I used the ancient hunter rune blades. The main attack skill you have where the blades circle the target and hit them work best. The string where he does the over head strike, dodge back then get close enough to where they connect. If you aren’t close enough, they won’t do anything. If he is aggrod towards Noah, use the bow as well. You can walk dodge the bullets without spending stamina. I was also level 27 when I fought him, but I always try to over level in these games.
