Infested blocks consist of stone, cobblestone, deepslate, or any stone bricks variants that take less time to break and spawn only silverfish when broken without Silk Touch. Silverfish hide in these blocks, and emerge when a nearby silverfish is attacked in order to attack the aggressor. Infested blocks cannot be obtained in item form.

Obtaining[]

Infested blocks are not obtainable by Silk Touch, and are only available through the Creative inventory or commands. However, they can be retained from worlds played in versions where they were legitimately obtainable.

Breaking[]

Silverfish infest anim

Breaking an infested block by hand. More silverfish appear when attacking the first one.

When the block is broken, whether by a player or by an explosion, a silverfish spawns where it was broken unless the difficulty is Peaceful or the game rule doTileDrops is set to false (doMobSpawning is irrelevant).

Infested blocks take less time to break than their normal counterparts. When breaking them with a pickaxe, they take half as much time to break as their normal counterparts.

When mined with anything other than a Silk Touch-enchanted tool, an infested block drops nothing and spawns a silverfish that immediately attacks the player. If the player attacks a silverfish directly with a sword, bow, or potion of Harming, or when a silverfish takes Poison damage, nearby infested blocks break, spawning more aggressive silverfish. If the silverfish is killed in one hit, then nearby infested blocks do not break, and no silverfish spawn from them.[1]

When mined with a tool enchanted with Silk Touch, however, the equivalent non-infested block is dropped without spawning a silverfish on all game difficulties.[2] Any Silk Touch-enchanted tool (including swords) will cause an infested block to drop its non-infested equivalent (that is, a pickaxe is not required). A player wishing to collect stone bricks from a stronghold safely should use Silk Touch-enchanted pickaxes.

Natural generation[]

Infested stone bricks are occasionally found in strongholds and igloo basements in place of normal stone bricks. Infested mossy and chiseled stone bricks also spawn in igloos, but they do not generate naturally in strongholds.[3]

Infested cobblestone is found in the rarely generated "End portal" room in woodland mansions.

Infested stone and deepslate can generate in the Overworld in the form of blobs. Infested blocks attempt to generate 14 times per chunk in ore features of size 0-13, from altitudes -64 to 63 in Java Edition or 0 to 64 in Bedrock Edition, within one of the following biomes, or within a chunk that is at least partially occupied by one of these biomes:

Infested stone blob can replace stone, andesite, diorite, granite, polished andesite‌‌[BE only], polished diorite‌‌[BE only], polished granite‌‌[BE only], tuff[JE only], and deepslate. If it replaces tuff or deepslate, it becomes infested deepslate.

Post-generation[]

Infested blocks are generated when a silverfish enters the respective normal block form.

Usage[]

When mined, an infested block spawns a silverfish that immediately attacks the player. If the player attacks a silverfish directly with a sword, bow, or potion of Harming, or when a silverfish takes poison damage, nearby infested blocks break, spawning more aggressive silverfish. If the silverfish is killed in one hit, then nearby infested blocks do not break, and no silverfish spawn from them.

Identifying[]

Note blocks placed on infested blocks produce flute sounds‌[Bedrock Edition only] or harp sounds‌[Java Edition only], while those placed on the non-infested stone, cobblestone, or stone bricks produce bass drum sounds.

In Bedrock Edition, a player can distinguish infested from normal blocks by observing that an infested block takes a bit faster to break when using a pickaxe than the stone it appears to be, but without a pickaxe, it still breaks faster.

A silverfish does not spawn if the block is destroyed by the ender dragon.

In Java Edition, using the debug screen, a player can identify whether or not a block is infested.
