This mod adds Fate to the game which is an invisible number attached to each player which comes up randomly in the world or when somone drinks a Fate Potion, Fate goes up or down slightly depending on what you do (such as finding certain items killing, certain mobs ect.). Having a High fate tends to have good things happen (such as giving positive potion effects and valuble items) where as having a low fate often makes bad things happen (such as giving negative potion effects and spawning hostile mobs).
You can use this mod in your modpack.
