The Blasphemous Blade is a greatsword category weapon in Elden Ring. To get it, you must defeat Rykard, Blasphemer Lord. After finishing the God-eating Serpent in the Volcanic Mansion, go to the Roundtable.
Where to find the Blasphemous Blade?
As said, the weapon is available after killing Rykard, Blasphemer Lord. Before doing so, complete all quests in the Volcanic Mansion on Mount Gelmir. This way, you will prevent NPC quests from being canceled.
After defeating the God-Eating Serpent, you will earn the Nonconformist’s Remembrance. Go to the Roundtable and deliver the item to Finger Reader Enia.
The Souvenir contains two options, and you can only choose one. One is the Blasphemous Blade, and the other is Rykard’s Grudge spell.
Duplicating the Nonconformist’s Remembrance
If you want both Remembrances of the Nonconformist items, look for the walking mausoleums. Upon entering the structure, it will be possible to duplicate some Boss Remembrance. (Click on images to enlarge).
Most mausoleums will have white patches on their paws. Hit these parts so that the structure falls to the ground, thus releasing entry into the place.
Each mausoleum is for single use. If you’ve already duplicated a Remembrance in a mausoleum, you’ll have to look for another. Each Souvenir can also only be repeated once.

The Blasphemy Blade’s greatest asset is its ability to recover HP. When using Marauder’s Flames skill, you will recover health when hitting enemies. The more opponents are hit, the higher the VP received.
An advantage of this skill is that it is unnecessary to kill the enemy to recover health. Each hit grants the caster HP. The problem with Marauder’s Flames is that it’s not a quick skill. Animation timing can get in the way a bit.
The Blasphemous Blade is a unique weapon and can only be upgraded with Shadowforge Stone. So it goes up to level +10.
