Don't triple post, though I know why you double posted.
You should do just fine. What exactly is giving you problems? He only hits for around ~100 damage in that battle, and that was with a level 3 Galuf.
Granted , he had all the best equipment on, Bare, in the back row, with the Doom Axe, to survive, but still.
Edit: Or maybe it was the front row. But yeah, if you still can't beat him, just train a bit, though he really isn't that hard. (His other forms can be a pain though...)
