How to protect a maze/dungeon from scry/teleport and other

[OgreBattle]

How do you guard a dungeon against the common "lolwizard" hacks of scrying, teleporting, or turning everything into mud?

To a reasonable extent, that is. What are the specific spells?

Is there a spell to force teleportation to go where you want? So they teleport into a death trap or something.

[Sigil]

Is this in the context of vanilla 3.5, Tome, or what?

I would read the Dungeonomicon. Prior to the part where 40ft blocks them is an analysis of how it works in the Raw game.

The only thing that comes immediately to mind is (un)hallow -- you can attach a rider effect.

as for affecting teleport without stopping it out right, anticipate teleportation lets you know when/where it's coming, and there's a 3rd-party spell called teleport redirect, but the origin of the teleportation must be in range of the spell.

Ban divination, use the Warp spells from dnd-wiki.org instead of Teleport, and have your dungeon walls made of something other than mud. Depending on splat saturation, your material may or may not have to be something bizarre like cloth layered several feet thick and then fireproofed or whatever. Preferably you can just make them out of metal.

Obviously the first two are more house rule suggestions than actual strategies, mostly because near as I can tell there are no actual strategies to counter scry-and-die, so my response is just to hit it with a banstick. On the one hand, this makes above-ground castles a reasonable fortification again. On the other, this means we're back to there being no reason for anyone to build a dungeon when they could build a castle (unless it's a retro-fitted mine or something).

Here's the links to the relevant dungeonomicon sections Kaelik mentioned:

Teleport section
Divination section (which has some teleport foiling in subsection 2)

Antimagic field, dimensional lock, Mordenkainen's private sanctum, false vision, dimensional anchor, forbiddance, probably other spells. I'm not sure about stopping transmute rock to mud. There is a lot of stuff in the Stronghold Builder's Guidebook that might help you.

Transmute Rock to Mud is thwarted by brickwork and general masonry.

[Wrathzog]

Healthy amounts of Arbitrarium.

Alternatively, don't let your players play Wizards if you don't want them doing crazy shit.

Also, the more stuff you prevent, the more likely you end up tricking the group into thinking that they're going up against an epic level caster.

And also by building those things around a metal cage. Which you'll want anyway to block passwall.

So... rebar to support the lead sheeting around your house (to block divinations), which is then covered in brick and mortar (because wood burns) to look pretty. And then doused in copious amounts of additional magics, because fuck you i need my privacy.
