Ya the same problem occurs in tutorial. Before we open account creations that place needs fixing. It took me over half an hour just to make it to the end of the tutorial to start playing. There are at least 70+ rats at the end and because there are so many, they wont let you move through them because one is too weak.
Although I agree with Falin. 2 earthquake spells and you have a decent amount of loot. Maybe 3 to finish off the Liches too
