If you think Demonbrandt is powerful, just wait until you make Northern Regalia, it has an astounding 540 damage, from which 270 are magical xD It kicks everyone's ass in that game, when you're either PW or PB CT :P
Moonlightstones are easy to farm, in case you're needing chunks or pures, just log in at the Old Monk Archstone and farm off the CG that's right beside it, make sure you equip Thief's ring and go quickly for the kill, since there's also the BP Guardian there.
