Minecraft:Sculk Catalyst

Template:Infobox block A sculk catalyst is a sculk block that "blooms" when a Minecraft:mob or Minecraft:player dies nearby, which may convert nearby blocks to sculk blocks (except for more sculk catalysts).

Obtaining

Breaking

A sculk catalyst can be mined with any tool, but Minecraft:hoes are the quickest. It drops itself only if mined with any tool enchanted with Minecraft:Silk Touch. It drops 5 Minecraft:experience if mined without Silk Touch. Template:Breaking row

Natural generation

Sculk catalysts are generated within the Minecraft:deep dark biome.

Mob loot

A Minecraft:warden drops a single sculk catalyst upon death, unaffected by Minecraft:Looting. This is the only renewable way to obtain sculk catalysts. Template:Drop sources

Usage

Sculk catalyst activating.

Sculk catalyst blooming.

Sculk catalysts convert Minecraft:experience into sculk veins, sculk sensors, and sculk shriekers, and use experience to convert many natural blocks into Minecraft:sculk.

It turns the blocks around the dead Mob into sculk or sculk veins.

Blooming

When a living entity (a mob or player, including Minecraft:ender dragons <ref>Template:Bug The ender dragon's death can trigger a sculk bloom, but it does not produce any sculk charges. The ender dragon still drops experience just like it normally does.</ref><ref>Template:Tweet However, new behavior for ender dragon blooms might be implemented in the future.</ref>, Minecraft:withers, and Minecraft:wardens) dies near a sculk catalyst by any means, it blooms. This sculk bloom turns the mob into sculk charges based off its natural experience drops. Sculk charges grow into new sculk blocks, sensors and shriekers. Sculk blocks are always produced, with up to 1 sculk block per experience point. A sculk charge also has a 9% chance to grow a sculk sensor, and a 1% chance to grow a sculk shrieker.

A bloom occurs for the death of any living entity, and can even consume multiple entities at once. A sculk bloom cannot occur if the entity is not directly above a solid block or if the entity is below the sculk catalyst. A sculk farm can be made using pointed dripstone as long as the sculk catalyst is on the same level as the pointed dripstone.

During a sculk bloom, the catalyst gives off soul Minecraft:particles, and creates a patch of sculk blocks with Minecraft:sculk veins around them. Sculk blooms can replace blocks in the Template:Code Minecraft:tag, including the surface materials of most of the biomes in all the Minecraft:Overworld, Minecraft:the Nether, and Minecraft:the End.

Blooming range

A sculk bloom occurs for the death of any living entity within a Minecraft:Euclidean distance of 8 blocks Template:In or 10 blocks Template:In from a sculk catalyst.

If the entity dies near multiple sculk catalysts, only the nearest sculk catalyst blooms.

Sculk charges

When a living entity (a Minecraft:player or Minecraft:mob), is consumed by a sculk bloom, it won't drop Minecraft:experience, because the sculk bloom event converts the entity's experience into sculk charges. One experience point is worth one sculk charge. These charges are used to convert the block beneath the entity into a Minecraft:sculk block. If the block is already a sculk block, or if there are extra sculk charges, the sculk block absorbs the sculk charges. Up to 1000 charges can be present in one block.

The sculk charge in a block is lost when the block is destroyed or broken.

Sculk growth

Sculk growth is an event where a sculk bloom starts on a non-sculk block. The sculk growth first tries to convert the charged block into a sculk block. The following blocks can be converted:Template:Columns-list

Template:IN, these blocks are marked under the Template:Cd Minecraft:tag.

Sculk growth can grow all of the Minecraft:sculk family blocks excluding more sculk catalysts. If the charged block can't be converted, sculk veins grow on the block instead. If sculk veins can't grow, the sculk charge is removed and nothing happens. Each sculk block costs 1 experience to grow. Charge can also be used to create sensors or shriekers, or can be lost to decay.

When a sculk block is grown, it also tries to grow up to 20 sculk veins on every face of every adjacent block. A sculk vein costs 1 sculk charge when it grows on a block that cannot be converted into sculk.

Sculk growth can't happen on a block that is completely surrounded by blocks unless some of those blocks are sculk veins.

Sculk veins are never placed on the sides of a sculk block and are removed when the block they are attached to is converted to a sculk block.

Discharging

Every other Minecraft:game tick, Minecraft:sculk blocks and veins discharge excess sculk charges. This discharge can cause the sculk charge to spread across a patch of sculk blocks and grow the patch larger.

Every other game tick, when sculk blocks or veins discharge, they transfer all of their sculk charges to a random adjacent block. The adjacent block must be a sculk block, a sculk vein, or one of the blocks that is Template:Cd. If there are no adjacent blocks to discharge to, the sculk charge simply stays where it is and eventually decays.

Each time a sculk block is charged, it discharges again. This causes sculk charges to move like electricity in a daisy chain. Sculk charges from different sculk blocks and veins tend to cluster together if there are enough charges, similar to how water collects in a valley or river. Sculk charges keep moving like this until they run out due to converting blocks, constructing shriekers and sensors, or decaying.

If a sculk charge keeps discharging in the same area without creating new sculk family blocks, it decays.

Every time a sculk block or vein discharges, it has a 9% chance to grow a sculk sensor, and a 1% chance to grow a sculk shrieker.

Minecraft:Sculk sensors and Minecraft:sculk shriekers cannot receive sculk charges and are only produced by them.

Sculk sensors and shriekers cannot grow if there are 2 or more sculk sensors and shriekers within a 9×3×9 box, with the bottom center of the box centered on the sculk bloom's origin (or within Template:Code and Template:Code in relative coordinates).

Sculk shriekers generated by sculk growth won't summon wardens, and they shriek more frequently due to their Template:Cd tag being set to Template:Code.

Blooming without spreading

Even though growing new sculk requires experience, sculk blooms still occur for mobs that can not drop experience on death. This is the intended behavior, and a sculk catalyst even blooms when an armor stand is destroyed<ref>Template:Bug</ref> because the game has armor stands labeled as being living entities.

When a Minecraft:player with no experience dies in range of a sculk catalyst, it still blooms and no sculk grows. If keep inventory is on, the player retains experience after dying. This prevents the sculk bloom from consuming the experience and growing sculk.<ref>Template:Bug</ref>

Light source

Sculk catalysts emit a Minecraft:light level of 6.

Piston interactivity

Sculk catalysts cannot be moved by Minecraft:pistons or Minecraft:sticky pistons.

Block data

A sculk catalyst has a block entity associated with it that holds additional data about the block.

• Template:Nbt Block entity data
  • Template:Nbt inherit/blockentity
  • Template:Nbt: List of sculk charge clusters associated with the sculk catalyst.
    • Template:Nbt: A sculk charge cluster. Each cluster is stored within a single Minecraft:sculk block.
      • Template:Nbt: How many sculk charges are being carried in the cluster.
      • Template:Nbt: List of three integers representing the coordinates of the cluster.
      • Template:Nbt: Template:Cd (Template:Cd) - Not to be confused with Template:Cd. This controls the decay of the cluster. If this is Template:Cd, then the cluster was spread from a sculk block or Minecraft:sculk vein, and this cluster can only spread to sculk, sculk veins, and blocks with the Template:Nbt sculk_replaceable tag set to Template:Cd. If this is Template:Cd, then all the sculk charges disappear when the cluster discharges to a block that is not in the sculk family.
      • Template:Nbt: Delay in Minecraft:game ticks until the cluster begins to discharge (or travel) after being created. Usually starts at 1 game tick when a cluster discharges to a new block.
      • Template:Nbt: If the block to replace is an Minecraft:air or Minecraft:water block, the block is replaced with sculk veins, and the faces where the sculk veins are placed are stored in this list. The sculk veins never grow directly on the faces of a sculk block. The same thing is done to any air or water blocks that are adjacent to blocks that are adjacent to this sculk block, if sculk veins can't grow in the blocks adjacent to this sculk block without growing directly on the faces of sculk blocks.
