About this mod

(Updated to e1.8.0) A mod that allows you to adjust combat AI.

Permissions and credits
Improved Combat AI
(Old name: Enhanced Mission Change AI)
A mod that allows you to adjust combat AI level..


  • Combat AI level is a value in the game used to determine the soldier's combat ability. With higher melee ai level, the soldier can block better, attack more ferociously and dexterously. With higher ranged ai level, the soldier shoot more accurately.
  • This mod allow you to adjust that value.
    • By default combat AI level is determined by the weapon skill of soldiers: the combat level are equal to his weapon skill divided by 3.5.
    • So soldier with weapon skill of 350 has the highest 100 combat AI level when using corresponding weapon.
    • Given the melee AI difficulty "x" set in this mod, the melee AI level will be divided by "1 - x/100".
    • For example, if a soldier has 100 one-handed weapon skill, and when he uses one-handed weapon, by default his melee AI level is 100 / 350 * 100 = 28.57. If the "Melee AI Difficulty" is set to 50, then his melee AI level will be 28.57 / (1 - 50/100) = 57.14, that is, doubled.
  • Besides improving every soldiers' AI level, you can directly set combat AI level of every one directly.
    • Then the weapon skill will be ignored when determining combat AI level, and all units will have the same combat AI level you have set.
  • Adjust ranged lead error. The value is used when aiming moving targets. 0.2-0.3 is the best value as I tested. Set this between 0.2-0.3 so your archers can hit the enemy horse archers.
  • Realistic blocking.
    • Realistic blocking is the blocking mechanism that introduced in Beta 0.8.1 and removed in Beta 0.8.4 in Multiplayer mode.
    • Now in Single-player, It's only enabled for all the other characters except the player by default.
    • If you enable the option in this mod, then player will use it too.
    •  With realistic blocking enabled, you block slower if for example your weapon is on the right side and you want to block on the left side.
    • Here is the description from official patch note b0.8.1:
    • "Actual defence starting moment after clicking the defend key now relies on a directional distance to the target direction instead of animation progression."
  • Configuration saving. The configuration is saved in directory `(user directory)\Documents\Mount and Blade II Bannerlord\Configs\EnhancedMission\`.
  • The main config is saved in file `MoreOptionsConfig.xml`.
  • You can modify them manually, but if you edit it incorrectly or remove them, the configuration will be reset to default.

  • RTS Camera  Not requered any more. But if you use it, please make sure it's version is e3.9.15 or higher.

How to install

  • Please install the prerequisite mod: RTS Camera.
  • Nothing special. Copy the "ImprovedCombatAI" folder you downloaded into Bannerlord modules folder(For example "C:\Program Files\Steam\steamapps\common\Mount & Blade II Bannerlord\Modules"). Or use Vortex to install it automatically.
  • Or use Vortex to do it automatically.
