You should be able to kill those skelletons. If you have meteor strike use it heavily and drink mana potions if you have enough of them all the time.
A good way to do this is to use spacebar to pause the game because when paused you are still able to switch weapons, spells and drink potions or use the heal spell.
This should help, if not run as the others said... <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />
