I finished the game pretty soon after release… I don’t even know what was a bug anymore. I’m 100% sure you can’t be that over powered in D&D due to item atunement limits for one thing – feature or bug…
My cleric was 147 HP, 26 AC, +2 HP/rd, +3 HP/rd, and multiple attributes over 20 with resistance to most elements. Drow or dragon?
