| Ores (N) | P(Coffin's Lid) no lock | Expected forges | With RNG lock |
|---|---|---|---|
| 43 | 5.9% | ~1 in 17 | needs 50 ores |
| 50 | 11.8% | ~1 in 9 | ~1 in 4 locked |
| 55 | 16.1% | ~1 in 7 | ~1 in 4 locked |
"Expected forges" = 1 ÷ combined probability of rolling the class and this variant. RNG lock removes the class roll once N ≥ 50, leaving only the 26.3% variant roll.
Solved at the Forgotten Kingdom anvil with RNG lock targeting the Colossal Sword class — BiS god-roll, clean zero-waste split, and a no-raid farmable fallback.
