Knights of Tezoth

Believe me, with Halmeldir, I've had a hundred chances to regret my help. Moreover, the most important thing is that Arets barely even played. One-Eye dragged that lever-guarding body behind him on a string, like a chained dog.

There was also Arita, the dragon-woman. Not exactly OP, but her failure in the main quest was incredibly stupid. Simply put, she was almost the only combat unit who got taken out by random losers due to bad rolls.

There were overbuffed undead with giga-crits, whom I heavily underestimated.
