I think I put together a good strategy...

Ultimate Strategy= Leveling up Locke with Odin (Lock=Fastest Character in game+Odin puts up speed each level+Ragnarok's speed increase=PWN!) Then having my relics be Genji Glove and Offering (Genji glove's two weapon ability+Offerings 4 attacks each ability+Quick=16 attacks=PWN!)
Locke becomes super fast, and attacks 16 times= Major pwness

How's it sound?
