One pair per color
Keep the same pairs on green, gold and orange routes across all three rooms. That makes moving layouts easier to read.
Salvation's Edge

Assign one pair to each route. Kill all three Tormentors; the final blow grants Stolen Favor for reading that conductor.
Call Pyramidal, Spherical or Hexahedral, then bounce the corresponding plate pair and collect up to three Resonance.
The conductor-side player finishes on the called shape, shoots the pillar during transit and catches the final ring to close it.
Close all three conductors and bank every stack at the center altar to extend Final Shape Looming.
Kill the Unstoppable Incendior at the exit and advance. Clear the same loop in all three rooms.
The selected map and this mechanic brief stay on the same encounter.
ENCOUNTER 03
Repository repeats one disciplined room loop three times. The only changing information is each conductor's called Resonance and the geometry of the next route.
Keep the same pairs on green, gold and orange routes across all three rooms. That makes moving layouts easier to read.
The Guardian who kills a Tormentor receives Stolen Favor. They immediately inspect and announce their conductor's shape.
A final pickup changes the entire stack. The conductor player can collect freely, but must finish on the called shape before locking.
After banking, clear the add wave and Unstoppable Incendior at the back door. Only then does the next room unlock.
