The past burns (Afina, Tryll)

[Ebiris]

'The layout's more open than Hopelorn,' Afina reports telepathically after her indeterminate absence. 'Long hallways running the perimeter, probably on every floor. They're dark with invisible creatures guarding every ten feet.'

Isn't that perfect distance for a contagious fireburst? Hmmm...

'We may have to go more blatant with our attack, I can't think of a way to get all four of us past there. Let me check from an aerial vantage first, and can you examine what magical defences are in place Tryll?' She'll also cast See Invisibility while he's keeping their sounds from escaping the area.

It's probably dimensionally warded but stranger oversights have happened. While he does that she accelerates herself fast enough that her appearance in the open won't be spotted, flying straight up above the castle to look down at it and briefly study its layout before she drops back down to rejoin the others, cutting through a hallway so she can have a look at just what the invisible humanoids are precisely.

As Afina plots of firebursts spreading like Simmer's daydreams, she flies up. The castle is a boxy diamond at heart, with lots of tall towers. Nothing too fancy there, with a center that's perfectly distant from all sides. In the halls, you can see eryines stand at the ready, longswords in hand.

[Ebiris]

While waiting on Yuth doing some spellcrafting, how big is the castle? Like how far from an outer wall to the centre?

[Anastasia]

A couple thousand feet. It's maybe a mile in total area taken up, more or less. It's big.

Requesting 1d20+40 roll for psicraft

[Ebiris]

[20:11] <@Ebiris> roll 1d20+40 psicraft
[20:11] <Kobot> Ebiris rolled 1d20+40 psicraft --> [ 1d20=7 ]{47}

[Anastasia]

The area's warded to prevent teleportation, of course. Also unhallowed with a see invisibility spell that benefits everyone within.

[Yuthirin]

Tryll shares this information with the group.

[Anastasia]

'Willah relies more on bodies than magic to protect herself,' The Master observes.

[Ebiris]

'The way she's laid it out I could bring down the castle with two spells,' Afina says, sorely tempted to do just that. 'The warding against teleportation, is it total or is there a gap to allow devils or those with keystones or the like through?'

[Anastasia]

To answer since you psicrafted: There isn't.

[Yuthirin]

'It appears to be total. I saw no sign of loopholes or permission in the ward.'

[Ebiris]

'Alright, in that case we're going to be blatant about things,' Afina says, smiling a bit savagely at the prospect. 'Willah's almost certainly at the centre of the castle - it's the most defensible spot, but devil psychology wouldn't allow for anything less regardless. Once I bring the walls down we'll charge across the rubble straight there. Move away from the walls a bit and keep at least ten feet away from me,' she asks, casting planar bubble on herself and starting to burn with a primal connection to the plane of fire.

With that in place she phases back through the walls, stopping square between two of the carefully equidistant erinyes manning the hallways. They barely have a chance to notice Afina before she explodes however, stopping time so she can flee back outside before the cascading chain reaction brings down the castle!

Using Searing Blistering Contagious Pyroburst
[21:02] <@Ebiris> roll 1d20+28 SR
[21:02] <Kobot> Ebiris rolled 1d20+28 SR --> [ 1d20=18 ]{46}

Does 220 fire damage, ignoring all resistance and immunity (probably hardness too?) DC 37 reflex half. 15 foot radius burst, anything killed by it promptly detonates for the same damage with the same SR and DC as the original, with the same chance of spreading to anything it kills.

Anything that survives but failed its reflex save takes a -2 penalty on attack rolls and checks for 1 round

As soon as Afina lets that loose she time stops for 1 round (6th level slot) and flies back outside, concentrating on changing her control winds to tornado conditions within a 960 foot radius with an 80 foot safe zone surrounding her. DC 30 fort to negate wind conditions which otherwise functions like so.

[Anastasia]

Just out of curiosity, how you applying all that metamagic to a 10th level spell?

[Ebiris]

Searing is +1 and I have 11th level spells. Blistering is a 3/day freebie from my hat
