Formula

On failure: item destroyed, ore & fee lost. Restart = buy new item at +start price, retry from +start.
Risky step: C(n) = (ore+fee) + p·C(n+1) + (1−p)·(item + C(start))
Substitute C(n) = aₙ + bₙ·C(start) → C(start) = a_start / (1 − b_start)
Total = item + C(start)  ·  Regular and enriched use their own respective NPC fees.
