The sun harpies on Avatar island resist all magic I could cast on them. 2 FS, 4 Lightning, and a few fireballs before I gave up. If this is intentional thats fine, but if it is, then the loot should be raised to compensate. Right now they drop about 100 GP and a small bit of food each......roughly the same as 2 skeletons, if not less. 1 sun harpy is far stronger then 2 skeletons when everything is taken into consideration, so even if the godly resist is intentional, the loot is far below balanced IMO.

Pretty sure the loot was dropped already they used to have about 200 gp in each.
