Can you point me in the right direction of how you got the MaxSummons value to be increased with the Undead Overlord skill? I have tried status in story scripts but I cannot find how to increase a characters MaxSummons value. I have also tried using the character scripts for this, but it seems MaxSummons is not considered an ability.
The API documentation is not very helpful either. There isn't any reference to MaxSummons anywhere on docs.larian.game.
