Thanks to your cat eye mutation, you have superior vision in dark and dim conditions. You can see in dim light within 120 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.

You have advantage on Wisdom (Perception) Checks that rely on hearing and smell.

Due to your mutations you have a much more powerful metabolism than normal Humans, granting you immunity to disease and resistance to poison.

You have a healing factor granting you a greater constitution and resistance to mundane forms of damage.

Nachtjagers cannot sleep due to their elven heritage being drawn forth, because of this they are immune to magic sleep and have advantage against being charmed. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

You have advantage on an attack rolls against creatures if at least one of the your allies is within 5 feet of the creature and the ally isn't incapacitated.
