Yhwach Overview & Video Showcase
Yhwach is one of the newest and most powerful additions to Rogue Piece, introduced in the latest major update alongside Thragg. Located on the Forsaken Society island, this character brings an incredibly potent moveset that scales exceptionally well in both PvE and PvP encounters. To obtain Yhwach, players must navigate a multi-stage questline, collect rare boss drops, and invest significant time into farming specific enemies.

Before heading to Forsaken Society, ensure you have enough Reatsu to spawn bosses. The Aizen Thousand Year boss in particular requires a substantial Reatsu pool. Stock up on resources and bring a strong loadout to handle the 50 Aizen kills efficiently.
Questline Breakdown & Requirements
The Yhwach questline is initiated by speaking with the Acquaintance NPC on Forsaken Society island. This NPC serves as the central hub for all progression related to unlocking the Yhwach weapon and its associated items. The questline is divided into four distinct phases, each requiring you to defeat specific bosses in set quantities.
| Quest Phase | Target Boss | Kill Count | Spawn Location | Notes |
|---|---|---|---|---|
| Phase 1 | Aizen | 50 | Forsaken Society | Standard boss, moderate difficulty |
| Phase 2 | Aizen Thousand Year | 25 | Forsaken Society | Requires high Reatsu to spawn |
| Phase 3 | Quincy | 25 | Forsaken City | Spawns every 2-3 minutes |
| Phase 4 | Yhwach | 5 | Forsaken Society | Requires Quincy Souls to spawn |
The Aizen Thousand Year boss demands a significant amount of Reatsu to spawn. If you run low, farm lower-tier enemies or participate in raids to replenish your reserves before attempting Phase 2. Running out mid-farm can stall your entire progression.
Boss Spawn Mechanics
The Quincy boss spawns naturally in Forsaken City on a 2-3 minute timer. This boss is essential for two reasons: completing Phase 3 of the questline and dropping Quincy Souls needed to spawn Yhwach himself. The Yhwach boss does not spawn naturally and must be manually summoned using the Spawner NPC on the island.
| Resource | Source | Drop Rate | Purpose |
|---|---|---|---|
| Quincy Souls | Quincy Boss | Moderate | Spawning Yhwach boss |
| Yhwach Drops | Yhwach Boss | Guaranteed | Purchasing Yhwach weapon |
| Reatsu | Various enemies | Variable | Spawning Aizen variants |
Step-by-Step Unlock Guide
Follow this sequential process to unlock Yhwach from start to finish. Each step builds on the previous one, so do not skip ahead.
Travel to Forsaken Society
Navigate to the new Forsaken Society island. Locate the Acquaintance NPC among the cluster of NPCs and interact to begin the questline. This NPC will track your progress through all four phases.
Defeat 50 Aizen Bosses
Farm the standard Aizen boss fifty times. This is the most time-consuming phase but serves as a Reatsu-building opportunity. Use efficient combos and minimize downtime between spawns.
Defeat 25 Aizen Thousand Year Bosses
This variant requires substantial Reatsu to spawn. Monitor your Reatsu levels carefully and take breaks to farm if needed. Twenty-five kills are required to advance.
Defeat 25 Quincy Bosses
Head to Forsaken City where the Quincy boss spawns every 2-3 minutes. Collect Quincy Souls from each kill, as you will need them for the final phase. Twenty-five kills complete this stage.
Defeat 5 Yhwach Bosses
Use the Spawner NPC on Forsaken Society to summon Yhwach using your collected Quincy Souls. Defeat him five times. Once completed, you can purchase the Yhwach weapon.
After completing all five steps and purchasing the Yhwach weapon, your next goal is unlocking the F move mastery. Speak to the Awakener NPC to begin the mastery quest.
Mastery, Accessories & Clans
Unlocking the Yhwach weapon is only the first half of the journey. To maximize its potential, you need to unlock the F move through the Awakener NPC and acquire the matching accessory and clan bonuses released in the same update.
Mastery Unlock
The Awakener NPC offers a single-step quest: defeat 15 Yhwach bosses. This is a significant investment given the Quincy Soul cost per spawn, but the F move dramatically increases your damage output and combat versatility.
| Upgrade | Requirement | NPC | Reward |
|---|---|---|---|
| Base Weapon | Complete 4-phase questline | Acquaintance | Yhwach weapon purchase |
| F Move Mastery | Kill 15 Yhwach bosses | Awakener | Unlocks ultimate F move |
| Accessory | Update release content | Various NPCs | Stat bonuses |
| Yhwach Clan | Clan gacha/reroll | Clan system | Passive buffs |
When farming the 15 Yhwach kills for mastery, stockpile Quincy Souls in advance. Each Yhwach spawn consumes Souls, and running out mid-quest means backtracking to farm the Quincy boss. Aim for at least 20-25 Souls before starting the mastery grind.
Yhwach vs Thragg Comparison
The update introduced both Yhwach and Thragg simultaneously. Here is how they compare across key categories:
Yhwach
- Superior raw damage output
- Clean, fast weapon animations
- Strong PvE and PvP performance
- Questline based on Forsaken Society
- Requires Quincy Soul farming
Thragg
- Solid damage with unique moveset
- Based on Invincible City island
- Requires 500 M1 attacks on dummy
- One-in-500 enlightenment chance
- Viltrumite drops from conquest
Based on damage testing, Yhwach generally outperforms Thragg in most combat scenarios. The cleaner animation set and higher burst damage make Yhwach the preferred choice for players who can only invest in one. However, Thragg offers a more accessible entry point for players already progressing through Invincible City content.
