Enter Stellar Jade, Special Passes, pity, and guarantee — then see the chance your budget covers E0, E0S1, or higher. Monte Carlo with approximate soft pity; planning only.
Absolute worst case for one featured character (lose 50/50 + two hard pity) is 180 pulls / 28,800 Jade. Soft pity makes that rare — use percentiles, not vibes.
