Pet Reroll Calculator

Estimate the chance to hit a chosen secondary stat over several rerolls, and total diamond spend. HP vs All XP uses the same odds — only the line you reroll changes.

Inputs

Same list as Database → Pets — names, stat lines, and source match the wiki table. Your pet’s Tier (below) is progression, not in that static list.

Notes

  • Set N to match how many equally likely secondary outcomes exist in your situation (e.g. N = 5 → 20% per roll, matching a “Gold multiplier” example).
  • Independent rolls: P(at least one hit) = 1 − (1 − p)ⁿ.
  • Per-tier diamond costs are community placeholders until wired to live values.
