I've played this game a ton and have seen some weird streaks at times but nothing to make me feel anything is wrong with the RNG notwithstanding the sense of outrage I feel in the heat of the moment lol. I do not play with weighted dice. The only time I felt seriously aggrieved was the time my party rolled 3 critical misses in 4 die rolls. One other time Laz'el missed 10 attacks in a row but that was patch 7 in the scribe fight which was broken so maybe that affected her?
