The description leaves many things unclear and raises many questions.

Unlike the creations of standard necromancers, a gravewalker's creations remain forever tied to her will...
Bonethrall says "take control" which is very strong wording. Later it says her "minions" implying that this refers to creatures she has bonethralled. But command undead doesn't give control over intelligent undead; merely makes them friendly. And yet, the same paragraph implies it does.

(once control is established, the undead remain controlled even if outside the witch's aura). Intelligent undead receive a new saving throw each day to resist her command.
This raises questions about possess undead.
Quote:
Possess Undead (Sp): A gravewalker may take direct control of one of her undead minions within her aura of desecration, as if using magic jar;
How much like magic jar? By a strict reading, magic jar won't work on mindless undead because they're soulless. If bonethrall is what makes an intelligent undead her minion then does casting control undead on one also make it a minion for the purposes of this spell?
I get the feeling that the writers intended for bonethrall to behave more like a long-lasting control undead; not command undead and that you can only possess those you've bonethralled. But that's only strongly implied. Per the wording, that's not the case.
This debate just keeps raising more and more questions over on another RPG forum so I'm hoping we can get an official clarification of how the Gravewalker's undead-controlling powers are supposed to work with regard to these various questions.
