Stone Mask Evolution Vampire Survivors Unlock Requirements And Effects

The Stone Mask stands out as one of the most critical passive items in Vampire Survivors for players looking to maximize their gold income. It provides a steady boost to earnings while enabling powerful weapon evolutions during a run. Understanding where to discover this item and how it transforms your loadout is essential for long-term progression.
How to Unlock the Stone Mask
Unlocking the Stone Mask requires players to venture into the Inlaid Library stage. To gain access to this stage, you must first reach level 20 in the Mad Forest.
Once inside the Inlaid Library, head towards the eastern side of the map while staying near the top edge. The Stone Mask rests on the floor inside a small alcove between bookshelves. Walking directly over the item permanently unlocks it for future level-up pools.
Stone Mask Passive Effects and Greed Scaling
The primary function of the Stone Mask is boosting your overall Greed stat in Vampire Survivors. Each level invested into the passive increases gold coin gains by 10%.
At its maximum rank of level 5, the Stone Mask provides a significant +50% multiplier to all collected coins. Higher Greed directly increases the gold obtained from defeated bosses, breakable containers, and treasure chests. This makes it an indispensable component for high-yield gold farming builds in endless modes.
Evolving Weapons with the Stone Mask
Beyond its economic utility, the Stone Mask acts as a key catalyst for multiple weapon evolutions. Combining Gatti Amari with any level of Stone Mask transforms the playful felines into Vicious Hunger after opening a 10-minute chest. Vicious Hunger turns defeated enemies and pickups into shiny gold coins across the screen.
For players using downloadable content, the Stone Mask unlocks even deeper combat synergy. Equipping Night Sword alongside a max-level Stone Mask allows it to evolve into the formidable Muramasa blade. Additionally, pairing maxed Stone Mask with Rock Riot creates Gemma Torpor for massive area control.
Strategic Tips for Gold Farming Builds
To get the most out of the Stone Mask, consider pairing it with complementary Arcanas such as Disco of Gold. This combination converts gold pickups directly into healing while triggering massive continuous gold rushes.
You can also grab the Stone Mask as a free stage pickup after filling all six passive item slots. This strategy allows you to exceed the standard passive limit and maximize your character's potential. Stacking high Greed with additional curse mechanics yields the ultimate resource-harvesting run.
