You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Your Charisma score increases by 2, and one other ability score of your choice increases by 1.

Aetherborn typically come into being as adults. Those that live in the ethereal plane seem to be immortal, while those that live in other planes live no more than 60 years. However there are a few exceptions but these are exceedingly rare, more so than the Aetherborn themselves.

Aetherborn are typically driven by their interests, making them chaotic neutral. Some of them, mainly those bound to protect a secret, can be lawful. They usually don't take a side in the moral alignment unless they have no choice but to do so or their soul constituent is extraordinarily pure either too good or evil. As a rule, aetherborn are driven by hedonism and self-interest, making them neutral at best and thoroughly evil at worst. Neutral aetherborn might devote much of their time (and wealth) to parties and social activity, while evil aetherborn are usually involved in the criminal underworld.

Aetherborn are about the same size as humans, ranging from 5 to 6 feet tall. They are quite light—only about 60 pounds—and their weight diminishes as they age in other planes different to the ethereal plane. Your size is Medium.

Your base walking speed is 30 feet. You are always hovering 2 feet over the terrain. You can't fly or hover over canyons or other empty spaces. If you move more than 5 feet over an open space, you start falling.

Although you are a living being, you are considered a construct. You can't be healed by magical means while in this form and you can only regain HP by rolling hit die. You can't wield weapons while in this form. While in this form your armor class is increased 10 + Constitution modifier + your proficiency bonus. As you are immaterial any attack roll against you not performed by a magical, silvered, or adamant weapon or while not grappled or incapacitated is rolled with disadvantage. You have an advantage against rolls to get grappled or fall prone.

This can only be performed once per long rest

Being aetherborn makes your mind to be always at peace. When you sleep, you remain still for 4 hours, gaining the benefits of a long rest, while being fully aware of your surroundings. You have an advantage against magical effects to get charmed or frightened.

You have resistance to necrotic damage.

You can speak, read, and write Common and two other languages of your choice.

You gain proficiency in the Intimidation skill.

For many aetherborn, living as they do for indulgence and instant gratification, the concepts of “want” and “need” are virtually synonymous. But Aetherborn with this gift understand what it is to truly need, for they develop a hunger for life essence that far exceeds any desires they might have felt before their transformation. A gifted aetherborn who abstains from this feeding deteriorates even more rapidly than other aetherborn, while enduring unspeakable agony caused by the deprivation of life energy.

At the DM’s option, an aetherborn character can research methods of achieving this dark “gift.” The process is similar to inventing and manufacturing a rare magic item. But rather than aether, the process requires a variety of rare unguents and unusual ingredients that make up the cost of researching and undergoing the transformation.

An aetherborn with this gift gains a Drain Life ability, which is a natural attack that uses Strength for its attack and damage rolls, dealing 1d6 necrotic damage and restores the same number of hit points to the aetherborn. However, if the aetherborn goes for 7 days without dealing this damage, their hit point maximum is reduced by 1d6 per week. This reduction can’t be removed until the aetherborn has used their Drain Life ability and completed a long rest.
