I still for the love of god cannot win the fight against the spider matriarch and her two accompaning phase spiders. This game, of course, leaves a lot to luck since everything is based on dice rolls, but still... Care to share your superior game combat knowledge?
My party did it at level 3.
I hide my party behind a rock, spider matriarch jumped to them. Few magic missiles, fire bolts, sword smashes and she was dead.
edit: In tactic based combat games it's important that sometimes it's not you who have to go to the enemy. It's enemy that must come to you and be killed on your terms
