How to buy and fill stone
Toshi’s shop sells only Marni’s Stones, which are used to farm various monsters from different locations, depending on where you plan to farm. The price of the stones varies.
Marni’s Stones I are filled with 250 monsters, Marni’s Stones II with 500 monsters.

After purchasing a stone, travel to the location where the monsters indicated in the stone’s name are found. When you kill monsters there, “kill points” (samples) are automatically added to the stone.
Note: your character must be in the location for which the stone was purchased.

As soon as you start killing mobs, the stones will automatically refill.
The stones refill one at a time, not all at once. This means the first stone will fill, then the second, and so on.
Marni’s Stones will only refill if you deal the final blow to the monster.
After refilling the Marni’s Stones, return to Mad Scientist Marni’s finest assistant, Wacky Toshi, and simply hand them over to him to receive experience in return.
| Marni’s Stones are suitable for characters level 57 and above. After reaching level 62, you will receive significantly less combat experience. |
How to track the Marni’s Stones
All empty Marni’s Stones are yellow. If a stone is being filled, it will turn blue; if it’s fully filled, it will turn red.
You can track the progress of your Marni’s Stone by killing monsters without opening your inventory. Right-click on a Marni’s Stones in your inventory and select “Counter” from the drop-down menu.
An interface will appear below the minimap where you can see the number of filled Marni’s Stones, the number of empty Marni’s Stones, and how many monsters you’ve killed to fill the current Marni’s Stone.

Great Marni’s Stones
When you kill monsters in Valencia, Kamasylvia, and Drieghan, you have a chance to drop Marni’s Toolbox.
The drop rate for Marni’s Research Box is low.
Right-clicking on Marni’s Research Box in your inventory will yield a Great Marni’s Stone, specific to the monsters where you obtained it.
It works the same way as a regular Marni’s Stone. You need to fill it with samples from the monsters it’s related to.
Once the stone is filled, you can exchange it for Wacky Toshi.
In exchange for a filled Great Marni’s Stone, you will receive a Marni’s Supply Box.
Opening Marni’s Supply Box will randomly reward you with one of the following items:
- Ogre Ring
- Ring of Crescent Guardian
- Basilisk’s Belt
- Tungrad Earring
- Laytenn’s Power Stone
- Narc Ear Accessory
- Valtarra Eclipsed Belt
- Tungrad Belt
- Orkinrad’s Belt
- Eye of the Ruins Ring Tungrad Ring
Additionally, once you obtain the Great Marni’s Stone, you’ll gain new knowledge and a title. The Great Marni’s Stone knowledge can be found in Adventure Logs – Calpheon Logs – Marni’s Great Discovery
