dont bother using many fancy abilities, just stick with crash. you wont have to use anything fancy until you have to personalize the abilities to fit the bosses in the vortex
They're pretty easy. I use a gunslinger, guardian, and destroyer. Since the gunslinger is the weakest, I put intervention on her. Then I use wound on one enemy and then smash on them on the next turn. Usually doing this a couple of times easily gets rid of one of the illusions. Once you get rid of one the other two are easier to get rid of. Just use support abilities and be use the right abilities together. (like smash and wound)
