BoI Four Souls: Undertale Expansion

* The Basement has gone even deeper, opening up a path to the Underground, where monsters, friendly or hostile, have joined in. Seeing these new friends and enemies fills Isaac with Determination.

Welcome to (yet another) Binding of Isaac: Four Souls expansion mod, which adds a grand total of 368 original Undertale-based cards. Play as the coolest of all skeletons, fight the King of Monsterkind, do a... dating fight? And more!

The expansion adds 28 new characters, each with their eternal items, 70 items, 101 monsters (including 20 bosses), 17 events/happenings, 17 rooms and 52 different loot cards that have all been inspired from the game "UNDERTALE", which you should probably play before using this expansion, there's spoilers.

You can use the expansion by saving the main bag as an object, then using it on any Four Souls table you use.

Hopefully you'll enjoy your journey through the Underground, and stay determined along the way to gain four souls.

A good chunk of the sprites were taken from UNDERTALE by Toby Fox, and again, you should support the original game: https://undertale.com/

A doc with all the cards if you wanna print them, I have no idea how printing cards works, but here you go:

And last but not least: Thank you to Toast for basically giving more than half the card ideas, and the people of the Four Souls Discord server for helping out with the balance of those ideas. Ezim, you're one hell of a cool dude.
