Rerolls
Always changes species, with a rarity-based shot at +1 rarity. Cost and payoff both scale with the creature's own rate, so payback depends only on rarity — every creature of a rarity is the same deal, the cheapest just risks less. Max pity cost assumes the pity counter (3/5/8/12)Pity 3/5/8/12 — what it means
From the game's own config:
upgradeChance: common .2 · uncommon .1 · rare .04 · epic .01 · legendary 0
pity: common 3 · uncommon 5 · rare 8 · epic 12 · legendary 0
The counter counts failures: after N failed rerolls on a creature of that rarity, the next one is guaranteed to promote. So the worst case is N+1 attempts — an uncommon (pity 5) lands on the 6th try at the latest, which matches what play shows.
Max Pity Cost prices every reroll at that worst case: N+1 attempts at full price. It is the only figure you can actually budget against, and it is what this tool uses by default.
RNG Averages prices it at the expected number of tries instead — cheaper on paper, but you can and will run past it:
rarity odds pity max tries avg w/pity avg no pity
common 20% 3 4 2.95 5
uncommon 10% 5 6 4.69 10
rare 4% 8 9 7.69 25
epic 1% 12 13 12.25 100
is a hard guarantee; that's server-side and unverified, and without it rare/epic are ~3.6×/8.8× worse.
