Here is my theory on the crux of Crota and remember this is [u][b]purely speculation.[/b][/u]
my theory is based on the name Crux of crota and the eris item Embalming orb and this may be a long shot but looking at the definition of both Crux and embalm leads me to believe that the embalming orb will preserve the [u]Heart/essence/core[/u] of crota so maybe if you have an embalming orb in your inventory when you beat him it will become the Crux of Crota . please comment and i will test this tonight.

NO. You need eidolon ally with the Burgeoning Hunger upgrade UNLOCKED, but not purchased and you need to beat crota on hard MORE THAN ONCE with eidolon ally equipped. Just theorizing, though
