About this mod Author’s original text
Repentance Cards
The Binding of Isaac items as ROUNDS cards. Lose a round, pick an item, and build Isaac-style synergies in 1v1 (or more) fights with your friends.
Works great alongside BindingOfRounds (jimbo797), which adds Sad Onion, Brimstone, Polyphemus, Dead Cat and more. Items from both mods count toward transformations.
ROUNDS version: like most mods, this needs the mod branch of the game.
Steam → right-click ROUNDS → Properties → Betas → choose old-rounds-for-mods.
Characters (13)
The first pick of every game is a character select. Each character has their Isaac stats and starting items:
| Character | Playstyle |
|---|---|
| Isaac | Balanced, starts with a random item (the D6) |
| Magdalene | +50% health, slower, starts with Yum Heart |
| Cain | Fast, +20% damage, +1 ammo, fragile |
| Judas | +35% damage, -40% health, starts with The Book of Belial |
|??? | Soul hearts: more health and speed |
| Eve | Starts with Whore of Babylon, weaker until hurt |
| Samson | Starts with Bloody Lust |
| Azazel | Flies, huge close-range damage, weak at range |
| Lazarus | An extra life |
| Eden | Random stats and a random item |
| The Lost | Flies, spectral tears, Holy Mantle every battle, but dies in one hit |
| Lilith | Two Brother Bobby familiars do the fighting |
| Keeper | Triple shot, low health |
If you own Isaac, your player wears the character's head in-game (built from your own copy of the game). Turn the character select off with CharacterSelect = false in the config.

Card art
This mod does not contain any art from The Binding of Isaac. If you own Isaac on the same PC, the mod uses the item sprites, character portraits and character heads from your own copy: on first launch it runs Isaac's own ResourceExtractor (in your Isaac folder under tools) to unpack them, which can take a minute. Without Isaac, the cards use the mod's own icons. Art is cosmetic and per-PC, so players with and without Isaac can pla
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.
Install these first, or the mod will not work:
