This pack adds the Sculk from 1.19 early but rats the nether so i also added the Nether Reactor

- Sculk Catalyst
Spreads sculk when fed experience, acts as the center of the Deep Dark biomes
- Sculk Block
When broken, frees experience trapped in the sculk
- Sculk Sensor
Detects Vibrations and now activates when sneaked on top on
- Sculk Shrieker
Shrieks and applies Darkness whenever fed a signal from a sensor or stood on top on, can spawn Wardens if on top of sculk and is silent when waterlogged
- Nether Reactor Core
If built right, and if fed a reactor block (Netherrack, Basalt, Soul Sand, or Chiseled Blackstone), will cause a reaction depending on the block that was placed in it
Netherrack can be gathered from Ruined Portals to start reactions
- Glowing Obsidian
Unbreakable block spawned by Nether Reactors

Also the warden can teleport, has a projectile, and deals 30 damage with 500 hp, you're welcome : )
