In Elden Ring, Memory Stones are key items that automatically and passively increase your available spell slots. If you feel your slots are not increasing despite finding these stones, it is usually due to a misunderstanding of the game’s UI, spell requirements, or reaching the hard cap for these items.

## How Memory Stones Function
Unlike many other items in Elden Ring, Memory Stones do not need to be “used” or “consumed” from your inventory.
* **Passive Activation:** As soon as a Memory Stone enters your inventory, your total memory slots increase by one. You do not need to equip them or interact with them.
* **Starting Slots:** Every character begins the game with **2 memory slots**.
* **The Cap:** There are exactly **8 Memory Stones** available in the base game. Collecting all of them brings your total to **10 slots**.
* **Talisman Bonus:** The only way to exceed 10 slots is by equipping the **Moon of Nokstella** talisman, which adds 2 additional slots for a grand total of **12**.

## Common Reasons for “Missing” Slots
If your slot count is not what you expect, check the following common issues:

### 1. Multi-Slot Spells
This is the most frequent cause of confusion. Many powerful Sorceries and Incantations (such as *Comet Azur*, *Placidusax’s Ruin*, or *Ranni’s Dark Moon*) require **2 or 3 slots** to equip.
* If you have 10 slots but equip three spells that take 3 slots each, you will only have 1 slot left.
* **How to check:** Go to a Site of Grace, select “Memorize Spell,” and look at the number of boxes each spell occupies in the menu.

### 2. New Game Plus (NG+) Limitations
Memory Stones are unique key items. If you already collected all 8 stones in your first playthrough, you **cannot** collect them again in NG+.
* Chests that previously contained a Memory Stone will be empty or contain a different item (often a consumable).
* Bosses that drop Memory Stones (like the Red Wolf of Radagon) will not drop a second stone if you already have it.
* The Twin Maiden Husks will not sell a second stone if you bought it in a previous journey.

### 3. Misidentifying the Item
Players often confuse **Memory Stones** with **Stoneblade Keys** or **Glintstone Fireflies** due to similar icons or names.
* **Verification:** Open your Inventory, navigate to the **Key Items** tab (the icon looks like a chest), and scroll down to find the “Memory Stone.” The description will tell you exactly how many you are currently holding (e.g., 5/8).

### 4. Boss Drop Confusion
There are two Demi-Human Queens in the game that look very similar.
* **Demi-Human Queen Maggie:** Located in Hermit Village (Mt. Gelmir). She **drops** a Memory Stone.
* **Demi-Human Queen Margot:** Located in the Volcano Cave. She **does not** drop a Memory Stone.
Ensure you have defeated the correct boss in Mt. Gelmir.

## Troubleshooting Checklist
If you are certain your count is wrong, follow these steps to verify:
1. **Count your stones:** Go to Key Items and count the physical Memory Stones in your inventory.
2. **Calculate the total:** Add your stone count to your base 2 slots. (e.g., 4 stones + 2 base = 6 total slots).
3. **Clear your spells:** Go to a Site of Grace and remove every single spell. Count the empty boxes. If the number of empty boxes matches your calculation, the system is working correctly.
4. **Check the Twin Maiden Husks:** Visit the Roundtable Hold. If they are still selling a Memory Stone for 3,000 Runes, you haven’t collected that one yet.

## All 8 Memory Stone Locations
If you are missing slots, you likely missed one of these specific locations:
1. **Roundtable Hold:** Purchased from the Twin Maiden Husks for 3,000 Runes.
2. **Oridys’s Rise (Weeping Peninsula):** Found in a chest at the top after solving the “three wise beasts” puzzle.
3. **Converted Tower (Liurnia):** Found at the top. Requires jumping into the second floor via Torrent or using the “Erudition” gesture.
4. **Testu’s Rise (Liurnia):** Found at the top after solving the turtle puzzle.
5. **Seluvis’s Rise (Liurnia):** Found in a chest at the top (part of Ranni’s questline).
6. **Raya Lucaria Academy:** Dropped by the **Red Wolf of Radagon** boss.
7. **Lenne’s Rise (Caelid):** Found at the top. You must use the Spiritspring nearby to land on the balcony.
8. **Hermit Village (Mt. Gelmir):** Dropped by **Demi-Human Queen Maggie**.
