Floor Brackets: 1-5, 6-10, and 11-15 Progression
Understanding enemy scaling and hazard tiers as you descend into the abyssal underworld.
The Catacombs are divided into three distinct difficulty tiers, punctuated by locked shortcut gates that remain permanently open once unlocked from the inside. Entering the dungeon without adequate stamina food or healing potions is suicide.
Floors 1 through 5 act as a training ground against Green Slimes and Vampire Bats. Floors 6 through 10 introduce armored Skeleton Spearmen that block frontal attacks, while Floors 11 through 15 unleash ethereal Shadow Wraiths that teleport behind you and fire soul-draining projectiles.
| Floor Bracket | Primary Monsters | Key Mineral Drops | Recommended Weapon / Armor Tier |
|---|---|---|---|
| Floors 1 to 5 | Green/Blue Slimes, Cave Bats | Bog Iron, Coal Chunks | Rusty / Iron Sword + Cloth Tunic |
| Floors 6 to 10 | Skeleton Swordsmen, Spearmen | Silver Nuggets, Quartz Crystals | Iron / Steel Sword + Leather Armor |
| Floors 11 to 14 | Blood Mages, Shadow Wraiths | Gold Nuggets, Sulfur, Diamond Chunks | Steel / Damascus Sword + Iron Cuirass |
| Floor 15 (Sanctum) | Ancient Gate Sentinel Boss | Ancient Core, Dark Relics | Damascus Sword + Steel Plate Armor |
Floors 6-10 are the prime farming zone for Silver Nuggets, while Floors 11-14 provide the only renewable underground source of pure Gold Nuggets in the valley.
Every 5th floor features a heavy wooden gate operated by a wall lever. Pull the lever to unlock a direct stairwell shortcut back to the church basement.
Dungeon Chests, Ancient Relics & Boss Rewards
Securing the rare artifacts that conclude main character questlines and portal repairs.
Unlike surface resource nodes that respawn over days, Catacomb breakables and treasure chests reset on a cyclical dungeon cooldown. Barrels and sarcophagi frequently contain rare alchemical powders, silver coins, and preserved jewelry.
The deepest chamber on Floor 15 houses the Ancient Gate Sentinel. Defeating this mechanical colossus rewards the Ancient Core, the critical relic required by both the Astrologer and Snake to align the Valley Portal for the game's finale.
| Treasure Type | Location / Floor | Contained Artifacts | Questline Impact |
|---|---|---|---|
| Sarcophagus Cache | Floors 3, 7, 12 | Polished Gems, Silver Coins | Finances high-tier trade permits |
| Mage Altar Chest | Floor 9 Secret Room | Dark Organs, Blood Flasks | Supplies Snake's Act II dark rituals |
| Alchemist Laboratory | Floor 13 Alchemy Nook | Elixir of Gold, Toxic Extracts | Saves high-level potion crafting time |
| Floor 15 Boss Chest | Guardian Sanctum | Ancient Core, Royal Seal | Mandatory item for Main Story Portal Ending |
Clearing the full dungeon once awards over 15 Silver Coins in direct chest gold, plus enough rare minerals to forge a full Damascus weapon set.
The Catacombs drop over 20 distinct item types (ores, jellies, wings, bones, gems). Expand your inventory or empty your pockets before descending past Floor 5.
The Essential Dungeon Exploration Loadout
Assembling the ideal inventory loadout for extended 5-floor catacomb expeditions.
Descending beyond Floor 5 without adequate preparation is a recipe for sudden death. Inventory space is at a premium, meaning you cannot afford to carry redundant equipment. The ideal dungeoneer loadout reserves half of your inventory slots for harvested monster loot, ores, and treasure chest finds.
Always carry 10 Sauerkraut for continuous stamina regeneration, 5 Healing Draughts hotkeyed for emergencies, a Whetstone to maintain blade sharpness, and 20 Coal for emergency torch crafting. With this loadout, you can sweep from Floor 6 through 10 in a single uninterrupted descent.
Step-by-Step Strategic Walkthrough

- Acquire the Ancient Key from the Astrologer and decipher the Gate Activation Sequence at your Study Table.
- Descend through Floors 1-5 armed with an Iron Sword to harvest Bat Wings, Jelly, and early iron ore.
- Unlock iron shortcut gates on Floors 5 and 10 to bypass cleared upper levels on subsequent runs.
- Equip Steel Armor and a Damascus Sword to conquer Floors 11-15, mining Gold Nuggets and defeating the Floor 15 Guardian.
