There is a way in where you can get away with fighting just a few of the skellies. It does mean having to jump a bit. Rather than try the front door if you go up the hill to the side entrance you will find a closed gate entrance. You will have a small group of skellies at the entrance but with some cunning you can lure individuals away and pick them off like that. Next at the gate look to your right and you will see a small ledge with an opening above it. Jump onto it and then up into the tower. Get ready for a frantic fight though as a larger group of skellies will be onto you straight away. Once you have taken care of them then you can then jump up to some overhead platforms. On one of them will be a lever which will open the next gate. Go through, up and out to the left avoiding any skellies up ahead. Then climb up a long ladder as far as it goes. From there you should be able to figure out the rest. There are skellies outside the door to the Lovis chamber but you can outrun them and go straight in. Personally I prefered taking the time to kill the skeletons as it helped raise my level. If you have ranger skills there are various vantage points you can use to pick off the melees. Good luck.
