Starting combat stats
Values before collectibles, temporary effects, and most character mechanics. Comparison labels use Isaac's standard 1.00 speed, 2.73 tears, 3.50 damage, 6.50 range, 1.00 shot speed, and 0.00 luck as the baseline.
- Speed
- 1.30 Above baseline
- Tears / sec

- Damage
- 4.20 Above baseline×1.2 damage multiplier
- Range
- 4.50 Below baseline
- Shot speed

- Luck

Character note: Lucky Foot raises Cain's effective starting luck to 1.00. The card shows the underlying base value so it remains comparable with the rest of the roster.

Character-selection and achievement art are from the extracted Repentance files. Starting health, pickups, and items reflect the base player records with reviewed special-character conversions. Combat stats use reviewed Repentance 1.7.9b references because those values are hardcoded and absent from the player XML. Unlock conditions and the additional rewards use reviewed Repentance achievement records and completion references. Repentance+ may differ.
