Carbon paper soaked in white-out, because that's what they found in the old stock room. Then they build a fort out of their desks and chairs. Then they vie for position of emperor for a bit, shifting rule of this strange new world of their own construction through several hands. By the time a new ruler has been justly and fairly crowned, it's five or six, so they go home.
The next morning, they tidy things up a bit and test Cloudsplitter in ways that make statistics feel dirty and ashamed. I get that "it can do the same damage", but it's also a fact that melee damage is made much worse through factors that make Cloudsplitter worthwhile to use.
Cloudsplitter is not even on par with Wildfire. Not even on paper.
An empyrean weapon-skill should be an improvement, not tantamount to ripping off one arm so as to wield it as a club with the other.
