How to Unlock Weapon Memories in Blasphemous 2
Weapon Memories is unlocked by talking to an NPC named Yerma, who can be found in the Profundo Lamento area. This area is located beneath the City of the Blessed Name. As you progress from the City of the Blessed Name, you will descend to the Profundo Lamento area. You need to drop down a couple of levels and instead of going to the left side, you need to go to the right side to enter a small area filled with the bodies of Ruined Knights.
As you progress, you will have to defeat a Ruined Knight enemy. After defeating the Ruined Knight, Yerma will appear in the room. She has a green cloak on her and is carrying a mace. Talk to Yerma and you will unlock the Weapon Memories system.

Once you have unlocked Weapon Memories, you can access it from the Inventory. Press the ESC button and switch to the Weapon Memories tab. By selecting the Weapon Memories tab, you can unlock new combat abilities and techniques for your weapon by spending Marks of Martyrdom.
The complete skill tree of the weapon is divided into three tiers. To unlock more powerful combat techniques, you will need to track down Bearer Penitents. The higher-tier combat techniques will require more Marks of Martyrdom, so make sure to defeat enemies and bosses to earn Marks of Martyrdom quickly.
