Black Blade

The burn lasts 2 seconds and removes 0.1% of the target’s current maximum HP plus 1 HP per tick, at intervals of about 0.1 seconds. This HP loss is separate from the impact’s damage and defenses. Each application creates an independent burn. The number of applications depends on actual hits; maximum-HP restriction is a separate effect.

Effects

A target actually struck by the effect has its maximum HP reduced by 10% for 15 seconds. Reapplying Black Blade refreshes its own restriction rather than repeatedly multiplying it. Current HP cannot exceed the reduced maximum. When the restriction ends, the maximum returns but this does not heal missing current HP. The direct hit and the short health-draining burn are separate.

Technical details

Health Points

The burn lasts 2 seconds and removes 0.1% of the target's current maximum HP plus 1 HP on each native tick. This is direct HP loss, separate from the impact's defense and elemental damage calculation. Each confirmed application creates an independent burn instance. The engine uses the supplied actual update deltas, checks for a due tick before advancing its clock and combines burns due on the same update before integer truncation. Supply confirmed effect applications, the affected target, its maximum HP and its HP-damage suppression state. This does not infer how many projectiles or weapon hits connect. Maximum-HP restriction is a separate effect.

In-game description

Power gleaned from the remembrance of Maliketh.

Caster creates an illusory black blade, then leaps forward to deliver a spinning slash that emits a wave of light.

This can be followed up with one additional attack.

This blade was once imbued with Destined Death. In addition to dealing damage, it reduces foes' maximum HP and continues to sap their current HP for a very short time.

Where to find

Maliketh's arena, then Roundtable Hold

Crumbling Farum Azula

Starting Site of Grace: Beside the Great Bridge

Before you go

Defeat Maliketh, the Black Blade.

Defeat Fire Giant and continue the story at the Forge of the Giants to reach Crumbling Farum Azula. The small section reached through the Four Belfries does not connect to this boss route.
Progress through Farum Azula and defeat Godskin Duo. Continue through the northern ruins and Dragon Temple Rooftop route until you reach the lift to Beside the Great Bridge grace.
From that grace, climb the stairs and turn uphill on the great bridge. The downhill side leads toward different loot. A Draconic Tree Sentinel guards the uphill approach; defeat it or get past it to the fog door.
Enter the arena and defeat Beast Clergyman and his second phase, Maliketh, the Black Blade. This victory changes Leyndell into the Ashen Capital, so collect any missable Royal Capital items before finishing the fight.
After the scene, activate Leyndell, Capital of Ash grace. You can return to Roundtable Hold now without defeating Gideon or the remaining main bosses.
Return to Enia and exchange Remembrance of the Black Blade for Black Blade, the incantation. Maliketh's Black Blade is the separate weapon choice.

Notes

Requires 46 Faith, uses two memory slots and costs 26 FP per cast. An immediate second cast gives the follow-up swing for another 26 FP, making both attacks 52 FP.
The conjured sword and its wave deal Holy damage and can both connect at close range. Damage follows the casting seal's Incantation Scaling, rather than the attack power of an equipped melee sword.
The first sword contact has attack power equal to 225% of Incantation Scaling and the wave 162%. The follow-up rises to 232% and 169%, respectively, before bonuses and enemy defenses.
The sword contributes 9 stance damage and the wave 4 when both connect. Firing from outside sword range gives up the sword contact.
Its effect temporarily reduces maximum HP by 10% for 15 seconds and leaves a brief percentage-based health drain. The reduced maximum is temporary, rather than permanent damage to an enemy's maximum health.
Repeated casts refresh that same effect rather than removing another 10% maximum HP each time. Some Realm of Shadow bosses resist the ongoing drain more strongly.
Holy and incantation damage bonuses improve the direct Holy hits. They do not multiply the percentage of maximum HP removed.
Godfrey Icon does not improve the spell because it cannot be charged. Shard of Alexander boosts weapon skills, rather than this incantation.
It is separate from Maliketh's Black Blade, the colossal sword. The shared remembrance offers one reward per exchange, and their attack scaling and debuff durations differ.
The sword and wave are both parts of this incantation. Raising an equipped sword’s upgrade level does not strengthen the cast, and repeating it does not permanently remove another tenth of the target’s maximum HP.
