Mob Drops Your Way
I would like to have possibility to adjust drops from mobs including items from mods. This mod grants easy usage and is working fine on my singleplayer.
It works somehow like that:
1) You start mcwith this mod
2) A config file is created
3) You rewrite properties in that file
Easy as that
