Dotemu's Absolum was already one of the stronger indie roguelikes to come out of 2025, and the Threads of Fate update makes a convincing case that the post-launch roadmap is worth paying attention to. This first major update adds corrupted areas that shake up every run, a dedicated post-game mode called Mystic Ordeals, new Soul Tree content to spend your crystals on, fresh skins for every character, and a full Ritual system that forms the backbone of every build you'll ever put together. Here's everything you need to know.
What are corrupted areas and how do they work?
Corrupted areas are the most immediately noticeable change to standard runs in Threads of Fate. According to TheGamer's coverage of the update, corrupted areas appear randomly on the map, glowing blue to signal their presence. When you enter one, portals open and spawn powerful enemies from later sections of the game, which means you can run into late-game elites well before you'd normally face them.
This mechanic is a reworking of the portal system that existed in the base game after you defeated Sun King Azrah, but with one key difference: you can't turn them off. They're a permanent feature of every run now, which means you need a plan for them rather than just hoping they don't appear.
The risk-reward logic here is straightforward. Corrupted areas yield more crystals and better Rituals than standard encounters, according to the source. The elite enemies that come through the portals are reportedly even stronger than their base-game versions, so you're trading real danger for better loot. If you can route around them, that's a valid call. If your build is in good shape and you want the best Rituals available, pushing through a corrupted area is worth the gamble.
Elite enemies in corrupted areas appear to be stronger than their base-game counterparts, not just reskins. Don't walk in underprepared expecting a standard fight.
What are Mystic Ordeals and how do you unlock them?
Mystic Ordeals are the dedicated post-game mode added by Threads of Fate. To access them, you need to have completed the game's final true boss at least once, then speak to the hooded figure in the bottom right of the hub. That's your gateway to the Ordeal system.
Each Mystic Ordeal is a run built around set conditions, ranging from lifesteal modifiers to increased enemy counts to buffed attack types that demand you lean into a specific playstyle. They're challenging by design, and completing them with each character or without using certain tools like companions earns you medals on top of the standard rewards.
If the difficulty is a wall rather than a challenge, Assist Mode remains available during Ordeals. You can still reduce or increase your damage output, which keeps the content accessible without removing it entirely.
Completing a Mystic Ordeal unlocks more Ordeals in sequence. The first new character skin doesn't appear until you've cleared at least two of them, so push through that early gate as quickly as you can.
Completing Ordeals also expands the Soul Tree with new sections, which is where the long-term progression loop lives. You'll need to clear a significant number of Ordeals to see all the new content, but the payoff includes some genuinely useful unlocks.

What's new in the Soul Tree?
The Soul Tree additions are gated behind Ordeal completion. According to TheGamer, these new sections appear after you've beaten your first Ordeal run (which typically means clearing the final boss again as part of that Ordeal). From there, each additional Ordeal you clear opens up more of the tree.
The new unlocks include:
- Two skins per character, the first of which requires at least two Ordeal completions
- Character-themed emote sets
- Ordeal modifiers that let you adjust future runs
- Upgrades that buff Heathroot effectiveness or increase attack strength
- The ability to start a run with an Inspiration that would normally only drop from bosses
That last one is significant. Boss Inspirations are some of the strongest run-starters available, and being able to begin with one changes how you approach early routing.
Not every Soul Tree addition is locked behind Ordeals. Some unlocks tied to Heathroots and attack buffs are available earlier in the new tree sections.

How does the Ritual system work?
Rituals are the core build-crafting mechanic in Absolum, and understanding them is what separates runs that fall apart in the mid-game from runs that snowball into something unstoppable. According to the Absolum Wiki, Rituals are offered as choices at the end of non-boss, non-story locations, presenting 2 options by default (or 3 with a specific Vikhana upgrade). You pick one and it modifies your character for the rest of that run.
There are 8 Ritual families in total, each with its own elemental identity and mechanical keywords:
A single run will naturally offer up to 3 different families, but you can expand your pool by purchasing Rituals outside your current selection, according to the wiki.
What are the four Ritual types?
Every Ritual falls into one of four categories, and knowing which type you're picking matters for how your build develops:
- Core Rituals attach the family's main mechanic directly to your attacks (Lightning Strike, Blazing Dash, etc.)
- General Rituals give global upgrades that work regardless of loadout, while staying thematically tied to their family (Rupture, Tornado Jump)
- Enhancement Rituals upgrade a specific family mechanic and usually require you to already have a related Ritual before they appear
- Twin Rituals belong to two families simultaneously and require you to have Rituals from both families to unlock them
Twin Rituals are where some of the most powerful interactions live. Combinations like Spark Combustion (Fire + Thunder), Fiery Skeleton (Fire + Necromancy), and Cosmic Thunderstorm (Thunder + Chaos) represent the kind of cross-family synergy that can define a run.
How does Ritual leveling and stacking work?
Most Rituals can be picked up multiple times, increasing their Level up to a maximum of 3. The wiki documents the scaling clearly: Level 2 is roughly 50% stronger than the base value, and Level 3 is 100% stronger. Certain Soul Tree upgrades can make Level 2 and Level 3 versions appear immediately, skipping the upgrade process.
Stacking is a separate mechanic that kicks in when you hold multiple Rituals that enhance the same underlying mechanic. The wiki gives a concrete example: holding two Level 1 Rituals that trigger Tidal Waves (Wave Dash and Wave Landing) pushes Small Tidal Wave damage from 4 to 6 and increases pushback distance from 20% to 30%. The power increase from stacking is roughly equivalent to one full Level, though it varies between mechanics.
Ritual Power is a hidden stat that scales the damage and effects of a given family's mechanics. It's boosted exclusively through Trinkets, specifically Moxes and the Crown of Harmony. Crucially, Ritual Power increases are multiplicative: two copies of Fire Mox result in x1.21 Fire Ritual Power rather than a flat +20%.
Where do you find Rituals outside of standard rewards?
The main source is the end-of-scene reward, but the Absolum Wiki notes several alternative acquisition paths:
- Fallen Hunters can drop Rituals as a random event (sometimes at a cost in HP)
- Certain shops, including the one in Misty Grove, stock Rituals for purchase
- NPCs that appear during runs can offer Rituals as part of their interactions
This matters because buying a Ritual from a shop that isn't in your current run's family pool is how you manually add a fourth or fifth family to a single run, opening up Twin Ritual combinations that wouldn't otherwise be available.
