The Traits, Talents and Toadies modification for Total War: Rome II
vastly revamps the way that your general gains
retinues, traits, and skills both in battle and in actions on the campaign map. The mod includes many features such
as a new systematic skill tree with color coded skill cards. Also generals can now gain new beneficial skills by
keeping peace and order whilst stationed in a settlement. You can view many other features
as well as the new skill tree by visiting the thread linked below.
