Giant ant queen



Killing the Marigold Ant Queen will net you 25 experience and an item, "Ant Queen Pheromones," which is an Aid item that provides PER -3, INT -3 and CHR +3.

On the table in the Queen's lair is the Big Book of Science, as well as the Doctor Lesko's field computer among other items.

X in Rivet City ponders, "If only I had some ant pheromones, that would drive him crazy."
