The true specification of "fly"

[PzKwIVG]

In case of the map which maximum dice number@is "even@" (e.g. Dunnan, Durhan) ,
when you cast "fly", total dice number you get goes out only "odd" !!!

For example, the map you choose is Durhan(maximum dice number is 8) , and when you cast fly,
you can get either total dice number -3, 5, 7, 9, 11, 13, and 15.

In Japan, this phenomenon is very famous, and it is called "3-fly".

The survey data are below.(Culdcept 2EX in Japanese version is the same one of "Culdcept" in the U.S.)
