To throw a monkey in the works...

[Ferret]

I waited until the "Rules of the game" had covered invisibility before I brought this up.

If you make a wall or door invisible can you see through it? I'm asking purely because I saw this question on the WotC board before it was cleaned up (at least 2 years ago) and was simply wondering.

Very creative use of the spell. I like it.

Assuming you can in fact turn the object invisible, you could see through it. It would be fun if their were monsters on the other side who assumed you had destroyed the door somehow... I can see all sorts of arrows and spells slamming into the door!

 

[Patryn of Elvenshae]

You could see through it, but you would not have line of effect. So, no casting spells through an invisble door.

IANARL (I am not a rules lawyer), so I'm uncertain of the accuracy of this statement.

If that were the case, it might bring up some interesting implications, as one must assume that the spell would simply fail.

"Wow, he must be one powerful Wizard! He disintegrates the door and we can't even cast our spells against him!"

I kind of doubt I'd adjudicate it this way in my games. I'd probably rule that one can cast spells normally (after all, you can see them), but that any ray spells or things like that (Fireball, etc) would impact the invisible door first. Spells than manifest at a distance (Summons, etc) would work normally.

But what do I know. Someone will come along shortly and tell me just how wrong I am.

Don't mind if I do.

From the SRD:

Line of Effect: A line of effect is a straight, unblocked path that indicates what a spell can affect. A line of effect is canceled by a solid barrier.

Edit: Looking through the invisible door should grant an automatic Spot check.

Hidden Doors

We've found something a little confusing when it comes to invisible objects; the spell sequester "renders objects invisible as the invisibility spell." Thus according to the spell, "sequester can mask a secret door". If the bookcase was actually a door and you made it invisible.. wouldn't that make it all the more obvious since the passageway just lost what was concealing it?

Thanks,

It would.... But...

Sequester
Abjuration
Level: Sor/Wiz 7
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: One willing creature or object (up to a 2-ft. cube/level) touched
Duration: One day/level (D)
Saving Throw: None or Will negates (object)
Spell Resistance: No or Yes (object)

When cast, this spell not only prevents divination spells from working to detect or locate the creature or object affected by sequester, it also renders the affected creature or object invisible to any form of sight or seeing (as the invisibility spell). The spell does not prevent the subject from being discovered through tactile means or through the use of devices.

Creatures affected by sequester become comatose and are effectively in a state of suspended animation until the spell wears off or is dispelled.

Note: The Will save prevents an attended or magical object from being sequestered. There is no save to see the sequestered creature or object or to detect it with a divination spell.

Material Component: A basilisk eyelash, gum arabic, and a dram of whitewash.

I don't see anything about secret doors...

Have you checked the PHB? Often examples like that are left out of the SRD.

There was a cantrip in 1E Unearthed Arcana called 'Hide'. It was supposed to be a low-powered Invisibility - the caster could make a creature or object invisible, but only to creatures in front of him. Someone standing beside or behind the caster would see the Hidden creature/object normally.

The problem with casting Invisibility on a door is that while it lets you see what's in the room, it lets everything in the room see you, too. But with Hide, the caster could stand in front of the door, facing the party, and Hide the door over his shoulder.

To the party, in front of him, the door becomes invisible. But to the inhabitants of the room, behind him, the door appears as normal.

Coolest cantrip ever.

It's in the 3.5 PHB.
