For some reason I feel I should not write this in the article straight on, dunno why. Maybe someone can paste it there, if it makes sense.
I found a strategy on the Silver Skeletons that works really well for me: With the Dragon Long Sword +1 from 2-2 equipped, lock onto the target as soon as it is in reach and wait until the skeleton is about a roll away from you (might take a try or two to get the moment right) and start a R2-Power Attack. The skeleton will roll straight into your attack without even reaching you. Just to be sure immediately follow up with a Normal Attack that will kill him if he survives your first attack and tries to roll away or do a counter-attack.
That's how I deal with them. Thanks a lot for this awesome Wiki which saved me a hundred times already!
