Rare badge mechanics without fake precision
Divine Fortune
Trigger: High-tier luck or rare-event achievement condition
Model: Exact trigger not reproducibly verified
Do not publish a precise chance or expected attempts without the achievement panel and source evidence.
Ztrifecta
Trigger: One Stat Reroll produces Z in Damage, Range, and SPA simultaneously
Model: If each slot has independent Z probability p, joint chance is p³
Enter a verified per-slot Z rate before using the result as a resource forecast.
Probability rules
- For independent events, at-least-once chance after n attempts is 1 − (1 − p)^n.
- A joint three-slot event is p × p × p only if slot rolls are independent and use the same p.
- A zero recorded unlock count is not proof that the underlying probability is exactly zero.
