Legacy Piece has released Part 1 of its Halloween update, bringing new content to the game, including Sosuke Aizen from Bleach and Castel Ree. Among the new additions, TYBW Aizen stands out because of his powerful weapon skills, counter mechanics, and high damage output.
Getting the new Aizen weapon requires completing several quests, defeating multiple bosses, and collecting special materials. The process starts at Quincy Castle, where the Shunsui NPC gives you the quests needed to unlock the weapon and its additional skills.
How to Get TYBW Aizen in Legacy Piece
Before starting, make sure you have Aizen V1 and that it is fully enchanted. A weapon-focused build is recommended because most of the quests require you to defeat bosses while using Aizen V1.
Head to Quincy Castle and talk to the Shunsui NPC to begin the Prisoner of Muken questline.
Quest 1: Defeat the Aizen Boss
For the first quest, you must use Aizen V1 to defeat the Aizen boss on Hollow Island.
The requirements are:
- Defeat the Aizen boss 60 times.
- Collect 10 Kyoka Suigetsu Echo.
You can complete this quest on Normal difficulty to make the farming process easier. Setting up your skills to activate automatically can also help you finish the required boss kills faster.
Make sure Aizen V1 is equipped while completing the quest, as the weapon requirement is part of the objective.
Quest 2: Defeat the Ichigo Bankai Boss
After finishing the first quest, return to the questline and take on the next challenge. This time, you need to fight the Ichigo Bankai boss.
The requirements are:
- Defeat the Ichigo Bankai boss 20 times.
- Collect five Hogyoku Resonance.
Continue farming the boss until you have enough kills and materials. Keep checking your quest progress so you know when both requirements have been completed.
Quest 3: Defeat the TYBW Aizen Boss
The final quest in the Prisoner of Muken questline requires another visit to the Shunsui NPC. You will need to fight the Aizen Thousand-Year Blood War boss and defeat him while using Aizen V1.
There is one important restriction: you cannot switch weapons during the fight.
Once you complete this final challenge, you will receive the new Aizen weapon and the Unshackled title. However, unlocking the weapon is only the beginning, as additional quests are needed to unlock its remaining skills.
How to Unlock All TYBW Aizen Skills
After obtaining the weapon, you must continue the questline to unlock its full moveset. The next part includes challenges involving the Quincy King, Sternritters, and the TYBW Aizen boss.
Quest 4: Standing Against the Almighty
For this quest, you must defeat the Quincy King in two locations: Quincy Castle and the Warwelt dungeon.
To summon the Quincy King at Quincy Castle, follow these steps:
- Defeat Quincy enemies to progress toward spawning the Sternritters.
- Every 50 Quincy kills allows you to spawn one Sternritter.
- Defeat all five Sternritters.
- Fight the Quincy King after completing the required encounters.
- Repeat the process until you have defeated the Quincy King five times, as required by the quest.
The Warwelt dungeon requires a separate boss encounter. You can obtain the key needed to access it from the Quincy King boss.
The Warwelt fight is more challenging, so make sure your weapon and stats are prepared before entering. Completing this quest unlocks Aizen’s Hado Number 90 skill.
Quest 5: Defeat the TYBW Aizen Boss Again
The final quest requires you to return to the Shunsui NPC and fight the TYBW Aizen boss again.
You must complete the following objectives:
- Defeat the TYBW Aizen boss 10 times.
- Collect 30 Suppressed Reiatsu.
- Obtain the Unbound title from the boss.
Keep farming the boss until you have collected all the required materials and completed the kill count. Once everything is finished, you will unlock the remaining rewards and complete the Aizen questline.
TYBW Aizen Skills and Passive Abilities
The new Aizen weapon has a set of skills built around stacking effects and counterattacks. Its first three skills can generate stacks, making them an important part of the weapon’s combat mechanics.
After reaching five stacks, Hado Number 90 becomes an enchanted version. This gives players an additional payoff for using the weapon’s skills in the correct order.
Aizen’s F move also features a counter mechanic. It can counter an initial stack interaction and potentially allow further counters against enemy moves. This makes the weapon useful for players who want both offensive pressure and defensive options.
The weapon’s visual effects are another highlight. Its animations give the skills a distinct appearance, making the moveset stand out during boss fights.
Why TYBW Aizen Is So Powerful
TYBW Aizen can deal heavy damage without requiring an overly complicated rotation. Its stack mechanics, enhanced Hado Number 90, and counter ability provide several ways to pressure enemies.
During boss fights, the weapon can eliminate enemies quickly when paired with a suitable build. The showcase demonstrated strong damage even without fully optimized defense penetration gems.
For the best results, consider improving your weapon enchantments and choosing gems that support your preferred damage setup. While the weapon is already powerful, the right stats can make it even more effective against tougher bosses.
TYBW Aizen is one of the major additions in Legacy Piece’s Halloween update, offering a powerful weapon with strong damage, unique stack mechanics, and counter abilities. To unlock it, obtain fully enchanted Aizen V1, complete the three Prisoner of Muken quests, and continue through the Quincy King and TYBW Aizen challenges to unlock the remaining skills.
If you want to use Aizen’s full moveset, be prepared to farm several bosses and collect the required materials. Completing the entire questline gives you access to the weapon’s additional abilities and its full combat potential.
