Karmic Dice is for the weak!!
Sounds like it might be the opposite!
Definitely agree that the impact of the setting should be clearly explained and it should be off by default.
Also, if the OP is right that it makes enemies do more damage that doesn’t sound like intended behaviour. I’ve never played around with the feature but assumed it made no difference
on average to the attack and damage rolls, only reduced the chance of a run of low or high results.
