Yeah, just level up to 40, get some decent gear and set your gambits accordingly (pretty much standard, but a handkerchief to cure oil status is recommended). Kill all the little bombs, but leave one, otherwise he just starts spawning them heaps.

You'll find his HP drops fairly quickly with a party of level 40. Though he always seems to do Renew, which is a pain. So instead of just getting his HP low over and over again, hit him with a quickening chain.
