It would be really great if we could have a config file that has an option the blacklist mobs from being possessed (say if one of them cause issues/crashes ).

Also some other ideas would be an option to adjust in the config the amount of time it takes to level up a mob.
Maybe have it so you can go in and specify abilities for mobs (I know this one would be hard to implement, most likely just wishfully thinking here)

Option for boss possessions?

I'd love to have an option to turn off the timer limit as well, if possible?
