Alright, I just can't seem to beat this guy, he heals the riot police guys all the time and shields them too, then he even has his forcefield which makes him invulnerable basically. How in the world do I beat these guys? I'm using a physical based bio class btw.
Kill the other opponent first, then start taking the guard down with some heavy envenoming, while Veradux keeps healing you and the other guy is in an offensive state. As soon as the shield drops, try to prevent him from making that move again, using break or something along those lines.
He always recasts the shield with 1 turn left on the previous one. If you break the shield before he recasts it, the new shield won't do anything. So, basically, bash him till the shield breaks and you're good.
Since I'm a psycho (I mean the class not I'm mentally insane) I can do lots of damage. Most of the time I just crash their shield. Or if you're a hydro you can try to stun them before the shield runs out so they don't put it back on then have everyone on your team use a full force attack.
And don't be intimidated by the "40x" and "20x" strength in the description. Their strength isn't as high as you probably think it is. Their shield can be easily broken.
I did this for my legend run with a level 19 psychotic. I respeced my guy for full shock coma, full salvation so veradux could heal 2000 hp a turn, and then full damage (shock therapy, electrical storm, wraith form, charged blood). The strategy's pretty simple- keep veradux on salvation & healing and concentrate on the enemies one at a time.
At the start, keep one riot police in a coma at all times and concentrate on the other riot police; the android guard doesn't do too much damage. The first riot police should die within 2-3 wraith form rounds. I was a little careless; at this point Roald died.
Next, keep the android guard under coma and pound on the next riot police; should die pretty quick as well. Then do this for the android guard. Don't be upset if you can't break through the android guard's shield at the end; just keep pounding on him. Eventually, he'll run out of focus and stun himself to recuperate his focus; this is where you can do the damage to him. 1-2 wraith form rounds and he's done.
