Regarding the summoned NPCs and characters changed into Phantom

That's why I stated there weren't any VISIBLE ones, at the very least. I'm well aware that there are invisible NPCs in the game. However, he moves around the map. NPCs cannot follow characters around like that.



Good catch.

Players also can't instantiate their own NPCs in the game that change someone's class. NPCs can move around. He could have just bound its location to his player location.
