Sculk Vein

Sculk veins are almost always found near sculk catalysts. These sculk blocks can be found in the deep dark biomes and in any of the generated structures that can spawn there.

You can also generate more sculk-type blocks from getting a mob to die on a sculk block near a sculk catalyst.

In order to obtain sculk veins you will need to use a Silk Touch enchanted tool to get them to drop. You can use any type of tool you want as long as it is enchanted with Silk Touch, but a hoe will be the fastest tool to break them.

If you want them in large quantities, it is best to use a Silk Touch enchanted hoe.

Sculk veins are primarily decorative, but they can be obtained in infinite supply once you find a sculk catalyst. Killing a mob that drops experience near a sculk catalyst will make nearby blocks turn into sculk-like blocks. This includes sculk veins and sculk blocks.

While they are somewhat bright to look at, they do not provide any actual light values in Minecraft.

Q. Do Sculk Veins spread sculk?

A. The only sculk block that spreads sculk are sculk catalysts. Most sculk blocks that you obtain will not maintain most of its functionality, but sculk veins are mostly decorative. You can break and obtain as many sculk veins as you want without much worry.

Q. Can the Warden spawn out of Sculk Veins?

A. If you are in the deep dark biome and there is a sculk block covered in sculk veins, then technically a warden can spawn from sculk veins. However, the only way to actually summon a warden is to trigger 4 naturally generated sculk shriekers.

Congratulations, you now know just about everything there is to know about sculk veins. The sculk-type blocks you obtain can be difficult to understand because of how unique their functions are. However, sculk veins are purely decorative and are similar to glow lichen in their practical uses.
