No, it doesn't. You'll have no trouble with Wiegraf if you apply these two abilities: Yell and auto-potion. Clear everything but X-Potions from your inventory, and with Auto-Potion active Ramza'll heal himself pretty solidly after every attack. When the battles starts, yell yourself up to a good number of consecutive turns - six or seven, perhaps. It'll take a while, and you'll have to break off from this every so often to use extra potions; Wiegraf can do some serious damage. Once you have a solid turn buildup, knock Wiegraf down. He'll transform, but - this is where yell does its work - you'll have about seven turns to the enemies' one. Keep the other monsters (what are they, Ultima Demons?) busy with your own troops, but Velius should fall to Ramza alone in a mere few turn cycles.

i can't remember what class i'd put Ramza in for this battle, but my guess would be Squire - for the 'yell' ability. Once i realized that Ramza's 'squire' class is actually more powerful than the generic version, i kept him there for the rest of the game.

If you aren't stacked on X-Potions - or don't have auto-potion - i'm not really sure what to tell you. If none of the other recommendations in this thread work, it looks like you're in for a restart. This is a pretty common restart point in the game, as more often than not people will overwrite their worldmap save and then get stuck on this very battle. So... i guess you can take a bit of solace in the fact that you're hardly the first one with this problem, i suppose.
