| Ores (N) | P(Thunderhead Mace) no lock | Expected forges | With RNG lock |
|---|---|---|---|
| 12 | 6.8% | ~1 in 15 | needs 18 ores |
| 18 | 6.2% | ~1 in 17 | ~1 in 4 locked |
| 23 | 3.5% | ~1 in 29 | ~1 in 4 locked |
| 55 | 0.0% | ~1 in 804,382,442 | ~1 in 4 locked |
"Expected forges" = 1 ÷ combined probability of rolling the class and this variant. RNG lock removes the class roll once N ≥ 18, leaving only the 27.8% variant roll.
