So from what I've found searching around, this is what is known as far as the effects of the various AF pieces go on skills. There are some that are unknown though: namely Enhanced Elusive Jump from the Drachen Greaves and Enhanced Excrutiate from the Wizard's Coat.
Has anyone figured out what the effects are for those?
