I want to flood a city with Create Water

[Drammor]

One spell will certainly not be necessary. Part of the purpose of this is to do it over time. That way, people will be terrified and panicked when they die.

[Shiki]

It may seem like cheating a bit, but a simple way of getting this done is simply to create an epic spell which will do just this... There's precedent for something like this in the freaking Forgotten Realms, albeit in an online article at wizards.com I can't recall where. It was about some lost city of Psions and/or Elans, I think. Ahh, yes. It those who died became a Psionic Vestige. Aw well.

And well, not really about the spell Create Water, but yeah...

There is always Control Weather, torrential rain for 4d12 hours creates a lot of water.

[Amechra]

Hmm...

Where is the nearest large body of water? Is it uphill or downhill in relation to the town?

[Rejakor]

Delayed Create Water could do what you want.

Or like... Twinned Enlarged Repeated... or some kind of time shenanigans... it can be done in DnD but requires TO optimization.

[Amechra]

There is no way at all to do this feasibly with Create Water unless you try to do it in a massive timeframe- it's just too expensive.

Seriously, I have a post that goes through the pricing for this.

well ive thought up a small idea. get a few wizards together that have items warding them against detection and scrying. have them use spells like move earth and stone shape to carve out the land beneath the town and fill it with water from either create water or a tunnel to a near by lake and pipe it in, then use explosive disks to blow  the celing and support structure away and sink the town into the under ground lake. walk in later to loot whats left using move earth and stone shape to clear debris. could take a while though.

A couple of water benders, a dike, a flaming arrow, and a few barrels of blasting jelly?

Sounds like the makings of a gay porn film.

...thanks

The irony comes in when you stop and realize that I didn't intend that last sentence (or even see that it was appropriate) until I had the entire rest of the post written up.

My brain just put it all together and I realized how wonderfully awful it was.
