Core Progression and Boss Challenges
In the unforgiving depths of the Royal Abyss, abyssus challenges serve as the roadmap for your character's growth. The journey begins with basic survival and quickly escalates into high-stakes boss encounters. Completing these milestones is not just about prestige; it is the only way to earn Soul Fragments and unique character archetypes like the Diver or the Explorer.
For players just starting their expedition, focusing on the "First of Many" and "Big Game Hunter" challenges is essential. These introduce the core loop of failing, learning, and eventually overcoming Elite enemies. As you descend further, the bosses of the Abandoned Temple, Gardens, and Sanctuary will test your build's synergy and your mechanical skill.
Early Game Goals

| Challenge Name | Objective | Primary Reward |
|---|---|---|
| Big Game Hunter | Defeat your first Elite enemy | Soul Fragment(s) |
| Royalty | Defeat the Abandoned Temple boss | Soul Fragment(s) |
| Legend No More | Defeat the Gardens boss | Soul Fragment(s) |
| Twisted | Defeat the Sanctuary boss | Soul Fragment(s) |
| A Kingdom Toppled | Defeat the final boss of the Abyss | Soul Fragment(s) |
| First of Many | Fail an expedition for the first time | Revenant |
Boss challenges are best tackled with a balanced build. Prioritize Health blessings early on to ensure you can survive the "Royalty" encounter, as the Abandoned Temple boss features high-mobility attacks that can catch new players off guard.
Weapon Specialization and Mastery
The variety of weaponry available is the cornerstone of the game's combat system. To truly master the abyssus challenges, you must step outside your comfort zone and utilize every tool in your arsenal. Weapon-specific challenges often require you to change your playstyle, such as focusing on explosions with the Engine Rifle or managing Spark Orbs with the Tesla Gun.
Completion of these challenges unlocks "Mods," which are permanent upgrades that significantly alter how a weapon functions. For example, the "Frag Grenade Mastery" requires high-intensity usage but rewards you with mods that can turn a standard grenade into a room-clearing explosive.
| Weapon Type | Challenge Requirement | Reward / Unlock |
|---|---|---|
| Engine Rifle | Kill 30 enemies with explosions | Split Shot Mod |
| Tesla Gun | Hit 7 enemies simultaneously | Magnetic Storm Mod |
| Tesla Gun | Apply 100 DOT effects | Charge Beam Mod |
| Disc Thrower | Hit 5 enemies with one flame burst | Dynamo Mod |
| Seeker | Kill 4 enemies at the same time | Void Infusion Mod |
| Combat Bow | Complete an expedition | Pierce Mod |
Initial Weapon Selection
Choose a weapon you are comfortable with to clear the initial "Gun Meets Crown" or "Robin Hood" challenges.
Mod Accumulation
Focus on "Connoisseur" challenges by unlocking all primary and secondary mods for each weapon type.
Mastery Completion
Finish an expedition with every weapon in the game to earn the "Tall Neck" reward.
When attempting the "Drumfire" challenge for the Engine Rifle, look for blessings that increase explosion radius. This makes hitting the 30-kill requirement significantly easier in dense enemy clusters.
High-Skill Combat Milestones
Beyond simply killing bosses, the abyssus challenges include several high-skill tasks that require specific conditions or extreme damage outputs. "Exterminate" requires a single hit of 9,999 damage, while "Speedster" demands you finish an entire expedition in under 30 minutes. These challenges are designed to push the limits of your build-crafting.
One of the most difficult combat feats is "Unbeatable," which requires killing an Elite enemy using only melee attacks. This necessitates a build focused on damage reduction and melee speed, as Elites in the Royal Abyss are notoriously dangerous at close range.
| Skill Challenge | Requirement | Reward |
|---|---|---|
| Exterminate | Deal 9,999 damage in one hit | Overkill |
| Speedster | Finish expedition < 30 mins | Power From Pain |
| It's a Blast | 500,000 explosion damage total | Mr. Boom |
| Torment | 100,000 DOT damage total | Hex |
| Unbeatable | Melee kill on an Elite enemy | Slow Power |
| Squint | 30 kills beyond 40 meters | Hawkeye |
The "Agnostic" challenge requires you to complete an expedition without any blessings. This should only be attempted after you have fully upgraded your base stats and mastered enemy attack patterns, as you will lack the scaling power provided by Surge Fissures.
Survival and Utility Accomplishments
Not all abyssus challenges are offensive. Several key unlocks are tied to your ability to survive, manage resources, and interact with the environment. The "Meat Shield" challenge, for instance, rewards players who can sustain heavy damage, while "Locksmith" encourages thorough exploration of each floor to find and use keys.
Environmental interactions, such as lighting hidden braziers or using the Wishing Well, also provide unique rewards. The "Heads or Tails? Wrong." challenge is a test of patience, requiring you to fail at a Wishing Well three times in a single run—a frustrating but necessary step for completionists.
| Utility Challenge | Requirement | Reward |
|---|---|---|
| Meat Shield | Take 5,000 total damage | Bandage |
| Locksmith | Use 5 keys in one run | Skeleton Key |
| Wealthy | Carry 1,000 Gold at once | Gold Lure |
| Thick-Skinned | Reach 1,000 Maximum Health | Healthy Commitment |
| No Need | Complete run without Syringe | Hate Forged |
| Lightbringer | Light the hidden brazier | Ms. Boom |
Survival Mastery Checklist:
- Complete a run without using the healing Syringe
- Reach 1,000 Max Health in a single expedition
- Successfully navigate a run without any Blessings
- Find and light the hidden brazier in the Royal Abyss
To complete the "Wealthy" challenge, avoid spending Gold at mid-floor vendors. Instead, focus on "Fortune Blessings" that increase Gold drop rates from pots and enemies.
Endgame: Deep Water and Collection
The true endgame of abyssus challenges lies in the Deep Water levels and the total collection of all game assets. Deep Water Level 30 is currently the pinnacle of difficulty, representing a massive jump in enemy health and damage. Completing this level awards the "Military" skin, a mark of a true veteran.
Furthermore, the "Collector," "Scribe," and "Proficient" challenges require you to find every weapon, ability, skill, and logbook entry. This task involves significant RNG (Random Number Generation) and multiple runs to ensure every Blessing and Charm has been encountered and recorded.
| Endgame Goal | Requirement | Reward |
|---|---|---|
| Seasoned | Complete Deep Water Level 4 | Astronaut |
| Expert | Complete Deep Water Level 10 | Gas Mask |
| Master of the Abyss | Complete Deep Water Level 30 | Military |
| Collector | Unlock all weapons and abilities | Metal |
| Proficient | Unlock every skill in the tree | Pristine |
| The New Monarch | Complete ALL challenges | Admiral |
The "New Monarch" challenge is the ultimate goal for 2026. If you are struggling with the final weapon mods, focus on "Connoisseur" runs where you only pick up the specific weapon you need to master, ignoring other loot to maximize your focus.
