although if all the swordsmen are defeated, what's the problem?
This is just as a challenge – to conduct the same battle with only 1 fake without using a blessing. There are possibilities for this, but I wanted an optimal solution without trying out too many combinations.
Besides, there will be problems with damage distribution, like each swordsman dying at a different time, which creates different scenarios for how to act. Although killing one is already 60% of the victory, in my opinion.
