Dayum the pro foxy players beat me too it.
But yeah, you only really need LK for Mines and Mages.
I don't tend to comp my equip with LK (Only if I have doubles)
Just get a high LK Base and comp it with DA Then really you won't need a pure LK set because most Light Mages these days don't have LK since they concentrate on MA for SoH.
