I noticed something while playing MotB that can be used to calm down the spirit eater system to save you from an out of control feeding frenzy or allow you to have a feeding frenzy and then chill out completely while looking all innocent as if it never happened…
When you rest you reset your spirit eating abilities but you lose spirit eater points so get more hungry.
When you travel on the world map you don’t lose spirit eater points but your spirit eating abilities reset.
There’s a spirit deer outside Mulsantir it can become your new best friend in times of need. Leave Mulsantir use supress on it, go to the world map transition just up the path, go back to Mulsantir, spirit abilities now reset, leave town again, suppress on the deer… Carry on for as long as you want.
