Whenever there's an orc invasion, someone will wing a Stygian with a spell or misclick or cleave into them and then get attacked in preference to the Orcs by an invulnerable NPC. Could these be set to never go hostile somehow, or to be killable and a different faction to the Sharb bowmen, so they'll just die in the battle rather than keep chasing someone around?
What happens then when the server population is low and the invading Orcs quickly kill those two Stygians and sit right at the transition farming lower level players?
Don't throw AOE spells towards friends in battle.
If they're already invulnerable in the first place, setting them to being plot NPCs should keep them from going hostile when attacked.
I do solemnly swear to never heal a Stygian Armada Infantryman while I know factually OOC that they won't die regardless.
They should also... turn around and face the bridge when they return after a fight... >.>
Kotenku is lame, otherwise this is for avoiding what VP said.
