A '''sculk catalyst''' is a block that converts blocks around it to blocks in the [[sculk family]] (except for more sculk catalysts) when a [[mob]] that drops [[experience]] dies nearby.

== Obtaining ==
=== Natural generation ===
Sculk catalysts are generated within the [[deep dark]] biome.

=== Chest loot ===

{{LootChestItem|sculk-catalyst}}

=== Mob loot ===
A [[warden]] drops a single sculk catalyst upon death, unaffected by [[Looting]].

=== Breaking ===
Sculk catalysts can be mined with any tool, but [[hoe]]s are the quickest. It drops 5 [[experience]] if mined without [[Silk Touch]].

== Usage ==
[[File:Sculk Catalyst Bloom BE1.gif|thumb|upright|Sculk catalyst blooming.|alt=Sculk catalyst blooming.]]
[[File:Sculk Catalyst bloom and spread sculks.gif|thumb|upright|It turns the blocks around the dead Mob into Sculk or Sculk Vein.]]
If a mob dies near a sculk catalyst, it can cause a sculk bloom. The catalyst's texture will react, causing a blooming animation. The sculk bloom produces [[sculk]] blocks, [[Sculk Vein|sculk veins]], and [[Sculk Shrieker|sculk shriekers]]. These blocks can be used as decoration or harvested for experience. The sculk bloom also produces [[Sculk Sensor|sculk sensors]], which are useful in redstone contraptions.

For more information, see [[Sculk Growth]].

=== Light source ===
Sculk catalysts emit a [[light level]] of 6.
