I use my smartphone to call the orbital Tradestar, and buy a rocket containing 9000 free crabs.
[4] The rocket arrives from the sky and belches forth a massive tide of mushed crab parts. The universe becomes unable to deal with so many entities and begins deleting parts from the members of the two armies present (and everyone else.)
[5] scourge is unaffected.
[2] bloop_bleep's limbs crumple into gibs!
[4] wierd is unaffected.
[6] Parts of crab fly into me and I subsume them into my body, becoming a crab-man!
[4] Inquisitorial squad 1 loses a single member to free crabs.
[1] The flying Xcrab partsX strikes the Dwarven Army in the everything and it explodes in gore!
[5] The "Heavy Inquisitors" (are you sure you don't mean Arbites...?) are unaffected, as the crab bits simply bounce off their heavy armor.
[5] CrocAndBearLover blocks the crab damage with his godly GM powers. Not that it would be a large hinderence if he had been hit.
i like dice
Edit:
"Well, this seems like a good time to..... leave until I can get the various Knights and Infantries....... HOLY VANISHING" *portals away back to Valve HQ and closes the portal afterwards so no one can follow, and if they do the Portal Knights will slaughter them*
[5] You rip a portal open and step through it, and it closes right behind you. Smooth. Usually doing that sort of thing allows AT LEAST five demons into reality.
The valve crown guards lower their steam halberds and shout "Halt! Who goes there!?"
