Step three: Enlarge Woljif.

Step four: Charge! Cold iron overcomes damage resistance.

Step five: Enlarged, Hasted Sneak Attack - which due to Weakening Wound halves the damage resistance as well as doing a lot of damage.

Leaving step six: Hasted Cold Iron volley of arrows! One Babau goes down.

Step seven: Tank the hit. Ouch. Nonetheless, between wearing enough metal for a French tankette, Magic Vestment, Protection from Evil, and the grace of Iomedae, it's only the one hit. 

Leaving us with another round to take the second one down. Boom!

Ok, that wasn't too bad and the Magic Vestments are even reusable. 

All that, and the door is locked? With not so much as an option to pick the lock? That's cheating.

Indeed, why is the enemy even bothering with babaus, minotaurs, and ghouls that can apparently walk through walls, when all they need is a door?

Ok I have been all over the map, including the bit hidden by the statue puzzle, and no key. Hunt-the-pixel is my least favorite form of gameplay; Google time.

All right; time to call on the Powers Outside Creation. He takes a moment to center himself, to remember the prayers he was taught as a young child - not the Christian ones for public show, the real prayers that were only to be said in the Inmost Chambers. 

Second floor, northwest corner. Watch out for the swarms.

Ok. I will admit that technically that door is not hidden and also quite large. Nevertheless this is annoying.

Locust swarms, bwah-hah-hah!

The swarms are effectively invulnerable to our weapons; but their summoner is the capstone of that arch. So, fight summons with summons: Azata, right on top of Jeslyn.

...which, see, allows Woljif to get in Enlarged Sneak Attacks from round 1.

Additionally Jeslyn will be a bit distracted by the outsider - she's supposed to be the summoner here, abyssinate (*) it! - and swing her dreadful scythe at it. Which does a lot of damage, but...

(*) Taldane equivalent of "damn", but different planar target.

...to an entity which is, ultimately, expendable. Abramo is not great with the direct damage, and will heal one of Hulrun's Inquisitors that appeared out of nowhere (although where is the man himself?) and are doing a splendid job of keeping the various demons busy.

Enlarged Lann does a lot of damage when the sonic arrows hit - lots of loot with military applications lying around this crusader fortress - but he does have some difficulty getting used to wielding a bow that's suddenly child-sized. Miss, miss, miss.

Not to worry, Elysium can fill in the cracks where Heaven fails.

...and there's the key, at long last. Abramo can only hope he hasn't expended too many of his resources in getting it. Men are dying in the front courtyard to buy him this chance; it must be attempted, win or die.

It does not occur to Abramo that one could camp in the middle of the Gray Garrison fight. It did occur to me, but I'm not going to do it; I'm just going to throw shade at the devs for apparently allowing it. Just how long is Irabeth supposed to be fighting in that courtyard?

Then once the door is unlocked, we can have a cutscene! Featuring:

Miiiiinagho as the jilted demon-lover yearning only to make her beloved see reason and abandon the friends who have already betrayed him!

Staunton Vhane as the terribly-wronged knight who still stubbornly clings to his principles, poor misguided cinnamon roll that he is!

And... in a surprise casting which nobody really thought through, but that's fine, Minagho is a professional and can improvise...

Abramo Aiello and his merry band of interlopers as - (ostentatiously does not check notes, since there aren't any, what sort of idiots are running this show anyway?) - as... all right, you know what, people who want to steal the spotlight from Minagho can at least work a bit for it. Your cue, Abramo!

Right so:

1. The "Good" option shows faith in Staunton, but it also puts words in his mouth. Abramo does not want to speak for the man, when he's doing such a splendid job of speaking for himself.
2. The "Lawful" option is back to Lawful Stupid; the alleged evidence that Staunton is a traitor is that he... spits defiance in the face of the demon currently torturing him. Come now.
3. The "Chaotic" option is a moderately sick burn, but does not actually make any sense.
4. The neutral appeal-to-Staunton's-good-sense option is at first glance the best of a bad lot, but it also tells Staunton to do exactly the thing he is already doing, to wit, not believe the demon's lies. Which is good advice but unfortunately works out to an insult to a brave man; Staunton is already disbelieving and defying her, what more does anyone want?
5. The neutral do-not-interfere option is just deeply stupid. What sort of person doesn't interfere when they come across their enemy torturing a man who has been a steadfast ally at great cost to himself?

Abramo is inclined to agree with Minagho, actually: What sort of idiots are writing this?

...all right all right "Good" it is then. Abramo will depart a little from the script to mitigate the damage; he indicates Staunton as he speaks, to show that he's not speaking for Staunton but taking him at his most recent words.

"What are you trying to accomplish, Minagho? Staunton knows you're a liar."

Bah, if you're going to improvise you should at least have some fun with it and not just play it completely straight - although perhaps he's trying to help Minagho out by being the straight man to her comedic genius? Oh well, it'll be all right on the night - no that doesn't work either, does it? Whatever, Minagho is getting paid anyway.

"The crusades are the lie! My love is as true as a flame!"

And as lasting; and as damaging. Staunton will slash Minagho's lying face and exit, stage right.
