Basically, if monster spawning is enabled, Every type of monster can spawn. I personally only want to enable spiders and skeletons to spawn, due to Bones and String, and do not wish to have a kit for it. And, If i DO enable mobs, my server starts to lag a bit (1-2 seconds delay), So if theres any way to, Could i possibly get a mod to only let monster spawn on surface/Select what mobs/both
