OT Hammer quest Question

[DBStrong]

As a L49 Necro (Dark Elf of Innorruuk) with the L49 undead charm spell Cajole Undead, can I just walk up to Foreman, charm him, hand in Jade, and get the hammer?
My faction is essentially baseline. Haven't killed anything in KC for the negative, but not done anything to raise it either.
My hesitancy is due to older posts regarding him being very resistant, even to higher level ENC's with max CHA.
Am I being overly cautious? or fearful for no reason-- Should I just go get the damn hammer already...?

Thanks for all legitimate input. I do appreciate it.
