Maximised Fireball.

They'll stop here outside of easy fireball range, and try to make themselves a bit more spread out.

They'll throw a few of their own back, just on principle, though it's not easy to hit a ranged touch attack through the arrow-slits of a well built fortress.

Flame Strike works better, for those casters who have it.

Fort Constance has batteries of catapults, and large stocks of alchemists' fire.*
A few days ago they pointed at the sea, because it's mostly a naval fortress.

They've repositioned them. It took quite a bit of manual labour, but a city has quite a bit of manual labour.

*Don't look at me like that. It's Paizocanon.

The houses they were hiding in for cover aren't going to make it.

They'll stop here, just outside of catapult range. They'll wait for the wall of fire to die down as the defenders destroy their own home town.

Soltaxin is having a nice day.

She's got no idea how that other so-called powerful outsider got himself killed.

Did you guys know I can telekinetically beat them to death with their own weapons? And I can do it while they stand on their walls from all the way over here outside range of any counterattack?

Being a kuthonite is great. Why yes we do take converts. You can sell me your soul right here and now if you want.

They're going to get their warwizards in order and prepare another massed infiltration by dimensional magic.

They'll do a simultaneous aerial attack by devils who don't care about fire damage.

They'll do an infantry charge on the walls a moment after, and put up Passwalls wherever they can to get inside.

Somebody can finally get rid of those annoying dragons.

Yeah, that sounds like how this will end.

Well, it was fun knowing you guys.
We killed a fair few of them, at least, and made them pay for what they're taking.

Teleport? Plane Shift? Getaway?
There are plenty of ways for us to get out of this. They can't exactly Dimension Lock an entire fortress.
Any experienced adventurers has a caster in the party who holds an escape plan in reserve.

We could stay here and die and let our corpses be destroyed to prevent ressurection, but then the rest of the civilised world wouldn't have anyone to hold back the monsters, would they?
Duty calls.

What about us?

We only really prepared enough teleports for our own parties. This kind of thing is, traditionally, every party for itself. I guess some of you can climb into our bag of holding at the last second?

Otherwise, give them Hell on your ways out.

They take the fortress.

In a room the exact location of which is a state secret, and which is protected by wards besides, Andoran keeps its naval reserves of the assorted flammable materials with which they've been burning every chellish vessel who gets in their way.

Codwin will pray to Iomedae for the wisdom to correctly guess what is right without having to be explicitly told it, and the courage to do it even if he'll feel terrible as a result.

He leaves the rest of his men and his people for dead, and is teleported out, and a moment later the lit fuse will reach the barrels.

Its better to blow up as many defenses as they can rather than let the enemy keep them, he's pretty sure.

I thought you guys said we could win this.

What I said was, "Running from a fight isn't what Iomedae would do. Even if it was certain death, if Her death would make a difference."

You made a pretty big difference.

I totally said they can win this.

Under the moral values of a typical Andoran as implied by their voting habits, this is a pretty big win.

We've destroyed the docks, which was the only part of strategic consequence.

We've captured the entire city.
We're putting everyone left to the sword.
We're going to take everything the city has.

How exactly are we losing, here?

Just curious, what are you planning to eat, for the next three days? Got any changes of clothes?

A lot of your current gear has been wrecked by the mud and flames.

We can loot supplies from the city.

We can conviscate food off of nearby villages.

The city has very little loot, and what does remain is boobytrapped. You'll want a caster with detect magic or arcane sight to do mine-clearing work, first.

Most of the crops were burnt in the evacuation.

We've got secret supplies hidden under the water, in sealed containers.

I noticed. You don't have those anymore.

We've brought supplies with us. It's divided amongst many small campsites.

... Actually our supplies were lost, werebear attack. We were hoping we could have some of yours? - Our cargo slave broke his leg when we were marching last night, our gear if about 20 miles up the road. We should send someone to go fetch it ...

You've got nearly enough food, if you go back out of the city to gather it all up.

You don't have enough equipment to continue fighting.
You've taken massive casualties, and those alive are mostly injured.
You don't have the best access to healing spells. It'll take several days for your injured to fully recover.

We've got a lot of wizards. We can resupply by teleport.

Yeah, you can do that. You're out of spell slots, so presumably you'll do it tomorrow morning?

Is that your plan? Spend the rest of the day moving gear from your campsites into the muddy, boobytrapped ruins of a city, by carrying it up the enbankments and over the walls and through all the obstructions you fought past to get to this mildly blown up fortress?

And everywhere you can go to take a shit has an exploding rune written on it?

Abrogail should appear somewhere and tell us what to do. We're her army.

... Abrogail's not coming back, is she?

We all think it probably best to camp outside the city tonight, what with all the boobytraps and mud and bloodied corpses. There'll be less disease that way.
