Total Material Cost Summary

|---|---|---|
| Normal Both Slots | 50 Parts + 50 Docs | Very High (30% each, weapon can be destroyed) |
| High Both Slots | 250 Parts + 250 Docs | None (100% success) |
| High Slot 4 + Special Slot 3 | 250 Parts + 2500 Docs | None + Choose Memory |
Tips
💡 Tip: Slot 4 must be enchanted first — Cannot enchant Slot 3 without Slot 4
Normal tier is very risky — 30% success means expect ~3 attempts, and Slot 4 failure destroys weapon
High tier recommended — 250 materials for guaranteed success is worth it
Special tier for perfect builds — 2500 documents lets you choose your Memory
Material exchange available — Convert between Parts and Documents for 50k Zeny each
