This is a server-side mod(you can also use it if you have a modded client on a single-player world). I wasn't able to put the picture in because I had to many but if you put 4 emerald blocks into the corners of a crafting table, a netherite ingot on the top center an apple in the middle and fill the rest with nether stars you get something, I'm not going to say what though, also it gives you four because of the expensive recipe.

below is the crafting recipe for what I described above incase you could not understand what went where

ENE
SAS
ESE

E = emerald block
N = netherite ingot
A = apple
S = nether star
