Nechryael are demonic creatures typically assigned as Slayer tasks. They require a Slayer level of 80 to be assigned and are often found in Slayer dungeons and the Catacombs of Kourend. These monsters have high Hitpoints (HP) and can deal significant damage to unprepared adventurers. However, with the right approach, they can be lucrative Slayer targets.
Nechryael can also be found in the Catacombs of Kourend. This area is multi-combat and offers a chance to earn Ancient shards and Dark totem pieces.
