So, I'm pretty sure now the dice rolls are messed up.
Not talking about skill checks, but damage or heal dice.
One one hand I'm quite sure Larian did the easy way of 2d4 being a random number from 2 to 8 instead of actually rolling 2d4 where 5 should be the most common result and 2 and 8 should be rare results. As it is statistically nearly impossible how often you get a 2 on 2d4 or 4-5 on 4d4, etc..
Second I've noticed several times, that the results are not even logically possible. 4d4+4 should not allow 7 as a result or 2d6+3 a 4 which already happend to me.
That's not complicated to program guys...
