BLACKLIGHT VIRUS (DX-1118 C) Development After much experimentation on the flesh of an

ancient aberration, a group of alchemists managed

to synthesize a new virus strain which they named

'Blacklight'. Publicly, they were claiming it would

cure global diseases. However the real goal was to

engineer a virus that could copy and combine

genetic traits to re-write living creatures. An

aberration of sorts that could be weaponised, all

while connected to a hive mind.

Testing The alchemists were testing the virus on animals, noting

that a large portion of the virus’ variants had deadly effects on the test subjects. Countless animals were infected

with this variant and in a large number of cases, subjects showed dramatic increases in metabolic rate, strength, and

reaction times, as well as being a part of the hive mind network. However, due to the rapid changes caused by the

virus, the infected individuals usually do not survive the transformations as they once were in life, often dying or

becoming grotesque aberrant versions of their former selves.

Infection The virus is highly contagious and can infect organisms through a multitude of means, including physical contact,

exposure, bodily fluid contact, or direct administration. (See Template: Blacklight Aberrant)

Physical Contact: If a non-infected creature is bitten or scratched by an infected creature, or a Hunter, the virus can

spread directly to the victim resulting in their infection.

Exposure: Coming into contact with an infected water source via ingestion, or proximity to a Hive can result in the

infectious agents infecting nearby creatures.

Bodily Fluid Contact: Infectious bodily fluids and materials are capable of transmitting infection through open

wounds.

Direct Administration: As intended, the virus can be spread via direct administration.

Bonding In a mere 1% of all known cases of infection something incredible and rare occurs. In the event of one of these

occurrences, the genetic rewrite provoked by the Blacklight virus causes the body to metabolise and bond with the

virus on a cellular level. This results in an evolved viral-hybrid species with phenomenal abilities, completely

disconnected from the hive and eventually becoming a free willed deadly shapeshifting being of nearly limitless

potential, power and destruction. They can fashion portions of their bodies into weapons and cause mass

devastation to the environment with their incredible physical strength and durability. Newly enhanced musculature

and strengthened epidermis and bodily tissue increases their strength, speed, reflexes, and agility by shifting their

biomass to their limbs, allowing them to break the boundaries of human sprinting and jumping/climbing ability to

perform amazing feats. The Blacklight Mutator represents the result of this aforementioned 1%.

Blacklight Biomass Blacklight Biomass encompasses the following five features: Biomass Defence, Consume, Infected Thermal Vision,

Magic Rejection and Unarmoured Movement.

1: Biomass Defence Due to the bulk of your internal biomass acting as an absorption layer, your Armour Class equals 10 + your Dexterity

modifier + your Constitution modifier. You can use a shield and still gain this benefit.

2: Consume Consuming is the process by which you absorb the biomass and DNA or essence of other entities, copying and

assimilating it into your own in order to gain the entity's genetic memories and physical presence. After consuming,

the left over body is an unidentifiable mess.

As a bonus action upon dealing the killing blow to a creature, or as an action otherwise, you can consume a creature

as long as it is within 5ft and is either dead or on 0 hit points. Upon doing so, the following events happen:

Heal: Upon consuming, you can choose to metabolize part of the creature’s biomass and regain hit points

equal to one of the creature’s Hit Die + the creature’s level (or number of Hit Die). Once you use this

feature, you must finish a short or long rest before you can use it again.

Access memories: You receive random images and memories that represent part of the creature’s life

immediately after consuming it. Only works if the target was a humanoid with 3 or more intelligence.

Assume Form: Upon first consuming a corpse and accessing its memories, you can polymorph into the

creature as a part of the same action if it was a medium humanoid. At any time before consuming another

corpse, you can use your action to polymorph into the same creature, or back into your true form. The

change is only visual, your statistics are the same in each form. Your appearance is identical to the consumed

creature, however social interactions with others that the creature knew in life will require a CHA check to

avoid indicating that you are acting out of character. You revert to your true form if you die.

3: Infected Thermal Vision You have the natural ability to see the heat signatures of all living and/or infected creatures within 60ft. As an action,

you can adjust your vision to see such targets. Until the end of your next turn, you have the equivalent of darkvision

and you see the locations of any living and/or infected creatures within 60 feet of you. This allows you to discern the

exact location of targets who are invisible or behind any form of obscurement except Total Cover. You also know

whether each creature is infected or not.

You can use this feature a number of times equal to 1 + your Constitution modifier. When you finish a long rest, you

regain all expended uses.

4: Magic Item Rejection While attempting to use magic items, your biomass contorts and reacts wildly as if trying to protect itself and reject

the item. Whenever you attempt to use a magic weapon, magic armour or any form of magical wondrous item your

body twists and bends out of shape wildly, giving you disadvantage on all attack rolls, ability checks and saving

throws until it is no longer worn or wielded.

5: Unarmoured Movement Starting at 2nd level, your biomass increases the strength and speed of your legs. Your speed increases by 10 feet

while you are not wearing armour or wielding a shield. This bonus increases when you reach certain blacklight levels,

as shown in the blacklight table.

At 9th level, you gain the ability to move along vertical surfaces on your turn without falling during the move.

Mutate Weapon At 1st level you can select your first weapon mutation from the Bonus Mutations list. Your choices are Claws, Blade,

Hammerfist or Whipfist. You may form your selected weapon for free during your move or action just as any other

character can draw or sheath a weapon. In order to change the form of your weapon more than once per round will

require the use of your action.

Biomass Mutations Starting at 2nd level, your biomass allows you to harness the versatility of biomass mutation. Your access to this

ability is represented by a number of mutation points. Your Blacklight level determines the number of points you

have, as shown in the Mutation Points column of the Blacklight table. You can spend these points to fuel various

mutation features. You start knowing three such features of your choice that you meet the prerequisites for.

Whenever you gain the Bonus Mutation class feature, you may select a new mutation.

The maximum number of mutation points you can spend on a single mutation is equal to your proficiency bonus.

When you spend a mutation point, it is unavailable until you finish a short or long rest, at the end of which you

regenerate all of your expended biomass back into yourself.

Some of your mutation features require your target to make a saving throw to resist the feature’s effects. The saving

throw DC is calculated as follows:

Mutation save DC = 8 + your proficiency bonus + your Constitution modifier

Danger Sense At 2nd level, you gain an uncanny sense of when things nearby aren’t as they should be, giving you an edge when

you dodge away from danger.

You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this

benefit, you can’t be blinded, deafened, or incapacitated.

Absorb Shock Beginning at 3rd level, you can use your reaction when you fall to reduce any falling damage you take by an amount

equal to five times your blacklight level.

Ability Score Improvement When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your

choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score

above 20 using this feature.

Extra Attack Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Empowered Strikes Starting at 6th level, your natural attacks create their own supernatural signature and count as magical for the

purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Apex Predator At 20th level, you become an apex predator and your body reaches the pinnacle of genetic mutation. Your Strength

and Constitution scores increase by 4. Your maximum for those scores is now 24.

Bonus Mutation List Weapon Mutations Weapon mutations allow your biomass to create weapon-like forms in the place or

your arms. You may only have 1 type of weapon mutation active at any time.

Mutate Claws Once learned, your biomass allows you to mutate and produce claws. You gain the

following benefits:

• You can roll a d4 for your claw damage. This die increases 1d6 at 5th level, 1d8 at

11th level and 1d10 at 17th level.

• Special: When you use the Attack action with your claws on your turn, you can make

one additional claw attack as a bonus action.

Advanced Claw Mutations

Rend – (Prerequisites: Claws) Immediately after you take the Attack action on your turn, you can spend 1 mutation point to make two

claw attacks as a bonus action.

Ground Spike – (Prerequisites: Claws) As an action you can spend 2 mutation points to channel your biomass into the ground and make it erupt

under a targeted creature within 30ft. The eruption of spikes deals 2d8 piercing damage to your target and

all other creatures within 5ft. Targets take half damage on a successful Dexterity save. For each additional

mutation point you spend, increase the range by 10ft and the damage by 1d8.

Ground Spike Graveyard – (Prerequisites: Claws) The biomass from your Claws is channelled into the ground and erupts all around you. As an action you can

spend 2 mutation points to make your claws erupt in a 5ft radius around you. All affected targets take 2d8+2

piercing damage, or half on a successful Dexterity save. Enemies that fail the save are also knocked prone.

Each additional mutation point you spend increases the radius by 5ft and the damage by 1d8+1.

Mutate Blade Once learned, your biomass allows you to mutate and produce a heavy blade.

You gain the following benefits:

• You can roll 2d6 for your blade damage.

• Special: On your turn, when you score a critical hit with this weapon or reduce

a creature to 0 hit points, you can make one melee weapon attack as a bonus

action.

Advanced Blade Mutations

Air Slice – (Prerequisites: Blade) As an action for 1 mutation point you can perform an aerial drop attack. Jumping from a height above your

target, you transfer the energy of your fall into extra attack damage. Upon landing you automatically land on

your feet and take any applicable falling damage yourself. In addition, you make an attack roll with

Advantage against your target and for every 5ft you fall, your attack deals an extra 1d4 points of damage.

Blade Frenzy – (Prerequisites: Blade) When you take the Dash action, you can spend 2 or more mutation points to perform a Blade Frenzy. During

your Dash action, you can make one melee weapon attack plus an additional melee weapon attack for every

two mutation points spent at the beginning of your Dash action. These attacks can be on the same target or

different targets, but you must move at least 5ft between each attack.

Vorpal Blade – (Prerequisites: Blade, Level 3) Your blade’s ferocity increases and its edges sharpen. As a bonus action on your turn you can spend 1

mutation points to increase the critical hit range of your blade to 19-20 for 1 minute.

For 1 additional points you can roll an extra d6 when determining the extra damage for critical hits.

For 2 additional points you can roll two extra d6 when determining the extra damage for critical hits.

For 3 additional points you can roll three extra d6 when determining the extra damage for critical hits

and the critical hit range becomes 18-20.

For 5 additional points you can roll three extra d6 when determining the extra damage for critical hits

and the critical hit range becomes 18-20. In addition, a roll of 20 on the attack roll cuts off one of the

creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this

effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the DM

decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead

takes an extra 6d8 slashing damage from the hit.

Mutate Hammerfist Once learned, your biomass allows you to mutate and produce a heavy hammer-like

mass. You gain the following benefits:

• You can roll a d10 for your hammerfist damage.

• Special: When you roll a 1 or 2 on the damage die for an attack you make with your

hammerfist, you can reroll the die and must use the new roll, even if the new roll is a 1

or a 2.

Advanced Hammerfist Mutations

Blunt Force – (Prerequisites: Hammerfist) As an action on your turn for 1 mutation point you can begin charging extra mass into your hammerfist. On

your next attack within 1 minute you release your charge and swing. If you hit your target, roll damage as

normal and multiply the total result by 2, also knocking the target back 10ft.

Having your hammerfist charged in this manner requires focus. If you take damage while charged you must

make a Constitution save with a DC of 5 + the damage dealt or lose the charge.

Power Slam – (Prerequisites: Hammerfist) The biomass from your Hammerfist is slammed into the ground and erupts the ground around you. As an

action you can spend 2 mutation points to make your hammerfist deal normal weapon damage in a 10ft

radius around you. All affected targets take normal weapon damage, or half on a successful Dexterity save.

Enemies that fail the save are also knocked prone. The ground within a 10ft radius also becomes difficult

terrain as it shatters. Each additional mutation point spent increases the radius of difficult terrain created by

5ft.

Critical Pain – (Prerequisites: Hammerfist, Level 5) As an action, you can spend 2 mutation points to violently launch the biomass of your hammerfist towards a

target within 60ft. The target takes 2d6 + 10 Bludgeoning damage, or half on a successful Dexterity save.

Each additional mutation point you spend increases the damage by 1d6 + 5.

Mutate Whipfist Once learned, your biomass allows you to mutate and produce an extendable

whipfist. You gain the following benefits:

• You can roll a d4 for your claw damage. This die increases 1d6 at 5th level, 1d8 at

11th level and 1d10 at 17th level.

• Special: This weapon it has a melee attack range of 30ft.

Advanced Whipfist Mutations

Whiplash – (Prerequisites: Whipfist) You can spend 2 mutation points as a bonus action to whip, shove and pull a creature to unbalance it. A

creature that you can see that is within 30 feet of you must make a Dexterity saving throw. On a failed save,

the creature takes 3d10 piercing damage, plus an extra 1d10 piercing damage for each additional mutation

point you spend, and you can either knock it prone or pull it up to 25 feet closer to you. On a successful save,

the creature takes half as much damage, and you don’t pull it or knock it prone.

Street Sweeper – (Prerequisites: Whipfist) The street sweeper ability helps in dismembering multiple foes in front of you with a 90-degree swath. As an

action you can spend 2 mutation points to sweep your whipfist out in front of you dealing 3d6 piercing

damage to all targets within a 15ft cone, or for half damage if they succeed on a Dexterity save. For every

additional mutation point you spend, increase the range by 5ft and the damage by 1d6.

Tendril Barrage – (Prerequisites: Whipfist) As an action you can spend 2 mutation points to shoot tendrils of biomass out in every direction. Every

creature within a 30ft radius takes 2d4+2 points of piercing damage, or half on a successful dexterity save.

For each additional mutation point you spend the damage increases by 1d4+1. These tendrils penetrate

everything short of total cover.

General Mutations

Biomass Armour – (Prerequisites: None) As a bonus action for spending 1 mutation point you can encase your body in solidified biomass, granting

you resistance to bludgeoning, piercing, and slashing damage. This armour lasts for a number of rounds

equal to your constitution modifier. While encased in armour, you lose your unarmoured movement speed

bonus.

Genetic Regeneration – (Prerequisites: Level 17) Over the course of 1 minute, you spend 6 mutation points and your biomass starts pulsating, which

stimulates your natural healing ability. You regain 4d8 + 15 hit points and any severed body parts (fingers,

legs, and so on), if any, are completely regrown after 2 minutes. If you have the severed part and hold it to

the stump, it causes the limb to instantly knit back onto the stump.

Glide – (Prerequisites: Level 5)

The glide ability is believed to be achieved via the lightening of the Blacklight’s cells. This is caused by

shedding biomass, leaving a trail of mist streaming from the limbs. If you run at least 10ft and spend 2

mutation points, you can jump up 10ft and glide for 60ft until the end of your turn. At the end of your turn

you fall if you are still aloft. If you start your glide from a height, your glide distance increases by 10ft for

every 10ft you are off the ground. While gliding, any actions will cancel the glide and cause you to drop from

your current position. While gliding you can only maintain your current height or descend; you can never

gain height.

Greater Consumption – (Prerequisites: Level 3) When you consume a creature, you can spend 1 mutation point to end one disease that afflicts you, or one

condition from the following choices: blinded, deafened, paralysed, or poisoned.

Additionally, from level 9 when you consume a creature, you can spend 3 mutation points and end any one

of the following effects: The ‘charmed’ condition, one curse (including attunement to a cursed magic item),

any reduction to one of your ability scores, or one effect that is reducing your hit point maximum.

Mutate Shield – (Prerequisites: None) As a reaction when you are hit by any form of targeted attack, you can spend 1 mutation point to shift your

biomass into a shield and absorb damage. The shield can absorb damage equal 1d10 + your Constitution

modifier + your Blacklight level. Any excess damage beyond the shields limit is taken as normal.

Muscle Mass – (Prerequisites: None) As a bonus action you can spend 2 mutation points to significantly increase your muscle mass for 1 minute.

During this time you have advantage on Strength checks and saving throws, and when you make a melee

weapon attack using Strength, you gain a +2 bonus to

the damage roll.

Additionally, as an action during the duration, you can

pick up and throw an object. The total weight of the

object thrown can be up to your unencumbered

weight load. The object has a base range of 20 feet

and a maximum range of 60 feet. Your attack bonus

for all projectiles thrown is your proficiency bonus +

your Strength modifier. The damage of any projectile

you throw is shown on the table above + your

Strength modifier.

Pounce – (Prerequisites: None) You can spend 1 mutation point to take the Disengage or Dash action as a bonus action on your turn, and

your jump distance is doubled for the turn.

Primal Reflexes – (Prerequisites: None) When a creature misses you with a melee attack, you can use your reaction and spend one mutation point

to make a melee weapon attack against the creature at lightning speed.

Trample – (Prerequisites: Biomass Armour) When you take the Dash action, you can spend 1 mutation point to briefly encase your body in your biomass

armour (see Mutate Armour) and potentially trample all creatures in your path. As you move through

enemies (no larger than large) they must make a Strength save. If they fail, you knock them prone and keep

running. When an enemy succeeds their save you are prevented from moving further. At the end of your

turn, your armour gets assimilated.

Pack Leader – (Prerequisites: Level 11) The Pack Leader ability allows you to mutate the corpses of nearby creatures. Biomass tendrils extend from

you and into their bodies, pumping them with biomass, and using their genetic material to spawn brawlers.

As an action, you can spend 4 mutation points to transform any two medium sized creatures that have died

or are on 0 hit points. The biomass of each corpse mutates and contorts, changing from what they once

were, into the foul alien-like monstrosities known as Brawlers.

On each of your turns, you can use a bonus action to mentally command any brawlers you made with this

mutation if the creatures are within 60 feet of you (if you control multiple creatures, you can command any

or all of them at the same time, issuing the same command to each one). You decide what action the

creatures will take and where they will move during their next turn, or you can issue a general command,

such as to guard a particular chamber or corridor. If you issue no commands, the creatures only defend

themselves against hostile creatures. Once given an order, the creatures continues to follow it until its task is

complete. The creatures are under your

control for 1 minute, after which they stop

obeying any commands and self-destruct. The

explosion from each brawler has a 5ft radius

and deals 3d8 + 9 piercing damage, or half as

much with a successful Dexterity save, as

shrapnel from their corpses explode outward.

For every additional mutation point spent, you

can create 1 additional brawler, however each

brawler must come from its own corpse.
