Thanks all for these interesting analyses!
In conclusion, having Advantage almost perfectly counteracts the effects of Karmic Dice, except you get less crits.
For all other distributions, Karmic Dice seems to raise the average roll by 2, making it less likely that you'll roll numbers below ~9.
I’ve got a bit confused in amongst all the data whether this is the case for our party, enemies or both?
And whatever the answer, I guess the next question is whether this is what it is
supposed to do? Do we actually know for sure?
I think I recall in a PfH Larian said they introduced it partly in the hope that players who reloaded on failed checks might be able to use it to reduce save scumming, and I think someone else mentioned it was partly in response to players complaining they missed too frequently. I guess increasing the average roll for PCs and allies would be one way of addressing that, though not necessarily the best. And I guess extending the same advantage to enemies would be karmic, if that’s what is happening!
