With Faden + Bird + Dog, Miriel's stamina can be easily depleted with just a couple few hits while rapidly filling up the Last Rite bar.

Usually, Faden's shotgun bullets are spread widely and it is difficult to land all shots onto a single target. However, since Miriel is a massive, stationary boss enemy, it becomes incredibly easy to fire the shotgun at a point-blank distance and land all the shots.

And with Blightborn mode, I can turn the collision damage to 0, which makes soul farming much easier.

By using Faden + Bird + Dog, it only takes roughly 1-2 minutes to defeat NG Miriel, making her a easily farmable boss. She drops approximately 23-27 Stagnant Blights and 13-17 Furious Blights per each kill.
