Phantom Blade Zero Inspection Crank location

Phantom Blade Zero Inspection Crank location: the hostile Shadow Warden reached by descending from Valley Sha-Chi Tower Summit drops it. Talk to the friendly Warden at the summit first. The two named walkthroughs agree on that pickup; neither completes the later trophy quest.

1. Activate the summit Bell and accept the friendly Warden's request for a Primal Stone.
2. Continue around the upper tower to the descending ladder. Defeat the hostile Warden below and collect the crank.
3. Continue downward. Thumb Wars describes taking the right-hand route toward the shortcut ladder; the left-hand exit heads onward toward The Hunt.
4. Lower the shortcut and return inside to the furnace. Insert the crank and take its Primal Stone.
5. Remove the crank afterward. Thumb Wars explicitly includes this step; it matters for the separate Phantom Blade Zero how to get Reflex Device route.
6. Fast-travel to the summit and deliver the stone to the friendly Warden.

Do not treat the first delivery as the whole Spectral Blade quest. Later tower visits are still required. Phantom Blade Zero trophy roadmap: safe order places this opening stage before leaving the valley as a precaution; the exact failure trigger remains UNSURE.
