Slivers

Slivers are unique species of creature that originally came from the card game Magic: the Gathering. They are a hivemind race with extreme evolutionary adaptability that spreads throughout the colony. Slivers are one of my favorite original creatures in fantasy, so I have brought them to D&D, with a mix of existing MTG lore and my own homebrew lore.

Group Encounters

A group sliver encounter should generally consist of several Sliver Hive Guards and/or Sliver Hive Drones with maybe one or two slivers with very generic adaptations to buff the group. When the group experiences something new that is considered a threat, a Guard or Drone can use its action to evolve into a type of Sliver. When it does, the statblock of the Guard or Drone is replaced by the new statblock. The new sliver removes all damage dealt and conditions it was affected by. For example, if a party that consists entirely of spellcasters fights a group of slivers, the drones might become Crystalline Slivers and Gemhide Slivers as these are adapted to specifically fight against spellcasters.

Sliver adaptations are immediate, so while the sliver has to use its action to evolve, the moment it does all other slivers in the area instantly gain the same benefits.

Solo Encounters

Fighting a single sliver on its own poses very little threat unless its adaptation is so powerful that it presents a threat to the entire party. But beware, a sliver within range of its Synaptic Lord immediately alerts it of what is going on with their hivemind, and thus the killing of a single sliver could bring down the might of the whole colony upon the party.

Synaptic Lords

Synaptic Lords are extremely intelligent, and through the colony can experience the entirety of the the territory around them. Depending on these experiences, the Lord enacts the slivers around it. A hive that is left undisturbed by the civilizations around it might leave the local populace alone and only hunt wild animals. If the hive's scouts and hunters are constantly attacked by people, the Lord might start going after villages preemptively to protect its brood.

A Synaptic Lord almost never leaves the heart of the hive unless forced to, as such any party that wants to take out a sliver colony, has to venture deep into a hive in order to find the Synaptic Lord. The Lords are always guarded by many Hive Guards and slivers with evolutionary adaptations built for protecting their leader.

Sliver Features

A sliver can be under the effect of any number of other sliver abilities at any given time. If there are 10 different slivers, then each one has ten different abilities. It is important to note that multiple features by slivers of the same name do not stack. So surrounding Slivers would not get a +2 AC bonus from having two Armor Slivers within range, however if one of them died, they would retain the +1 bonus since there is still an Armor Sliver in the area.

Sliver abilities that do the same thing, but are from different types of slivers do stack however. For instance, the colony has a +1 AC bonus from an Armor Sliver, if a Megantic Sliver appears then the AC increases to +4, as both are different creatures with abilities that grant a bonus to AC.

Sliver Statblock Integration

Each sliver has its unique ability integrated into its statblock by default. So A sliver that increases the size of slivers will already be bigger, a sliver that increases the attack bonus of slivers will already have a bonus to its attack, etc, etc. This means you never need to alter a sliver that is granting an ability, just all the others around it.

Base Sliver Forms

These are the stages of a sliver's life cycle that have experienced no adaptations.

Evolved Slivers

These slivers have adapted to the world around them in a myriad of ways to aid the colony.

On a successful save, a creature takes half of the damage dealt and it pushed up to 5 feet away.

Sliver Hivelord

A Hivelord is a specialized Sliver Queen that is born from conflict. When the slivers from a colony are often hunted or attacked by outsiders, or the hive itself is under constant threat, a Queen will become a Hivelord in order to protect its progeny. When this happens, the Hivelord's influence greatly hardens and reinforces the bodies of its brood, making them much harder to kill.

Hivelord's are dangerous Synaptic Lords, as they use their hives to actively seek out and destroy other sentient life. A Hivelord believes that any species that would do its colony harm must be eradicated regardless of reason. Many innocent villages have been annihilated by these tyrannical colonies, unaware that their execution is often the folly of some other settlement.

Sliver Legion

There are few things more terrifying then a tide of chittering claws washing over everything in its path, causing a seemingly mindless swath of destruction in its wake. Such is the Sliver Legion. When a colony loses its Synaptic Lord, the slivers become mindless feral animals merely striking out to survive with no purpose. However when one of these sliver's becomes aware of itself and begins the slow evolution into a Synaptic Lord, other slivers are drawn to it. The burgeoning queen surrounds itself with as many other slivers as it can, and the Legion is formed.

A Sliver Legion has one purpose, feed the queen. They forgo all evolutionary adaptations and focus solely on keeping their new leader alive, caring not for who or what lies in their path. A Legion can wipe out an entire countryside inside of a day before stopping to rest for only a few hours. Once the queen has fully matured, the Legion will begin building a hive where ever they have ended up, creating a true sliver colony.

Legendary Resistance (3/day). If the Hivelord fails a saving throw, it can choose to succeed instead.

Magic Resistance. The Overlord has advantage on saving throws against spells and other magical effects.

Overlord's Influence. The Overlord's influence acts as a 60 ft. aura that surrounds it. Any creature that enters the aura for the first time in a turn, or starts its turn there must make a DC 21 Constitution saving throw. On a failed save, the creature immediately mutates into a Sliver, replacing its statblock with a Sliver Hive Guard. A creature that succeeds on the save is immune to the aura for 24 hours. Any creature turned into a sliver in this manner is completely under the Overlord's control and cannot be changed back until the Overlord dies, is no longer on the same plane of existence, or by the wish spell. A Sliver from another hive that enters the aura automatically assumes the Overlord as its new Synaptic Lord. Undead and Constructs are immune to the aura.

Evolutionary Apex. The Overlord maintains complete control over a creature that is affected by its influence while they are on the same plane as it.

Innate Spellcasting. The Hivelord's innate spellcasting ability is Intelligence (spell save DC 21, +13 to hit with spell attacks). It can innately cast the following spells, requiring no components

Detect. The Overlord maker a Wisdom (Perception) check.

Spontaneous Brood. (Costs 3 Actions) The Overlord disgorges 1d10 slivers of Large size or smaller under its control.

Sliver Overlord

Often referred to as 'the end of evolution,' a Sliver Overlord is truly the apex of the species. So powerful is its psychic pheromones that any creature within close proximity to the Overlord will immediately mutate into a sliver under its control. These horrific titans of sliverkind are reviled even by other Synaptic Lords, as their broods will bend the knee to the Overlord against their will if the Overlord ever touches their minds.

While other Synaptic Lords lay eggs that hatch into sliver hatchlings and become hive drones and hive guards as they mature, Overlords give live birth to fully formed slivers that have already been assigned evolutionary traits according to the will of the Overlord. Because of this method of reproduction and the Overlord's iron grip on the minds of any sliver that comes into contact with it, they are near impossible to stop once they set out a course of action.

Sliver Queen

The most numerous of the Synaptic Lords, Sliver Queens are what almost every Synaptic Lord starts out as. They are the core of their colony, a brood mother who experiences the world through the colony's adventures.

While a Sliver Queen may seem like the most basic of the Synaptic Lords, it is also the one most willing to speak with other races that come into contact with a colony. This doesn't always mean peace between the races, but can often lead to a tentative agreement. The Queen keeps her hive out of the local's resources and the locals leave the colony's feeding grounds be.

Druid

Circle of the Hivemind

There are those who study slivers to such a degree that they have tapped into the hivemind, forever altering their magic. These druids shapeshift into slivers in order to get closer to the colony, and are often studied by Synaptic Lords for their tenacity.

Ranger

Hivestone Symbiote

Some who find hivestone shards and taste the hivemind's power desire more. Hivestone Symbiotes are individuals who graft and implant hivestone shards into their body, granting them insight into sliver hives and the colonies within.

Synaptic Lord Features

Bonus Cantrip

When you choose this patron at 1st level, you learn the mind sliver cantrip if you don't already know it.

It is affected by your blast shapes where it makes sense for the spell to have such a function, but cannot be altered by blast shapes with the transfiguration tag.

Expanded Spells

The Synaptic Lord grants you access to a special pool of spells. You learn additional spells when you reach certain levels in this class, as shown on the Synaptic Lord Expanded Spells table. Each of these spells counts as a Warlock spell for you, but it doesn't count against the number of Warlock spells you know.

Chosen of the Colony

Also at 1st level, your patron bestows upon you some of the benefits of what it means to be a sliver. You are immune to being blinded and have resistance to Psychic damage.

Synaptic Changes

Finally at 1st level, your body begins to evolve in the same way as a sliver does. Choose an Evolved Sliver that has a CR equal to or less than half of your proficiency bonus. You gain the features of that Sliver. You can't gain features that would alter your form, such as a Constrictor Sliver's tail, or a Syphon Slivers tentacles.

You can choose a different Evolved Sliver to gain the features of whenever you finish a short rest.

Hivemind Expansion

Starting at 6th level, the adaptations to your form allow you to affect your allies. Sliver Adaptation features that you gain from your Synaptic CHanges feature apply to non-Sliver creatures of your choice within 30 feet of you.

Further Evolution

At 10th level, your body adapts well to the evolutionary changes of slivers. You can choose two Evolved Slivers to gain the features of with your Synaptic Changes feature.

Additionally, you are affected by the Sliver Adaptation features of other Slivers.

Sliverfication

At 14th level, your ability to adapt to the Sliver's evolutions has been perfected by your Synaptic Lord. You can now take Sliver Features that alter your form, and the range of your Hivemind Expansion increases to 60 feet.

Hive Stirrings

3rd-level conjuration

• Casting Time: 1 action
• Range: 60 feet
• Components: V, S, M (a small chunk of material from a sliver hive)
• Duration: Concentration, up to 1 hour
• Classes: Druid, Ranger, Warlock

You summon the colony's own to come aid you. Two Sliver Hive Guards appear in unoccupied spaces that you can see within range.

The summoned Slivers are an ally to you and your companions and believes you to be their Synaptic Lord. Roll initiative for the summoned Slivers as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.

The DM has the Slivers statistics

At Higher Levels. When you cast this spell using a spell slot of 5th-level or higher you summon three Sliver Hive Guards, four at 7th-level, and five at 9th-level.

Sacred Hive

7th-level Conjuration

• Casting Time: 1 hour
• Range: 120 feet
• Components: V, S, M (The spinal fluid of a Synaptic Lord worth at least 5gp)
• Duration: 24 hours
• Classes: Druid, Warlock

You cause a sliver hive to shimmer into existence on ground you can see within range. The hive must fit within an unoccupied cube of space, up to 120 feet on each side, and can extend underground by the same amount. The hive remains until the spell ends.

You make all decisions about the hive's appearance, layout, and how many chambers it has. The hive is enclosed and only has one entrance, which you choose the location of. The hive's interior is a series of tunnels that leads to various chambers that are large open spaces. You decide whether the hive is magically illuminated and whether that illumination is bright light or dim light. The hive echoes with the ambient sounds of clicks and chitters even when there are no slivers within. The tempurature of the hive is always comfortable.

While the spell is active, you are considered the Synaptic Lord of the hive, and any Sliver that enters the hive must make an Intelligence saving throw against your spell save DC. On a failed save, the Sliver assumes you as its new Synaptic Lord. Any Sliver without a Synaptic Lord that enters the hive automatically fails the save and Synaptic Lords have advantage on the save. Slivers that believe you to be their Synaptic Lord can travel up to a mile away from the hive before your influence vanishes and they return to whatever hivemind they were a part of before you.

In addition, the sensors created by Divination spells can't appear inside the hive, and creatures within can't be targeted by Divination spells.

The hive is made from opaque magical force that extends into the Ethereal Plane, thus blocking ethereal travel into the hive's interior. Nothing can physically pass through the hive's exterior. It can't be dispelled by dispel magic, and antimagic field has no effect on it. A disintegrate spell destroys the hive instantly.

Casting this spell on the same spot every day for a year makes this effect permanent.

Conjure Sliver Colony

8th-level conjuration

• Casting Time: 1 action
• Range: 60-feet
• Components: V, S, M (the severed claw of a Synaptic Lord worth 1,000gp)
• Duration: Concentration, up to 1 hour
• Classes: Druid, Warlock

You summon the might of the colony to fight for you, they appear in unoccupied spaces that you can see within range. The following Slivers appear

• One Evolved Sliver of your choice of CR 3 or less.
• Two Sliver Hive Guards
• Four Sliver Hive Drones
• Eight Sliver Hatchlings

The summoned Slivers are an ally to you and your companions and believes you to be their Synaptic Lord. Roll initiative for the summoned Slivers as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.

The DM has the Slivers statistics.

Version 1.0

• More sliver statblocks. Decided to not care about alphabetical order for the future additions, as having to play musical chairs with the images was getting way to tedious.
