Splicers are the most common enemies in the first two installments of the BioShock series, and in the DLC of its third. Remnants of Rapture's human population, they are the result of ADAM use, which greatly increased during the violent conflict of the Rapture Civil War. In this war, and the chaotic days that followed, the Splicers murdered much of the sane population of the city. Due to excessive ADAM consumption, their bodies and minds have been deformed beyond repair (though some of their physical deformities can be attributed to war scars or Dr. J.S. Steinman's plastic surgery). They have become dependent on ADAM, both mentally and physically. Many still wear Masquerade Ball masks, perhaps, as Atlas suggested, out of shame at how ADAM has deformed their bodies.

Insanity of the Deep[edit]

Splicers used to be normal people, but now due to the abuse of the drug known as ADAM, they have gone completely insane. With many varieties of splicer, their deep mental instability is best shown in their combat, flailing wildly and attacking any person in sight just to get their next fix of ADAM.

Creating a Splicer[edit]

Put yourself into the mind of a person who's mind and body have been altered in the need for drugs. Take that desperation and cunning into mind. How are you going to get more, when will you get more, and who will you have to kill to get more? Your past doesn't matter anymore. you've killed your family and if not then they are long gone and will never return, but that doesn't matter. You have another hit of ADAM in your veins and it feels great. Now you just need another...

ADAM Armor[edit]

Due to the intense amount of ADAM within your body, your skin, meat, and bones are impowered and are more resistant. At first level, your Armor Class is your DEX modifier plus 10.

Atlas Brand Insomnia[edit]

The terrors of Rapture still haunt your dreams, but you've grown used to it. At second level, all actions that require a long rest can be don with a short rest. This only applies to you.

Splicer Archetype[edit]

At 3rd level, you chose a Splicer Archetype. Choose between Thuggish Splicer, Leadhead Splicer, Spider Splicer, Houdini Splicer, and Nitro Splicer, all detailed at the end of the class description. Your choice grants you features at 3rd level and again at 9th, 13th, and 17th.

Ability Score Increase[edit]

When you reach 4th level, and again at 8th, 10th, 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.

Cunning Deception[edit]

You have learned that people down here aren't the brightest, and will generally ignore a dead body... or what they think is one. At 5th level, as a reaction to a successful hit against you, you can pretend to have died and as a bonus action get up and continue to fight. For each full turn you pretend to be dead you must make a constitution save with a DC on 15.

At 11th level you improve on this skill making the save DC a 10 and causing all creatures within 15 feet to become stunned. Stunned creatures can remove the stun by making a successful constitutions save (which takes up one action).

Eye For Insanity[edit]

Your attacks have become more sporadic, for better and for worse. At 6th level, you can now achieve a critical hit from a 19, but you can also receive a critical fail from a 2.

At 14th level this increases again to natural 18s and higher being critical hits and natural 3s and lower being critical fails.

Sneak Attack[edit]

Once per turn, you can deal extra 1d8 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must be on a creature that cannot see you. As you gain levels, the amount of damage increases, as shown on the level table. The amount of the extra damage increases as you gain levels in this class, as shown in the Sneak Attack column.

Mindless Running[edit]

You learn how to run more efficiently. At 15th level, as a bonus action you can double your movement speed.

Violent Tendencies[edit]

At 18th level, you can use a bonus action to add 4d6 to an attack for the cost of one third level EVE slot.
