Card Reading 
Effects
- At the beginning of each floor, spawns 2 portals that each lead to either the Boss Room, Treasure Room, or Secret Room.
- The Boss Room portal is red, the Treasure Room portal is yellow, and the Secret Room portal is blue.
- From Chapter 4 onward, only 1 portal will spawn.
- The portals will disappear once the starting room is left, whether a portal was taken or not.
Notes
- During the Ascent, the portal will spawn in the "starting room" that leads to the next floor.
- Entering the starting room in the Mirrored world will cause the portals to spawn there, leading to the mirror's treasure, secret, or boss room.
- If the run is exited, the portals will not be there upon continuing.
- In (The Void) The Void the boss portal will lead to a random boss, not necessarily Delirium.
- Entering a portal with Curse of the Maze active on the current floor has a chance of teleporting Isaac to a random room instead.
- The Treasure Room portal will not lead to a Planetarium if available, unlike (XVII - The Stars) XVII - The Stars.
