I thought the Worg was insane but then I ran into this guy with my party at level 4.
Power Attack, Lethal Stance, Rage (with bonus to will saves), and on top of that he even had the iron will feat too. Performs three attacks and had a bonus to attack of +21 with a +2 greatclub and did enough damage on a regular hit to whipe out to two thirds of Valerie's health. 32ac with blur was not going to cut it, he was guaranteed to kill everyone.
Clearly this was a point where I probably should have retreated and waited until I reached level 5. But I was determined to do everything in as few rests as possible and kill the Stag Lord before 30 days. So the only option was to pray that Linzi's Hideous Laughter hit and try to kill him before he woke up and killed everyone. Developers anticipated people would try this and gave him iron will on top of rage for will bonus saves. Proceeded to reload a ton, which wouldn't have been so bad if the lights in this cave weren't bugged for me and made loading times really long for some reason.
Still can't believe I did it. Almost gave up. Had to use every last ability and spell I had. But it was worth it for that Amulet of Natural Armor bonus +2.
This game is the best.
