Wait until the stun has past, go in and then drag it back to the middle.-correct answer is to wait until the stun has past and then go in and grab it. every vistrix fight there is an off tank in the tank tunnel watching everything that goes on. if there so happens to be a terror or horror that gets on the tanks let the off tank in the tunnel use a range attack and pull it away. you should never run in and grab the terror or horror when the stun is coming, because you could get stunned yourself and die. wait till the stun has passed and then go into the tank tunnel and help drag the terror or horror back to the middle or help kill it.
