🎯 How to Get Split Soul Katana

Method 1: Soul Curse Boss Raid (0.25% Drop)

The Soul Curse is an endgame boss raid that requires a coordinated team. Defeating it grants a 0.25% chance to drop the Split Soul Katana — one of the lowest drop rates for any weapon in the game.

Recommended Level: 400+

Team Size: 4-player squad recommended

Respawn Timer: 45 minutes

Expected Farm Time: ~40-80 hours of dedicated farming

⚠️ Persistence Required: At 0.25%, you need roughly 400 kills to reach the expected value. This is a marathon, not a sprint.

Method 2: Zen Forest Crafting (100 Transfigured Humans)

The deterministic path. Collect 100 Transfigured Humans and bring them to the Zen Forest forge station for guaranteed crafting.

Crafting Steps:

  1. 1. Farm Transfigured Humans from Investigation missions
  2. 2. Accumulate 100 in your inventory
  3. 3. Travel to Zen Forest (northeast map region)
  4. 4. Find the forge anvil near the large tree
  5. 5. Select "Split Soul Katana" recipe
  6. 6. Confirm synthesis

Recommended: While 100 Transfigured Humans takes significant farming, this is the guaranteed path with no RNG.

Method 3: Trading

If you have high-value items, trading is the fastest acquisition method. Check current rates on our Trade Value List.

📉 Balance History & Value Impact

Recent Nerf: Burst damage reduced in latest patch. Trade value temporarily dropped ~20% before stabilizing.

Current Status: Despite the nerf, Split Soul remains a top-3 weapon due to its sustained DPS and bleed mechanics. Value has recovered to ~85% of pre-nerf levels.

💡 Investment Tip: Post-nerf weapons often recover value over time as the community adjusts builds. This could be a buying opportunity.
