Maker question for forging my staff.

Hi guys, I'm going to be collecting my items now for making my Reverse Aeas Hand staff (yes, I'm spur of the moment) and I'd like to know what jewels to use on it. I'm trying to get my Advanced Sapphire and Advanced Wisdom crystal already, cause that adds 8 magic attack, but I'm not sure what jewel to use last. Or should I just use those 2 jewels. I don't really know. Any advice would be appreciated.
