| Ores (N) | P(Icebreaker Maul) no lock | Expected forges | With RNG lock |
|---|---|---|---|
| 12 | 6.1% | ~1 in 17 | needs 18 ores |
| 18 | 5.6% | ~1 in 18 | ~1 in 4 locked |
| 23 | 3.1% | ~1 in 32 | ~1 in 4 locked |
| 55 | 0.0% | ~1 in 893,758,269 | ~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 25.0% variant roll.
Solved at the Frostspire Expanse anvil with RNG lock targeting the Mace class — BiS god-roll, clean zero-waste split, and a no-raid farmable fallback.
