Queen's Domain: Treasure Room Guide

Steam Community guide by Arceil.

Getting the First Key Stone

The first thing you need to do to begin cracking open treasure vaults is finding the key stones needed to open them. To obtain the first key stone, make your way to the beginning of Obmuer Temple and progress through the water until you reach the foot of the slope leading up to some skeletons and barnacles. From the edge of this platform, air dash onto the small bit of land with the corpse of one of Aganmi's raiders. From here, there's an opening into the temple to your right that you'll drop down into, and then a dark cave to the left.

Getting to the raider

Dark cave you need to enter
Once you get into the cave, just head straight until you reach a ledge that drops off into a large room with some pillars. A vault is opened on the other side of this room that you'll need to enter. At the back of the room is a sitting skeleton with a note next to them. Reading this note adds the Blood Key Stone to the duck lady's shop for 24 ancient coins. Now you're ready to start treasure hunting as the other two required key stones are hidden within some of the treasure rooms.

Blood Treasure Rooms

The tiers of Treasure Rooms are Blood, then Velvet, and finally Jade. There are two Blood vaults and Velvet vaults, and only one Jade vault. The first of the Blood vaults can be found in the basement area of the Tower of Knowledge. This requires you to defeat the boss of the area so you can clear out the flesh growths, but once you do you can access a room that contains a horde of candle crawlers. Upon clearing them out, the door to the Blood vault can be found in a corner with a glowing mushroom.

Inside this Treasure Room is the Rusted Greatsword. At Level 10, it evolves into Wodaso's Holy Lightning and makes the Scaled Greatsword available in the shop for 10 ancient coins. Wodaso's Holy Lightning is a somewhat slow, but very strong weapon. It's secondary attack is a powerful sweep of lighting in front of you.
The next Blood vault is found in the Verdant Hollow. The easiest access point in my opinion is by first going to the Petrified Garden and walking out of the gate that connects the Verdant Hollow to the Rotting Cavern, but getting up from the Rotting Cavern wing altar or riding up the elevator from the Verdant Hollow wing alter is also quick. Whatever way you take, there is a slope to the side of the gates that you walk up. From the ledge by the cave up there, you should see some windows in the side of the cliff face that you will air dash into just walk into the cave and the vault is to your left, I don't know how I overlooked this. Once you enter the dark room, the Blood vault door is through a doorway on your left.

Inside this Treasure Room is the Velvet Keystone.

Velvet Treasure Rooms

The first of the Velvet Treasure Rooms takes us back to the starting area of Neasied. Teleport to the Neasied wing altar. Off the side of the area with the altar is a cave on the cliff face you can enter. At the back of the small cave is then a hole you need to drop down. At the back of that room is a hidden door leading deeper into the earth. Follow this path until you reach an elevator and take it down. In the room it takes you to, the Velvet vault is just beyond the two pillars by the entrance.

Inside this Treasure Room is the Rusted Great Morning Star. At level 10, it evolves into Jigeki's Rot and makes the Bronze Great Morning Star available in the shop for 10 ancient coins. Jigeki's Rot's secondary attack is an explosion at close range in front of you.
The next Velvet Treasure Room is located in the Rotting Cavern. From the Rotting Cavern wing altar, a shrine-like structure can be seen. Following the path that direction eventually takes you to a sealed door that requires 4 dark triangular slate pieces found around the area to open (much like the entrance to Obmuer Temple) that leads to the vault.

Alternatively if you don't want to find the slates, if you can get to the area above the wing altar that has the crystal monument (such as taking the elevator from the connecting area or cestus hopping onto one of the wing altar prongs and dashing over), you can dash across the broken bridge and find a hole in the wall that also leads to where you need to go.

The final Treasure Room can be found deep inside Deimpo Mausoleum. You can find this vault by going to the Deimpo Mausoleum wing altar, taking the right door out that leads to the giant stairwell, and finding the door to the vault simply along the wall as you descend.

Take the right doorway

Inside this Treasure Room is the Rusted Leaf Blade. At level 10, it evolves into Puwema's Leaf Blade and makes the Gilded Leaf Blade and Ring of Wind available in the shop for 10 ancient coins and 30 ancient coins respectively. The Ring of Wind is a special throwing weapon that allows you to hurl discs of slashing wind out in front of you and it's max charge is 4 discs. Puwema's Leaf Blade's secondary attacks is a copy of the Ring of Wind as it hurls a disc of slashing wind and it also has a max charge of 4.
