Dexterity

The core 2014 Elf increases Dexterity by 2.

Darkvision

The Elf can see in dim light within 60 feet as bright light and darkness as dim light, without discerning normal colors in darkness.

Keen Senses

The Elf gains proficiency in Perception.

Fey Ancestry

The Elf has advantage on saving throws against being charmed, and magic cannot put the Elf to sleep under the 2014 wording.

Trance

Elves do not need ordinary sleep. Four hours of trance provide the rest benefit described by the 2014 trait.

Languages

Common and Elvish.

Subrace layer

High Elf and Wood Elf add their own 2014 ability-score and feature choices. Those subrace traits are separate from later standalone elven species designs such as Astral Elf.
