Military traditions location

Army tradition and navy tradition (collectively military tradition) are long term, floating measures of the pool of experience of a nation's military forces on land and sea. They give bonuses depending on their strength, are gained through actions of the appropriate forces and decay over time if not increased. Army tradition provides higher morale and quicker manpower recovery, and naval tradition provides higher morale and better trade steering. High tradition significantly improves the skill of recruited military leaders.

Gaining army tradition[edit]

  • Battles are the primary source of army tradition for small and medium-sized nations. You can view how much you gained in any particular battle on the battle result screen. The exact formula for tradition gain is not currently known, but you get more tradition the more losses you suffer, relative to your total force limit. Losing a battle will cause you to gain more tradition than winning.
Certain ideas increase the amount of military tradition gained from battles:

  • Fulani ambition
  • Each successful siege grants +2 army tradition, based on the fort's level versus the max fort level for the sieging army. For example, if the max fort level is 4 and you siege a level 4 fort, you will get 2 army tradition. If the max fort level is 4 and you siege down a level 2 fort, you will get 1 tradition. This is the primary source of army tradition for larger nations.

Gaining navy tradition[edit]

  • Battles are the primary source of navy tradition. You can view how much you gained in any particular battle on the battle result screen. The amount of tradition gained in battle is directly proportional to the casualties inflicted on the enemy, as well as the relative strength of the nations involved. Small weak nations will gain considerably more tradition when fighting large strong nations. The number of ships that you send into battle, the losses that you suffer, and the quality of your leader have no observable effect on your naval tradition gain.
