Just to remind everyone, there appears to be a catch mechanic that allows for one unit to stop another unit from taking fall damage.
http://www.erfworld.com/book-1-archive/?px=%2F070.jpgwhile the example is an air to air fall, it is possible that it would allow a unit on the ground to catch a unit falling from the airspace. I doubt a small unit can use it to catch a bigger unit, (I'm guessing the small unit gets flattened, (ansom vs. Bogroll,)) but that isn't a problem here because all GK units on the ground will be heavys or flyers.
Jack, Wanda, and the warlords (KC, Silvia, Ossomer, and maybe a few too low level to be listed by Parson as being considerable candidates for chief warlord after Ansom's capture) are not stuck in airspace. Problem is, from the tower, Jetstone can see and shoot anyone left in airspace after the dwagons/hobbos hit the ground preventing the catch from being safely used. "Let's do lunch" is going to prevent this.
Think about the phrase. It means meeting somebody to discuss something over food. It has to be something directed at the Jetstones parleying in the tower, the same ones who can kill anything left in airspace.
I'll say this bluntly because the logic behind this idea is too long. "Messy foodstuff, like flan or key lime pie, will be used to cover the zone boundary between tower and airspace. That will block the line of sight of anyone in the tower and prevent them from firing accurately." We can now safely get the casters and warlords down thru the catch mechanic.
Getting the casters and warlords on the ground, allows for alot of possibilities. If I were Parson, I would start by croaking all incapacitated fallen dwagons and hobos so they can be quickly decrypted. Next, because Jetstone will almost certainly be targeting Wanda, I create a fake target. I give Silvia Wanda's clothes (including the hair helmet, and maybe some of wanda's warpaint if she carries a supply on her.) Some cheap foolamancy will probably be required to hide the fact that her stats don't match Wanda's and to disquise her sword as the ArkenPliers as I don't want to risk them in a decoy ploy. (This is if I were Parson. If I were me, after hearing her account to Ossomer (ignore how I would have this knowledge,) I would check to see if the pliers come apart like quite a few I've seen do. After Silva talked to Ossomer, it became a personal Epileptic Twee of mine that says that the pliers were meant to be wielded by two people, and the other person is Silvia.)
While Jetstone is chasing after the false Wanda. I have Jack and Wanda make their way to the portal room using what ever tactics they find best. (Giving more specific orders than that is overmanaging IMO. All Jack and Wanda should be told that while having troops secure the portal room would be definately a good thing to have happen, the most important thing is that they both make it there, with foolamancy if needed. Jack should the one who gets to make the call on how they should accomplish this task, but I don't say that to avoid putting tension between the two of them. They can think hard and get Maggie's attention if they need me to settle a dispute.)
Once Jack and Wanda have secured an escape route, it is time to do some damage.
