True - but could you pinpoint the bulbs location if the room is lit by many other visible bulbs and this one bulb, its filament and the lamp holding it were invisible? Im not sure I could. Just like it is difficult to tell if the parking lights of an auto are on on a sunny day.posted by Hypersmurf
Even in a well-lit room, you can tell the difference between a light bulb that's on and a light bulb that isn't.
The mage in question knew this - but she wasn't interested in attacking - just getting away from an angry frost giant and a hellcat.posted by Staffan
Note that the second invisibility spell would be the general invisibility and thus be cancelled by one attack.
I agree.posted by Tsyr
I always (and still do) felt that glitterdust creates just that... glitter.

IMO, you'd get a pretty good idea of where it was, but not as good an idea as if you could see it directly. That's why I suggested treating it as 20% miss chance. You'd also not have the invisibility trouble of pinpointing the opponent with Listen - you can clearly figure out the rough location.niteshade6 said:Personaly I'd say that even in a room lit by many light bulbs, if there was a human sized light bulb in the room glowing brightly enough to blind somebody on the inside of it, I'd be able to clearly make it out, even if the bulb itself was invisible.
Malin Genie said:I have always assumed that glitterdust doesn't "render an invisible person visible" (like invisibility purge) - it coats them in sparkling glittery stuff, which is visible (due to the nature of the spell) despite the fact that it is in contact with an invisible person
(unlike, for example, their clothing/equipment/items they pick up/possibly spaghetti suauce which is thrown on them {depending on your rules interpretation} which all becomes invisible with the person.)
