i cant remeber how exactly i did it. its been awhile. but when fighting wiegraf i had ramza as a monk with the two swords ability but no swords equipped so he would punch twice and my ramza was strong enough so that if one of the punches was blocked by wiegraf the 2nd one if succesful would kil him. when he turned into velius i left the arc demons alone pretty much and went straight for velius. had everyone with long ranged attacks set there sights on him and did my best to get ramza to punhc him twice.
