I understand... Infernal Mages are pretty strong for their level, one time I was killing them for slayer, and browsing the internet/forums while doing so. All of a sudden when I turn back to the RS screen, I somehow got lowered to 8 hp, and boom, it hit an 8 before I could react. It was pretty funny... perhaps a bit careless on my part, but I swear that mage must have taken at least 30-40 hp from me. I was wearing dhide and everything too.
