Blacklight Mutation (5e Class)

Blacklight Mutant

The Virus

The Blacklight Virus is an evolutionary chimeric mutation-causing infectious agent that can reproduce only inside the living cells of other biological organisms. It is the result of numerous experimentation of an ancient aberration's flesh, created by an order of shadowy alchemists and wizards in order to attain immortality without the need or help of any dark power or eldritch being that would most likely enslave them for their own purposes. However, what came out instead is a virus that has a 99.99% mortality rate, capable of killing anything that it infects and possibly turning them into horrors as well.

But for the very few 0.01%, the infected gains extraordinary abilities and genetic prowess. These people can genetically alter themselves, allowing them to mutate their body into weapons and shields which allow them to crush their enemies. Congratulations, you are that 0.01%.

Origin

How did you obtain this virus? Were you subjected to it by the very order that has created it or were you just an unlucky passerby who just got infected by whatever horror the virus has created? How has this affected you that now you are a monster? Does your community know of your condition or do you act like a wolf hiding amongst the sheep? These are some of the things to consider when creating a Blacklight Mutant.

Blacklight Mutation

Starting at 1st Level, you have been infected by the Blacklight virus, but fortunately for you, you are the 0.01% and have now survived the infection. Unfortunately for you, the virus has now forever altered your genetic code, making your character part Aberration. While this may not exactly be detrimental to you in the short term, but sooner or later some people would come to find you with disgust and horror, possibly hunting you down for the purposes of ending your existence.

But in exchange, your body has mutated to be more tougher and resilient and has mutated to adapt better to your surroundings. Starting at Level 1, you now have resistance to Poison damage and have advantage in Poison and Disease saving throws. You also count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift and you can also breathe underwater naturally.

You can now also effectively eat or drink anything organic to fuel your biomass.

Biological Weapons

Starting at 1st Level, you are your own arsenal, allowing you to mutate your arms into Biological Weapons (Bioweapons) of your own choice. These weapons are considered normal weapons and can either use the character's Constitution, Strength or Dexterity (Finesse) modifier for attack and damage rolls with these weapons. You may only have one form active at all times, but can never be disarmed of your own Bioweapon. With a Bonus action, you can change your arm's shape in the following ways:

Mutate Claws

Damage: 1d6 Slashing
Properties: Finesse, Light, Special
Special: When you use the Attack action with your Claws on your turn, you can make one additional Claw attack as a bonus action.

Mutate Blade

Damage: 2d6 Slashing
Properties: Two-Handed, Heavy, Special
Special: On your turn, when you score a critical hit with the Blade, you automatically deal maximum damage.

Mutate Hammerfist

Damage: 1d10 Bludgeoning
Properties: Heavy, Special
Special: When you attack and hit a creature with your Hammerfists, you may choose to knock the creature back 10ft.

Mutate Whipfist

Damage: 1d4 Slashing
Properties: Finesse, Reach, Special
Special: The Whipfist has a melee weapon range of 30ft.

Mutate Shield

Properties: Special
Special: You can use your Reaction to summon the Mutate Shield when receiving an attack, giving you +2 AC for that attack. After being used in that reaction, you automatically mutate back to whatever weapon (if any) you had before the reaction.

In addition, the virus has mutated you in such a way that you are stronger than the average creature in Unarmed combat. You can roll a d6 in place of the normal damage of your unarmed strike and you can either use Strength or Constitution for the attack and damage rolls of your unarmed strikes. When you use the Attack action with an unarmed strike on your turn, you can make one unarmed strike as a bonus action

Mutated Defense

Starting at 1st Level, your body has mutated to be able to defend itself better, allowing it to take hits and blows most would find lethal. Your AC equals 10 + your Dexterity modifier + your Constitution modifier.

Consume

Starting at 2nd Level, you've learned how to use the biomass of others to fuel yours. When you reduce a creature to 0 hit points, or if the creature had died within the last 24 hours, you can choose to use your Reaction to Consume a creature. When you do, you gain temporary hit points equal to your Constitution modifier + half your level (minimum of 1). Upon consuming the creature, you can use a Bonus action to polymorph into the creature's form and clothing (if it has any), gain it's voice, and attain its memories from the last 24hrs. The change is only visual as your stats and attributes are the same in each form. Do note that you can only assume the form of the creature you most recently consumed and can only assume the form of your size or one size smaller than you. Consuming a creature also counts as eating or drinking as it fuels your biomass.

To pass off as the creature, you must pass a Charisma (Deception or Persuasion) check to act out as the creature and not arouse suspicion from the consumed entity's allies.

Biomass Mutation

You may now utilize your own biomass to fuel your abilities. Starting at 2nd Level, you now have access to Mutation Points. You have a number of Mutation Points equal to your Level. You regain all of them after a short/long rest. You can spend these points to perform the following actions.

While using the Hammerfist, you can spend 2 Mutation Point to begin charging extra mass into your Hammerfist. On your next attack within 1 minute you release your charge and swing.

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