How to Unlock Thragg in Rogue Piece
The Thragg unlock process follows a structured questline on the Invincible City island. Each step builds upon the previous one, requiring both persistence and combat skill to complete.
| Step | Quest Objective | Requirement | Difficulty |
|---|---|---|---|
| 1 | Talk to Acquaintance NPC | Reach Invincible City | Easy |
| 2 | Perform 500 M1 attacks | Hit the training dummy | Medium |
| 3 | Get Enlightened | 1 in 500 chance per M1 | Hard |
| 4 | Kill 25 Filthrimites | Spawn every 2-3 min in city | Medium |
| 5 | Kill 5 Thragg bosses | Requires Viltrumite drops | Hard |
| 6 | Unlock Mastery (F move) | Kill 15 Thragg bosses | Very Hard |
Travel to Invincible City
Locate the new Invincible City island on the map. This is the primary hub for all Thragg-related content. Once there, find the Acquaintance NPC to begin the questline.
Complete the M1 Training
Use basic combat to perform 500 M1 attacks on the training dummy. This is a straightforward grind but takes time. Each hit has a chance to trigger Enlightenment.
Achieve Enlightenment
Enlightenment is a rare proc with a 1 in 500 chance per M1 attack on the dummy. Keep attacking until it triggers. This is the most RNG-dependent step in the questline.
Defeat 25 Filthrimites
Filthrimites spawn in Invincible City every 2-3 minutes. Clear them efficiently by waiting at spawn points. This step tests your sustained combat ability.
Spawn and Kill Thragg Boss (5x)
Use Viltrumite drops obtained from Filthrmite kills and Conquest mode to spawn the Thragg boss. Defeat him 5 times to unlock the base Thragg weapon and abilities.
The Enlightenment step is pure RNG with a 1 in 500 chance per M1. Some players get it within the first 500 hits, while others may need over 1,000. Stay persistent and keep attacking the dummy until it procs.

Viltrumite Drop Farming Strategies
Viltrumite drops are the primary gating resource for unlocking and mastering Thragg. Understanding the most efficient farming methods will dramatically reduce your total grind time.
| Source | Drop Rate | Spawn Frequency | Recommended Strategy |
|---|---|---|---|
| Filthrimites | Moderate | Every 2-3 min | Camp spawn points |
| Thragg Boss | High | Player-spawned | Use spawner NPC |
| Conquest Mode | Half drops | On-demand | Supplement boss kills |
The most efficient approach is alternating between Filthrimate spawns and Conquest mode. While waiting for Filthrimites to respawn, run Conquest content for supplemental drops. Save all Viltrumite materials for Thragg boss spawns rather than spending them elsewhere.
Viltrumite Farming Goals:
- Camp Filthrimate spawn points in Invincible City
- Run Conquest mode between spawns for half drops
- Save all Viltrumite drops for Thragg boss spawns
- Track kill count toward 5 base + 15 mastery kills
- Coordinate with other players for faster boss kills
Thragg vs Yhwach Comparison
Both Thragg and Yhwach were released in the same update, and players frequently debate which is the better investment. Based on damage testing and overall utility, here is how they compare.
| Category | Thragg | Yhwach |
|---|---|---|
| Unlock Difficulty | Hard (RNG heavy) | Hard (Boss grind) |
| Location | Invincible City | Forsaken Society |
| Damage Output | High | Very High |
| AoE Coverage | Good | Excellent |
| PvP Viability | Strong | Strong |
| Farming Speed | Moderate | Fast |
| Overall Rating | ★★★★☆ | ★★★★★ |
Based on current testing, Yhwach edges out Thragg in overall damage output and utility. However, Thragg remains a top-tier choice with devastating burst damage. If you can only pursue one, Yhwach is the slightly stronger pick, but both are well worth the investment.
