Looks like this content is intended for the next tier of the level cap ><. Might be possible with double, though likely triple melded gear, top tier food, and popping mega-potions of (insert your attribute of choice) every 4 min, especially when all the spikes pop. Can't wait for extreme version of Garuda ^^.

P.S. SE put out a contest for guessing the days err months it will take for the 1st win of Ifrit Extreme. Winner get's to bypass Garuda extreme lol.
