| Ores (N) | P(Frostpetal Blade) no lock | Expected forges | With RNG lock |
|---|---|---|---|
| 19 | 5.0% | ~1 in 20 | needs 25 ores |
| 25 | 5.1% | ~1 in 20 | ~1 in 5 locked |
| 30 | 3.2% | ~1 in 32 | ~1 in 5 locked |
| 55 | 0.0% | ~1 in 352,202 | ~1 in 5 locked |
"Expected forges" = 1 ÷ combined probability of rolling the class and this variant. RNG lock removes the class roll once N ≥ 25, leaving only the 23.8% variant roll.
Solved at the Frostspire Expanse anvil with RNG lock targeting the Katana class — BiS god-roll, clean zero-waste split, and a no-raid farmable fallback.
