Twin Diablo/Dark Knight/Pegasus Knight/Warg Rider spam and/or Ice Blaster II. All of the above work, and so does a combination of them. Spamming Ice Blaster II does seem faster though. There are probably many more similar ways I guess. Note that the boss' attack can't hit melee range at all. This mission shouldn't give much trouble, unless you have low stats. And unless you count how many times you'll need to do this to get all the Sea God Seals needed.
