Love having all my party members twiddling their thumbs defending and healing while one guy fails his steal rolls 10 times in a row
I extra love it if the steal move deals damage so you have to also worry about the target dying from too many failed attempts
I double extra love it when it’s a boss battle when on top of everything else the story momentum just grinds to a halt while you fuck with a stupid RNG for 5 minutes
I would argue that grind for full completion is not even mechanics, it just fake content using the normal mechanics and maybe force you to minmax and run around really much.
