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
Admittedly while I dislike all the steal mechanics you described (especially FOMO and having no damage/target dying) I really like the concept of stealing in games
It seems like the logical conclusion is to have no one-of-a-kind items be steal-based, just money and replaceable items, and bosses (short of the final boss) can give you early access to what will later be a normal resource or something like that.
