The perk at 300 gunpowder only seems to trigger sometimes.
It is very hard for me to tell, but it also doesn't seem to work for my troops .
The wording makes it seem like every shot should penetrate a shield, but is it actually just a chance to do so?

I've been playing with and without Improved Garrisons, as I saw some mentions of it breaking certain skills, but it doesn't seem to make a difference.

I thoroughly enjoy the mod and appreciate the effort that's gone into it. If this is just a wording issue, is it possible to alter the %?
