Black Knight Sword


Greatsword Wielded by the Black Knights who wander the lands. Designed to face chaos demons.

Black Knights constantly faced foes larger than themselves, and this sword's unique attack greatly reduces enemy poise.

Skill: Perseverance
Raise sword in the name of the First Lord to temporarily boost poise. Damage reduced while activated.


  • Bonus damage to Demon enemies: 20%.


  • Treasure in the Demon Ruins area of Smouldering Lake. Found in a room behind an illusory wall with an axe-wielding Black Knight inside.
    • To reach the room start from the Demon Ruins bonfire and descend until you enter the room with the first enemy.
    • Take the stairs down into a hall with two more enemies and head right.
    • Enter the passage at the end of the hall and follow it straight all the way down until it turns left.
    • Strike the wall at the corner of this passage to reveal the room with the Black Knight and sword inside.



The Black Knight Sword is extremely powerful for builds who focus equally on Strength and Dexterity despite its somewhat mediocre stat scaling. These builds will find themselves doing more damage with this weapon than any other greatsword. Its downside is a much less versatile moveset compared to other options like the Claymore, which can function well even in close quarters due to its thrusting attacks. This, coupled with the fact that the Black Knight Sword is not infusable or buffable, makes it a less adaptable weapon.

The Damage stat dictates how much damage the weapon does. The Damage stats for a weapon are A / B / C / D / E:

Each weapon has one or more Physical damage types:

  • Standard
  • Strike
  • Slash
  • Thrust

Certain enemies are weak or strong against different damage types.
See the damage formula for further details.

Aux Effect:

The Aux Effect stat dictates how effective the weapon will be at causing the effect. The Aux Effect stats for a weapon are A / B / C:


Damage multiplier when performing a backstab or riposte. Value of 100 means no extra damage.

Spell Buff:

Damage multiplier applied to the base value of a Spell. This value scales depending on the primary stat of the Catalyst, i.e. a Catalyst with Intelligence scaling will have its Spell Buff rise as the player's Intelligence rises.

By default the value reflected in the infobox and the upgrades uses 60 Intelligence and/or Faith.

Stats Needed:

The Stats Needed determines how high various Stats must be in order to wield the weapon effectively. The stats required for a weapon are A / B / C / D:

Wielding a weapon without the required Strength and/or Dexterity will incur a penalty to the Physical damage of the weapon, while lower-than-required Intelligence and/or Faith will reduce the Magic/Fire/Lightning/Dark damage and Spell Buff.

Stat Bonuses:

The Stat Bonuses rating indicates the level of bonus damage you do with the weapon, based on the associated Stat. This rating can be S, A, B, C, D, or E (in order from most to least bonus for the associated skill). See Scaling for more information.

The Bonus Stats for a weapon are A/B/C/D:

Damage Reduction:

The Damage Reduction % of the weapon. It dictates how much damage the weapon mitigates while blocking. The Damage Reduction % stats for weapons are A / B / C / D / E :


Determines the amount of stamina expended to block an incoming attack. A higher stability also allows you to block stronger
attacks without breaking guard and reduces the amount of stamina depleted from blocking attacks.


The durability of the weapon.


The weight of the weapon. Note that carrying over 70% of your Equip Load will reduce the speed of your rolls, while going
over 100% will reduce your regular speed to walking and attempts to roll or backstep will leave you momentarily stunned.
