Heroes 5.5 WarGame Edition - Tactical Edition.

In my opinion, the idea is correct, but is it possible to implement it?

If it weren't possible, I wouldn't be writing this :)
You can freely adjust both the effect itself and its duration – based on skill and magic.

A similar conversion is already used in Heroes of Might and Magic V, but the rate is too low there – only 15% of magic goes into the parameter.
