I have been chasing this bug since forever.

On P99, it seems that upon casting Minor Illusion, anyone watching you when you cast Minor Illusion will see your body form as whatever inanimate world object is nearest to their player character's field of vision when you cast Minor Illusion, or if you've transformed without them viewing, they may see you as your normal character model or your model at human model size. As such, I have been viewed simultaneously as a chair and also as a bunkbed by two different other players. Also simultaneously as a barrel and as a hide rug. Additionally, you gain infravision and the human faction modifier. Infravision is confirmed legit on EQ Mac, but the human faction mod is questionable for this point in the EQ timeline.

Originally, way way back in the day, Minor Illusion granted a person indifferent or dubious faction against pretty much any hostile creature. For instance, you could cast MI and sit in the very middle of most any dungeon without worrying about being attacked. The faction modifier was patched around 2003 on EQ Live because of a bug that was exploited that allowed a player to be mobile while under the faction protection of Minor Illusion. I have tested two methods I know to activate the mobile Minor Illusion bug on P99 and neither worked because of the way P99 stacks spell effects, so I feel MI should still grant the effect of making a player not-KoS to the factions affected. I have sent Faction Masta Sundawg a rundown of my Minor Illusion faction testing from the EQ Mac server while it was still active, so I hope some of the research gets put into effect some kinda soon!
