You are given around 10 elven pikemen and your base character. I don't have any of the spells from my previous quest and my health has suddenly dropped to when I started the first mission. Your only benefit is this acid bomb attack and that doesn't help entirely. You have hordes of rats running towards you constantly if you go forward or you can go off to the right and fight some troll-like creatures. Anyone have any advice for this one?
