How Many Rolls Do Pools Last?

Pools mostly shrink every time they are. Because the cap slows down how fast the pool drains, you can count on a few turns before it empties.

Average Rolls Until Empty

6d6~4 rolls3-5 rolls
8d6~5 rolls4-6 rolls

Think of these numbers as guidelines instead of guarantees. Each average wobbles by roughly +/-1 roll in real play. Use the averages to pace long-term threats, doom tracks, or countdown events tied to pools from the rules.
