I have only been playing M-TW for about a week now. I have been using my emissaries, spies, assassins, and Inquisitors (when a Catholic faction) and have been very successful in increasing the valour of my assassins (up to 4 star) but cannot increase it in my other agents.
I have been unable to kill any enemy general, other than a rebel one, even with a 4-star assassin.
Can't burn an enemy Catholic general as a heretic, even though they have no piety.
My strategy is to set the conditions on the battlefield by saturating a province that I am planning on taking with my agents to disrupt as much as possible to gain an advantage.
