Sneaking through DKS is a good option but you must be prepared because sometimes you can not sneak through them. I did the main floor exploration on sneak mode but then I got tired by this and decided to slaughter them once and for all. It was not that hard if you put your DK to take all the damage. Suply him with health portions and my hero who is a Mage with mana portions. It took a while but in the end all DKs died <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" />
