I turned off loaded dice, because I don't want an unfair/distorted gaming experience - que sera, sera, and all that. But nobody told the kuo-toa. Their rolls in my fight against them:

11, 17, 16, 19, 4, 7, 13, 14, 12, 19, 10, 14, 9, 14, 17, 16, 2, 19, 6, 4, 9, 17, 17, 7, 8, 18, 13, 16, 20, 19, 18, 16


That's an average roll of THIRTEEN POINT TWO.

My party all had AC 19 (or 17 if I forgot to equip a shield at end of turn). That meant the fishy tossers had to roll at least a 14 (or 13) to hit. Which you would expect them to do 30% of the time. NOT 60% OF THE TIME.

Yes, we survived, but both Wyll and Shadowheart were dead dead dead (for comparison, Shadowheart's saving throw vs Ironbound Pursuit: 5).
