Voidborn

Being of Void. Your presence sucks the light from around you. Within a 5 ft. radius surrounding you, bright light becomes dim light, and dim light becomes non-magical darkness. You have true sight within that range, and also do not require air, food, drink, or sleep   Cosmic Resilience. You are immune to being poisoned and poison damage, and are resistant to necrotic damage.   Magic Susceptibility. You have disadvantage on saving throws against spells and other magical effects.   Volatile Permanence. As a bonus action, you temporarily fade from existence and reappear in an unoccupied space within 60 ft. that you have either occupied before or can see. You remain in that location until the start of your next turn, at which point you reappear to your original location. If when you teleport or reappear the space is occupied, you instead appear as close to the space as possible (determined by the GM), taking 1d6 force damage for every 5 ft. away from the original destination. Once you use this feature, you must finish a long rest before you can use it again.   Lingering Traits. Instead of taking +1 to all stats, you may instead choose to take +1 in only two stats, and gain one feature from the race your character was before they became Riftborn. This feature is meant to reflect any natural racial abilities that would likely have been retained after the character's transformation, and is more prone to occur in Riftborn who've had minimal physical change from their original race.
