Try going to Pyramids basement level 2 and using Turn Undead against Ancient Mummies. Keep Safety Wall up and it should be relatively smooth. Turn Undead success rate formula is based off of your Turn Undead skill level, Int, and Luk (as well as off the HP stats of the monster), so try to max out your TU level, as well as a moderate amount of Int and Luk. If you keep Safety Wall up, having lower HP/vit shouldn't affect you too much. Watch out for Arclouse, though. If you run into one it may just be better to Teleport away.
Another alternative would be to Heal bomb monsters in Glast Heim Churchyard, or even use Magnus Exorcismus. ME builds usually consist of high Dex and Int. Heal bombing builds are usually just max/high Int and Vit/Agi.
And the other alternative would be to go to Skellington and use Magnus Exorcismus on the mobs there.
