- Level Caps: Upgrades are divided into 7 distinct levels, each requiring previous tiers to be unlocked.

- Endgame Goal: Reaching Level 7 for the Charm Power upgrade, which allows equipping a second Charm.
Understanding the Abyssus Soul Wheel System
The Abyssus Soul Wheel serves as the backbone of your long-term progression. Unlike temporary buffs found during a single run, the upgrades purchased here are permanent, providing a significant advantage as you delve deeper into the abyss. By spending Soul Fragments (SF) earned during your expeditions, you can customize your playstyle, ranging from raw offensive power to utility-based survival.
The wheel is structured into tiers. To access higher-level upgrades, you must invest a specific amount of SF into the current level. This ensures a balanced growth curve where players must master early-game challenges before gaining access to game-breaking late-game abilities.
Offensive Growth
- Weapon Damage: Flat percentage increases.
- Ability Charges: Use skills more frequently.
- Execution: Instant kills on low-health foes.
Survival & Utility
- Max Health: Essential for high-difficulty runs.
- Syringe Charges: More healing opportunities.
- Revive Mechanics: A second chance at Level 5.
Economy & RNG
- Merchant Rerolls: Better control over gear.
- Starting Funds: Begin runs with Gold and Keys.
- Altar Spawns: Higher chance for rare buffs.
Soul Fragments are retained even if you fail a run. If you find yourself struggling with a specific boss, spend a few runs "farming" SF in earlier areas to bolster your stats through the Soul Wheel before attempting the challenge again.
Early Game Upgrades: Levels 1 to 3
In the early stages of your journey, your primary goal is consistency. The first three levels of the Abyssus Soul Wheel focus on stabilizing your damage output and providing basic quality-of-life improvements. At Level 1, every upgrade costs only 1 SF, making it easy to fill out the board quickly.
| Upgrade Level | Title | Effect | Limit | Cost (SF) |
|---|---|---|---|---|
| Level 1 | Enhanced Weapons | Increases Weapon damage by 3% | 5 | 1 |
| Level 1 | Upgraded Inventions | Increases ability damage by 4% | 5 | 1 |
| Level 1 | Bountiful Bottles | Increases Syringe charges by 1 | 1 | 1 |
| Level 1 | Picky Worship | Reroll Blessing Altar categories | 3 | 1 |
| Level 1 | Bartering | Reroll Merchant options for Gold | 1 | 1 |
As you progress to Level 2 and 3, the costs increase to 2 and 3 SF respectively. These levels introduce "World Modifiers," such as adding Healing Shrines to specific biomes like the Abandoned Temple or the Gardens.
| Upgrade Level | Title | Effect | Limit | Cost (SF) |
|---|---|---|---|---|
| Level 2 | Abyssal Stamina | Increases max Health by 40 | 5 | 2 |
| Level 2 | Ability Abundance | Increases ability charges by 1 | 1 | 2 |
| Level 2 | Temple's Rest | Healing Shrine in Abandoned Temple | 1 | 2 |
| Level 3 | Keen Vision | Increases Weakspot damage by 2% | 5 | 3 |
| Level 3 | Magazine Madness | Increases reload speed by 3% | 5 | 3 |
| Level 3 | Garden's Rest | Healing Shrine in the Gardens | 1 | 3 |
Do not ignore Bountiful Bottles at Level 1. Having that extra Syringe charge is often the difference between finishing a floor and losing all your progress. It is the highest-value 1-SF investment in the game.
Mid-Game Scaling: Levels 4 to 6
Once you reach the middle tiers of the Abyssus Soul Wheel, the focus shifts from basic survival to specialized power. Level 4 and 5 introduce some of the most impactful mechanics in the game, including the "Second Wind" ability, which provides a safety net for difficult boss encounters.
| Upgrade Level | Title | Effect | Limit | Cost (SF) |
|---|---|---|---|---|
| Level 4 | Ability Abundance II | Further increases ability charges | 1 | 5 |
| Level 4 | Bountiful Bottles II | Further increases Syringe charges | 1 | 5 |
| Level 4 | Abundance | More options available at Merchant | 3 | 5 |
| Level 5 | Second Wind | Revive with 20% Health (1/run) | 5 | 8 |
| Level 5 | Rapid Fire | Increases weapon fire rate by 3% | 5 | 8 |
| Level 5 | Beginner's Charm | Random Charm in the first room | 1 | 8 |
Level 6 is where the "Expert" tier begins. These upgrades are expensive (10 SF each) but offer unique mechanics like Execution, which allows melee players to instantly kill enemies below a certain health threshold. This is particularly effective against tanky elite mobs that appear in the later biomes.
| Upgrade Level | Title | Effect | Limit | Cost (SF) |
|---|---|---|---|---|
| Level 6 | Execution | Melee hits execute below 20% HP | 1 | 10 |
| Level 6 | Finer Charms | Increased chance for high rarity Charms | 1 | 10 |
| Level 6 | Picky Worship II | Spend SF to reroll categories | 1 | 10 |
Prioritize Second Wind as soon as you unlock Level 5. Even at its first rank, having a revive mechanic drastically changes how aggressively you can play against bosses. It allows you to learn attack patterns with much less risk.
The Ultimate Goal: Level 7 Charm Power
The pinnacle of the Abyssus Soul Wheel is Level 7. Currently, this level features a singular, game-changing upgrade: Charm Power. Charms in Abyssus provide powerful passive effects, but players are normally restricted to just one. Unlocking this node breaks that limit.
Upgrade Detail: Charm Power
- Effect: Allows equipping a second Charm simultaneously.
- Cost: 20 Soul Fragments.
- Limit: 1.
By equipping two Charms, you can create devastating synergies. For example, combining a Charm that increases fire damage with one that causes explosions on kill can turn a standard weapon into a room-clearing tool. Reaching this level requires a significant time investment, but it is necessary for tackling the highest difficulty "Surge Fissures."
SF Accumulation
Focus on "Speed Runs" through the first two biomes. These provide a high SF-per-minute ratio compared to struggling through the final areas.
Unlock Level 6 Nodes
You must purchase at least one upgrade from Level 6 to make Level 7 visible and purchasable.
Purchase Charm Power
Save 20 SF. Avoid spending on minor rerolls or lower-tier stat boosts until this is secured.
As the game evolves through its beta and official launch phases, Level 7 is expected to expand with more "Mastery" nodes. Keep your SF reserves ready for future additions to the Soul Wheel.
Progression Checklist & Priority
To maximize your efficiency, follow this recommended path through the wheel. This list prioritizes raw stats and survival over RNG-based merchant rerolls.
Essential Upgrade Path:
- Max out Enhanced Weapons (Level 1) for base damage
- Unlock Bountiful Bottles (Level 1) for extra healing
- Invest 5 points into Abyssal Stamina (Level 2) for 200 extra HP
- Unlock Ancient Forge (Level 2) to enable mid-run upgrades
- Secure Second Wind (Level 5) for the revive mechanic
- Reach Level 7 and unlock Charm Power for dual-charm builds
If you prefer a "Mage" style playstyle, prioritize Upgraded Inventions and Ability Abundance over weapon damage. The Soul Wheel is flexible enough to support both archetypes effectively.
Frequently Asked Questions
Q: How do I earn Soul Fragments for the Abyssus Soul Wheel?
Soul Fragments are dropped by enemies, found in chests, and awarded for completing objectives during an expedition. You keep these fragments even if you die, allowing for permanent progression.
Q: Can I reset my points in the Soul Wheel?
Currently, there is no 'Respec' option. However, because you can eventually unlock every node on the wheel, your early choices simply determine the order of your power growth rather than locking you out of content.
Q: Does 'Second Wind' work more than once per run?
No, 'Second Wind' is limited to once per expedition. After it triggers and revives you with 20% health, the effect is consumed until you start a completely new run.
Q: What is the total cost to max out the Soul Wheel?
To fully max every node including all limits, you will need several hundred Soul Fragments. It is designed to be a long-term goal that spans dozens of hours of gameplay.
