So i've been reading about an option called
Karmic Dice, and i think i should give a heads up on it here.
The option is under user settings, and what it does basically is create a "loaded dice" that decreases the chances of failing rolls too often. It was made with the intention of avoiding situations where you just keep failing over and over in a row which might feel frustrating for some players.
And indeed, in most situations, it'll help you, especially during dialogue. I imagine it must advantegeous to leave this on if you're a new player that doesn't fully know what he's doing.
However this option also works for enemy throws and combat. It can create unfair or unbalanced situations for specific builds, so if you
do know what you're doing, or you just want the game to play more like it normally would,
make sure to turn this off as its enabled by default.
Keep in mind this is all based on EA version. Not sure if there'll be any changes in the final game.
