[8][9] On August 25, one month before the album release, the band unveiled the second single "Death's Forgotten Children" featuring Tom Barber of Chelsea Grin.

Necromanteum is a marked improvement on the band's previous effort Graveside Confessions, which was by no means a poor album, but felt like it ran a little too long and dragged a bit towards the end.

"[14] Wall of Sound gave the album a score 9/10 and saying: "An improvement on 2021's Graveside Confessions, Necromanteum ranks amongst the most satisfying releases in Carnifex's back catalogue.

A band whose albums feel generally too top heavy, with the finest material loaded at the front, this ninth full length is arguably Carnifex's most consistent record to date, and will undoubtedly be a major success amongst their fanbase.

Necromanteum is an excellent, inspired sounding effort, and as Carnifex nears two decades in the game, serves as a testament to a group who are hungry to run with their peers and school the multitude of acts they've influenced.
