Not sure about you but that was easy for me I always had a godly setup. Get to a safe zone summon all your creatures with a priest or druid mage ect need three of them. Cast really strong creatures summon some weaker ones mid level then, then summon higher level creatures until you run out of summoned creature spells then sleep then summon all you high level creatures again send them in then you go with them and by that time all the monsters are easy to kill. When I played the game the first time in BG1 Bg2 NW1 NW2 ect I tanked all those games and beat it then after that I liked massing a army per say with creature spells and sending them in as if I was the general and spilling monster blood and dropping them all to the ground. Only time my tactics failed was sadly on the guy you bring all the bones to bring him back to life and fight him till I figured out a good way of defeating him. Personally I like a game to take super long and puzzles don't mind them taking a while I like a good puzzle unless they make no since of course. I hope this game comes out sooner then the later though I think they should focus and getting what they had planned out now first then everything they do after that goes into a true expanstion not a dlc most dlc are super short 10 to 15 hours is not even a true dlc a true dlc is like 30 hour plu.
