The Penetrator Armor In Demon's Souls is an armor set that players can get if they find a way behind a hidden door. That said, In this guide, we will explain how to get the Penetrator Armor Set and how to get past the hidden door.
How to Get The Penetrator Armor Set
To get the Penetrator Armor set, you will need to get an item called a rusty key and use it to unlock a hidden door in the Tower Knight Archstone Inner Ward.
But to get the rusty key that unlocks the hidden door, you will first need to unlock Fractured mode and farm ceramic coins that only spawn in the said mode.
As we explained in our guide for unlocking Fractured mode, you buy it for 25k souls at the Archstone, where you spawn after fighting Vanguard in the nexus. Once purchased, you can then move on to farming the coins.
When you have at least 26 of these coins, take them to Sparkly the Crow in the Shrine of Storms, and the crow will trade you them for the key you need.
After you get the key, take it back to the Inner ward and unlock the hidden door. Inside you will find the Penetrator Armor set, and it will provide you with resistance against all damage types and adverse status effects. The Penetrator Armor also looks similar in appearance to the game's Penetrator boss and has a total of four parts; helmet, Cuirass, Gauntlets, and Greaves.
