The Onyx Lord can be found deep within the Sealed Tunnel in Altus Plateau. The path to the end of the tunnel is obscured by several Illusory Walls that you will need to attack to reveal the way.

When to Fight Onyx Lord

Onyx Lord is one of the easier bosses to fight in this region, as it is easily staggered by two-handed strong or jumping attacks, making its moves interruptible. Tackle this boss first before moving on to the central region of Leyndell, Royal Capital.

Break Onyx Lord's Poise

Onyx Lord has fairly low poise, so it's possible to interrupt its attacks using two-handed strong attacks and jump attacks or simply by using large weapons.

Make Good Use of Your Shield

Counterattack With Guard Counter

Onyx Lord moves relatively slowly so it will be quite easy to perform Guard Counters against this boss. This is a good way to get Onyx Lord to stagger, making it open to critical attacks.
How to Guard Counter

Use Barricade Shield

Barricade Shield is a good shield skill to use, as it reduces stamina lost when blocking, making it much easier to use Guard Counters on this boss.
Barricade Shield Weapon Skill and How to Use

Move Counterclockwise

If you're not a shield-focused build, you can still fight Onyx Lord effectively by moving and dodging counterclockwise and attacking his back.
