How chase math works

The formula is n = log(1 - P) / log(1 - p), where P is your target probability and p is the single-pull drop rate. Multiply n by the pack cost to get the token budget.

A 50% chance is the "coin flip" threshold — you are as likely to succeed as not. A 90% chance is a strong bet but still fails 1 in 10 times. A 99% chance is near-certain but extremely expensive for ultra-rare blooks.

These numbers assume no duplicate resell. Enable resell in the main calculator for effective-cost-adjusted budgets.
