When a creature is summoned with the NWN engine it, as far as I can tell, always faces away from the summoner and towards the enemy.
Can this facing be used in character to determine if one of your allies summoned the creature or your opponent?
For example, if a large group of undead is charging towards your group, the mage casts a spell, and all of a sudden an undead creature is standing beside the party and facing the enemy undead, would you IC be able to figure out that creature came from your party?
Thanks
