Banshee Steel Sword Blueprint (The Witcher 3: Wild Hunt)

Good day everyone. Reading various options for passing on the Internet, I came across an interesting moment. Almost everywhere they write that on the first floor of the von Everek estate (Stone Hearts) there is a chest containing a drawing of a steel sword "Banshee", and not a simple one, but one that adds life points when hitting (lifesteal). Having searched the entire estate, I found nothing of the kind.
Can you please tell me if such a sword exists at all? Maybe it was removed in recent patches, but I didn't notice? I will also be grateful for the console command on the drawing or the sword itself)

As an example, here is a quote from one of the walkthrough sites: "We go into the house, on the first floor in the hall on the table, take the album with Iris's drawings. And in the chest near the passage to another room there will be a drawing: Banshee - a steel sword that restores the standard of living Geralt on blows. "
