This isn't really related to the current vote, but I have an image of Mirande standing far down the tunnel towards their next target, out of eyesight, but not the range of her rifle. With precognition, invigoration, and fortune. No moving vehicle or movement penalty. She sets up with spike traps, mines, and whatever else could slow or destroy their war rigs, then just starts sniping from maximum range, destroying vehicle after vehicle. It takes them a minute to figure it out, and then they charge towards her, through the mines and other traps and around the still-burning remains of other vehicles.
Despite the massive amounts of damage, they do eventually reach her location... Only top find that she's gone, having escaped through the nearby exit to the forest.
Meanwhile, with them all focused on the threat in one direction, mag sneaks in via another emergency entrance and starts rampaging, with a focus on anybody who looks to be in charge.
Whether the biomancer is in front or in back, he's not safe, and his army wouldn't be able to protect him. Furthermore, it causes heavy damage to the army and it's rigs.
Now I know this isn't really an option, and it's not very effective as an assassination, but it's pretty badass. I'd love for that to be a plan b if our initial attempt doesn't work.
The upside is that mag feels practically immortal, and our own person isn't in much risk at all.
The other upside is that if mag somehow does die, the problem of his out-of-control powers are solved.
The downside is that the biomancer isn't likely to lead the charge towards danger, so if we're not lucky with our first couple of shots, then we're relying completely on mag.
Anyways, as to the actual vote, I haven't decided yet.
