The description indicates this is specifically to stop you getting unreasonable streaks of bad luck and if its to exist, that is clearly how it should work. It should absolutely NOT work in reverse. However, I have just spent over an hour and a half trying to saving scum 3 successful checks in a row and it was unbelievably frustrating. I didn't keep count for all but the 3rd check, but I would estimate around 100 attempts in total. This was in a single conversation, so I had to roll 3 consecutive successes without saving.
The checks were as follows:
DC 12 with +2 modifier = 55% chance
DC 7 with +2 modifier = 80% chance
DC 12 with +3 modifier = 60% chance
In total, this works out about a 1 in 4 chance (73.6% chance of failure specifically)
Put aside whatever you feel about save scumming, if you have a 1 in 4 chance and fail around 100 times before finally succeeding, its rather unlikely that you actually had a 1 in 4 chance. The most likely explanation is not that I got extraordinarily unlucky (0.736^100 = 4.87E-14 which is essentially a never event). Its a lot more likely that I actually had a much less than 1 in 4 chance of success.
Most conspicuous, however, was how the failures were distributed. The 1st check was about 50/50, which by the numbers is what you would expect. The 2nd check, which should have been about an 80% chance of success was FAR below this. I would estimate around 30%, which over a non trivial sample size (around 50 attempts) is very significantly low. Again, if true RNG, this is extremely unlikely to be so far off what the numbers would predict.
The final check, a 60% chance, I did count the exact numbers and I failed 21 times in a row. This alone is extremely unlikely (0.4^21 = 0.000022, or about a 1 in 50,000 chance). After unselecting Karmic dice, I succeeded after 3 attempts, which given the actual probabilities involved is totally unremarkable.
This leads me to believe Karmic dice is a two edged sword.
Larian, if this is the case, you NEED to change this. No, excessive fortune is not a problem. Getting screwed over by bad rolls is a really unfun experience in a single player RPG and the basic idea behind Karmic dice, to mitigate against the frustration this can produce, is a good idea. However, making save scumming even moderately unlikely consecutive outcomes all but impossible is far more frustrating than having the odd string of bad rolls. If things go unreasonably badly, I can just reload. If I cannot succeed a MODERATELY unlikely series of checks after ONE HUNDRED ATTEMPTS, that is drastically more annoying than any RNG bullshit I have ever had with Solasta for example.
And yes, I can turn the option off. Many players wont even be aware of this. Further, an option which is meant to mitigate against frustration should not add to frustration in equal measure. Sometimes you need to be a bit lucky. Making this all but impossible, and me not even being aware of how it is happening for a long time (its not like the description explains this to you), is very annoying.
And before anyone responds by saying I was just unlucky, run the numbers for yourself. What I describe above is very unlikely to be just bad luck.
Edit: It occurs to me there is further evidence in support of what I am saying in the form of critical failures and successes. I had 5 critical successes, the first 4 of which were all on the first check, and the 5th on the 3rd check after I turned off karmic dice. I had 7 critical failures, which were distributed over all 3 checks. Firstly this means my estimate of 100 attempts is plausible. 4 critical successes on the 1st check, where I had around 100 attempts, is well within the range you would expect, and 7 failures (100 1st checks, 50 2nd checks and 20 3rd checks) is again within the range of what you would expect for 170 attempts.
Secondly, it gives further weight to karmic dice mitigating against good as well as bad luck. Not rolling a single critical success in 70 non first check attempts is actually rather unlikely, and the fact that a normal number of critical successes occurred on the first check suggests that with consecutive successes, the dice became increasingly weighted against me.
When it gets to the point where a mere two prior successes means even a 60% chance on paper appears all but impossible, A) the effect is far too strong in either direction (the effect size really should not be this powerful) and B) strongly suggests that, as per my OP, it appears to be cutting both ways.
I did also relatively early on roll an inspiration dice on a failure on a 3rd attempt, expecting myself to get it back from the inspiration you gained from the event, but that didn't occur (the inspiration must have been gained before concluding the dialogue) so I then reloaded, but the inspiration roll was successful. I refused to relent after that, largely out of bloody mindedness and because I though well, its only a 1 in 4 chance, surely I cannot continue to be THIS unlucky (in retrospect, I absolutely should have just used the inspiration dice). Granted, its a small sample size, but again, consistent with what I believe to be true about Karmic dice. I was able to succeed immediately after a prior failure, but 3 consecutive successes appeared to have a negligible chance of success.
Additionally, when playing the game more generally, consecutive dialogue checks have not been a notable issue. I believe failed checks that still result in success due to a 2nd roll with advantage still reset the Karmic Dice counter. This sequence of checks was during a camp sequence where all the rolls, though using a dialogue window, were not charisma based checks and so no advantage applied.
