Jigeki’s Lens is linked to a hidden boss route above Obmuer Temple. Collect the three Jigeki Key parts from Deimpo Mausoleum, beneath the Ancient World bridge to Siraatsu Castle and the giant fish in Rotting Cavern. The cliff-side temple also has a separate four-tiara entrance puzzle.
Three parts, three different areas
The community guides describe the key as a three-part objective. Their numbering differs, so use the region and landmark rather than assuming “part two” always means the same place.
| Area | Landmark to check |
|---|---|
| Deimpo Mausoleum | Hidden mini-room inside the moving stone/elevator block in the spider-cave section |
| Ancient World | Below the bridge leading toward Siraatsu Castle |
| Rotting Cavern | Defeat the large fish that appears at particular water locations |
Do not substitute the reusable Trident Keys. Those operate different temple locks, even though both objectives can lead you back toward Obmuer.
Deimpo: the moving-block compartment
In the Mausoleum’s spider-cave area, inspect the moving block for a concealed compartment. The Steam guide’s author says the opening on the left becomes accessible when the pillar reaches the top. Wait and observe its cycle rather than trying to remove the block as an inventory item.
Comments also describe a stationary-pillar problem and suggest checking the main-hall mechanism. That is troubleshooting advice from players, not proof that every unmoving pillar is a bug. Recheck reachable switches and the intended block before assuming the part has disappeared.
Ancient World: below the castle bridge
Find the bridge that leads toward Siraatsu Castle and inspect the area below it. Both the Steam lens discussion and the dedicated key-part reference put a piece underneath that bridge.
This is a landmark search rather than a coordinate claim. Make a save before a difficult descent and plan your return travel first. The sources used here do not establish that every visible platform below the bridge has an ordinary walking route back up.
Rotting Cavern: the large fish encounter
The third area’s part comes from the giant fish, rather than a chest next to a normal small fish. The primary discussion and key guide associate it with particular water locations in Rotting Cavern.
If you have already searched the obvious dry corridors, switch the search to that encounter. The references do not supply a universal spawn coordinate or respawn guarantee, so this guide does not prescribe an invented farming loop.
Four Ceremonial Stone Tiaras
Return to the elevated cliff temple above the fish-man island/Obmuer area. The Steam walkthrough identifies four nearby Ceremonial Stone Tiaras and gives this left-to-right arrangement, repeated in the published NPC reference:
| Position | Marking pattern |
|---|---|
| First | Red, white, white |
| Second | White, red, white |
| Third | White, white, white |
| Fourth | White, red, red |
The tiaras open the entrance stage; the collected Jigeki parts belong to the further locked route. Read the tablets near that door before continuing. The lens discussion places the lens with the boss beyond this sequence.
Use Jigeki’s Lens with the Mask of Second Sight when returning to lens-dependent obstacles. It matters for access to a Sipeha seal route, not as another Wind Gem for Endu.
