A few years ago, I was experimenting with creating mods using MCreator.
This is the best mod I made with MCreator. It's mostly finished aside from a messed up texture on an item and me forgetting that monster spawners don't work without light.
You should use a mod that makes spawners activate with light or break into the boss structures from above to prevent it from putting you in adventure mode so you can break the lights.
The riot boss doesn't require the item the signs say, I messed that part up.
I highly recommend using a mod like Just Enough Items.
The mod features a dimension, two armor sets, two multitools, melee and ranged weapons.
There's 5 bosses, 2 are in summoned structures and the other 3 are summoned.
You need to make meteorite blocks and a klyntaar portal igniter to go the klyntaar dimension. Just like a nether portal.
There are 3 basic enemies in the dimension, one is only in a boss structure.
