Starcraft Zerg Experiment

Standing on the brink of death, heavily wounded a female gnome crawls backwards to the side of a cliff, descending its face. She struggled down to the next cliff as she thought of her recent on hand creation she made to distract her persuers, a mechanical squirrel. It had so much life but now she has a gunshot wound in her side. Her skin now a purple hue, and a connection to the zerg. Being hunted like a dog she finally reaches the very edge of the cliff as her persuers are closing in on her. She revels at some thoughts then stands up and lets out a small maniacal laughter yelling out "YOU FOOLS SHOULDA KILLED ME FASTER NOW YE ARE DEAD" as multiple pods drop from the sky releasing zerg from them almost immediately pouncing, tearing, and melting down her persuers.

Rushing through a dungeon, a group of adventurers composing of a pyrotech, a marine, marauder, and ghost are about to reach the very end when they realise something. What happened to their last party member? Going back they realize that their friend had fallen prey to a trap killing him instantly. Saddened and about to go on a spector slowly rises from the body and greets them... Confused momentarily they ignore it and go on to the final room. With less then half of the stats that the spector once had he came crucial healing his allies and keeping them alive using his transparency as an advantage to hide and heal his allies.

A group of friends rendezvous on a hill overlooking a giant site. They realize that they are way over their heads when they see a giant compound full of tanks, goliaths, and multiple patrols guarding an entrance. They know that they can't go any farther and huddle together to come up with a plan and then out of no where it hits them. Wheres shank? Their infested terran friend? They stand up and look to their right and see a base being constructed surprised they wait a couple of hours and figure it out. Shank had instructed his drones to build him an army and is commanding it to a fine degree to make what they need to break the encampment. After unknown hours go by they have a mass amount of zerglings. Charging down the hill they easily over take the encampment and charge into the entrance. Easily destroying the dungeon the zerglings start to quiver. They look to each other and realize, the control of overlords are too far and they are going feral. Worried they were too late as the zerglings turn and start tearing the party apart.

What are the Experiments?

The experiments are the swarms way of figuring out what is best vs the protoss and the terran. They are typically for the testing and breeding areas of evolution and study. They are experiments that are held for figuring out what the potential of terran and or protoss that they infest and grant their psionic prowess to. They typically scout out certain individuals that have a high psionic presence before making a move and in a sense kidnapping, convincing, or persuading to become an exeriment for the swarm. In typical fashion all that serve the swarm must fear the swarm. All that serve the swarm are subject to consumption for the great overmind and higher power.

Mind of the Experiments

Most that become an experiment are always warry of the zerg themselves. They fear that one day that they will be the ones that will be consumed and they typically steer themselves away from the swarm and other zerg. They know that whatever they learn will evidentally become the swarms knowledge whether they like it or not. The experiments also know that they must keep a constant contact as well or something bad will happen (ask your DM about this) due to the fact that they either hold something against them or hold their life essence that forces them back every time.

How would they fit in society?

In a regular terran society they would be hunted down and studied to see what they zerg is and how they are able to control them to the extent that they can. In a protoss society they would be slaughtered on sight without anyone trying to see or study what they are. The Zerg are the natural enemy of the Protoss. If the PC is able to stay concealed they can most likely get through regular settlements and be unhindered but if not be prepared for multiple fights and persecution.

Using Abilities

Almost all of the Zerg Experiments abilities are used through psionic activations and commands. When using your abilities you will be using your body to create the ability that somehow shoots out or some other method. For example for energy blast you are able to channel energy into a point from your fingertips and release an amount of energy sending a blast towards your target tickling it with lightning damage.

Psionic Prowess

At first level, you have a psionic prowess that allows you to use your psionic points to enhance your bodily abilities, and psionic abilities. If you must make a target make saving throws or you use your abilities use the following. You slowly regain your psionic points by 1 point for every 10 minutes.

Saving Throw. = 8 + Intelligence Mod. + Proficiency Bonus.

Attack Modifier. = Intelligence Modifier + Proficiency Bonus.

Mend

As an action you are able to spend 2 Psionic Points and cause certain wounds to close and heal. In doing so, you heal a target up to 15ft away from you a number of dice equal to your mend table listed above. For every 2 Psionic points spent after the initial cost, roll the mend dice again all at once.

Energy Blast

You are able to harness your mental capabilities into a blast of energy that leaves your body and destroys your target. You are able to make a ranged attack against one target up to 45ft away from yourself. On hit the target takes 1d8 Lightning damage. To use this you must spend 2 psionic points. For every 2 energy spent past the initial cost increase the damage done by 1d8 to a maximum of 6 energy to be spent. Tha maximum increases to 12 energy at 7th level.

Crushing Grip

At 2nd level, Spending 5 Psionic points, as a action choose a creature within 30ft of yourself forcing it to make a constitution saving throw vs your Psionic prowess. On failure, the creature is stunned for 1d4 rounds. For every 5 points spend past the inital cost choose an additional creature to force a constitution save to a maximum of 15 Psionic points spent.

Experimental Mutations

At 3rd level you are able to choose a mutation that would change the way you approach things altogether. Choose between The Lord of the Body. Which focuses mainly on enhancing your own body and providing benefits for your allies. Or The Lord of the Brood. Which focuses mainly on building a temporary swarm of your own to do your bidding. But be wary, you will be subjecting yourself to interstellar war. You gain bonus features as well from these mutations at 6th, 10th, 14th, and 17th levels.

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.

Chain Reaction

At 5th level, you are able to channel your Energy blast in a more efficient way. You are now able to attack up to three other targets whenever you use your energy blast but they must be within 15ft of your original target. For each attack, another attack roll must be made.

Leaping Strike

At 7th level, as a action, you are able to leap at a target within 45ft reaching a max height of 20ft, you can choose to use this as a jump instead it is optional, but if you are targeting another creature make a ranged attack. On hit, you deal 2d6 piercing damage to your target. Spend 10 psionic points to do so. You may spend more points to increase the damage, the damage increases by 2d6 for every 5 extra psionic points spent past the initial 10 points to a maximum total spent of 20 psionic points.

Psionic Shift

At 9th level, you are able to dash forward in a straight line damaging all enemies in your path. To do so you must spend 15 psionic points. All creatures within a 30ft dash, 10ft wide, must make a Dexterity saving throw vs your Psionic Save DC. On fail they take 4d12 lightning damage. On pass they take half as much. You can increase the number of dies by 2d12 for every 15 additional psionic points spent to use this ability. This is used as an action.

Malignant Creep

At 11th level, you start to emit a passive creep from yourself that grows over the area wherever you go. This creep can be burned to get rid of, and will disappear if you are not within 30ft of the creep slowly over a 5 minute span. This creep slowly generates at a 5ft radius from yourself to a maximum of 30ft centered on you. All allies and yourself on the creep gain an additional 5ft movement speed, and one additional attack (not an action). All enemies that step on, or start their turn on this creep must make an Constitution saving throw. On fail their movement speed is reduced by 5ft (to a maximum of 15ft) and take 2d6 poison damage. This also disrupts any building that must be rooted if they are not rooted before hand. (For example if a building is planned to be built and the creep is there it cannot be built. But if the building is already built or already in progress of being built it is not disrupted. If a building tries to land on creep it cannot and will automatically stop its landing process.)

Fury

At 13th level, you gain a small tick for every time that you attack that increases the amount of attacks you are able to make. Whenever you make an attack with Energy blast, you can immediately use it again for free as an bonus action. If you do so two turns in a row you are able to do so again after the second time it is used. (Second bonus action to make 2 additional attacks with energy blast). These attacks are using the lowest form of energy blast but psionic points can be spent to increase the damage of the bonus attacks that you are making.

Kinetic blast

At 15th level, as a action you can release a deadly blast of manifested psionic energy dealing massive damage to your target. As an action you can spend 20 psionic points to target a creature or structure/construct within 60ft and make a ranged attack roll. On a hit you deal 6d20 Force damage.

Ability Efficiency

At 18th level, your mental capabilities increases and the amount of psionic points spent for your abilities refine the excess amount that is being spent. When using a ability that requires psionic points, reduce the amount spend by half rounded up.

Apocalypse

At 20th level, you are able to channel all of your psionic points and release them to make a large area of effect against all enemies within range. Spending all of your points (minimum of 30), you force all creatures within 45ft of yourself to make a Dexterity saving throw. On fail, all creatures take 20d6 Necrotic damage and are stunned for 1d4 + your Psionic attack modifier turns. On pass, they take half damage and are not stunned.

Lord of the Body

The Lord of the Body is typically the ones that help the growth and protect their allies. They are the ones that heal, and grant certain bonuses for their allies and allow the progression of their own depth go farther.

Mend Upgrade

Starting when you choose this mutation, your mend now gains a radius centered on your target. Whenever you heal a target (or yourself) you apply your mend to all creatures within 10ft of your target.

Psionic Reflex

At 6h level, you are able to channel your psionic prowess into allies within 30ft of you increasing the biomass within their mind temporarily. After spending 10 psionic points your target gains an additional action and 15ft bonus movement speed for 10 minutes.

Psionic Weapon

At 10th level, you are able to channel your psionic prowess into the weapons of your allies and your own. After spending 15 psionic points the targeted weapon up to 10ft away gains a psychic damage die of 2d10 in which lasts for 20 minutes.

Psionic Consumption

At 14th level, you are able to use your psionic prowess to consume a willing creatures thoughts or a target creatures thoughts. The target must make a intelligence saving throw or take 3d12 psionic damage and regain psionic points equal to damage dealt this way. On fail, the target takes half damage, and you still regain psionic points equal to the damage dealt. This can be used a number of times a day equal to your Intelligence modifier (minimum of one).

Ascension

Starting at 17th level, if you die you can choose to become a incorporeal entity on the ethereal plane at the spot you died in the material plane at the start of your next turn. This entity has the physical ability scores (Strength, Dexterity, Constitution) and abilities of a Ghost, but has your mental ability scores (Intelligence, Wisdom, Charimsa) and your Experiment class abilities.

When you take this form your current and maximum hit points becomes that of the ghost while you are in the form, if you have less than 50 psionic points, have 50 psionic points. While in this form you cannot rest to regain spent abilities. If you exhaust all Psi Points or the ghost is destroyed, you die as a normal creature would.

Lord of the Brood

The Lord of the Brood is one of the creators of the swarm. They are the forward operators that create the brood and allows the zerg to have an forward operating base allowing them to grow fast and allow their swarms to fastly expand. Typically queens are Lords of the Brood but thats a story for another day. All stats for creatures and buildings are listed at the end of the mutation.

Spawn Cocoon
