Tinted Rocks[]

Tinted Rocks Repentance.png

Sometimes referred to as "Marked Rocks", they are always marked with an "x", and in some levels slightly tinted/discolored. These rocks are much less noticeable in Womb Womb, Utero Utero and Scarred Womb Scarred Womb due to them being the same color as the surrounding rocks, but can still be distinguished by the "x" on the bottom right. Only one tinted rock can spawn per room.

Found in: Every Stage

Tinted Rocks have a chance to spawn 1-3 of the following when destroyed:

Super Special Rocks Added in Afterbirth †[]

Repentance super special rocks.png

Super Special Rocks are Tinted Rock variants whose smaller marks and lack of discoloration make them much harder to spot. Super Special Rocks take two bombs to blow up and drop the contents of two Tinted Rocks, with the exception that a single chest or The Small Rock The Small Rock appear without extra rewards.

  • Added in Repentance The first super special rock encountered will always spawn The Small Rock The Small Rock, if it hasn't already been generated.

Only one super special rock can spawn per room, and normal tinted rocks cannot appear in the same room.

In Chapter 4 and Chapter 4.5 Super Special Rocks are almost identical to Tinted Rocks, making them easier to spot in these chapters.

Super Special Rocks are unlocked by .Added in Afterbirth †5 Nights at Mom's Get a 5-win streak (Added in Repentance 3-win streak), using a different character each time

3 win streak only counts on hard. You still need a 5 win streak on normal.

Added in RepentanceNote: Using normal Characters to get a win and then using its tainted counterpart won't work, only one of them will work for obtaining the achievement.

Added in RepentanceNote: The achievement does not unlock in Co-op Repentance even if the three wins were done with different characters for each player.

Regardless of DLC version, an unlocking streak must be done with unique characters. That means each successful run must be performed with a new character for it to qualify.

Bomb Rocks[]

Act like rocks.

Found in: Small chance of replacing any rock on any chapter.

Bomb rocks can be found anywhere a normal rock can spawn. They can only be destroyed by explosions and "stompy" items, like normal rocks. When they are destroyed, they create an explosion. Note that destroying a bomb rock next to a hole does not create a bridge as with normal rocks.

Spiked Rocks Added in Repentance[]

Spiked Rock.png

Spiked Rocks are variants of normal rocks which hurt Isaac on contact, even if he's flying. They can fill in a 1-block wide gap like ordinary rocks, but the spikes will remain and Isaac will take damage as he steps on them. If they are located in a room with Silver Button Silver Button, after all are pressed, the spikes will retract into the interiors of the rock. If a Crawl space is generated with the same rock used to fill a gap, the bridge will not be spiked.

Added in RepentanceFlat File Flat File will remove the spikes from the rocks.

If spiked rocks are crushed by being Stompy, having Leo Leo or Thunder Thighs Thunder Thighs, or using The Nail The Nail, they do not always deal damage, depending on Isaac's speed, size and the angle touched from.
