Tinted Rocks[]

Tinted Rocks Repentance

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 WombWomb, UteroUtero, and (except in Rebirth)Scarred WombScarred 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 (in Afterbirth † and Repentance)[]

Repentance super special rocks

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 Collectible The Small Rock iconThe Small Rock appear without extra rewards.

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 the achievement 5 Nights at Mom's 5 Nights at Mom's, which requires getting a 5-win streak, using a different character each time. (in Repentance) This number can be reduced to 3; see the Notes section of the Achievements page.

Bomb Rocks[]

Bomb Rock

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 (in Repentance)[]

Spiked Rock

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 Pressure PlatePressure Plates, after all the plates 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.

Flat FileFlat File will remove the spikes from the rocks.

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

Found in:

Notes[]

  • If a Spiked Rock is used to fill in a gap, stepping on the created spiked path will deal a full heart of damage. This damage is considered self-damage (it will not affect Angel/Devil Deal chances and items such as (in Repentance)Collectible Paschal Candle iconPaschal Candle). Touching Spiked Rocks, however, will not count as self-damage.
