"The Nightwatcher. The Priest. The Vermin Duke. Three who saw their lives drawn into the Mansus, and rose higher for it. The ethereal plane always shifts and changes, working to find new influences, new students. Now, like us, you are aware. Mortality is a shell you wish to cleanse. Open the book, and learn how."

So you're a heretic? Well, get ready for some magic and battle. Grab those influences, make some sacrifices, and ascend as an immortal Long.


You are a nasty little bookworm in search of truth and power, and you have arrived on a station ripe with opportunities. The ultimate goal of a heretic, aside from completing their standard traitor objectives, is to gain power points to unlock their abilities.

You can increase your power in two ways: harvesting magic energies from the eldritch influences around the station, or by sacrificing any crew members to feed your research. To aid this task, you start with two items and a spell:

  • Heretic forbidden book.png The Codex Cicatrix, used to draw runes and research.
  • Heart.png The Living Heart, used to transmute and find your targets.
  • Mansus grasp.gif Mansus Grasp, a modular spell that, without upgrades, lets you touch a target to cause knockdown and light burn damage on a 15 second cooldown. As you grow in power, your grasp will gain additional effects.

All of these are critical to your ascension, so don't lose them, and keep them hidden from security! Should you lose these occult items, you can transmute new ones using your victims, and items around the station.

  • In order to transmute a new Codex Cicatrix, you'll need human flesh, a pair of eyes, a bible, and a pen.
  • Transmuting a new Living Heart requires a new heart, a splatter of blood, and a poppy flower.

Reality fracture.gif Influences are the easy way to gain power points. Whenever there are heretics aboard Space Station 13, influences will randomly spawn across the station after sometime into the shift. Initially, influences flicker with bursts of energy similar to electricity, have randomized names, and can only be seen by heretics. To harvest an influence, simply hit it with your codex and remain still for four seconds. After being harvested, the influence will lose it's electric-like bursts, gain a yellow glow with a rainbow border originating from the middle, change their name to pierced reality, and become visible to the entire crew. Influences can only be harvested once, so don't waste time trying to collect those that other heretics have already taken!

Reality fracture harvested.gif An already harvested influence. Notice the glow.

Once you have some power points, it's time to research! Simply use your codex in-hand to open the research menu and spend your points on abilities. The research menu forms a branching tree (see below), and your first selection will be to commit to a lore (also known as a path). Your lore determines what special abilities your Mansus grasp and Heretic blade may have. In addition, it ultimately decides the ascension you will be able to achieve. When you choose your path, you will immediately gain your associated Heretic blade. Otherwise, you are free to gain any research within the tiers; you need three of a tier before you're able to claim your lore-specific upgrade and unlock the next tier of research.

Eventually, you'll need to start using proper magics. By hitting any empty tile with your codex, you'll begin to draw a transmutation rune, which takes 8 seconds. These runes are green and take up a 3x3 area, and while they can go under other objects, it's best to keep them clear for transmutation purposes. You can remove runes by hitting them with your codex again, and freely use other heretics' runes. To transmute, simply click the rune with an empty hand while the appropriate object(s) are on top of it, making sure that nothing else is in the way. You can only have one transmutation rune active at once, so creating a new one will destroy the old one.

Heretic blade.png The Heretic Blade will be your first unlocked research. It can be created by transmuting a common knife with a secondary ingredient based on your path, and serves as a powerful melee weapon. As with the Mansus Grasp, your blade will be upgraded by your research over time. If you lose your blade, simply transmute a new one. A shank can be quickly crafted and used in all transmuting ingredients to make a new Heretic blade. While you do begin your path to ascension with one, it can help to make more, as shattering one can providing a quick escape to a random, safe part of the Z-level. It takes two seconds to break the blade, so make sure you have the time to do so!

In addition, the blade has the added benefit of shield-breaking and a ranged option. If your blade manages to strike a target who carries a shield, the shield will be destroyed. Furthermore, the blade can be used as a ranged hook on a 3-second cooldown. Hitting a target pulls them to you and immobilizes them for a very short duration: just enough to let you get a hit in. With good good, armor penetration, and wound chance, the blade is your bread-and-butter of dealing with unsavory individuals.

The most important use of your rune is sacrificing. To get a sacrifice target, drop your living heart onto a rune and transmute it with nothing else present, making sure your codex is in your inventory. You'll be given a target, and can then squeeze your living heart by using it in-hand to get a vague idea of where your target is as well as if there's anyone around them. Kill them, drag them back to a rune, and transmute their body along side your living heart to messily sacrifice them and earn a power point. They might show up later, but don't worry! They won't have any memory of your brutal murder, so you don't have to worry about them ratting on you to security.

Between influences and sacrifices, you'll eventually unlock more and more abilities; the last ability will be your ascension, which guarantees a greentext and gives you massively powerful benefits or transformations. Once you've ascended, all that's left is to unleash your fury upon the crew! Use all of your powers to slaughter everybody who dares stand up to you, or just bask in your dark glory.

Lore and Paths

There are different aspects of the arcane to which you can devote yourself. While all rituals and spells can be learned, your first and most important choice will decide how your weapon Heretic blade.png and grasp Mansus grasp.gif will evolve, and how your final ascension will transform you.

Path Name Description
Path of Ash Nightwatcher's Secret Ash is the principle of spirit and ambition, and the everlasting flame that burns bright with the kindling of life. You will become more resistant to heat and several of your abilities will involve fire. As your Mansus grasp gains the ability to fling, this path is best suited for direct combat. As setting individuals on fire is very powerful and this path is the most basic in how its abilities function, it's often recommended for beginners. Your ascension will make you indifferent to most environmental hazards, as well as granting you massive, fiery area-of-effects.
Path of Flesh Principle of Hunger Flesh is the principle of temptation and obedience, and the malformation of will. No doubt the most difficult path, your Mansus grasp and blade upgrades will focus on bleeding out targets. However, uniquely, your Mansus grasp will be able to revive dead bodies into ghouls that will serve you. While you aren't able to sustain many, they still serve as unique allies when you would otherwise only be able to wholly rely on yourself. Your ascension permits you to either metamorphosize as something greater, or summon something lesser, yet still grand to serve you.
Path of Rust Blacksmith's Tale Rust is the principle of that which makes and unmakes, and the slow decline of all things civilized. The most well-rounded path, your Mansus grasp will rust surfaces, or destroy rusted surfaces, granting you significant access. Its massive damage to non-organic matter also grants you a significant advantage over any silicons who might interfere with your research. Your blade can later work to destroy someone's equipment, or inject them with a reagent that will poison them. Your ascension spreads rust from your rite site, as well as granting you significantly more self-healing while you stand on rusted tiles.


Below is a table with all your abilities. Each Lore-specific upgrade will be available after gaining three research of the previous tier. This means you need three tier one abilities before you can claim your Grasp Mark, then three tier two abilities before you can claim your Blade Upgrade. As it follows, three tier three abilities are required before you unlock your Ascension Rite.

Note that while some tiered abilities are along their respective, flavored paths, they are NOT required for progression within your chosen lore. You could theoretically only acquire miscellaneous research and unlock each milestone through the progression, including your ascension rite.

You can NEVER gain the Lore, Path Grasp, Grasp Mark, Blade Upgrade, or Ascension Rite of a path different from the one you have chosen.

It burrows in the hearts of all living things. Eternal cycles of time yield nothing more from it. We know not what it is, and know better than to ask when it reveals itself. Forgotten to ages as the Priest's inspiration. They were decadent and deceiving, devouring the dead below the Glory, capturing them for themselves. We believe their autocannibalism will never abate. A conniving, contemptuous creature. He cackled and cried as the meteor began to take his wits into its own usage. We know not if he still lives, though his servants do.

The one who lived. She never recovered her eyes. It is less likely she will find justice. Yet she listens to us when we sing with pain and malice. There are some wrongs that can still be righted. Some entity that takes a variety of forms, though she prefers a feminine visage. She finds those who dare wander the Mansus without proper care, though she has been instructive to us in passing. A poor man who gave in to the whims of the Empress. He believed royal payments would cure the ails of his wife. We still offer thanks for the blades he gifted to us.

They were stoic and loyal, unlike their superior. Amgala could not have asked for better protectors or better scholars. But now they are gone. Still they wither in their graves, where we sometimes offer condolences. The Priest's loyal followers, bound to the Red Oath and enthralled with the Glorious Feast. Timeless cycles see their ranks replenished and drained with each coming Feast. We try to stray far. He has gone where others cannot go. Seen what others cannot see.

Terror of the night armsy.png
Transmute three corpses to ascend by metamorphisizing as a Thirstly Serpent, or ascend instead by summoning a Lavish Serpent, tripling your ghoul maximum, and becoming incredibly resilient to damage.
Transmute three corpses to ascend as a Sovereign of Decay. Your healing on rust tiles will be tripled, and you will become much more resilient to damage. In addition, rust will spread from your ritual site. A pact of demons and marauders from a world forgotten. Very few yet roam the planes. The secrets to their final defeat have been lost. We offer wardings to ensure they do not cross our path. One of the oldest and sanest Sworn. Ebis, like the Lover, we believe to be a being of the Mansus itself. They commonly offer generous aid, but only if we succeed in one of their puzzling challenges. We know it from the scribblings of those in the comet's wake. It is perhaps more a force than an individual. It is the star itself. And it hates all that built.


  • If your transmutations are failing, make sure your codex is on your person!
  • Many unlockable transmutations require body parts or whole corpses. You can get these from your victims, as well as by raiding the Morgue, or with the correct access, turning monkeys into catatonic humans.
  • Even if you never fight other heretics, you're inherently at odds with them. Each influence can only be harvested once, so the heretic that goes the fastest and grabs the most influences first has to do less killing and sacrificing to reach their ascensions.
  • As a heretic, access is more important than ever! The more areas you can easily access, the more influences you'll be able to snag. Getting all access can be a godsend, and knowing how to either hack or talk your way into other departments can help you beat other heretics to the free points.
  • Even after ascension, you aren't completely invincible. Don't get too hasty and end up eating a barrage of deadly lasers to the face.
  • As mentioned before, no matter which heretic blade you choose, each one will have an option to destroy it. Afterwards, it will teleport you to a random spot on the Z level. This provides a very good last ditch option for escaping the authorities. As it takes two uninterrupted seconds, make sure you're clear before you use it.
  • With rust, you can practically melt through walls. Use this to your advantage when you and other heretics end up in the Brig.
