~lvl62 dungeon and people, the bonecrusher is seriously overrated That is true, I did some very rough math in my head. You receive roughly 400k prayer exp if you max out melee with armour zombies. However, a small bonus is a bonus. I was thinking in terms of slayer, certainly by the time you're using kuradel there are very few tasks that actually drop bones, so the best usage is indeed AZ/bandits, but even then it's very small as you said.
