Resource Management and Materials
Materials serve as the primary resource type in Horripilant. You use them to upgrade your equipment and build vital constructions within the dungeon. Gathering these resources effectively is the key to your long term survival and progression.
Collecting Materials
You gather materials simply by clicking on them. As you play, keep a sharp eye out for sparkles . Sparkles rewards you with a massive bonus, instantly granting you 500 times your current material click value.
Material Progression
You will encounter three core materials as you progress through the game:
- Wood: Your very first introductory material. You use wood for early equipment upgrades and initial dungeon constructions.
- Rock: The second tier of building resources. You need rock to push your equipment upgrades further.
- Iron: The third tier material required for advanced upgrades and high level constructions.
Upgrading Your Economy
To thrive in the dungeon, you must invest your resources back into your economy. You have four main upgrade paths to enhance your material generation:
- Upgrade Click: This enhancement increases the base amount of materials the game gives you every single time you click your mouse.
- Material Level: This acts as a powerful mathematical multiplier. It multiplies all material gain for that specific resource by its current level. For example, a base gain of 100 per second becomes 200 per second at level 2, and 300 per second at level 3.
- Upgrade Storage: This essential upgrade dictates the total amount of material that is able to be stored. Upgrading it increases your maximum holding capacity for a specific material by an order of 10.
- Hire: This provides you with passive, automatic material generation so you can earn resources while focusing on combat and exploration.


Mastering the Combat System
Combat in Horripilant handles itself automatically based on the equipment you wear. Your core loadout consists of a Sword, Helmet, Chestplate, Leggings, Boots, and a Familiar.
Active Combat Mechanics
While your character fights automatically, you can drastically increase your damage output by interacting directly with the enemy. Enemies display visual weak points during encounters. You can click these weak points to trigger extra attack attempts and gain an immediate advantage over your foe.
Familiars
A familiar is a friendly creature that fights alongside you. Beyond adding offensive power, familiars provide massive defensive utility. Whenever an enemy strikes you, your familiar absorbs half the impact, splitting the incoming damage evenly between the two of you. You create familiars using Meat gathered from fallen enemies.
Bosses and Boons
Every floor concludes with a challenging boss fight. Defeating a boss grants you a Boon. Boons provide a temporary stat boost or effect that only lasts for your current run. These effects completely reset the moment you leave combat. You can view your active boosts in the Current Boons Effects panel. If you see a boon label written in orange text, that specific stat is capped and you cannot increase it any further.
Navigating the Combat Interface
The combat screen features several critical tools to help you manage your dungeon crawl:
- Action Log: Tracks your recent combat actions, enemy spawns, defeated foes, experience points, meat gained, and selected boons.
- Depth Display: Shows exactly how deep you currently are within the current floor.
- Enemy Info: Reveals the enemy level, name, health bar, damage, defense, and evasion. Pay close attention to the white bar located beneath the enemy health bar. This tracks their attack speed, and the enemy attacks you once the bar fills completely.
- Floor Looping: Toggle this button to continuously loop floors.
- Exit At: Select a specific floor and click the door button on the left to automatically leave combat upon reaching that destination.
- Leave After Current Fight: Available exclusively on floor 1, this toggle allows you to safely exit combat the moment you defeat your current opponent.
- Select Boon Automatically: This toggle automatically picks a boon for you after a boss fight, making it highly useful for long idle dungeon crawls.
- Give Up: This button allows you to instantly flee combat. However, the game essentially treats this action as a death, and you will lose a portion of your collected Meat.


Essential Stats and Terminology
Understanding the underlying numbers and vocabulary will help you optimize your character for deeper and much more successful runs.
Offensive and Defensive Stats
- Damage: The raw numerical pain you inflict upon your enemies in combat.
- Critical Hit: A specialized strike that deals significantly increased damage to a target.
- Opportunity Attack: A retaliatory strike you perform immediately after an enemy attacks you.
- Vampire Hit: A specialized attack that transfers a portion of the damage dealt directly into healing for your character.
- Reflection: A defensive damage mechanic. If an enemy strikes you and reflection triggers, you bounce a portion of that damage back at the attacker.
- Defense: The total percentage of incoming damage your armor absorbs. For instance, a 75% defense stat means you only receive 25% of the actual incoming damage.
- Evasion: The percentage chance of you or the enemy missing an attack entirely.
- Click Power: The exact amount of materials you gain per single click.
Health and Progression Metrics
- Exp: Player experience points gained from combat. Leveling up your character increases your player maximum health capacity.
- Meat: The primary currency dropped by slain enemies. You use Meat to create familiars, increase your material storage limits, and purchase consumables.
- Regen: Your player health regeneration rate. Outside of combat, you regenerate at a minimum of 0.3% of your current maximum health every second. This means you will reach full health in roughly 30 seconds. If your character boasts a regen stat higher than that percentage, the game uses your higher regen value instead.
- Item Slot: A dedicated inventory space which contains a consumable item like a Healing Potion or a Spiky Bone.


The Rebirth Mechanic
Rebirth serves as the core prestige process of this game. It allows you to reset your progress in exchange for powerful, permanent upgrades that make your subsequent runs significantly easier.
The Prestige Process
When you choose to undergo Rebirth, the game resets all of your stats and basic progression. However, you retain all skills bought within the rebirth skill tree, the effects of those skills, and any items or progression related to your exploration.
Gathering Hemalith
Rebirth requires Hemalith, the specialized currency of the prestige system. You earn Hemalith by going deeper into the dungeon. The game calculates your Hemalith gain based strictly on your maximum depth, providing a base value of 1 Hemalith for every newly cleared deeper floor. Various stat boosts and Rebirth Skills can multiply this base number to accelerate your currency gain.


Solving the Dungeon Riddles
The dungeon holds many secrets, puzzles, and locked doors. To conquer the final challenges, you must clear from floor 1 to floor 1000 consecutively to open the final door. Along the way, you will earn unique items required for solving environmental riddles.
Riddle Solutions
Here are the exact solutions to the major riddles blocking your path:
- The Ghost: You must kill the ghost using the instakill medallion. You can purchase this medallion in the equipment shop. Before using it, you must sacrifice a pet on the spike and activate the water using the lever. Once you successfully take out the ghost, the game automatically writes the required code directly into your book.
- The Spider: In the room filled with webs, you need to draw the spider closer to you. Shake the webs using your cursor to clear them. If you open your map and leave it open for a while, the spider will begin to move away.
- The Mushroom: Locate the Mushroom and insert your collected medallions into his eyes. He keeps a copy of the map on his desk. Open your own map and click it in the exact same pattern shown on the Mushroom’s desk.
- The Well: You need both the coin and the handle for the well. Make sure you click the handle to operate it, and carefully observe what happens within the green world.
- The Angels: The angels will ultimately reveal the code to you, but the code actually displays on the main menu. Navigate to your settings and exit to the main menu through there. Do not close out of the game entirely, or you will get the incorrect code.


Creating Custom Portraits
If you own the Supporter Pack DLC, you can completely personalize your character by importing custom portrait artwork into the game.
Setting Up Your Files
To begin, navigate to the supporter folder located inside your game installation directory. You can find this by right clicking the game in your library, selecting Proprieties, navigating to Installed Files, and clicking Browse.
Once inside the directory, open the /portraits/ folder and create a brand new folder with a unique name. Inside this new folder, you must place your desired images using specific file names:
- normal.png: Your normal character portrait for when you are healthy.
- scared.png: Your scared character portrait for when you are low on health under 10%.
- bg.png: An optional file if you want a custom background behind your character.
- thumb.png: The small thumbnail image shown in the settings menu. The recommended size is 128×128 pixels.
Best Practices for Portrait Artwork
For the absolute best visual results, format your images as perfect squares with a 1:1 ratio. The biggest size the game displays the image at is 300×300 pixels, so aim for this exact resolution. The engine will scale your image up and down regardless of the starting resolution.
The game applies a dithering filter that posterizes and crunches down the pixels of your image to match the gritty aesthetic of the dungeon. Because of this, I highly recommend using images with strong contrasting colors to keep your character as legible as possible.


Conclusion
Surviving the grim world of Horripilant demands a sharp mind for puzzle solving and a strategic approach to resource optimization. By applying the tactics outlined in this guide, you will easily solve the trickiest environmental riddles and maximize your Hemalith gain for incredibly powerful prestige resets. You now possess the ultimate knowledge to automate a massive material economy and dominate the deepest floors of the dungeon.
