ATLYSS Achievements Guide – 100% Unlock

Earning every trophy in this atlyss achievements guide is a rewarding journey that spans the entire game. While most milestones unlock naturally as you clear quests and explore the world, several missable and secret objectives demand deliberate exploration.

Full completion requires conquering difficult dungeons, reaching Level 10 to establish your base class, purchasing powerful subclasses, and acquiring cosmetic sets. You will also spend time studying Novice Skills and tracking down parkour secrets hidden in Sanctum and the Wall of the Stars.

Below, you will find a categorized breakdown of every achievement, complete with exact requirements and proven steps to unlock them efficiently.

ATLYSS Progression Achievements

A New Journey

This achievement unlocks upon completing your first introductory quest in the world of ATLYSS.

After finishing character creation, make your way straight to the central tower on the map. Speak with Angela to begin your orientation.

Accept and finish the starter quest A Warm Welcome (lv.1) to secure the A New Journey achievement right away.

Clearing Catacombs (1-6)

You need to successfully finish the introductory dungeon tier, Sanctum Catacombs (1-6).

Head into the Outer Sanctum zone to locate the entrance to this early dungeon instance.

Fight your way through to the final room and clear the instance to trigger the achievement.

Clearing Catacombs (6-12)

Complete the mid-tier catacombs instance, Sanctum Catacombs (6-12).

Like the first tier, you can access the Sanctum Catacombs (6-12) gate directly from the Outer Sanctum.

Simply reaching the final chamber will not suffice here. You must strike down the Lord Zuulneruda boss to register the clear and claim the trophy.

Becoming a Fighter

Advance any character into the martial-focused Fighter class.

Grind your character up to Level 10, then locate Enok inside the Barracks to acquire your class tome.

Consume the tome from your inventory to permanently adopt the Fighter class and pop the achievement.

Becoming a Mystic

Transform your character into the spellcasting Mystic class.

Reach Level 10 and visit Angela standing near the world portal to collect the Mystic class tome.

Read the tome to become a Mystic, immediately awarding the unlock.

Becoming a Bandit

Dedicate a character to the agile Bandit archetype.

Upon hitting Level 10, speak to Sally at her shop counter to obtain the Bandit class tome.

Activate the item to switch your path to Bandit and complete the achievement.

Keep in mind that these class tomes are tied to specific story assignments offered by their respective patrons:

• Devious Pact — Offered by Sally
• Strength and Honor — Offered by Enok
• Disciple of Magic — Offered by Angela

Once you accept the associated quest, open your bags, navigate to the Consumables tab, and use your new book.

If you enjoy personalizing your character while exploring the hub, experimenting with social commands and emotes adds plenty of charm between dungeon delves.

Clearing Catacombs (12-18)

Conquer the high-level variant, Sanctum Catacombs (12-18).

Enter through the portal in Outer Sanctum and fight your way to the final depths.

You must defeat Lord Kaluuz at the culmination of the run. The achievement will register only when the boss falls.

Clearing Grove (15-20)

Survive and complete the introductory forest expedition, Crescent Grove (15-20).

Journey over to Crescent Keep to find the staging area and entrance for Crescent Grove.

Work through the encounters in the 15-20 bracket to claim your completion credit.

Clearing Grove (20-25)

Clear the final endgame dungeon route, Crescent Grove (20-25).

Step through the high-tier portal accessible inside Crescent Keep.

Conquering the Crescent Grove (20-25) instance puts an end to the core dungeon checklist, granting this milestone achievement.

ATLYSS Subclass Achievements

Once you gain access to Crescent Grove, look for Cotoo, the Badge Merchant dealing in Level 20-25 equipment.

Cotoo offers subclass specialization manuals priced at 2 Windcore Badges apiece.

Purchasing and using these tomes unlocks three distinct subclass achievements: Paladin, Magus, and Bishop.

You can farm the required Windcore Badges by slaying the boss Valdur located inside the Crescent Grove (20-25) dungeon.

Judgement

Attain the holy Paladin subclass on an active Fighter character.

Purchase the Tome of the Paladin from Cotoo and consume it while playing as a Fighter.

This transforms your warrior into a Paladin, unlocking Judgement instantly.

Corrupted Arcana

Adopt the offensive Magus subclass on an established Mystic.

Acquire the Tome of the Magus from Cotoo and use it directly on your Mystic character.

Upon activation, the Magus subclass becomes active and rewards this achievement.

Holier than Thou

Specialize into the divine Bishop subclass as a Mystic.

Buy the Tome of the Bishop from Cotoo and activate it while logged in as a Mystic.

Embracing the Bishop role fulfills the requirement and triggers the unlock.

Miscellaneous Achievements

Fashion Sense

Add any single piece of cosmetic vanity equipment to your personal inventory.

Cosmetic items drop randomly from treasure chests scattered across the various dungeons.

You can also grab the complete Bunhost cosmetic set right in the central hub. Pieces are hidden on top of Angela’s Tower and tucked behind the Barracks, which you can access by leaping across from the tower roof.

Picking up any valid vanity piece will fulfill Fashion Sense immediately.

Altered Vision

Reroll or modify your hero’s appearance using the Mirror of Illusion.

Enter Angela’s Tower and slip into the rear area positioned directly behind the world portal.

Interact with the Mirror of Illusion while holding an Illusion Stone to alter your visuals and secure the unlock.

Teaming Up

Form or join an active group alongside a fellow player in online multiplayer.

Connect to any online session and team up with someone in your lobby.

Send an invite out to another adventurer or accept an incoming request. If the achievement fails to pop when joining, host the group yourself instead.

Trout Master

Purchase and own the prestigious Fisher’s Overalls gear piece.

Make the trek over to Torta’s Fishing Shack and speak directly to Torta to inspect the merchandise.

Purchasing the overalls requires trading in a hefty stack of 99 Sugshrimp.

Expect a dedicated grind here, as current game versions offer no fishing buff gear and unwanted fish will frequently bite. Be patient while accumulating the required haul.

Handing over all 99 Sugshrimp to finalize the purchase awards the achievement on the spot.

ATLYSS Hidden Achievements

Scaling the Tower

Scale the interior structure to stand atop Angela’s Tower within Sanctum.

You can reach the summit cleanly by timing jumps across the protruding library bookcases.

Advanced mobility skills are completely unnecessary, meaning you can achieve this feat at Level 1 as soon as you spawn.

Scaling Stars

Complete the vertical platforming gauntlet inside the Trial of the Stars.

This trial exists as an open-world zone that can be entered from the Wall of the Stars.

The zone features a daunting vertical tower demanding precise parkour leaps. Reaching the final platform at the summit triggers the achievement.

If the portal appears inactive, speak with Craig at the Wall of the Stars to accept his quests, which properly activates the trial teleporter.

Rude!

Provoke the patience of Angela Flux until she retaliates.

Wait near Angela in her tower until she leans over to collect a book from the floor.

While she is bent over, strike her using your primary attack (Left Click / M1). She will lash out in irritation, knocking your character backward.

This achievement previously suffered from hit detection glitches in early game builds. Equipping a melee weapon makes registering the hit far more reliable than using unarmed strikes.

Smaller player models like imps often struggle to align with her strike box, so equip an extended melee weapon to ensure your strike connects cleanly.

Skill Student

Study and master 12 unique Novice Skills across your journey.

To meet the criteria, you must actively learn 12 Novice Skills directly from Skill Scrolls.

These teaching scrolls can be discovered as overworld loot, pulled from dungeon chests, or bought from local vendors.

Take note that baseline Novice Skills granted freely upon selecting your class do not count toward this total. Every single entry must be consumed from an external scroll.

You do not have to unlearn existing powers to make artificial room for new scrolls. Reading the scrolls sequentially satisfies the counter.

While characters carry a ceiling of 36 skill points, purchasing a Tome of Unlearning is unnecessary here. The achievement simply tallies cumulative scroll activations.

If the achievement has not triggered after 12 unlocks, double-check your spellbook to verify that all learned skills originated from physical scrolls rather than your starting class kit.
