- "This kind of horn is common to mid-level demons. If the wrong person touches it, it can simply absorb all their energy at once."
- — Atelier Meruru description
The Devil Horn is a material found in Atelier Meruru: The Apprentice of Arland.
It is a relatively rare material because of how uncommon it is to find. It can only be gathered at the Endless Corridor in the game's later years. It can also be purchased at Astrid's shop or found in a few specific enemy drops.
It is one of few material options for both the "mystery" and "poison" categories when synthesizing.
