No. Not a mod. I didn't jump like a super hero, and I limited myself so that potions were Actions, I didn't use food, I didn't shove as a bonus, I tried to not use height to my advantage or backstab. I also tried to not use more than one surprise round for each character.
Yeah. Nope. Impossible. I was even full health and such. When she gets ticked in particular, it was like game over. She got like so many devastating attacks. I even used potions of speed and such. When an enemy at that stage in the game can reduce a level 4 character to dead in 1 turn from full health, that's too powerful. My Ranger was full health, she ported on him and killed him dead...knocked down...dead.
