race features:
Your half-elf character has some qualities in common with elves and some that are unique to half-elves.
Darkvision
Thanks to your elf blood, you have superior vision in dark and dim conditions. 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.
Fey Ancestry
You have advantage on saving throws against being charmed, and magic can’t put you to sleep.
Skill Versatility
You gain proficiency in two skills of your choice.
To humans, half-elves look like elves, and to elves, they look human. In height, they’re on par with both parents, though they’re neither as slender as elves nor as broad as humans. They range from under 5 feet to about 6 feet tall, and from 100 to 180 pounds, with men only slightly taller and heavier than women. Half-elf men do have facial hair, and sometimes grow beards to mask their elven ancestry. Half-elven coloration and features lie somewhere between their human and elf parents, and thus show a variety even more pronounced than that found among either race. They tend to have the eyes of their elven parents.
Half-elves have no lands of their own, though they are welcome in human cities and somewhat less welcome in elven forests. In large cities in regions where elves and humans interact often, half-elves are sometimes numerous enough to form small communities of their own. They enjoy the company of other half-elves, the only people who truly understand what it is to live between these two worlds.
In most parts of the world, though, half-elves are uncommon enough that one might live for years without meeting another. Some half-elves prefer to avoid company altogether, wandering the wilds as trappers, foresters, hunters, or adventurers and visiting civilization only rarely. Like elves, they are driven by the wanderlust that comes of their longevity. Others, in contrast, throw themselves into the thick of society, putting their charisma and social skills to great use in diplomatic roles or as swindlers.
Half-elves use either human or elven naming conventions. As if to emphasize that they don’t really fit in to either society, half-elves raised among humans are often given elven names, and those raised among elves often take human names.
