New guy here.

Keep it that way, more multiple dice roll checks all the way. This is virtual game with quick save/load option after all, so its kind of a save scum prevention measure. If one really needs to pass all dice rolls and cant accept the judgment of Fortuna you have to pay in time and loading screens. How about making the game register if one is loading constantly and making the rolls harder and harder until they cant be passed any more?

Also why do I have always to succeed in dice roll to get something of value, would it not be fun if failing dice rolls would net a better outcome then passing it? Each time you fail a roll it ends in fighting. Kind of understandable that some people want to go save scum and always pass the rolls.
Please keep in mind what you did with goblin fort, if you dont pass with guards you can still sneak in. I wish for more such options and not the tunnel shooter design where you have absolutely kill everything in your line of sight.
