He teleports back home.

When he's not personally in the blast zone anymore, he'll command the first of his skeletons to Detonate.

It won't kill the skeletons, or the devils, or anyone else smart enough to have fire resistance on tap by now.

It will, however, kill the roof.

Estrella has spent several straight hours forcing people to start fires, often in their own homes and usually in ways that are suicidal.
She has developed a new fetish.
When she gets home, she'll definitely set one of her own thralls on fire, just to feel this some more.

Even a stealthy creature of the night, who is also a ranger, who is also immune to tracking and all divinations and has a false absence of magic auras, can be found if you're trying hard enough.

When they guess where she's likely to move next, and the inquisitor manages to pretend to be a commoner despite her many advantages to seeing through it, and she wastes a moment attempting to give a command, the strike team will have an opportunity to teleport in and take her out.

I'm a vampire.
I'm wearing Boots of Teleportation.
I'm immune to all divinations, and a lot of other things too.
I've got a contingency written by a superhumanly intelligent lich.
I've got who knows how many other tricks in my Bag of Holding, made by that same superhumanly intelligent lich.

You have one surprise round in which to completely destroy me or it doesn't even count.

What exactly do you think you can do here?

Aspexia and her hit squad arrive instantly by way of dimensional magic, and -

An enemy has used dimensional magic to move to within close of her.
Her Contingency immediately kicks in-

This 7th circle wizard has Counterspell Mastery, and has prepared spells with which to counterspell any of Plane Shift, Teleport, Dimension Door,  Ethereal Jaunt, Shadow Walk, or-

She's Mind Blanked and Greater Magic Aura'd.

You can't tell what spell the contingency is triggering.

You'll have to guess.

Every other caster on the team has a readied action to counterspell a different escape spell. There's only so many options.

Estrella will be hit by readied Counterspells against:
Plane Shift, Teleport, Dimension Door, Ethereal Jaunt, Shadow Walk, Anywhere but Here.
They're pretty sure she can't use Gate. If they were fighting a ninth circle there would have been a Meteor Swarm by now.

They have a list of all the dimensional travel spells.

You're not getting away easy.

It's not any of those.

Improved Counterspell: You are skilled at countering the spells of others using similar spells.
Benefit: When counterspelling, you may use a spell of the same school that is one or more spell levels higher than the target spell.

The counterspell wizard decides that you're not casting any Conjurations of at most sixth circle.

Maybe you've invented some weird variant of Teleport or Plane Shift or anything like that which isn't technically the same spell just to stop people counterspelling.

In that case, fuck you, get counterspelled anyway.

Homeward Bound (4th), is an abjuration.

Fuck you too, bye.

And she departs.

No you can't that's not allowed.

You're on the material.

The rules say you lose. You have to obey the rules.

He's right, you know.

Homeward Bound sends you back to your native plane.
It only works on extraplanar creatures.

Just to check, what exactly is an extraplanar creature?

You're native to the plane your born on, or created in.
You're extraplanar on any other plane.

Great, that's what I thought.
I'm extraplanar on the material.

Elaborate?

I was born in a Bag of Holding.
I'm native to the Astral plane.

Since when?

Since I was born.
It's in my backstory.
The third sentence.

Explain how?

Do you really need me to?
Don't you know about the birds and the bees already?

When a powerful lich wants an adoring servant very very much, he picks a human man and woman of suitable stock, and Geas's them to go into the bag of holding-
