Invisible Darkness? Invisible Light?

[Captnq]

Okay, so I got a guy who wants to make see invisible goggles for everyone in the party, then make an Invisible Spell Widened Light Source so that only people who can see invisible can see it, thus allowing him and the party to see everything out to something like 180 feet, but nobody else will know there is any light. I forget his exact math. Any reason why this won't work?

Conversely, he wants to make a pair of boots that make you invisible, that have Invisible Spell Fog Cloud on them, so that if you do look with see invisible, you'll see the invisible cloud, not him in the middle, which he figures would also block true seeing, since the fog is there, it's just invisible. Am I missing something here?

It's debatable that the invisible light source thing might not work as he thinks. It might be like a light that's out of sight (around the corner, etc). You can't see the light source itself, but you can still see the light from it.

Edit: Rules of the Game talks about invisible light sources.

Invisibility effects don't make light invisible.

When you receive an invisibility effect, any light source you carry still sheds visible light, but the object itself becomes invisible if you're wearing or carrying it when you receive the effect.

There is however a spell that does explicitly what he wants (with the light source thing). I'll have to go look up the name, though...

Edit: Well... it's not as good as I remembered, which is probably why I never used it... The spell is Darklight.

The invisible fog to block against True Seeing works as planned. We're actually using that in a PbP game I'm in right now. We filled an area we're defending with Invisible Guards and Wards, so it is full of invisible clouds.

Oh no no no...

Not, Invisibility The Spell... Invisible Spell.

You can modify any spell you cast so that it carries no visual manifestation. All other aspects of the spell, including range, area, targets, and damage remain the same. Note that this feat has no bearing on any components required to cast the enhanced spell, so the spell’s source might still be apparent, depending on the situation, despite its effects being unseen. Those with detect magic, see invisibility, or true seeing spells or effects active at the time of the casting will see whatever visual manifestations typically accompany the spell.

Would an Invisible Spell Light Spell illuminate an area normally to someone who could see invisible, or am I missing something?

I thought that's what you meant, but didn't remember the wording of the feat, and assumed it would work like casting Invisibility on a torch or something. Now that I read through the text, I agree that it probably would work as your friend wants.

The invisible fog cloud would work just fine against true seeing, but it wouldn't against see invisibility.  The fog cloud would appear as a translucent shape.

nice. i could see this tactic being really useful on light sensitive types in a number of odd ways.

Aha. It would not stop seeing visible objects, but if I was an invisible object inside an invisible spell fog cloud, would I not be just as translucent, and thus concealed? I will agree, the invisible spell fog cloud would not block someone from seeing normal things.
