Please make this available for realms!
Very cool mod, but my world crashes every time I try to enter Nether realm(in overworld game works stable). Without this mod Nether works normally... Does someone know how to fix it? (Ver. 1.19.30)
Nice addon but with some missing contents

Freezing dagger(available with all wood-netherite)
Make the poison dagger available for wood-netherite
Can you add sandworms in the limestone caves to make it more dangerous
Does this work on dedicated bedrock servers?
Don't work on realm
A little buggy like if you use silk touch on limonite ore it drops luminite shards and the block and it silk touch also duplicates glow mycelium. But overall really cool addon
can you add like a desert cave with lizerds that whold drop scales that you can turn into armor and a big trex that could be like a boss pls let me what you think i love this mod
Bro, could you add caves that are spider nests?, that have different types of spider and even the odd scorpion. You could also make a Honey Slime and Honey Zombie?
¿Cuáles son los problemas al jugarlo en la versión 1.19? Y buen Addon, es el mejor que he visto.
For some reason all entities within a chunk or two of a slime or desert dungeon become frozen in place and cant be interacted with.
