I would like to see integrations added for the mod mentioned in the title.
I confirm it is available for the latest Minecraft version at the time of writing.

About the mod

Link to the mod page (e.g. on CurseForge): https://www.curseforge.com/minecraft/mc-mods/caged-mobs

Link to mod source/API:

https://github.com/Corgam/CagedMobs

What should be integrated exactly

It would be nice if you could farm vampires and hunters in the cages like having corrupted soil or a blood tree (+15% modifier) as a block in the cage
The barons should need a netherite DNA needle in order to collect ones DNA and be able to farm their pure blood, but give it less chance to get a pure blood purity 5

I can help with

The creator of Caged mobs made it so you can use Crafttweakers and has a tutorial on its github page

Additional comments

I tried to use crafttweaker myself but my head exploded beacuse I could'nt understand how it works
