Snake Weekly Visiting Schedule and Dungeon Gates
Locating Snake beneath your church and opening the gateway to the 15-floor catacombs.
Snake lurks in the deepest shadows of the Church Cellar, appearing exclusively on Envy Day (marked by the green/silver flask symbol on the celestial wheel). He stands before the ominous subterranean gate, brooding over ancient rituals and dark summoning circles.
Interacting with Snake is non-negotiable for players seeking to descend into the Catacombs. He holds the ritual blueprints necessary to craft the Active Key, which unseals the stone entrance leading down into the subterranean monster depths.
| Quest Phase | Snake's Demand | Fulfillment Method | Unlock Granted |
|---|---|---|---|
| Initiation | 5 Faith points | Deliver Sunday church sermon | +10 Friendship, unlocks dialogue |
| Dungeon Key | Ancient Key Activation | Acid Flask + Key at Study Table | Opens Catacomb Floor 1 entrance |
| Blood Offering | 5 Bloody Nails & 1 Blood Pail | Defeat dungeon ghouls & morgue blood | +20 Friendship, unlocks Dark Organs |
| The Necronomicon | Deliver Occult Grimoire | Trade with Astrologer at Lighthouse | +30 Friendship, unseals Floor 10 gate |
| Dark Altar | Assemble Cellar Altar | 10 Stone, 5 Dark Hearts, 2 Skull Relics | Enables high-tier necromantic crafting |
Partnering with Snake provides the sole path to unlocking Dark Organs, which are mandatory for crafting 16-White Skull corpses and late-game alchemical weapons.
Bloody Nails can either be looted directly from armored ghouls on Catacomb Floors 1 through 4 or crafted by dipping regular Iron Nails into a bowl of morgue blood at Cooking Table II.
Dark Hearts, Occult Rituals, and Climax Confrontation
Harvesting cursed organs and navigating Snake's conflicting relationship with the Grand Inquisitor.
In Act II, Snake tasks you with harvesting Dark Hearts from incoming corpses. Doing so requires unlocking the 'Dark Tech' anatomy perk from the church Study Table. Purifying these cursed organs on your embalming table transforms their chaotic energy into massive white skull multipliers.
The climax of Snake's questline involves a tense subterranean confrontation where his dark summoning ritual threatens to awaken the Abyssal shade. Choosing whether to assist Snake or alert the Inquisitor branches into narrative endings B and C.
| Dark Component | Source Depth | Raw Skull Modifier | Purified Utility |
|---|---|---|---|
| Dark Heart | Catacomb Floors 5 - 10 | +2 Red Skulls (Cursed) | +3 White Skulls (Alchemical cleanse) |
| Dark Brain | Catacomb Floors 8 - 12 | +2 Red Skulls (Cursed) | +3 White Skulls (Cryo-embalming) |
| Dark Intestine | Catacomb Floors 10 - 15 | +2 Red Skulls (Cursed) | +3 White Skulls (Glue solution base) |
Integrating purified Dark Organs elevates your zombie automation efficiency to 60%, doubling their industrial production speeds.
Do not mention Snake's dark altar to the Grand Inquisitor until you have unlocked all 15 Catacomb floors, as doing so prematurely triggers a witch hunt lock on church cellar passages.
Subterranean Rituals & Dark Organ Processing
Unlocking the dark basement altar to channel occult blessings and avoid Inquisitorial suspicion.
Snake's operations in the church basement cellar run parallel to the Bishop's Sunday sermons. While the Bishop demands purity and white skull consecration, Snake thrives on the forbidden: Blood, Dark Hearts, and unholy pacts. Maintaining balance between these two diametrically opposed factions is essential to completing the main storyline.
Progressing Snake's cultic rituals to 80 friendship unlocks the Dark Altar upgrade in the basement crypt. Placing 5 Blood vials and 1 Dark Heart onto this altar grants the Necromancer's Eye perk, allowing you to instantly identify the exact internal organ skull counts of incoming corpses before lifting a scalpel.
Step-by-Step Strategic Walkthrough
- Clear the basement rubble in your Church Cellar to reach the heavy barred iron gate.
- Visit the ritual trapdoor on Envy Day during the evening or night to encounter Snake.
- Deliver 5 Faith points earned from your church sermon to prove your spiritual dedication.
- Obtain the Active Key from the Astrologer using Acid and Ancient Notes to unlock Dungeon Floor 1.
- Construct the Dark Altar in the cellar using 10 Stone, 5 Polished Wood, and 2 Dark Hearts.
Frequently Asked Questions

What are Dark Hearts used for in Graveyard Keeper 2?

How do you complete Snake's request to 'demonstrate you are worth talking to'?
