they suffer a -2 penalty to Wisdom checks due to a lingering, arrogant paranoia.
71–75	The Whispering Shell	A giant spiral conch. Listening to it allows the user to understand any spoken language for 1 hour. There is a 5% chance the shell instead fills the user's mind with the deafening, maddening sounds of the roaring Pre-Cataclysmic ocean (stunned for 1d4 rounds).
76–80	Blood-Stone of Grondar	A dark red gem that must be pressed into an open wound to activate. It immediately heals 3d8+3 hit points. However, the user must immediately make a Constitution save or contract a wasting blood sickness that prevents natural healing until cured by magic.
81–85	The Pictish Tracker’s Fetish	A bundle of dried bones, feathers, and dried wolf eyes. When held, it grants the user the Ranger's Track ability (or a +5 bonus if the user is already a Ranger/Tracker).
86–90	The Silver Key of Kamelia	A delicately crafted key made of pure, un-tarnished starlight-silver. It can unlock any non-magical lock instantly. If used on a magically sealed door, it triggers a Dexterity check (CL of the seal) to bypass without setting off traps.
91–95	Crown of the First Barbarian	A simple band of hammered bronze and dire-wolf fangs. The wearer is entirely immune to mind-affecting magic, charms, and illusions. They rely entirely on raw, unyielding instinct.
96–00	The Great Greatsword of Valusian Kings	A massive, two-handed sword of stellar iron. It functions as a +3 greatsword. On a successful hit, it deals an extra 1d6 points of cold damage. Once per week, the wielder can cleave the air to tear open a temporary rift to the void, banishing one extraplanar creature hit by the blade (Charisma save to resist).

How to Introduce these Artifacts in Castles & Crusades

• No "Identify" Spell: In a Kull-era campaign, players shouldn't simply cast Identify to learn these attributes. They must translate dead languages, consult ancient Pictish shamans, or experiment—often at great risk.

• The Price of Magic: These items are powerful but primitive. Many carry curses, psychological burdens, or draw the attention of ancient entities like the Serpent Men or Thulsa Doom. Use the Castle Keeper (CK) active-threat mechanics to make players weigh the benefits of using them.

D100 Primeval Monster & Hazard Encounters

The wilderness of the Kull era is untamed, featuring prehistoric beasts, dying elder races, and cosmic horrors that predate humanity.

d100	Encounter	Description & Threat Profile
01–15	The Serpent Man Infiltrator	A single assassin disguised as a trusted ally or local noble. Tactics: It waits for a moment of vulnerability to strike with a poisoned dagger (3d6 damage + Lethal Poison). It will attempt to flee using illusion magic if discovered.
16–30	Pack of Ghost-Swamp Hyenas (3d6)	Emaciated, pale-furred beasts that hunt in the mist-shrouded lowlands. Tactics: They use pack tactics to flank characters (DM+1 to attack when outnumbering a target). Their eerie, mocking laughter forces a SOC/Sanity check to avoid being Shaken for the first round of combat.
31–45	Prehistoric Dire Ape	A massive, silver-backed behemoth standing 4 meters tall. Tactics: Aggressive and territorial. It uses brawling attacks (3d6+2 damage) and will attempt to grab a character to fling them into terrain or crush them. It has an Armor rating of 3.
46–60	The Living Slime of Commoria	An amorphous, translucent grey mass sliding along dungeon floors or ancient ruins. Tactics: Completely immune to piercing and slashing weapons. It attacks by engulfing targets, dealing 2d6 acid damage per round to armor and flesh alike. Vulnerable only to fire and sorcery.
61–75	Valusian Blood-Bat Swarm	A cloud of leather-winged, red-eyed pests filling a corridor or jungle canopy. Tactics: They attack as a single entity, targeting all characters in an area. They deal low damage (1d6) but cause continuous bleeding (1 damage/round) until a First Aid check is made.
76–85	The Shadow of the Elder Dark	An incorporeal horror summoned by ancient, forgotten rituals. Tactics: It cannot be harmed by mundane weapons. It attacks a character's mind and soul rather than their physical body, forcing an INT check each round. Failure inflicts 1d6 points of permanent Sanity damage.
86–95	Ancient Atlantean Automaton	A towering guardian made of bronze and stone, still functioning after millennia. Tactics: Armed with a massive stone blade (4d6 damage) and boasting an Armor rating of 6. It moves slowly but relentlessly, pursuing its designated targets until destroyed.
96–00	The Thing from the Stars	A cosmic aberration that has slipped through a tear in reality. Tactics: Its sheer presence forces a Sanity check (DM-3) for all who look upon it. It attacks with writhing tentacles (3d6 damage, 4 attacks per round) and can warp space to teleport short distances.

The pre-cataclysmic world of King Kull’s Atlantis is a brutal, sun-drenched, and blood-soaked era where civilization is a thin veneer over primeval chaos. In Sword of Cepheus 2nd Edition, these elements focus heavily on lethal physical stakes, ancient sorcery, and high-risk exploration. This blog post picks right up from D100 Kull Era Atlantean Relics and Monster Encounter Tables For A Sword & Sorcery Sword of Cepheus 2nd edition

Here are the custom d100 tables for Atlantean relics and monster encounters, tailored to the gritty, career-based mechanics of Cepheus.

D100 Atlantean Relics & Sorcerous Artifacts

These relics represent the peak of pre-cataclysmic forging and forbidden alchemy. In Sword of Cepheus, many of these carry hefty costs to a character's Sanity or physical attributes.

d100	Relic	Mechanics & Effects (Sword of Cepheus 2E)
01–10	Valusian Serpent Glass	A heavy, obsidian-framed mirror. When a humanoid passes in front of it, the glass reflects their true form. Effect: Instantly reveals shape-shifted Serpent Men, bypassing any illusion or magical disguise. Seeing the true horror requires a SOC Check (DM-2) to avoid a temporary 1-point loss in Social Standing due to sheer shock.
11–20	Heart of the Moon Gem	A flawless, milky-white sapphire that pulses with a cold light. Effect: Can be crushed as a minor action. It instantly restores 2d6 points across wounded physical characteristics (STR/DEX/END). However, the user’s eyes turn solid white for 24 hours, giving a DM-2 to all visual Recon checks in daylight.
21–30	Lemurian Brass Lotus	A mechanical, pocket-sized brass flower. When wound, it emits a faint, hypnotic chime. Effect: Targets within 5 meters must make an END check (DM-1) or fall into a deep stupor for 1d6 rounds. It draws heavily on the user's life force, dealing 1 point of temporary STR damage per use.
31–40	Obsidian Shamshir of Grond	A heavy, dark-glass blade that never dulls. It functions as a Broadsword (3d6 damage) but uses the wielder's raw hatred to strike. Effect: Grants DM+2 to Melee (Blades) checks against sorcerers and supernatural beasts. On a natural combat roll of 2, the blade chips, dealing 1d6 damage directly to the wielder's END.
41–50	Thurian Iron Torc	A thick, unadorned neck ring worn by ancient warlords. Effect: Grants the wearer a +2 Armor rating against all physical attacks and makes them completely immune to mundane poisons. However, it cannot be removed unless the wearer enters a state of Near-Death (any characteristic reduced to 0).
51–60	Urn of the Silent Wind	A sealed clay urn etched with pre-human glyphs. Effect: Opening the urn releases a localized, choking vacuum. For 3 rounds, no sound can be made, and no verbal spells can be cast within a 10-meter radius. Characters inside must make an END check each round or suffer 1d6 damage from asphyxiation.
61–70	Scroll of the Seven Sunken Cities	A tattered, water-resistant vellum map. Effect: Grants a permanent DM+2 to all Navigation and Survival checks when exploring ruins or wilderness. Reading the scroll requires an INT check (DM-2); failure results in a permanent 1-point loss of Sanity as the reader glimpses the true timeline of the world.
71–80	Jade Mask of the Ever-Living	A terrifying, stylized green jade mask. Effect: While worn, the user does not age, bleed, or feel pain. They gain +3 to END checks to resist injury. The cost is severe: while wearing the mask, the user cannot heal naturally, and any magical healing applied to them is halved.
81–90	Blood-Forged Ring of Atlantis	A ring made of an unknown red alloy that bonds to the wearer's skin. Effect: Allows the wearer to cast any sorcerous spell they know without spending Life Force/Mana. Instead, the spell drains 1 point of STR per spell level. The STR recovers at a rate of 1 point per full day of complete rest.
91–00	The Skull of Commoria	The silver-plated skull of an ancient king. Effect: Once per day, the wielder can ask the skull one question about local history, geography, or defensive traps. The skull answers truthfully but demands a sacrifice of blood equivalent to 2d6 damage dealt to a thrall or companion.
