Yeah I'll try the great jaggi armor and sword. I tried heavier weapons that had 300 damage but I completely sucked with them as I thought I had an opening but by the time the weapon had finished its long animation the boss hit me. I just can't focus on trying to hit him and trying to compensate for those types of weapons large delays at the same time.
I've tried to beat him 3 times today for a total of like 4 hours so I'm getting frustrated and am not having fun, I'll take a break and try using that armor and stuff tomorrow
Yeah I've tried doing that a few times but I usually get thrown off even when I hold L when they try to shake me off.
The Great Jaggi or Seltas sword will be a good boost in both raw damage and sharpness. Take the time to use whetstones and bump that sharpness back up when it starts to dull. Dual Blades is quick like sword and shield but offers a few tricks for boosting damage as well. I think though with the great jaggi sword and eating a meal for attack boost you should have enough to put him down. Good luck!
Also, if you are interested in online play, when I started playing MH I grouped with some GAF members and just watching them kill stuff helped me out a lot, I'm sure plenty of people here (myself included) would be happy to do some low rank quests with you.
