<XmlName type="1" id="
NPCCharacters" path="Rigalebandits"/>
you can find the id here, E:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\SandBox\ModuleData\bandits.xml (my install oc)
in this file the very beginning looks like this:
<
NPCCharacters>
<NPCCharacter id="looter" default_group="Infantry" name="{=urUwa4bf}Looter" level="6" occupation="Bandit" culture="Culture.looters">
so in this case, the id is "NPCCharacters", and my path is
E:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\Rigale2RoC\ModuleData\
Rigalebandits.xml
I hope this helps.
you can download the mod from here:
