Cult of the Lamb has always been a game about balancing the adorable with the macabre, but with the Sins of the Flesh update, Massive Monster took the “macabre” to a whole new level. One of the most significant additions to the game is a new resource called Sin. Unlike Devotion, which represents the pure religious fervor of your followers, Sin represents their more carnal, indulgent, and darker impulses. If you want to access the endgame content, unlock the most powerful rituals, and customize your cult with more than just basic robes, learning how to unlock Sin in Cult of the Lamb is your first step toward true unholy power.
Setting the Stage for Iniquity
Before you can start harvesting the corruption of your followers, you must meet certain progression milestones. Sin is not available from the moment you start your first crusade in Anura or Darkwood. It is considered mid-to-late game content designed for players who have already established a solid foundation for their cult.
To trigger the Sin mechanics, you must first defeat at least three Bishops of the Old Faith. Whether you’ve cleared Leshy, Heket, and Kallamar, or any other combination, the game tracks your progress through the main story. Once the third Bishop has fallen, you must return to your base and perform a Sermon. After the Sermon concludes, a cutscene will trigger featuring a familiar yet slightly more chaotic visitor. This event introduces the concept of Sin and unlocks the initial building required to generate it.
Establishing the Temple of Indulgence
Once you have unlocked the Sin mechanic, your Crown will grant you access to several new structures in the Divine Inspiration tree. To start generating Sin, you need to provide your followers with outlets for their desires. The most basic and essential of these structures is the Drinkhouse.
The Drinkhouse allows you to use ingredients gathered during crusades—such as Grapes, Hops, and Berries—to craft alcoholic beverages. When your followers consume these drinks, they have a chance to generate Sin. However, be wary; followers who drink too much may become “Befuddled,” leading to fights or general chaos within the camp. This is the core loop of the Sin mechanic: trading stability and resources for a more volatile, powerful form of currency.
The Best Ways to Generate Sin Fast
Once you have the basics down, you will realize that you need a lot of Sin to unlock the highest tiers of the update’s content. Simply waiting for followers to have a beer isn’t enough. You need to be proactive in your corruption.
- The Drum Circle
The Drum Circle is a rhythm-based mini-game added specifically for Sin generation. By assigning a follower to the circle, you can participate in a musical sequence. The better you perform, the more Sin that follower generates. It is a reliable, active way to farm the resource without relying on passive consumption.
- The Mating Tent
Perhaps the most talked-about addition in the Sins of the Flesh update is the Mating Tent. When two followers with high compatibility enter the tent, they consume Sin to produce an egg. However, if you are looking to gain Sin rather than spend it, certain interactions and rituals surrounding the birth and the nature of the followers involved can result in a net gain of corruption.
- Rituals of Excess
The update introduced several new rituals specifically designed to spike your Sin levels. The Ritual of Lust, for example, forces your followers to cast off their inhibitions (and their clothes), generating a massive amount of Sin at once. There is also the Rite of Wrath, which encourages fighting among the ranks. While these rituals are effective, they often carry negative side effects, such as reduced faith or injured followers.
Managing the Consequences of Sin
Sin is a volatile resource. If a follower collects too much Sin (specifically, if they reach three bars of Sin in a single session), they will become “Damned.” A Damned follower will leave your cult entirely, vanishing into the lands of the Old Faith.
When a follower is Damned, you haven’t lost them forever, but you will have to work to get them back. During your subsequent crusades, you will encounter your Damned follower as a mini-boss. You must defeat them three times across your runs to “purify” them. Once defeated for the third time, they will return to your recruitment circle at the base, allowing you to re-indoctrinate them. This mechanic prevents players from simply spamming Sin generation on a single favorite follower without risk.
What to Spend Your Sin On
Unlocking Sin is only half the battle; knowing where to invest it is where the real strategy lies. Sin is used for more than just bragging rights.
- Tailoring and Outfits
The Tailor is a new building where you can spend Sin and Silk to craft unique outfits for your followers. These aren’t just cosmetic; many outfits provide specific buffs or change the behavior of the follower wearing them. From Maid outfits to Royal robes, the customization options are vast.
- Upgrading the Temple and Structures
High-level building upgrades now require Sin instead of just gold or wood. If you want the most efficient farms, the strongest refineries, or the most opulent decorations, you will need a steady supply of Sin.
- Purgatory and God Tears
In the endgame, Sin becomes a currency for interacting with the mysterious entity known as “The One Who Waits” (or his successors). You can use Sin to reset certain cooldowns or to influence the rewards you receive from Purgatory runs, which are essential for collecting God Tears.
Advanced Strategies for the Sinful Cult Leader
To truly master the Sins of the Flesh, you should aim for a “Sin Cycle.” This involves rotating your followers through the Drinkhouse and Drum Circle so that no single follower becomes Damned too quickly. By spreading the corruption across your entire flock, you can maintain a high income of Sin while keeping your best workers and warriors in the camp.
Another tip is to pay attention to follower traits. Some followers are “Alcoholics,” meaning they generate more Sin from the Drinkhouse but get sick more often. Others might be “Prudes,” making them harder to corrupt. Sorting your followers by their propensity for Sin will make your management much smoother.
Frequently Asked Questions
How many Bishops do I need to kill to unlock Sin?
You must defeat at least three Bishops of the Old Faith. After defeating the third one, return to your base and perform a Sermon to trigger the cutscene that introduces the Sin mechanics and the Sins of the Flesh content.
Why did my follower disappear after generating Sin?
Your follower has likely become “Damned.” This happens when a follower accumulates three points of Sin. They will leave your cult and appear as an enemy during your crusades. You must defeat them three times in the dungeons to bring them back to your cult.
What is the fastest way to get Sin without losing followers?
The Drum Circle is the safest and most consistent way to generate Sin. Since you control the mini-game, you can stop just before the follower reaches the “Damned” threshold. Combining this with moderate use of the Drinkhouse is the most efficient strategy.
Can I use Sin to resurrect followers?
While Sin itself isn’t the primary currency for resurrection (which still mostly relies on Bones and specific Rituals), some high-level interactions involving Sin allow you to manipulate the afterlife and the quality of followers you bring back to your flock.
Does Sin affect my cult’s Faith level?
Indirectly, yes. Many actions that generate Sin, like the Ritual of Lust or the Rite of Wrath, can cause a temporary dip in Faith or lead to negative status effects like “Befuddled.” You must balance your Sin generation with positive Reinforce Belief actions to keep your cult stable.
