Those should be good enough but you should wear prayer efficient gear, verac's helm for your helmet and whatever you choose for the rest.

Ive seen it be done on accounts with 50-60 range, and no combat or def.
They were under 40 combat and had firecape. You'll do fine
Just do your research, look on youtube and google and what not
for quides/videos/stratagies and you should be good

Ok, thanks to both of you^^

Sure they should be good enough just as a recommendation. If you have i think it is 55 slayer, but broad tipped bolts and a rune cross bow and invest in a zamorak unholy book also put about 200 emerald bolts (e) in your inventory and when you get to wave 63 for jad equip the emerald ones as they can poison and do a lot more damage. Just be sure to turn up your sound effects for the fight so you can hear if he is attacking you from far away which one he uses. Jad isnt about skill very much so its more about prayer switches. Miss one and you are dead basically. f1 for inventory and f3 for prayer book try and use these as it will be a major advantage when having to brew and then prayer switch. And finally, if you manage to trap jad on wave 63 where he cannot attack you, stay by your computer and take a few deep breaths but dont take longer than 10 minutes because you will lose your progress in the caves. Good Luck and keep calm when you get there
