[X] Plan Murderbeast Distraction Mk2
-[X] Sabotage the defences...
--[X] By unleashing whatever is under this floor upon the greenskins above it.
---[X] When you pass by the bolt throwers on your way out, fire them using Move.
-[X] Slip out...
--[X] By walking out while they're otherwise distracted. (note: ensure your plan includes an otherwise distraction)
Fire is fun, but too troublesome.
No reason to not unleash more destruction on our way out, it's a very simple spell, and the set up is just to good to pass up. We can kill dozens to hundreds of gobbos like this.
