Arcana Basement

An experimental solo mashup for base The Binding of Isaac: Rebirth and Wizard of Legend. Requires both installed Steam games.

Play a Wizard of Legend wizard in Isaac's native dungeon. Cast Fireball with the arrow keys, dash with Shift, and unleash an eight-shot Flame burst with Q. Isaac's rooms, enemies, bosses, drops and items remain, and spell damage and casting speed follow Isaac's current stats. Space keeps Isaac's active-item control.

The first version includes one wizard, two fire attacks, and two adapted relic rewards: Neve's Ruby after two room transitions (+20% spell damage) and Leemo's Leaf after four (25% faster dash cooldown). Relic rules are mashup adaptations; special Isaac weapon conversions may differ from the original game. Mod relics reset when the mod restarts.

The companion reads the wizard and Fireball icon directly from the player's installed Wizard of Legend into memory. No assets from either game are redistributed or extracted to disk. Native integration targets base Rebirth Steam build 20115169; other Isaac editions are not supported.

Original code is MIT and remixes are welcome. Complete source is included. The combined native component also follows GPL-2.0 because it uses Omni's Isaac Injector signature data; MinHook is BSD licensed. Full notices are bundled.
