The Dark Slayer is a warrior of intense focus, wielding a unique mix of martial prowess intertwined with magical ability. They pride themselves on speed and precision, cutting down their foes in a blur of lights and slashes as they blink about on the battlefield.

Focus

Beginning when you choose this archetype at 3rd level, you generate magical energy that is tied to your concentration in battle. This energy is represented by a number of focus points equal to your Wisdom modifier (minimum of 0) + your proficiency bonus. Having these focus points grant you special bonuses while in focused concentration and you can expend it to power special techniques called focus strikes. You regain all expended focus points when you finish a short or long rest.

Charge Strike

Your focus points can be used to fuel certain abilities. At 3rd
level, you learn the following focus strikes.

Charged Strike. When you hit a target with an unarmed
strike, you can expend 1 focus point to deal an additional 1d6
force damage. If you are in focused concentration, the extra
force damage becomes 1d8 instead.

This focus strike has additional effects when you hit with
your unarmed strike depending on the number of additional
focus points expended. When you spend 2 focus points, the
target must make a Strength saving throw, or be pushed 10
feet away from you or be lifted 10 feet of the ground (your
choice). With 3 focus points, the target is also knocked prone
on a failed save. If the target is a Huge or larger creature, it
automatically succeeds on the save.

Focus strikes

At 3rd level, you automatically learn three
focus strikes, which are special techniques that are powered
by your focus points. You learn additional focus strikes when
you reach 7th, 10th, and 15th level in this class.
You can only use a focus strike once per attack.
Saving throws. Some focus strikes may require your target
to make a saving throw to resist its effects. The saving throw
DC is calculated as follows:

Focus save DC = 8 + your proficiency bonus + your Wisdom
modifier

Focused Concentration

As a bonus action, you can expend 1 focus point to enter a state of hyper awareness and you
begin concentrating, as if concentrating on a spell. This state
lasts for 1 minute, and it ends early if your concentration is
broken or if you end your turn with 0 focus points.
While in this state, you deal extra force damage the first
time you hit a target with an attack on a turn. The extra force
damage is equal to 1 for every 2 focus points you have.
You can also regain expended focus points or lose focus
points while in this state. You regain 1 expended focus point if
you take the Attack action and at least half of your attacks hit
targets hostile to you (rounded up), if you land a critical hit
against a creature hostile to you, or if you reduce a creature
hostile to you to 0 hit points with an attack. Conversely, you
lose 1 focus point if you roll a 1 on the d20 when you make an
attack roll or if you lose concentration as a result of taking
damage.
You can gain or lose

Judgement Cut

As a bonus action immediately after taking
the attack action, you can spend 2 focus points to make rapid
slashes that travel to a point you can see within 15 feet of you.
Each creature within 5 feet of the point must make a Dexterity
saving throw, taking 2d6 slashing damage on a failed save, or
half as much on a successful one. This damage becomes 2d8 if
you are in focused concentration.
You must be wielding a melee weapon that deals slashing
damage in order to use this focus strike.

Trick

As a bonus action, you can expend 1 focus point to
teleport to any unoccupied space you can see within 10 feet of
you. This increases to 15 feet if you are in focused
concentration.

Mirage Blades

Also at 3rd level, you can conjure spectral blades that fly
towards your enemies. You gain a new attack option that you
can use with the Attack action. This special attack is a ranged
spell attack with a range of 30 feet. You are proficient with it,
and you add your Wisdom modifier to its attack and damage
rolls. Its damage is force, and its damage die is a d6.
This special attack can be used for any of the attacks you
make as part of the Attack action.

Additional Focus Strikes

Also at 7th level, you learn two additional focus strikes, which you can choose from the following options.

Focused Blade. When you make an attack with a mirage
blade, you can expend 1 focus point to increase its range to 60
feet, and deal an additional 1d6 force damage on a hit (for a
total of 2d6 force damage).

Lunar Phase. When you make an unarmed strike, you can
expend 2 focus points to lunge forward 10 feet toward the
target with a vicious spin. This movement does not provoke
opportunity attacks and deals an extra 1d6 force damage on a
hit. If you are in focused concentration and the attack hits, the
target must make a Strength saving throw or be knocked
prone. If the target is Huge or larger, it automatically succeeds
on the save.
Rapid Slash. When you use Trick, or any similar spell or
ability (such as the misty step spell), to teleport to an
unoccupied space within 5 feet of a target you can see, you
can use your reaction expend 1 additional focus point to make
one melee weapon attack against that target.
You must be wielding a melee weapon that does not have
the two-handed or heavy property in order to use this focus
strike.
Stinger. As one of your attacks when you take the Attack
action, you can spend 2 focus points and lunge forward in a
straight line up to 15 feet towards a target. On a hit, you deal
an additional 1d6 force damage. If you are in focused
concentration, you deal an additional 2 force damage for
every 5 feet of distance you traveled before making the attack.
You must be wielding a melee weapon that deals slashing or
piercing damage in order to use this focus strike.

Focused Blade

When you make an attack with a mirage blade, you can expend 1 focus point to increase its range to 60
feet, and deal an additional 1d6 force damage on a hit (for a total of 2d6 force damage).

Lunar Phase

When you make an unarmed strike, you can
expend 2 focus points to lunge forward 10 feet toward the
target with a vicious spin. This movement does not provoke
opportunity attacks and deals an extra 1d6 force damage on a
hit. If you are in focused concentration and the attack hits, the
target must make a Strength saving throw or be knocked
prone. If the target is Huge or larger, it automatically succeeds
on the save.

Rapid Slash

When you use Trick, or any similar spell or
ability (such as the misty step spell), to teleport to an
unoccupied space within 5 feet of a target you can see, you
can use your reaction expend 1 additional focus point to make
one melee weapon attack against that target.
You must be wielding a melee weapon that does not have
the two-handed or heavy property in order to use this focus
strike.

Stinger

As one of your attacks when you take the Attack
action, you can spend 2 focus points and lunge forward in a
straight line up to 15 feet towards a target. On a hit, you deal
an additional 1d6 force damage. If you are in focused
concentration, you deal an additional 2 force damage for
every 5 feet of distance you traveled before making the attack.
You must be wielding a melee weapon that deals slashing or
piercing damage in order to use this focus strike

Additional Focus Strikes

At 10th level, you learn two additional focus strikes. Your
choice can be from any of the options you didn't take at 7th
level or you can choose from the following options.
You can also replace one focus strike that you took from 7th
level and replace it with one you didn't take at 7th level or
with another from the following options.

Kick 13

As a bonus action immediately after taking the
Attack action and using unarmed strikes for your attacks, you
can expend 3 focus points and make one additional unarmed
strike. If you are in focused concentration, you make one more
additional unarmed strike as part of the same bonus action.

Overdrive

When you take the Attack action, you spend 3
focus points and replace one of your attacks with a wave of
energy you release from your weapon in a 15-foot straight line
that is 5 feet wide. Each creature within this line line must
make a Dexterity saving throw, taking 3d6 force damage on a
failed save. If you are in focused concentration, you can
replace two attacks instead of one.
This focus strike has additional effects depending on the
number of additional focus points expended. With 4 focus
points, each Large or smaller target who fails the save is
pushed 5 feet away from you and is knocked prone. With 5
focus points, the force damage becomes 3d8.
The weapon you are wielding must not have the twohanded
property in order to use this focus strike.

Spiral Blades

As a bonus action, you expend 3 focus points
and manifest several mirage blades that spin around you until
the start of your next turn. During this time, whenever a
creature starts its turn within 5 feet of you or enters that area
for the first time in a turn, it takes 1d6 force damage. If you are
in focused concentration, the force damage becomes 1d8.

Void Slash

When you take the Attack action, you can
expend 3 focus points and replace one of your attacks with a
wide strike that radiates energy in a 15-foot cone.
Each creature on the ground within that area must make a
Dexterity saving throw. A creature that failed the save takes
3d8 force damage plus your weapon damage, and is pulled 5
feet towards you. On a successful save, a target takes half as
much damage and isn't moved. If you are in focused
concentration, a target that failed the save is also knocked
prone.
The weapon you are wielding must not have the twohanded
property in order to use this focus strike.

Motivated Focus

Beginning at 15th level, whenever you roll a Dexterity or Wisdom saving throw while in focused concentration, you can use your reaction to expend at least 2 focus points to add half
the number of expended focus points to the save.

Doppelgänger

At 18th level, you can use an action while in focused
concentration to conjure a spectral clone of yourself in an
unoccupied space within 10 feet of you. The clone lasts for 1
minute, and ends early if your focused concentration ends, or
as a bonus action on your turn. The clone is illusory and
magical in nature.
In combat, it shares your initiative count, but it takes its
turn immediately after yours. It can move and use its reaction
on its own, but the only action it takes on its turn is the Dodge
action, unless you take a bonus action on your turn to
command it to take another action. That action can be the
Attack, Dash, Disengage, or Dodge. For its reaction, it can only
do an opportunity attack.
When it takes the Attack action, it makes two weapon
attacks with a spectral melee weapon that deals 1d8 force
damage, and uses your bonuses for its attack and damage
rolls. You can also command the clone can also use focus
strikes as part of its attacks (no additional action required),
expending your focus points when it does so.
You can summon your clone once, and must finish a long
rest in order to do so again.

Additional Focus Strikes

At 15th level, you learn two additional focus strikes. Your choice can be from any of the options you didn't take at 7th or 10th level, or you can choose from the following options. You can also replace one focus strike that you took from 7th or 10th level, and replace it with one you didn't take at those levels or with another from the following options.

Heavy Rain Blades

When you hit a creature with your
Mirage Blade attack, you can expend 3 focus points to deal an
additional 2d4 force damage, as several blades follow suit. If
you are in focused concentration, you deal 2d6 force damage
instead. The target must then make a Strength saving throw,
or become restrained until the start of your next turn. If the
target is restrained while in midair, it remains suspended
there until the start of your next turn.

Hell on Earth

You slam your fist into the ground and
release a powerful burst of energy. As an action while in
focused concentration, you expend 5 focus points to cast the
destructive wave spell. When you cast the spell in this way,
you deal force damage instead of the spell's two damage
types.
You can use this focus strike once, and must finish a long
rest in order to do so again.

Judgement Cut End.

You slash at blinding speeds, as if
appearing in several places at once. As an action while in
focused concentration, you expend 5 focus points to cast the
steel wind strike spell. When you cast the spell in this way, you
make melee weapon attacks instead of a melee spell attacks.
You must be wielding a melee weapon that deals slashing
damage in order to use this focus strike. You can use this focus
strike once, and must finish a long rest in order to do so again.

Trick Dodge

Your focus allows you to teleport out of harm's
way. When you are targeted by an attack, you can use your
reaction to expend 4 focus points and teleport to any
unoccupied space you can see within 15 feet of you.
If you are in focused concentration, you can choose to
forego expending focus points and instead make a Wisdom
(Insight) check against the attacking creature's attack roll. On
a successful check, you spend no focus points and instead
gain 1 focus point, as you teleport away at the very last
moment. On a failed check, the teleport fails and the attack
automatically hits you.
Alternatively, when you are subjected to an effect that
allows you to make a Dexterity saving throw to take only half
damage, you can use your reaction to expend 3 focus points
and instead take no damage if you succeed on the saving
throw, and only half damage if you fail. On a success or fail,
you teleport to any unoccupied space you can see within 15
feet of you.
