i used proslyte armour and i didnt have any truble doing this quest (except for the agility part). You might get hit often once or twice, but that will be about it. You can often run in a corner and relax a bit. Also it isnt hard to kill those shades (low hp, low def) if you need some peace. Do this quest in world with very few ppl in it, because it will make shades respawn slower. bring emergency tele, 5 prayer pots, the rest of inv monks and you will be just fine
