Mob drop added via CT. With the ability to add a chance of %100 drop or less!

Here's what I'm thinking I'll try to implement:
import mods.rockycore.Mob

• Mob.addDrop(entity, itemstack, chance);
• Mob.addDrop(entity, itemstack (min), max);
• Mob.removeDrop(entity, itemstack);
• Mob.clearDrops(entity);
• Support for Entity Types ie. monster, animal, aquatic, ambient, & boss
• Support for all entities ie. "*"

Great

This will be PR'd to CraftTweaker instead of added to RockyCore.
