Narrated walkthrough

Door service antechamber from its entrance — Door service antechamber: how to solve it

Getting there

Chapter 5, on the lowest floor, off the Deep protection complex hall through the arch signed Door service antechamber. The same passage continues past its arch to the alignment records room.

What is wrong

Room card: "The service door swings shut; its replacement handle belongs on the far mount." The spare handle rests on its cradle on this side, and the empty mount is beyond the door.

What you can work

Door: The service door. A return weight swings it shut whenever it is let go.
Sill: The stone sill that the door's lower rib passes over when the door stands open.
Eye: A fixed iron ring high on the wall, on the side the door opens toward.
Handle: The spare door handle on its cradle.
Mount: The empty handle mount beyond the door.
Reading lamp: Optional light to read by.
Reading shutter: Optional second light angle.

Solution

A nudge

Your push swings it fully open for about two seconds. After that its return weight starts pulling it shut, slowly.

The full solution

Handle the Door.
Your push swings it fully open for about two seconds. After that its return weight starts pulling it shut, slowly.
What you see: "The door opens against its return weight."
While it stands open, cast Brace (Growth, Growth, Growth) at the Sill.
A strut on the sill under the open door's lower rib stops the return weight from closing it. The door rests partly open on the prop.
What you see: "A compression prop holds the lower rib clear." The card shows: the service door is held open.
Handle the Handle on its cradle.
You carry the spare handle to where it belongs.
What you see: "You lift the replacement handle from its cradle." The card adds: the replacement handle is in hand.
Walk through the doorway and Handle the Mount.
The mount is behind the dogleg wall and the door, so it can only be reached from the far side.
What you see: "The carried handle seats in the far-side mount." Then "Door service antechamber settled."

Other ways that work

Tether (Growth, Growth, Will) cast at the Eye while the door is open runs a taut line to the door against its return weight: "A taut line opposes the return weight."
Anchor (Growth, Growth, Water) cast at the Door while it is fully open cuffs it to its open bearing pad: "The door cuffs to its open bearing pad." A door that is not open far enough refuses: "The door has no supported contact for the cuff here."
No spell at all: pick up the Handle first, then Handle the Door and walk straight through while it is still open, and seat the handle in the Mount. Handle the Door again from the far side to come back.

Watch for

Brace and Tether both need the door already open. Cast too late and you get "the door has swung too far shut for its lower rib to lie over the sill" or "...for a line to reach it".
A strut against the door's face, a passing push (Orient, Directed impulse, Draw) or Lighten does not hold it. Only the sill, the eye or a cuff at the bearing pad do.
On the hand-only route, take the handle before you open the door: the door is open longest straight after your push.

If it goes wrong

Nothing in this room can fail. If the door shuts on you, Handle it again.

Achievements here

The Door Serviced: Solve the Door service antechamber.
No Brace Needed: No Brace Needed: settle the room without any spell taking hold in it. Handle the Handle first, then the Door, walk through at once, and Handle the Mount. Your push holds the door wide for about two seconds, and it then takes several more to swing shut, which is enough at walking pace. What breaks it: any spell the room accepts, including a Stilling ward, Heat on the reading lamp, Orient on the reading shutter, or a spell that acts on you (Boost jump, Hasten, Rising draught, Short traverse) cast inside the room. Casts at decorative furniture or wall torches, and casts that shed or unravel, do not count.

Spells used
