Homebrew Crystalia Race Details

"What? A C-Crystalia?"
"You're kidding! A Crystalia here in Torwa?"
"Blankets, man, blankets! Fetch them now before we all freeze to death!"
"I'm afraid I'm going to have to ask you to leave our territory, miss. Finish your meal and go."
"But poor Lily! I mean, she's not even radiating frost now!"
"And can you guarantee that she won't be tomorrow as well? Look, I don't expect you to understand, but we live by a good maxim here. See some demihumans, run away. See one demihuman, send it away."

— Granblue Fantasy, A Peace of the Pie

A rarity in the skies, Crystalia are mostly unknown to most people. But in the places where they are, especially their island of origin, the all-female demihuman race has long been regarded with fear. Owing not to their appearance or culture, this fear stems from their very nature - beings of ice that exude a deadly chilling aura from their bodies as naturally as breathing. Mostly reclusive, envoys, or Princesses as they are called within their culture, are sometimes seen journeying the skies for mysterious purposes, usually keeping just as reclusive even abroad. In recent years though, they've become more open about their culture and interacting with others, in part because of a recent peace brokered on their home island among the human and demihuman races, which is also due to the other factor: gaining the ability to control and restrict their freezing aura.

Daughters of the Snow Maiden

Crystalia all originate from the Ice Crystal Palace, propagated from their parent and sovereign, the Snow Maiden. While the Snow Maiden herself appears as a wreath of glowing ice crystals with a voice that only Crystalia can hear, the Crystalia themselves have relatively human appearances. All holding the appearance of beautiful young women, they are most easily differentiated by their long, pointed ears that stick out perpendicular from their heads. They also tend to have piercingly blue eyes, though the color can vary from gray to nearly greenish in hue. Their hair as well tends towards shades of blue but with even more variation than their eyes, ranging from silver to outright aquamarine. Their features tend towards being delicate, their pale skin in contrast with the colorful crystals that decorate their clothing and make up their home. Added to the fact that they don't age in appearance beyond what looks like human adolescence and they overall give an almost fey impression.

Quiet and Reclusive

Though there are exceptions, and recent years have seen a change across their culture, most Crystalia are quiet and insular in nature. Due to their close bonds with fellow Crystalia as an extended family and their history of being shunned by all other races, most Crystalia are shy of other races and cautious of the outside world in general. This comes more from a reluctant acceptance of their poor match with species that require temperatures above freezing to live than of any distrust though, so they don't actually regard others too coldly and if a bond can be formed with a Crystalia, a lifelong friend might be made.

Most Crystalia are adverse to direct confrontation, tending towards passive resistance, with their freezing aura serving as the ultimate defense. Many are adept spellcasters though and they are not shy to defend their home and family as well as those they consider part of either.

Crystalia Names

Given names by their progenitor the Snow Maiden, most Crystalia bear names with soft, lilting tones that match the translucent crystals of the palace where they live. Given the small size of their community, almost all Crystalia only have a single given name with no family or clan name since they all belong to the same extended family under the Snow Maiden's guidance.

Female Crystalia Names: Lily, Erin, Allie, Tia, Eve, Amelie, Lina, Elle, Millie, Letty, Lia, Tali, Val, Mel

A Local Fear

While there is a great history of cross-cultural strife and fear of the Crystalia on their home island, in the skies at large, Crystalia are simply too unknown for most people to be afraid of them. The world regards them with curiosity so long as their icy nature remains in control or hidden, and in turn the larger world to which they previously isolated themselves from fascinates the few Crystalia who are brave enough to leave the Ice Crystal Palace. While their strange appearance can sometimes draw idle attention, they're overall not remarkable enough for most people to notice - unless some kind of frozen accident happens.

Crystalia Traits

Crystalia have naturally icy powers thanks to their frozen origin.

Ability Score Increase

Your Intelligence score increases by 2, and your Wisdom score increases by 1.

Age

Crystalia age at the same rate as humans but appear to stop aging during adolescence anywhere between 12-20 years of age. Mental maturity is still achieved at the same rate though despite any appearance of halting physical growth. Their lifespans are about the same as humans.

Alignment

Due to their isolated society and reclusive nature, most Crystalia tend towards neutral rather than good or evil. Because of their close knit community, they also tend towards lawful, though the ones that dare to venture outside of their frozen homelands would be the ones most likely to buck the trend.

Size

Crystalia are about the same size and build as young humans. Your size is Medium.

Speed

Your base walking speed is 30 feet.

Frozen Body

You have resistance to cold damage and vulnerability to fire damage.
Any action, spell, feat or trait you use that would deal acid, fire, lightning or poison damage deals cold damage instead. The appearance is likewise cold and ice related, and any secondary effects that no longer make sense (e.g. causing items to ignite) are removed or replaced with a cold-related effect instead at the DM's discretion. This does not change the effects of weapons or other items.

Natural Cold

You know the frostbite cantrip. When you reach 3rd level, you can cast the armor of agathys spell as a 2nd-level spell once with this trait and regain the ability to do so when you finish a long rest. Intelligence is your spellcasting ability for these spells.

Freezing Aura

The Crystalia have learned to suppress their deadly freezing aura when traveling or meeting other people, but they can always unleash it if the situation calls for it. As a bonus action, you can unleash your freezing aura in a 10ft radius. All non-Crystalia creatures, friend or foe, that begin their turn in that area must make a Constitution saving throw. The DC for this saving throw equals 8 + your Wisdom modifier + your proficiency bonus. A creature takes 1d4 cold damage on a failed save, and half as much damage on a successful one. The radius and damage can be increased to 15ft and 1d6 at 5th level, 20ft and 1d8 at 9th level, 30ft and 1d10 at 13th level, and 40ft and 1d12 at 16th level. The aura can be unleashed using the radius of previous levels, but the damage decreases accordingly.
Whenever you are struck by a critical hit, you must make a Constitution saving throw or you lose control and unleash your freezing aura at its maximum size and damage if it is not already. The DC equals 10 or half the damage you take, whichever number is higher.
You must use an action to suppress your aura.
