Its kinda simpel.. Find one of them stone enemies(The once that can make a shield) or the guys that have stones surrounding them.
And use 3 diffrent powers. I used smoke, neon and the TV power.
Just hit the enemy with one or 2 shots of every power and when he dies the trophy pops..
I made a little video how to..
I use Video,Smoke and neon..
I allready have the trophy so it didnt show up .
