About Sculk Expansion

From Modrinth

Adds new recipes and other functionality for sculk blocks, items, and the warden.

This datapack/server-side mod expands on gameplay involving sculk and the warden.

Warden

The warden now spreads a modest amount of sculk along the ground wherever it walks. This can sometimes include sculk sensors and even active sculk shriekers. If you're trying to contain a warden or bring one to the surface, be careful!

Additionally, wardens now swim faster in water and can't drown. Note that this does break drowning-based warden farms.

Recovery Compass

The recovery compass has an additional use while holding it: every 2 seconds, it emits soul particles that point in the direction of the nearest mob or player within 32 blocks of you.

Gameplay

  • Sculk veins are now climbable, making ancient cities even more interesting to navigate. Note that due to the way the climbable tag works, walking over a sculk vein that's on the floor will slow down your movement.
  • Sculk blocks, sculk catalysts, and reinforced deepslate now indefinitely burn with soul fire when lit. Looks great for builds!

Recipes

In addition, there are four new recipes:

  • You can craft four sculk veins into one sculk block, or vice versa.
  • You can smoke one sculk block into one sculk vein and some experience, providing a way to extract experience from sculk that can be automated, as opposed to breaking it by hand or with a hoe.
  • You can craft eight sculk blocks and one glass bottle into a bottle o' enchanting, providing a way of stockpiling them that doesn't require villager trading.

You are free to use or modify this datapack as you wish, as long as you credit me and rennen and don't profit off of it.
