First off, make sure you have the power bracelet from fire island.
Use your mirror shield to shine light on the boss, and then pick him up (that's what you need the bracelet for) and throw him at the spikes on the wall. He'll turn into a bunch of smaller poes. Kill the smaller poes (the hurricane spin works wonders here) and then you'll win the fight. If you dont kill all the poes at first, just repeat the earlier steps.
