History & Lore
Born from the imagination of the cosmos, the DND Astral Dreadnought’s origins are shrouded in mystery.
Ancient texts and sage lore suggest that these creatures were created by deities or powerful cosmic entities to serve as guardians of the Astral Plane.
They are tasked with maintaining the balance and order of the multiverse by any means necessary.
The Astral Plane, a realm of thought, dream, and possibility, serves as the perfect home for these titans.
The Dreadnought roams this timeless space, a void filled with floating islands of debris and the remnants of failed magical experiments, ever vigilant for intruders.
Types of Astral Dreadnoughts
There are rumored to be several types of Astral Dreadnoughts, each adapted to their specific roles within the Astral Plane:
- Guardian Dreadnought – Protectors of ancient astral ruins and celestial vaults.

- Sentinel Dreadnought – Stand watch over gateways and portals, preventing unauthorized access.
- Harbinger Dreadnought – Foretell significant cosmic events and guard secrets of the universe.
- Elder Dreadnought – Ancient and powerful, these Dreadnoughts are said to possess wisdom and abilities far beyond their kin.
Each type brings a unique aspect to the cosmic ballet of the multiverse, embodying the diverse and dynamic roles required to maintain the equilibrium of existence.
What Do They Look Like?
Imagine a creature so vast that it dwarfs even the largest of dragons.
You actually don’t have to imagine because the image right above this section shows an amazing picture.
I can say that because AI made it (albeit with simple prompts from me).
An Astral Dreadnought has a massive, humanoid upper body, complete with two hulking arms ending in vicious claws.
Its lower half is serpentine, allowing it to navigate the astral currents with ease.
Its head is a terrifying visage of destruction, with a single, cyclopean eye that can stop magic in its tracks.
The creature’s skin is a tapestry of cosmic hues, reflecting the nebulous colors of the Astral Plane itself.
In battle, the Astral Dreadnought is a force to be reckoned with for any player group.
It uses its massive size and strength to overpower foes.
While its innate magic resistance and the antimagic cone emitted from its central eye make it nearly invulnerable to spell-based attacks.
It prefers to engage its enemies up close, tearing them apart with its powerful claws and bite.
However, it is also intelligent enough to use the terrain of the Astral Plane to its advantage.
The dreadnaught will ambush unwary travelers or using astral debris as weapons.
The Astral Dreadnought’s Multiattack feature allows it to unleash multiple attacks in a single turn, demonstrating its overwhelming combat prowess.
Typically, this involves a combination of its bite and two claw attacks.
The creature can target multiple opponents or focus its fury on a single, unfortunate target.
The Dreadnought remains a constant, pressing threat to the entire adventuring party, demanding strategic positioning, and careful management of resources to mitigate its offensive onslaught.
The Astral Dreadnought possesses several Legendary Actions.
Meaning, it can and will take actions outside of its turn.
These legendary actions include:
- Donjon Visit: This action teleports a target into a demiplane prison within the Dreadnought’s body, effectively removing them from the battle until they can find a way to escape. It’s a powerful control tool, capable of temporarily neutralizing key players in the adventuring party, forcing them to deal with not just a combat challenge, but a puzzle under duress.
- Psychic Projection: The Dreadnought can project a wave of psychic energy, dealing substantial psychic damage and potentially imposing debilitating conditions on its foes. This action highlights the creature’s ability to dominate the battlefield not only through physical might but through mental assaults, challenging players to protect both their bodies and minds.
In addition, the Astral Dreadnought boasts several other powers that contribute to its fearsomeness:
- Antimagic Cone: Emitted from its single, central eye, the Antimagic Cone nullifies magic in a wide arc in front of the Dreadnought. Spells cannot be cast into or out from the area, and active magical effects are suppressed. This power can dramatically shift the tide of battle, especially against parties reliant on magic, forcing them to adapt to a purely physical confrontation or find creative workarounds.
- Astral Entity: As a creature native to the Astral Plane, the Dreadnought has innate abilities that make it perfectly suited to its environment. It can move through the Astral Plane with ease, ignoring many of the plane’s peculiarities that might hinder other beings. This trait allows it to ambush, pursue, or retreat with unmatched proficiency, making it a relentless hunter in its native realm.
- Legendary Resistance: The Astral Dreadnought’s Legendary Resistance allows it to shrug off effects that would otherwise alter its course of action, ensuring that it remains a constant threat. A limited number of times per day, if it fails a saving throw, it can choose to succeed instead. This power guarantees that the Dreadnought cannot be easily neutralized by a single lucky spell or effect.

How to Run an Encounter With a DND Astral Dreadnought
Here’s a guide on how to craft an unforgettable experience:
1. Set the Stage
Begin by establishing the setting.
Astral Dreadnought encounters typically happen in the Astral Plane, a realm of thought and memory, where the laws of physics and time often don’t apply.
Describe the surreal, star-filled landscape and the floating islands of debris.
The appearance of the Dreadnought should be a moment of awe and fear, emphasizing its colossal size and otherworldly nature.
2. Understand the Creature
Before the encounter, make sure you fully understand the capabilities of the DND Astral Dreadnought.
Consider how these abilities can be used not just for combat.
But to create interesting tactical situations and role-playing opportunities.
3. Highlight Its Intelligence
Astral Dreadnoughts possess a deep, if alien, intelligence.
They guard the Astral Plane against intrusion, which can add a layer of complexity to encounters.
Maybe the Dreadnought challenges the party with riddles or tests, or perhaps it seeks to negotiate with them to remove a greater threat to its realm.
4. Use the Environment
The Astral Plane’s unique properties can play a significant role in the encounter.
Characters might find themselves floating or suddenly falling through space.
Debris and astral entities can serve as both obstacles and aids in the battle.
Consider how the Dreadnought’s abilities interact with the environment, such as using its Antimagic Cone to disable magical items or spells that allow the party to navigate the plane.
5. Scale the Encounter
You should scale the encounter to suit your party’s level and abilities.
This doesn’t mean weakening the Dreadnought but rather finding creative ways for the party to engage with it.
Perhaps they must first disable a magical artifact that strengthens it or seek the aid of astral allies.
6. Offer Multiple Outcomes
Not every encounter with a DND Astral Dreadnought needs to end in combat or the party’s victory.
The creature might retreat if it deems the party not a threat to its realm, or it could capture them, leading to an escape scenario from within its donjon demiplane.
Alternatively, satisfying the Dreadnought’s challenge or quest could earn its respect or even a boon.
7. Focus on the Experience
The encounter with an Astral Dreadnought should feel epic and memorable.
Focus on building tension and excitement, using vivid descriptions and emphasizing the scale of the encounter.
The goal is to leave your players in awe of the encounter.
That’s true whether they triumph, negotiate a truce, or barely escape with their lives.
8. Prepare for the Aftermath
Don’t overlook the consequences of the encounter.
Surviving a meeting with an Astral Dreadnought could have significant repercussions in the Astral Plane and beyond.
Perhaps the party earns the enmity or gratitude of powerful cosmic entities.
Or they gain unique insights into the nature of the multiverse.
9. Encourage Creativity
Finally, encourage your players to think creatively.
Facing such a powerful foe head-on might not always be the best strategy.
The unique nature of the Astral Plane and the Dreadnought itself can inspire inventive solutions to the challenges they present.
Speaking of creativity, the next section shares some cool ideas for clever DMs.
