Hello Уриэль Септим Х and AlexAnt!

In MMH5.5 there are two type of stacks - mixed creatures and single-creature stack.
- mixed creatures - they are set with mood "Hostile" and Courage "Flee_join".

This means the mood specifies the certainty to attack or do something else. In this case this means they will always fight disregarding hero army size and diplomacy bonuses.

- single creatures - those are set to mood "WILD" and courage "FLEE_JOIN".

I am not completely sure what WILD means (I Could not find it in documentation) but from practical testing I believe it is half friendly / half hostile so it is susceptible to diplomacy and army size bonus and CAN be joined.

This is valid also for monster of the week creatures that appear on the map.


One can use Mapmixer to make all creatures wild or friendly (including the mixed creature stacks) so the players can have a chance to join them.
