The NPC is named. The term monster is subjective and may hurt the NPC’s feelings if used. Then again, it may be accurate.
Not specifically, but I do remember being SO confused when random enemies started changing into mini-me. I took an EQ-break when they were added. Is the NPC found in a PC starting city?
Found in a dungeon? Not sure if there is a real technical definition of what a "dungeon" is in EQ and D&D... but I hope you can answer it in good faith
