First of all you can easily kill yourself with it without warning. Crushing 50 dullite rocks takes something like 160 energy and there's no indication beforehand. Secondly, if you then get back from the being dead, you can _still crush 50 rocks_, even if you only have 20 energy, which the _doesn't kill you_. So currently you can just get a lot of rock beforehand, a couple of crushers, and crush them all by dying just once. That doesn't seem right.
