It's possible but I'm warning you, it is a LOT harder since that pure that Boom Headshot was talking about earlier. They made it so all monsters move diagonal like the bats, instead of side to side until they're directly north/south of you. So watch out, and DEFINATELY don't expect a cape within the first 2-3 tries. Good luck
go to YouTube and search "Killing Jad" then look for the one called "Lvl 40 killing Jad", he has 50 range and 10hp, 43 prayer, and he kills Jad, gets the fire cape. also on there is a guy who kills him with flowers and one guy kills him with a butterfly net <(^^<)
