A fair few forumites were clairvoyant enough to predict this after we added Ruler Personalities. Indeed, as part of the upcoming expansion we will have Leader Traits
At the conclusion of any battle the leader involved has a chance to gain a trait. This trait will, unlike Ruler Personalities, always be a bonus. Current chance of gaining a trait is set to 2% multiplied by the Army Tradition gain from a battle (this, like most numbers during development, is subject to balance changes) which can be set in the defines.
Leaders are limited to one trait each and that trait will affect all units under their command. In battle, the trait of the commanding general (the one whose shock/fire pips are used) will affect all units on their side.
Some of the traits:
Goal Orientated:+10% Movement Speed
Hardy Warrior: -20% Attrition
Siege Specialist: +15% Siege Ability
Born to the Saddle: +50% Cavalry Flanking Range
Of course, Admirals can gain traits too. Same rules as generals except the chance is based on naval tradition from battles.
Buccaneer: +25% Privateering Efficiency
Prize hunter: +5% chance of capturing enemy ships
Ironside: +5% Ship Durability
Extortioner: + 15% Light Ship Trade Power
There are 22 traits in total, many with combat modifiers which have been added to the game for use in modding (and in National Idea changes which we will show later). It's worth noting that Heirs, Monarchs, Conquistadors and Explorers can also gain traits from combat.
Leader Traits are a paid feature in the upcoming [name removed] expansion. There are many more features and changes to come but you're going to have to hold out for 5 weeks on more news since as I mentioned, this country is going to shut down for a month. I'll be back with the next dev diary in the first week of August.
Great generals are like Swedish Summer, never lasting quite as long as you want.
