The only things I gotta say are: 

1: Mind reading is a no go, at least this early in the game. Second arc would be alright, first arc however, no.
2: Make it so she has to be near the person to do the illusory world. Within arm's reach. This will increase the risk required to use it.

Also, I like the Chasers idea. I'll have to add in a list of the varying machine soldiers.
