About this project
What does Simple Sculck Backport add?
Hello everyone. Have you ever wanted to have the Catalyst and Sculck Block in your 1.12.2 world? Well, now you can!
This mod is made with MCreator, so don't expect anything super professional.
This mod does NOT include the Sculck Sensor, neither the veins, neither the Shrieker.
This backport does not work the same as in vanilla 1.19+.
For this catalyst to work, the monster MUST die right on top of the catalyst.
This catalyst will convert blocks in a pseudo-circular shape centrered in the catalyst that are one layer below it. A circle of around 2 blocks in radius.

A super idea i can give you, is to build a cobble generator with lava and water to feed a 3-wide (maybe even 5-wide) platform of blocks centered below the catalyst. If there are moster dying, i will convert the blocks into sculk.
I recommend to kill the mosters with fall damage and make they land just on the catalyst, but you can decide how to kill the monsters.

If the sculck blocks are broken without Silk Touch, it will drop experience, if broken with Silk Touch, it will drop the item.
The catalyst block spawns in low abundance in only four specific biomes, at low Y levels:
- Extreme Hills M
- Jungle M
- Roofed Forest M
- Savanna M
I hope you find this mod useful.
You CAN use it in your packs. Just, please credit me.
