Okay so this is mostly for my own benefit since I’ve known the old feed powers so long that I have to have some reference to help me learn what the new changes in X.33.1.0 are so I can see them all in one place.
FP value changes are from what was announced in: Exalt, Oryx 3, and Feed Power [Update preview]
I’ve grouped them by dungeon/location to make it easy to tell if a dungeon has had a relative buff or nerf in this change to the FP on its items.
Happy farming.
