It's MOTW, so get it now. Recommend running 28-35, so you get Navi Fairy and Griffons
Party: 1 TB Monk, 2 Summoners with Guardian pets (monk/huntress), 1 ranged DPS (look for weakspots and fill them in) (or some other support, like EV pet on summoner)
Hint 5: Keep an eye on this, occassionally a wyvern will slow creep up here and cap that crystal, just run your DPS over if needed, but for real keep an eye on it.
