Hello Arte, and everyone on this forum

I'm pretty new to runuo, scripting, and expecially XmlSpawner, but i'm learning pretty fast...
By the way, i really appreciate this system and all the possibilities it offers

Actually, i'm developing some basic npc for the shard i'm working on, an i was wondering something about the XmlMobFactions...
I'm creating new factions for player races, to put npc in them (and if i get how, also players), so that players from different races might be seen as trustworthy or hated more from the different MobFactions...
My concern is: does this system come before the IsEnemy method in npc scripts, or it overrides it?
I want the different race guards to be part of the factions, but i have some races that they must always try to kill on sight... so, if this overrides the IsEnemy, it could be a problem for the shard...
Haven't run deep tests about this thing yet...
