I was bored and decided to test this out, and to my surprise, it is really fun to use!
Magic Dragonrider Twinblade (RH1) (Magic twinblade for backup just in case)
Dragonrider Bow (RH2)
Magic Staff of wisdom (LH1)
Drakekeeper's shield/drangleic shield if you want a shield.
Honestly, you can wear what you want, but I wear:
Grave Warden Top
Lion Mage Cuffs
Crystal Magic Weapon
Soul Spear 2X
I recommend that you fit this build to your playstyle, and to mess around and see what works best.
