I've been trying out sand devils with my level 50 wizard, and boy I can't figure out a good way to kill them efficiently. Any tips? Even when I put Bravery up, their bolt DS is just annoyingly high. E-wave and Tonis Bolt are too unreliable for quick knockdowns, the sandstorms get going fast. I can dispel the sandstorms but by the time I've killed one devil, I am out of mana.
