I snet one character up to the barrels and when the orcs appeared, i set them off with a fire spell.
hehehe

my favorite battle was against the treants.... i just made a bunch of summons then cast shroud of flames... watching them burn was fun :D

i went through a lot of summons though....

best other battle would probly be against the 4 iron golems near the black raven monastery.... that was a challenge....

I had to use quite some potions with Xvim in the severed hand
