[OOC: Ok, Zach is 2 boxes into overflow damage so he'll take another box of damage every 4 combat turns, so like Sichr said, he's got 8 CT's to live. Also Zach, I want you to roll an Edge(1) test to see if something broke inside you at all. It won't give you more damage, just see if there's something more permanent.]
@Brick:
Through the cloud of smoke, the thermographic channel of your cyber-eyes picks up Zach's form and the even brighter red which the heat from his blood gives off let's you know that he's hit bad, real bad. You whip around the northern corner of the wall and make your way down the other end of the hallway.
[OOC: At a running speed a troll can only go 12 m/IP, that should put you just about right in front of the door to room 507. If you spend a simple instead of a free you can sprint and each hit on a running test would give you an extra meter. Just fix it on your map and edit into your post.]
@Stryker:
You look down the hall at where the blast was and through a cloud of dust you see shrapnel holes completely checkering the walls of the hallway and Zach's motionless crumpled form is lying in a pool of blood. [OOC: visibility is -2 normal/-1 lowlight/0 thermo/-1 Ultrasound]
[OOC: Ok now it's the 2nd IP but you have your delayed action from the first IP and you get to act first. Remember, you're prone so you need to do that test and spend a simple to get up. Just a strategy note: if you're gonna cast spells, you should probably overcast cuz only 1 box of stun will take you out, so you'd rather have physical damage. Zach's gotta be stabilized first though.]
