What Is Demonology?
Demonology is a co-op horror investigation game on Roblox where teams of up to 6 players enter haunted locations to hunt ghosts. Your job is straightforward but terrifying: find the ghost, gather evidence with specialized equipment, figure out which of the 16 ghost types you are dealing with, and get out alive. Think Phasmophobia meets Roblox, but with its own unique twists and ghost behaviors that keep veteran players guessing.
The game currently sits at around 10,000 concurrent players on any given day, with an all-time peak of 14,322 CCU. Each server holds up to 30 players in the lobby, but missions are capped at 6-person teams. The average play session runs about 8.52 minutes per round, which makes it perfect for quick sessions or extended ghost hunting marathons. Developer Blaqk Magic Blue keeps the game updated regularly, with the last update dropping just 2 days ago.

How to Hunt Ghosts Step by Step
Whether you are a fresh hire or a seasoned investigator, following a solid process makes ghost identification faster and safer. Here is the workflow that experienced Demonology players swear by.
- Form your team. Gather up to 6 investigators in the lobby. Communication is everything in this game, so play with friends or find a group on Discord if you can.
- Grab your equipment from the truck. Load up with the essentials: thermometer, EMF reader, and video camera. These three tools cover the widest range of evidence types.
- Find the ghost room. Spread out and use the thermometer to scan every room. A significant temperature drop signals ghost presence. The ghost room is your base of operations for the rest of the investigation.
- Deploy equipment and collect evidence. Set up the video camera in the ghost room, sweep with the EMF reader, and use additional tools like the spirit box and UV light to gather secondary evidence.
- Cross-reference evidence in your journal. Open your journal and match the evidence you have collected against the 16 ghost types. Each ghost has a unique three-evidence combination.
- Submit your answer and escape. Once you are confident in your identification, log it in the journal and head for the exit before the ghost catches you.
All 16 Ghost Types & Evidence
Demonology features 16 distinct ghost types, each with unique behaviors and evidence signatures. Learning what each ghost does during a hunt and what evidence it leaves behind is the single most important skill in the game. Here is the full roster.
Spirit — The most common ghost type. Spirits have no real strengths but can be aggressive when provoked. They are often the default guess for newer players, but do not get complacent. A Spirit during a hunt is still dangerous. Evidence typically includes EMF Level 5, spirit box response, and ghost writing.
Wraith — Wraiths are nasty because they can teleport to players without warning. They do not leave footprints in salt, which is a key identifier if you notice other evidence but no UV traces near salt piles. Look for EMF Level 5, spirit box, and freezing temperatures.
Phantom — Phantoms drain your sanity faster than most ghosts just by looking at them. If you notice your sanity dropping unusually fast during sightings, you might be dealing with a Phantom. They disappear when photographed, which is both a clue and a survival tactic.
Poltergeist — If objects are flying across the room constantly, it is probably a Poltergeist. They interact with physical objects more than any other ghost type and can throw multiple items simultaneously. Great for evidence gathering since the activity is obvious.
Banshee — Banshees target one specific player and will ignore everyone else during a hunt. If you notice the ghost consistently going after the same teammate, call out a Banshee. The targeted player should stay outside while others investigate.
Jinn — Jinns are territorial and move extremely fast when hunting if the power is on. Turning off the breaker actually slows them down, making power management a strategic decision against this ghost type.
Mare — Mares thrive in darkness. They are more likely to initiate hunts when the lights are off and less aggressive in lit areas. Keep the lights on in the ghost room when you suspect a Mare.
Revenant — One of the most feared ghost types. Revenants move slowly when they have not spotted a player, but become incredibly fast once they lock onto someone. Hiding is your best bet because you cannot outrun a Revenant that has seen you.
Shade — Shades are shy and rarely show activity when multiple players are in the same room. If the ghost seems inactive when the whole team is nearby but goes wild when someone is alone, it is likely a Shade. Sending a solo investigator in can provoke it into giving evidence.
Demon — The most aggressive ghost type in the game. Demons attack more frequently, have shorter cooldowns between hunts, and are generally hostile. They can hunt at higher sanity thresholds than other ghosts, so be ready to run at any time.
Yurei — Yurei are powerful sanity drainers. They drain sanity aggressively when near players and tend to stay close to their ghost room. Smudge sticks are especially effective against Yurei, trapping them in their room for an extended period.
Oni — Oni are very active and frequently visible. They throw objects with more force and are more active when players are grouped together, the opposite of a Shade. If the ghost keeps showing itself and throwing things around, consider an Oni.
Hantu — Hantu move faster in cold rooms and slower in warm ones. If the power is off and the location is freezing, a Hantu becomes a serious speed threat. Keep the power on and warm areas accessible when you suspect this ghost type.
Yokai — Yokai are attracted to and angered by player voices. Talking near a Yokai during a hunt is a death sentence because it can hear you from further away. Stay silent or use text chat if you think a Yokai is hunting.
Myling — Mylings are unusually quiet during hunts. You will hear their footsteps only when they are very close, which means less reaction time. Listen carefully and watch for the flashlight flicker that signals a nearby hunt.
Goryo — The Goryo is tricky because its ghost orbs can only be seen through a video camera and it rarely wanders far from its ghost room. Setting up a camera and watching the feed remotely is the best way to catch Goryo evidence.
Investigation Equipment Guide
Your equipment loadout determines how fast you can gather evidence and how likely you are to survive. Here is every tool available in Demonology and when to use each one.
Core Equipment (Bring Every Round)
Thermometer — Your primary ghost room finder. Walk through the location scanning each room. When the temperature drops significantly below the ambient temperature, or hits freezing, you have found your ghost. Freezing temperatures are also evidence for certain ghost types, so the thermometer pulls double duty.
EMF Reader — Detects electromagnetic activity on a scale of 1 to 5. EMF Level 5 is a ghost evidence type that narrows down your identification considerably. Sweep the ghost room and areas where the ghost interacts with objects. Spikes happen in real time, so keep the reader active and watch for peaks.
Video Camera — Set this up in the ghost room pointed at the most active area. Ghost orbs appear on the camera feed and are evidence for several ghost types. The video camera also catches Goryo activity that is invisible to the naked eye. Place it, then monitor from a safe distance.
Secondary Equipment
Spirit Box — Used to communicate with ghosts through radio frequency. Ask questions in proximity to the ghost and listen for responses. Some ghosts only respond to the spirit box when the player is alone, others when the group is nearby. A confirmed spirit box response is strong evidence for narrowing down ghost types.
UV Light — Reveals fingerprints and handprints on doors, light switches, and windows. Ghost fingerprints are evidence for specific ghost types. Scan every surface the ghost has interacted with. UV evidence is often overlooked by newer players but can be the piece that clinches your identification.
Smudge Sticks — Not evidence-gathering tools, but survival tools. Lighting a smudge stick near a hunting ghost stuns it temporarily, giving you time to escape. Against certain ghost types like Yurei, smudge sticks also prevent the ghost from leaving its room for a while.
Salt — Place salt near doorways and in the ghost room. When a ghost walks through salt, it leaves traces you can detect with UV light. Wraiths famously do not leave salt footprints, which is a key differentiator. Salt also slightly irritates ghosts, increasing activity.
Sanity Mechanics & Cursed Objects
Sanity is the invisible timer ticking down during every investigation. You start at 100% and it drops gradually while you are in dark areas, witnessing ghost events, or near active ghosts. Once your team's average sanity drops low enough, hunts become significantly more frequent and dangerous.
Staying in well-lit areas slows sanity drain. Turning on lights in rooms you pass through is not just for visibility, it is a sanity preservation strategy. Some players rush through investigations specifically to submit their answer before sanity gets critically low.
Cursed Objects: Do Not Touch
Scattered throughout locations, you will find cursed objects like Ouija boards, voodoo dolls, summoning circles, and haunted mirrors. These items are traps. Interacting with them causes massive sanity drops, often 20-40% in a single use. They can also trigger immediate ghost hunts regardless of your current sanity level. The risk almost never outweighs the reward.
Experienced players treat cursed objects as environmental hazards. Call them out to your team so nobody accidentally interacts with one, and give them a wide berth. The only scenario where touching a cursed object makes any sense is if you have already identified the ghost and want to trigger a hunt on purpose for a challenge, which is a terrible idea for most players.
Team Strategies for Faster Investigations
Demonology rewards coordination. A well-organized team of 4 can clear investigations twice as fast as a disorganized team of 6. Here are the strategies that top players use.
The Split Search
At the start of every investigation, split into pairs and cover different sections of the location. Each pair should have a thermometer. This cuts the ghost room discovery time in half or better. Once someone finds the ghost room, call it out and regroup.
Equipment Rotation
Not everyone needs to carry the same tools. Assign roles: one player handles EMF and thermometer, another takes the video camera and spirit box, a third covers UV light and salt. This way you can gather all evidence types simultaneously once you have found the ghost room.
The Bait and Watch Strategy
If you suspect a Shade (inactive with groups), send one player into the ghost room alone while others monitor from a safe distance. For a Banshee, identify the target player early and have them stay outside while the rest investigate safely. Adapting your strategy to the suspected ghost type dramatically improves survival rates.
Communication Discipline
Call out evidence the moment you find it. "EMF 5 confirmed" or "Freezing temps in the bedroom" gives your team immediate information to start narrowing down ghost types. If you suspect a Yokai, switch to text communication during hunts since voice attracts them.
Game Passes & Badge System
Demonology offers three game passes that enhance your experience without being pay-to-win. Here is what each one does and whether it is worth picking up.
2x Money
Doubles the cash you earn from every completed investigation. If you play Demonology more than a few times a week, this pass pays for itself quickly. Money lets you buy better equipment loadouts and cosmetics, so doubling your income is a solid quality-of-life upgrade.
2x Experience
Doubles your XP gain, which means faster leveling and quicker access to higher-tier content. Useful if you are trying to catch up to friends who have been playing longer or want to unlock everything the game offers without grinding for weeks.
VIP
The VIP pass gives exclusive perks that enhance the overall experience. Exact benefits vary as the developer updates the game, but VIP typically includes cosmetic bonuses, priority features, and other quality-of-life improvements.
Badge System
Demonology has 14 badges that track your milestones and achievements. Three notable ones stand out. You're Hired is your first badge, earned by completing your first investigation. Corporate Approval comes from consistently successful identifications and shows you know your ghost types. Employee of the Month is the prestige badge that marks you as a top-tier investigator. Collecting all 14 badges gives you a real sense of progression and bragging rights in the community.

Advanced Tips & Tricks
These tips come from hundreds of hours of Demonology gameplay and the strategies that consistently lead to faster, safer investigations.
Thermometer first, always. Before pulling out any other equipment, sweep the entire location with a thermometer. Finding the ghost room in the first 60 seconds sets the pace for the whole investigation. Everything else builds on knowing where the ghost is.
The video camera + thermometer + EMF combo is king. These three tools cover the most common evidence types across all 16 ghost types. If you could only bring three items, bring these. They give you the widest coverage for narrowing down your identification.
Watch the clock on your sanity. Newer players tend to spend too long inside without checking sanity levels. After 3-4 minutes in a dark location, your sanity is likely below 50%. That is when hunts become frequent. Get in, gather evidence efficiently, and get out.
Use hiding spots proactively. Before you start investigating a room, identify the nearest hiding spot. Closets, lockers, and under beds all work. When a hunt starts, you have seconds to hide. Knowing where to go before you need to go there saves lives.
Lights are your friend. Turn on every light switch you walk past. It slows sanity drain, makes it easier to spot ghost interactions with objects, and limits the Mare's power. There is zero downside to lighting up a location unless you are deliberately trying to provoke a hunt.
Do not stack the ghost room. Having all 6 players crammed into the ghost room is a recipe for a team wipe. Keep 2-3 investigators inside gathering evidence and the rest monitoring from outside or watching camera feeds. This limits casualties during hunts.
Learn ghost behaviors, not just evidence. Evidence tells you what the ghost is. Behavior tells you what it is about to do. A ghost that stops throwing objects might be preparing to hunt. Sudden temperature drops in adjacent rooms could mean the ghost is roaming. Read the signs.

Frequently Asked Questions
Demonology currently features 16 different ghost types, each with unique behaviors, evidence combinations, and hunting patterns. From common Spirits to terrifying Revenants, every ghost requires a different approach to identify and survive.
The video camera, thermometer, and EMF reader combo is the fastest way to detect and identify ghosts. Start with the thermometer to locate the ghost room, deploy the video camera for ghost orbs, and sweep with the EMF reader for electromagnetic evidence. This covers the most evidence types across all 16 ghosts.
As of April 2026, there are no active codes for Demonology. Developer Blaqk Magic Blue typically releases codes during major updates and milestones. We update this page as soon as new codes are confirmed, so check back after the next game update.
Each Demonology server supports up to 30 players in the lobby, but investigation teams are capped at 6 investigators per mission. This keeps investigations balanced and prevents ghost hunts from becoming too easy with large groups.
Cursed objects like Ouija boards, voodoo dolls, and haunted mirrors cause massive sanity drops of 20-40% per interaction. They can also trigger immediate ghost hunts regardless of your current sanity level. The general rule is to avoid them entirely unless you have a very specific reason to use one and a clear escape plan.
Sanity starts at 100% and decreases while you are in dark areas, witnessing ghost events, or near active paranormal activity. Lower sanity increases ghost aggression and hunt frequency. Keep lights on, investigate efficiently, and avoid cursed objects to preserve your sanity as long as possible.
If you play Demonology regularly, the 2x Money pass is a strong investment. It doubles your cash rewards from every investigation, letting you unlock equipment and cosmetics much faster. For casual players who hop in a few times a month, it is less essential but still nice to have.
Demonology averages around 10,000 concurrent players with over 359.2 million total visits. The all-time peak concurrent user count hit 14,322. With a 95.1% approval rating and active development from Blaqk Magic Blue, the player base remains strong and engaged.
