To start, you must reach the Curse Realm and select the Station Domain stage. This high-level zone requires your character to be at least Level 55. While farming this stage, you are hunting for a rare drop called the Cube Room Portal. This item has a flat 5% base drop chance on all difficulties. Because the drop rate does not increase on harder modes, it is highly recommended to speedrun the Station Domain on Normal difficulty to maximize your clears per hour.

Once you successfully obtain the Cube Room Portal, open your inventory and click on the item. This will instantly teleport you to the secret Cube Room Dimension. Here, you will find the Vergil NPC standing in the center. Interacting with him opens a menu with three options: starting the boss fight, learning how to obtain his fourth ability, or viewing the Yamato quest requirements.

Unlocking the Mythic Yamato weapon requires completing a multi-part questline that tests your combat capabilities and resource management. After speaking with Vergil in the Cube Room, select the "Show Quest" option to begin. The quest requires you to complete five demanding objectives across World 2.

The most time-consuming part of the quest is obtaining the Cyborg Arm cosmetic. This SS-tier cosmetic drops from the Mahito boss or can be crafted using rare boss materials. Additionally, you must defeat three of World 2's hardest bosses: Eizen, Hakari, and Mahito. These fights require optimal gear setups and precise dodging, especially Mahito, who utilizes a purple bar blinding mechanic that slows your movement and locks your skills.

The final requirement is completing 50 dungeons. To complete this passively and quickly, you should run the very first dungeon, Summon Gate, on Normal difficulty. A well-optimized build can clear Summon Gate in under three minutes, allowing you to finish all 50 runs in roughly two hours of active play.

Once unlocked, the Yamato immediately claims its spot at the absolute top of the SSS-tier weapon meta. It is a rapid-cycling blade that allows you to weave seamless M1 basic attacks and skill combos with almost zero downtime. Its area-of-effect (AOE) coverage is vast enough to wipe entire waves, while its single-target burst melts high-difficulty raid bosses.

By default, the Yamato only grants you access to three active skills and its ultimate awakening, Devil Trigger. When Devil Trigger is activated, your character transforms, unlocking two devastating ultimate moves: Hell on Earth and Void Time. These moves deal massive multi-hit damage and grant temporary invincibility frames (i-frames).

However, the true power of the Yamato lies in its secret fourth skill: Doppelganger. To unlock this ability, you must defeat the Vergil boss inside the Cube Room and obtain the Doppelganger Title (a rare 3% to 5% drop). Equipping this title above your head unlocks the fourth move, which summons a dark clone that mimics your attacks and permanently buffs your base damage by two times (x2.0).

To maximize the SSS-tier potential of your Yamato weapon, you must pair it with highly synergized traits, gear, cosmetics, and accessories. A properly optimized build can easily double or triple your raw DPS output during Nightmare-level raids.

The absolute best trait to roll on the Yamato is Superior or Unleashed. Superior increases your attack speed and drastically reduces your skill cooldowns, allowing you to cycle Judgment Cuts continuously. If you are still farming for S-tier traits, Accuracy III (+15% skill damage) serves as an excellent placeholder.

For your active gear slot, Time Stop is the undisputed meta choice. Freezing bosses in place allows you to execute your entire basic attack string and ultimate skill rotation without fear of retaliation. For cosmetics, combining the Cyborg Arm (SS-tier) with Wings (S-tier) provides the best balance of critical strike chance, health, and mobility. Finally, equip the Agris Sword accessory for an additional +75 HP and +20% critical strike chance.

Defeating the Vergil boss in the Cube Room is required to farm the Doppelganger Title and unlock your fourth skill. This boss fight is highly mechanical and punishing for players who attempt to mindlessly button-mash.

Vergil utilizes rapid sword slashes, teleportation, and wide-range Judgment Cuts. During Phase 1, focus on landing quick basic attack strings and immediately dashing sideways (Q) to avoid his counter-attacks. Keeping your camera locked in Shiftlock mode (Ctrl) is essential for maintaining mobility.

When Vergil's health drops to 50%, he enters Phase 2 and activates his own Devil Trigger. His attack speed increases dramatically, and he begins spamming massive circular AOE slashes. During this phase, do not attempt to trade damage. Wait for him to finish his skill animations, use your Time Stop gear to freeze him, and then unleash your ultimate skills for a safe and clean clear.

To help you troubleshoot any issues during your grind, here are the answers to the most common questions regarding the Vergil update and Yamato weapon.
