I just created an awesome nether base, and then realized that as soon as I spawn in on survival a ghast will most likely destroy most if not all my work. I've done some looking around and can't seem to find what I'm looking for.
Does anyone know of a mod with the capabilities to change mob spawning preferences based on chunks or something? I don't want ghasts to spawn in my nether base, but I don't want to completely turn off ghast spawns.
Help would be more than wonderful... it would be delicious.
