Watch out for these guys they hit hard and fast. Im pretty sure they are resistant to most types of newbies.
Anyway here is what you should do...
As an iksar necro I always have minor shielding and lifetap memmed. What you should do is make sure you are fully buffed first (minor shielding), then pull the skel with your lifetap spell.
Then .. now this is the hardest part ...
Just stand there while it hits you as you have yet to figure out where the auto attack key is !!!
You have been slain by a decaying skeleton.
Returning to your home point.
