All Four Triangular Slate Locations in Queen’s Domain

You’ll need to collect four Triangular Slates to unlock the entrance to Obmuer Temple in Queen’s Domain. All four are scattered around the flooded ruins outside the temple, but some can be hard to spot. Here’s where to find all four Triangular Slates in Queen’s Domain and how to use them to open Obmuer Temple.

All Triangular Slate Locations in Queen’s Domain

All four Triangular Slates are found in the flooded ruins beyond Aganmi’s Camp, outside Obmuer Temple.

Triangular Slate	Location	How to Get
Triangular Slate 1	Eastern ruins, near the circular area with red fish	Follow the eastern route and collect the slate from a rock guarded by skeletons.
Triangular Slate 2	Elevated broken columns	Climb the stone ramp and Wind Dash across the broken wall to reach the slate.
Triangular Slate 3	Southwestern flooded ruins	Cross the water using a fallen pillar and look behind another broken pillar in the southwestern corner.
Triangular Slate 4	Isolated platform northeast of the temple ramp	Double Wind Dash to the platform, avoid the skeleton ambush, and collect the slate on the far side.

Be careful while crossing the water as Coelacudas can leap out to attack, and there are groups of Red Nibblers and skeletal enemies along the route. The ideal order to collect these is 3, 1, 2, and then 4.

Triangular Slate 1 Location

From Aganmi’s Camp, head into the flooded ruins and cross the shallow water toward the broken wall. Use Wind Dash to clear the gap, then continue through the area containing several Red Nibblers. You’ll find the first Triangular Slate resting on a rock near a Skeletal Warrior and Skeletal Soldier. Collect the slate, then return toward the circular structure to continue searching.

Triangular Slate 2 Location

The second Triangular Slate is located on top of the broken stone columns near the route toward Obmuer Temple. From the circular structure, follow the other path and continue toward the stone ramp. You’ll encounter more skeletal enemies, along with a Barnacle that fires projectiles.

Climb the ramp and turn toward the broken wall on your right. Use Wind Dash to cross the gap and land on the ruined columns. The second Triangular Slate is sitting on the far side.

Triangular Slate 3 Location

For the third Triangular Slate, return toward the shallow water near Aganmi’s Camp. Progress ahead like normal but this time jump on the broken pillar to the right on your way to the area with Red Nibblers.

Use the broken pillar as a bridge and proceed ahead and you can find the third Triangular Slate in a corner, close to the water. Collect it and climb onto the fallen pillar to make your way back toward the main temple route.

Triangular Slate 4 Location

The fourth Triangular Slate is the trickiest because it’s located on an isolated platform surrounded by water. Return to the stone ramp leading toward Obmuer Temple, where you can pick up the Trident and look northeast. You’ll see a large broken platform separated from the main ruins.

Use two consecutive Wind Dashes to land on it. Several skeletal enemies will awaken when you arrive, so be ready to fight. However, you don’t have to defeat them to collect the slate. If you’d prefer to clear the enemies first, use the Azure Torch or Throwing Daggers to attack them from a safer platform before returning.

There are also two Ancient Coins on this platform, so make sure to collect them before leaving.

How to Use the Four Triangular Slates in Queen’s Domain

Once you’ve collected all four Triangular Slates, return to the main entrance of Obmuer Temple. The door is located beside the descending stone ramp near the statue where you can obtain the Trident weapon.

Approach the sealed entrance and interact with its four triangular sockets. Insert all four slates to unlock the door. Beyond the entrance, you’ll find the Cave Entrance Obmuer Temple Crystal Monument, where you can save your progress before exploring the dungeon.

Once you’re inside you will have to progress ahead and solve the Trident Key puzzle.
