The RNGods can be fickle. Just yesterday I was testing for a new Patch 6 bug that occurs in a conversation with two tiefling children. There's a DC 15 active roll for Sleight of Hand and two very difficult passive Perception rolls. I have no SoH proficiency or Dexterity bonus, but have a +3 to Perception from wisdom. Using Guidance cantrip and with Weighted Dice enabled, out of 34 attempts, I passed the first Perception check only 8 times, the second Perception a dismal 2 times, and the SoH check every. Single. Time. I have come to the conclusion that RNGesus is basically Loki in disguise, screwing with me just for the fun of it.
