Dark Knight Job Guide for FFXIV — Endwalker 6.4

Dark Knight is a greatsword-swinging tank job with a focus on resource management, burst damage, and proper application of frequent, short-duration defensive cooldowns.

Offensively, Dark Knight gameplay involves building and spending both Mana and Blood while managing a suite of high-value offensive cooldowns. A skilled Dark Knight player can plan ahead to combine their resource dumps for party buffs to bring out unparalleled burst damage from the tank role.

On the defensive side, Dark Knight's strengths are flexibility and support. While The Blackest Night alone doesn't match the strength of the other tanks' new short-cooldown mitigation skills in Endwalker, it can be used nearly twice as often, and Oblation is an entirely new tool for Dark Knight players to throw into the mix for themselves or for other party members. Dark Mind also provides high value against the very frequent magic damage encountered in trials and raids, with a shorter cooldown than any comparable skill.

This flexibility, along with its stylish aesthetic, make Dark Knight a popular pick both for casual play and hardcore progression.

To unlock Dark Knight, you must reach at least level 50 on any Disciple of War or Magic and finish the final story quest of A Realm Reborn, "Before the Dawn." Upon entering Ishgard, accept the quest "Our End" from an NPC called "Ishgardian Citizen" in The Pillars (X: 13.2, Y: 8.8) to start the Dark Knight job questline.

Dark Knight's job gauge is split into two major parts; the sword-shaped Blood Gauge, and the stylized helm of the Darkside Gauge beneath it.

At lower levels, the Blood Gauge consists only of the small icon to the left, which indicates whether Grit is currently active. On reaching level 62 and unlocking the Blackblood trait, the gauge expands to display how much Blood you have accumulated. Blood is gained through combo GCDs Souleater and Stalwart Soul, and by all GCD actions while Blood Weapon is active. Blood can be spent on Bloodspiller for single-target damage, Quietus for AoE, and on Living Shadow whenever it is available.

The Darkside Gauge shows the remaining duration of your Darkside buff, which is gained by using Flood of Darkness and Edge of Darkness or their upgraded forms Flood of Shadow and Edge of Shadow. Using up the entire shield granted by The Blackest Night causes the small, sword-shaped element to light up to indicate a free usage of your next Darkside generator. The final component of the gauge is a red version of the main Darkside Gauge, which appears when Living Shadow is summoned and tracks the remaining duration.

The pious Ishgardian clergy guide the flock, and the devout knights protect the weak. Yet even the holiest of men succumb to the darkest of temptations.

None dare to administer justice to these sacrosanct elite residing outside the reach of the law. Who, then, defends the feeble from the transgressions of those meant to guide and protect them?

A valiant few take up arms to defend the downtrodden, and not even the holy priests and knights can escape their judgment. Pariahs in their own land, they are known by many as “Dark Knights.”
