The gears can be seen turning, response forming, almost, almost getting said before  something dangerous and magical interrupts the troll. The first event only registers to Alex in the horrible wounds and flesh disintegration on the Chillers; the spell does nothing to her machine body or mind. The second one registers as ignorable force. Focused right, it could have done damage. But spread and done magically, it just shook her and felt  a bit overbearing.<br/><br/>For better and worse, it doesn't actually kill anyone. Just leaves a bunch of angry gangers with an obvious target. The room nearly shakes from the combined cries of "frag the ork!"
