The Time Keeper

The Time Keeper is the third boss in Dead Cells. She was added in the Brutal update. The Time Keeper is found in the Clock Room which can be reached from The Clock Tower or The Forgotten Sepulchre.

As of the Baguette Update alpha, attack damage on a single hit is soft-capped at 3% of the Time Keeper's maximum health.

First Phase

 * The Time Keeper performs one slash with her sword.
 * The Time Keeper throws one shuriken forward.
 * The Time Keeper throws a hook that, if hit by, pulls the player to the Time Keeper and roots them in place, followed by a powerful blow.
 * The Time Keeper teleports a short distance away from the player (often used before shurikens, hook or dash)

After reaching around 70% health, the Time Keeper conjures a shield of spinning shurikens and pushes the player outward, after which the second phase begins.

Second Phase

 * The Time Keeper performs a two-hit combo with her sword.
 * The Time Keeper throws three shurikens in a quick succession.
 * The Time Keeper performs a dash attack through the entire room.
 * The Time Keeper throws a hook that, if hit by, pulls the player to the Time Keeper and roots them in place, followed by a powerful blow.
 * The Time Keeper teleports a short distance away from the player (often used before shurikens, hook or dash)

After reaching around 35% health, the Time Keeper teleports away and says "Let's finish this" in a cutscene, before conjuring another circle of shurikens and entering the third phase.

Third Phase

 * The Time Keeper performs a three-hit combo with her sword.
 * The Time Keeper throws five shurikens in a quick succession.
 * The Time Keeper performs two dash attacks one after another.
 * The Time Keeper throws a hook that, if hit by, pulls the player to the Time Keeper and roots them in place, followed by a powerful blow.
 * The Time Keeper teleports a short distance away from the player (often used before shurikens, hook or dash)
 * Swords fall on the player's location and randomly around the room.

Attacks

 * Understanding the attack pattern is the first step to beating The Time Keeper
 * All of her attacks can be roll-dodged, including the fallen swords.
 * She is susceptible to all forms of crowd control, like freezes, slows and Bear Trap.
 * The blow following the hook-pull can be blocked or parried with a shield, despite the player being rooted in place.
 * Getting hit by the three-hit combo in the last phase can be deadly, because the hits stun the player just long enough for her to land the next blow(s).

Weapons/Items

 * As she can be frozen, you can use this and hit her with a massive damage weapon, like Cursed Sword or Heavy Crossbow
 * Phaser and Assassin's Dagger is a good way to cause massive damage to The Time Keeper
 * Also, parrying most of Time Keeper's attacks is a good way to beat her, as seen in this video Shield build strategy

Trivia

 * Before the Baguette Update, the Time Keeper was known as 'The Assassin'
 * according to the transition loading screens added in the Baguette Update also, it appears that she requested the king of the island to build the Clock Tower, for unknown reasons
 * For the second and third phases to activate, it is necessary that the Time Keeper teleports away from the player first. Because of this, if the player manges to deal massive damage in a short amount of time, it is actually possible to end the fight before she enters the second and/or third phase
