Tips for Inner Earth in C&C

• Encumbrance Matters: In the deep, every pound of gear counts. Use the Strength attribute to strictly enforce carry limits.

• Light Sources: Torches and lanterns are the party’s lifeline. Keep track of oil and duration.

• The Check System: Remember that Castles & Crusades uses the SIEGE Engine (d20 + level + bonus vs. 12 or 18). For Inner Earth, environmental hazards are usually Physical (Str, Dex, Con), while navigating or spotting traps are Mental (Int, Wis, Cha).
  
  

Here is a formidable Black Sorcerer designed for Castles & Crusades. In the context of Inner Earth, "Black Sorcery" usually implies a practitioner who draws power from the crushing pressure of the deep earth and the void between the stars.

Xul’Abas the Ossified

Class: Wizard (Necromancer/Earth Focus)

Level: 9

Alignment: Lawful Evil

Prime Attributes: Intelligence, Wisdom, Dexterity

Background

Xul’Abas was once a surface scholar who became obsessed with the "Geological Memory" of the world. He traveled into the Infranight to find the Lithic Heart, a legendary artifact said to be the literal ego of the earth. He found it, but the exposure "ossified" him—his skin has become a translucent, marble-like substance, and his blood has slowed to the consistency of cooling lava. He now rules a small fiefdom of Ghouls and Earth Elementals, seeking to turn the entire world into a static, unchanging tomb of stone.

---

Attributes & Stats

• HP: 32

• AC: 16 (DEX bonus + Bracers of Defense)

• Move: 20 ft. (Due to his stone-like skin)

• Attacks: Staff of the Cavern (+1, $1d6+1$) or Dagger ($1d4$)

• Saving Throws: * Mental: 18+ (Prime: Intelligence/Wisdom)

  • Physical: 12+ (Non-Prime: Strength/Constitution/Charisma)

Special Abilities

• Ossified Skin: Xul’Abas has Damage Reduction (DR) 3 against non-magical piercing and slashing weapons.

• Earth Glide: Once per day, he can pass through solid stone as if it were water for 1 turn.

• Gaze of Stasis: Once per day, Xul’Abas can force a target to make a Wisdom (Mental) save or be affected as per the Slow spell for 5 rounds.

---

Prepared Spells

• 3rd Level: Fireball (Explosive Gas), Dispel Magic, Haste

• 4th Level: Wall of Ice (Wall of Quartz), Stoneskin

• 5th Level: Cloudkill (Sulfuric Vapors)

---

Roleplaying Xul’Abas

Voice/Demeanor: His voice sounds like grinding tectonic plates—slow, deep, and vibrating in the listeners' chests. He does not blink. He finds the rapid breathing and "wet" nature of surface dwellers repulsive.

Tactics: Xul’Abas never fights fair. He prefers to use Web or Wall of Quartz to split the party, then targets the most heavily armored foe with Cloudkill. He views himself as an architect of eternity; he doesn't want to kill the PCs so much as he wants to "preserve" them as statues in his gallery.

Plot Hooks

• The Missing Heir: A noble's child was taken by "pale shadows." They are currently being held in Xul'Abas's sanctum, undergoing the ritual to become an Ossified servant.

• The Tremor Key: The party needs a specific key to open a mountain vault. Xul'Abas has integrated that key into his own stone ribcage.

• The Geode Pact: Xul'Abas offers the party safe passage through the Deep if they can retrieve a "Heart of Magma" from a nearby fire giant forge.
  

  In Castles & Crusades, the Ossified Ghoul is a more durable and sluggish variant of the standard ghoul. Xul’Abas has infused their necrotic flesh with minerals and calcified dust, turning them into living (or unliving) statues of hunger.

  ---

  Ossified Ghoul (Undead)
  

  

  
  
  

  These creatures look like standard ghouls, but their skin is a mottled, grey-white crust that cracks when they move, revealing dark, tar-like ichor beneath. Their claws are not bone, but jagged obsidian shards.

  Stat	Value
  Hit Dice	3d8 (Large HD)
  Armor Class	16
  Move	20 ft.
  Attacks	2 Claws ($1d4$), 1 Bite ($1d6$)
  Special	Paralysis, Calcifying Bite, Undead, Resistance
  Saves	Physical (Prime)
  Alignment	Lawful Evil
  Challenge Level	4

  Special Abilities

  • Resistance: Because of their stone-like hide, Ossified Ghouls take half damage from piercing and slashing weapons. Bludgeoning weapons deal normal damage.

  • Paralysis: Anyone struck by an Ossified Ghoul’s claw or bite must succeed on a Constitution (Physical) save or be paralyzed for $3d6$ minutes. (Elves are immune to this effect).

  • Calcifying Bite: If a target is bitten, they must make an additional Strength (Physical) save. On a failure, their joints begin to stiffen with mineral deposits. The victim suffers a –2 penalty to Dexterity and –10ft to movement. This effect lasts until a Remove Curse or Restoration is cast, or until the victim spends 24 hours in a warm, sulfur-free environment.

  • Undead: Immune to mind-influencing effects, poison, and sleep. They can be turned by a Cleric as a 4 HD undead due to their earth-infused resilience.

  ---

  Tactics and Behavior

  Unlike common ghouls that rush forward in a frenzy, Ossified Ghouls move with a rhythmic, clacking deliberate pace. Xul’Abas often hides them in plain sight—they stand perfectly still in alcoves, masquerading as poorly carved statues until a "living" presence triggers their hunger.

  In combat, they act as a "wall." While Xul’Abas casts spells from the rear, 3 or 4 Ossified Ghouls will block a 10-foot-wide tunnel. Their high AC and resistances make them very difficult for low-level Fighters to cut through quickly.

  The Cracking Sound: A party can detect them with a Wisdom (Mental) check (CL 3) if they listen closely; the ghouls emit a faint scritch-clack sound as their mineral-heavy lungs expand and contract.

  ---

  Encounter Idea: The Petrified Guard

  The Setup: The party enters a hallway lined with 6 statues of ancient warriors.

  The Twist: Two are actual statues; four are Ossified Ghouls. Xul’Abas has cast Darkness on the ceiling. When the party reaches the midpoint, the Ghouls drop from the shadows or step off their plinths, attempting to paralyze the party's "squishier" members to be dragged away for Xul'Abas's collection.

The Echoing Sepulcher is not a tomb in the traditional sense, but a massive, hollowed-out geode suspended over a bottomless rift. In Castles & Crusades, this location serves as a "mega-dungeon" node—a place where sound, light, and gravity behave according to the whims of Xul’Abas.

---

The Echoing Sepulcher

The Visuals: A Pale Cathedral

The walls of the Sepulcher are composed of milky quartz and jagged selenite crystals that reach up like frozen ribs toward a ceiling lost in gloom. Everything is coated in a fine, white mineral dust that mufflers footsteps but carries whispers for hundreds of yards.

Faint, rhythmic thumping—the "heartbeat" of the earth—vibrates through the floor, requiring a Constitution (Physical) check for anyone trying to sleep here; failure means they gain no hit points or spells back due to the unsettling vibrations.

---

Key Features & Zones

1. The Acoustic Lens (The Entrance)

The entry tunnel is shaped like a funnel. Because of the unique geometry, a whisper at the entrance can be heard clearly by Xul’Abas in the central sanctum.

• The Hazard: Characters must make a Dexterity (Physical) check to move silently. However, the CL (Challenge Level) increases by +1 for every person in the party, as the cave "gathers" the sound of their gear clanking.

2. The Gallery of the Still

A wide hall lined with hundreds of "statues." Some are genuine carvings, but many are former adventurers and cavern denizens coated in the same calcified crust as the Ossified Ghouls.

• The Danger: 1-in-6 statues is actually a dormant Ghoul. If the party uses a light source brighter than a candle, the reflections off the quartz walls create a "Dazzle" effect, imposing a –2 penalty to all Wisdom (Mental) checks to spot movement.

3. The Lithic Altar (The Sanctum)

The center of the Sepulcher is a platform of solid obsidian floating over a pit of sulfuric steam. This is where Xul’Abas conducts his "Ossification Rituals."

• The Environment: The air here is thin. Spellcasters must succeed on a Strength (Physical) check to provide the somatic components of spells, as the air feels as heavy as water.

4. The Weeping Walls

In the lower reaches, water saturated with lime drips constantly, forming stalactites at an impossible speed.

• The Loot: Within the hardening lime are the "treasures" of those Xul’Abas has transformed—magic rings, coins, and a +2 Shield are visible, but they must be hacked out of the stone (taking 1d4 turns and making immense noise).

Sensory Table: The Atmosphere

Sense	Experience
Sight	Pale whites, translucent grays, and the occasional spark of purple amethyst.
Sound	High-pitched "singing" from the wind through the crystals; the grinding of stone.
Smell	Chalky, dry, and metallic—like a blacksmith's shop after the forge has cooled.
Touch	A constant, low-frequency vibration that makes teeth ache and armor rattle.

---

SIEGE Engine Challenges in the Sepulcher

• Navigating the Crystal Spires: Dexterity (Physical) to climb the slick, glass-like surfaces. (CL 4)

• Resisting the Crushing Gloom: Wisdom (Mental) save or become Shaken (–1 to all rolls) by the claustrophobic weight of the miles of rock above. (CL 2)

• Deciphering the Wall Runes: Intelligence (Mental) to realize the etchings on the walls are actually a map of the surrounding Inner Earth tunnels. (CL 6)

In a Castles & Crusades Sword & Sorcery campaign, treasure should feel ancient, heavy, and often a bit dangerous. Gold is common, but true "treasure" often consists of ivory, strange gems, and artifacts with a history.

Below is a d100 table for Sword & Sorcery treasures.

Handling Treasure in C&C

In a gritty Sword & Sorcery setting, Encumbrance is the primary limit on wealth.

• The Weight of Wealth: 10 gold pieces weigh 1 pound. A chest of 2,000gp (Roll 92-94) weighs 200 lbs. The party will need pack animals or hirelings to get it out of the Inner Earth.

• The Squalor Rule: If players spend their gold on carousing, wine, and high living in cities, give them 1:1 Experience Points for the gold spent. This encourages the "easy come, easy go" cycle of the genre.

In a Castles & Crusades Sword & Sorcery campaign, the "Carousing" mechanic is essential. It represents the pulp fantasy cycle of finding a fortune, descending into a city's underworld, and waking up days later with no money but a lot of new problems (and XP).

When the party returns to a surface city or a massive subterranean trade-hub like a Duergar Deep-Port, they can spend their gold on "Carousing." For every 1gp spent on debauchery, they gain 1 XP.

---

The Carousing Table (d20)

After declaring how much gold you are spending, roll 1d20 to see how the "festivities" ended.

d20	Result	Outcome
1	The Dark Cell	You wake up in a dungeon. You’ve been stripped of all equipment. You are charged with a crime you (probably) committed.
2-3	Gambling Debt	You lost more than you had. You owe a local crime lord or a crooked merchant 2d6 x 100gp. They expect payment or a "favor."
4-5	Magical Blight	You drank something strange. You are under the effect of a random 1st-level curse or have turned a strange color.
6-7	The Wrong Crowd	You wake up in a different city or a deeper layer of the Earth with no memory of how you got there.
8-9	Brawl Survivor	You started a riot. You have –2 to Charisma checks in this city until you pay for the damages ($3d6 \times 10$ gp).
10-11	New Rival	You insulted a high-ranking official or a rival adventurer. They are now actively plotting against you.
12-13	Fuzzy Memory	You woke up with a strange map tattooed on your arm. It leads to a "guaranteed" treasure... or a trap.
14-15	Local Hero	You were the life of the party! You gain a +1 bonus to Charisma checks in this specific town for one month.
16-17	The Romantic Interest	You are now "engaged" to someone influential. They (or their family) take this very seriously.
18-19	Deep Connections	You befriended a master thief or black-market dealer. They will sell you "restricted" items at a 10% discount.
20	Inner Earth Legend	Stories of your exploits have spread. Gain double XP for the gold spent, and an NPC offers you a high-paying contract.

Carousing Mishap: The "Blackout" Side-Quest

If a player rolls a 1 (The Dark Cell) or a 2-3 (Gambling Debt), don't just take their gold—give them a way out.

• The Jailbreak: The party must break their friend out of a stone-prison guarded by 1d6 Veteran Guards (HD 2).

• The Debt Collection: The merchant demands the party go back into the Echoing Sepulcher to retrieve a specific crystal "Xul’Abas keeps in his private chambers."

Managing the "Squalor" Cycle

To keep the game moving, use the SIEGE Engine for carousing-related social checks:

• Intelligence (Mental): To remember a piece of vital info overheard while drunk.

• Charisma (Mental): To talk your way out of a city fine.

• Constitution (Physical): To see if you can handle the "Deep-Earth Ale" without taking a permanent penalty to your next day's rolls.
