If you don't plan to get 99 dungeoneering, and you're just playing for the rewards, dungeon tokens should be valued at about 2k per 1 hour. Bone crusher = 17 hours 17 hours could be: 715k prayer xp @ 1m income 1.3m prayer xp @ 2m income 2.5m prayer xp @ 5m income 1m prayer xp = 500 hours while training with bonecrusher. That means for the bonecrusher to be better, you'd need to train for the following amounts of time: 357 hours (approx. 50m melee xp) @ 1m income 650 hours (approx. 91m melee xp) @ 2m income 1,250 hours (approx. 175m melee xp) @ 5m income So unless you're planning on training melees for a very long time, bonecrusher is not worth dungeoneering for. However if you're going for 99/120 dungeoneering and have the tokens, you may as well. But there are many better uses of tokens before you buy a bonecrusher.
