Now, I am using the command in my BiomeGenBase:

 

this.spawnableMonsterList.clear();

this.spawnableMonsterList.add(new BiomeGenBase.SpawnListEntry(EntityZombie.class, 100, 4, 4));

 

(side question, I know those last 3 ints are a way to determine how often they spawn but I can't find documentation on it. So which does what?)

 

Would I have to make another Entity class extending EntityZombie class and override the methods to do with Armor and weapon generation?

Is there any methods that lets me check if an entity is wearing armor?
