I'm not sure why you'd compound anything for LK for a strictly pvm Soul Master. In my opinion, compound all MA besides for your shield, which should probably be HP. If you need HP, supplement as need be, but really, a decent shield should do you fine.
edit: just reread the OP and saw you have a 4 in charm? I can't tell if it's 1441 or 1414, but if you're 1414, I see even less reason to compound anything but MA onto anything. Having a decent shield with a 1414 build should do you perfectly in pvm situations.
