Overview

The Boss Rush room is a room-type similar to that of the Devil Room in The Binding of Isaac: Rebirth. It will spawn after defeating Mom in The Depths or Necropolis in under 20 minutes since the start of the game. It appears similar to the entrance to a secret room, but the hole is much larger and eminates a red glow similar to a boss room.

Completing this room is one of the six goals shown on the character select screen, appearing in the middle as a star when completed.

If Mom was a Champion Boss, all Bosses in the room may have a chance of being in Champion form. While it is not a definite, keep this in mind before attempting this challenge.

If you're doing a challenge or playing on a seed and beat the Boss Rush room you will not be rewarded a with the Star Completion Mark.

b=Beating the Boss Rush unlocks a different item depending on which character beat it.

Description

The room is a 69x69 room.

There are 4 items in the center. They are generally rare items.

In Afterbirth, there may be only two items to choose from. Also, items might be blocked by rocks or spikes.

When you take one item, the others disappear, and the Boss Rush begins.

After finishing Boss Rush, you earn an additional item.

An exploit can be done using a teleporting tarot card when in the room, picking up an item and when the bosses spawn, using the item will take you to a certain location (depending on card) and let you keep the item.

If the teleport card is used immediately upon picking up an item it is possible to make your way back to the Boss Rush room to pick up a second item.
