Not doubting you but every play through I've done so far had at least 6 crypts with Bonemass.

Yeah, it's generally a good bet, no doubt. And I've only had that one playthrough where there were no crypts at his spawn (though I generally don't go to ALL his spawns, so might have happened in a few of the others). I'm just saying that there's not a guarantee of crypts there from personal experience.

Other than that one, I've also had a playthrough where his first spawn area only had two crypts (and one of them had a grand total of 29 Iron Scraps in it, hah).
