The Crystal Tiefling

The Crystal Tiefling is an alternate breed of Tiefling, which holds an echo of one of many planes within them rather than the influence of one of the layers of hell. Tieflings of this nature develop bodies and characteristics that resemble various gemstones and minerals, giving them distinct appearances. They are absurdly rare and blur the line between their own infernal heritage and other planetouched beings. Each innately gains access to magic that embodies the plane that seeds their power, and also the ability to manifest an aspect of those planes for a brief period of time.


This bundle is meant to introduce the spectacle that is the Crystal Tiefling, as well as offer a variety of options for players who wish to use them, and DMs who wish to include them as NPCs. The content should provide a widely varied experience that can be used to generate dozens of Crystal Tiefling NPCs, as well as options such as subclasses that can be used for characters that aren't Crystal Tieflings. The following are included:

  • A new base Tiefling race( the Crystal Tiefling) 
  • 10 subraces based on the four Elemental Planes, the Positive and Negative Energy Planes, as well as Elysium, Pandemonium, Mechanus, and the Shadowfell.
  • Ideal, Flaw, Quirk, and Origin tables
  • 12 Crystal Tiefling-specific feats
  • 8 new subclasses for the Barbarian, Fighter, Monk, Paladin, Petal Knight, Rogue, Sword Saint, and Warlock. 
  • 8 Eldritch Invocations
  • 1 Saint Myth Weapon artifact
  • 7 Crystal Tiefling NPCs



The following are basic breakdowns of the subclasses contained within the product, all of which are themed after invoking elemental or planar powers, and are not limited to use with the Crystal Tiefling.

Barbarian - Path of the Whispering Voice
A barbarian who hears whispers upon the winds, and gains their aid in their exploits. Others may see them as savages who whisper to empty air, but they speak to unseen spirits who embody the wind itself. As their familiarity with this unseen ally grows, so too does their power to control the wind and focus in as they wish.
Fighter - Hearthguard
A heroic figure who draws upon an innate control over flame. The fire they conjure is tied to their spirit, and when focused can grant them undying fortitude in combat. Weapons glowing white-hot, they charge through their opposition as heroic or brutal champions.
Monk - Way of the Crystal Hand
The world is made of many folded over one another, with echoes of what we know stretching out into the untold reaches of infinity. These monks train themselves to see through many echoes of the world at once and make use of the mirror worlds they see.
Paladin - Oath of Banishment
Known as Edgekeepers, these paladins take upon themselves the difficult task of protecting their plane from invaders from beyond it. They do so with respect to the natives of others but keep a firm watch over the order between worlds. Their powers allow for banishment and seeing overlapping planes.
Petal Knight - Winecup Epithet
A warrior who excels in subterfuge and dealing with poisons. These duelists can benefit from powers that allow them to become invisible at will, avoid the brunt of the damage from attacks and imbue their weaponry with a natural poison that they inflict on those they strike.
Rogue - Rimeknife
Infused with an icy aspect, these rogues strike surgically at opponents. They drift like ghosts within clouds of fog and snow, cutting into opponents when they least expect it. They can trade amounts of their sneak attack dice to inflict secondary effects upon their target.
Sword Saint - Way of the Snow White Sleeve
There once existed a calming swordswoman who constructed a sword from the heart of a frozen elder water elemental and a fragment of their own soul. Those who follow this path replicate their teachings, focusing on turning their spiritual energy into ice and snow to freeze and slow their enemies.
This document includes their Sword Saint Weapon, the Snow Sleeve, an artifact-rarity longsword with various freezing effects. 
Warlock - The Cataclysmic
Forging a pact with an Elder Elemental or similar beast from the Elemental Planes, these Warlocks become agents for these cataclysmic figures. In return they gain a powerful elemental agent they can manifest and command, which grows stronger as they do. At the height of its power, they can merge with their elemental agent and embody the power of their patron directly.
This document includes 8 Eldritch Invocations meant for the Cataclysmic Warlock.

(The Crystal Tiefling and all included elements were made for the Nat19: Vestige of Ophiuchus D&d 5E stream on Twitch, streamed every Saturday at 1 PM PST on the Nat19Official Twitch channel. Come join us if you'd like to see the contents in action!)

Genuinely love this expansion, I noticed the choice in avoiding the "traditional" stones people thin about when people tackle gem variants of thing. Is there a plan to expand upon this idea in a future expansion, or is this a basis to see how it expands from other people's creativity as well?

Follow up because I forgot to ask, is there a difference between the somnus Domina download and the nat 19?

Logan L July 18, 2022 9:04 pm UTC
No difference~! The Nat19 one is just a Fantasy Grounds MOD, while the other two are pdfs.

I'm sorry I'm not sure if this is the right place to bring this up but I bought this pdf and absolutely loved it but now it's not showing up in my library or purchase history....

I'm not sure what would cause that issue. Did you perhaps accidentally buy it with a different account or archive it?

I gotta ask... What's the point of them being tieflings and not some form of genasi?
Customer avatar

Being a fun alternate concept, and that fact that fundamentally it just is what it is. If they were genasi they'd be genasi. The line of thinking there stops at "we have genasi" and it simply doesn't exist. The inspiration here began with an art concept from the artist involved provoking thought, and me offering to see it through and find a way to make the concept work without breaking how planetouched aspects worked. It was made purely because inspiration struck.

If you ultimately just want to use genasi, genasi still exist. People love options however, and support for this product has made it pretty clear that the Crystal Tiefling idea is something that's resonating with a lot of people. That's reason enough to have made it.

Thank you for the clarification, but somehow your response indicates it rankled you, as the justifications indicate a degree of bitterness. Am I wrong or just reading between the lines too much? If I'm not wrong, then I think you've fundamentally misunderstood where I was coming from. I was curious, not critical.

You're reading into it too much. I was just being exhaustive, and trying to say more than "it is what it is". Unfortunately, I suppose, that can sometimes be read as being defensive. I personally choose to imagine the most favorable tone when I only have text to go off of.

Alright, thank you for the reassurance and I hope I didn't waste your time :)

Certainly not~!

You are right. They should be genasi.

If their planetouched aspect was from the elemental planes that might be the case.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
