WMD Spellcasting for D&D 3.5e and Pathfinder

[TachyonBlade]

So, as the title implies, how would I get close or above the destructive power of modern WMDs, with a Level twenty wizard?

Now, I'm giving free reign with his previous actions and feat/spells/other stuff that he has gained.

Oh, and spare the nub/noob the extremely complicated wording, please?

Apocalypse from the Sky[Book of Vile Darkness] plus some sudden metamagic feats[Complete Arcane] should fit the bill. You might want to have some energy resistance, damage absorption, and a way to avoid/quickly heal ability damage and drain handy.

Quite handy...

Oh, also, is it possible to scroll up two Gate spells to the Negative Energy Plane and the Positive Energy Plane to basically do the same thing?

There's always the Wightocalypse, which is like germ warfare gone even more horribly out of control.
(Short form: Wights are intelligent, hate all living things, can one-shot a level 1 peasant, and anyone they kill turns into another wight. Use Control Undead on one, drop it in a city you want destroyed, wait a day or two. Shadows are even worse, since they can't be killed by mundane means and are sneakier.)

On that note, for boring old regular germ warfare, there's spells like Contagion.

This is actually true for any intelligent undead with the create spawn ability. So you can also use this with Shadows (http://www.d20srd.org/srd/monsters/shadow.htm). Shadows are far scarier than wights by virtue of incorporeal, so you need magic to hurt them, they can walk through walls, and if they find themselves outclassed, they can hide INSIDE the ground.

However the Wightpocalypse is easier to setup via the Fell Drain Flash Frost Snowcasting Locate City Bomb.

Here's a silly one, probably one of the nastiest magical WMDs you could unleash:

Use Teleport Through Time (http://www.wizards.com/default.asp?x=dnd/pg/20030409b) (you can make it componentless through some tricks to get epic feats for Ignore Material Components, or if your DM allows it, just use Eschew Materials) to return to some arbitrary point in the past, possibly even the beginning of time if you like.

You will need a psion ally, possibly a cohort gained through leadership. Have him drop a Mind Blank on himself. You ready an action to cast Imprisonment on the psion the moment he finishes manifesting his next power. He will manifest Forced Dream, then get stasis'd under the ground. Next, your wizard uses Teleport Through Time to return to the present/future, just after you left in the first place. Use Freedom on your psion minion, at which point he will resume his turn and use Forced Dream to reset the timeline to the start of the turn... Which is innumerable years in the past.

Result: total timeline annihilation, sidestepping Teleport Through Time's clause about paradoxes and changes smoothing themselves out.

You'll probably want to get a crafted contingent Teleport Through Time to take you back to before you Imprisoned the guy, so you don't get erased as well.


Another especially silly (mostly because of involving physics) large-scale one is to get a self-resetting trap of Time Stop and a riverine Decanter of Endless Water hooked to flow into the space between two nested riverine spheres. Get an ageless being of some sort, preferably one immune to gravity somehow, to trigger the trap while holding the decanter. In an instant, you'll get a black hole from the effectively infinite amount of rounds the decanter has been pushing water into an unbreakable container.
