Blocking isn't all that brilliant. Dodge is incredible on the lower bloodlines (I beat him on the 3rd with dodging), and parrying is something you should get the hang of for when the end boss is a higher level.Yes, it is possible, and not as difficult as some make out. Just keep upping block and health, and get a really good weapon early on. I think it is probably possible to beat him on the 3rd or 4th bloodline. I did it for the first time on the 7th.
Another probably easier tactic would be to build up magic and use heal during the boss battle. Make sure you practice blocking and especially parry.

Health is important for obvious reasons, followed by (IMHO!) magic so you can heal frequently.
