About this project
What does Sculk Expansion add?
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
climbabletag 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.
