Where Gene Rolls come from

GENESPART2 and SORRYFORBUGS each list 5 rolls. JUANMOREGENEROLL lists 1. SorryForRestart lists 5. Those rows are on codes.

The Part 2 notes add three more sources: a daily login that pays the most on day 7 (4 rolls), a shop stock of 10 rolls that resets on Saturday, and playtime rewards. Pity on the old panel showed Legendary at 75 rolls and Mythic at 150.

Slots and the four effects that were printed

Slot 1 is free. Slot 2 costs $50,000 cash. Slot 3 costs R$199. I am copying those prices from the panel capture, not from a shop guess.

Endurance prints +8% strength gains, +10 max stamina, +12% stamina regen, +8% stamina saved, +2% height, and −3% muscle size. Ironbone prints +45% strength gains, thicker limbs, and the Heavy Frame ability: extra gains on leg and back work, with every 20th rep doubling the next one. Titan Genome was reworked in Part 2 to +170% gains, less stamina, and Aftershock, which refills stamina when you hit empty. Aeon Heart builds gains and rep speed across a set, makes every 4th rep free, and lights the chest.

The other eleven genes have a name and, for the original twelve, a chance. Their effect cells stay blank. Silverback, Pack Instinct, and Aeon Heart have no published chance after they were added.

FAQ

What is the rarest gene?

Titan Genome was listed at 0.2% on the pre-Part-2 panel and is labeled Secret. Aeon Heart is also Secret, with no new chance printed.

Do the old percentages still add up?

They described 12 genes. Part 2 added three and the mini-update rebalanced all 15. I do not have a newer chances panel, so I did not invent new odds.
