How to find and beat the Bloodedge Demon in Nioh 3
Pcgamer notes the Bloodedge Demon is the most unique boss in Nioh 3 because it scales based on how many revenants you've killed. The demon spawns periodically and must be summoned by interacting with its bloody grave — a large sword surrounded by a purple glow that appears in a random location on the map.
You'll know the Bloodedge Demon is active if a shrine tells you it has appeared or if a slain revenant leaves a red trail. Kill revenants to follow those trails: each slain spirit fades and points in the right direction and will be marked on your map with a red arrow.
You can also stumble across the bloody grave by accident, but every revenant you kill contributes to the pile the demon feeds on. The fight is difficult because the demon hits hard. Use the Ninja style for increased mobility, stamina-efficient combat and Ninjutsu ranged attacks, and exploit Ninja bonus damage from attacking from behind.
