Although vulcans reach physical maturity at about the same age as humans, vulcans can live up to 250 years.

Vulcans tend toward the lawful and the good, although neutral is also possible. Evil vulcans are almost unheard of, with none mentioned in the historical record for more than a thousand years. Chaos is anathema to the vulcan mind and considered by vulcans to be a sign of mental illness.

Vulcans range from 6 to 7 feet tall and have slender builds, despite their strength. Your size is Medium.

Your base walking speed is 30 feet.

You have resistance to psychic damage and advantage against enchantment and illusion spells and effects. Magic cannot put you to sleep.

You have expertise in the Investigation skill and one other Intelligence-based skill of your choice.

You cannot be proficient in a skill that is not based on Strength or Intelligence, regardless of the options that your class, background, or a feat or feature may permit.

You have advantage on Strength (Athletics) checks.

Vulcans are trained from an early age in a technique known as the Vulcan Nerve Pinch. Also known simply as the nerve pinch, it targets a location on the neck between the head and the shoulder. No other creature can learn this technique.

A nerve pinch takes an action and can be performed only once after each initiative roll. No attack roll is required. The target must succeed on a Dexterity saving throw against your spell save DC or fall unconscious for 1 minute. The saving throw is made at disadvantage if the target is surprised or flanked. A tiny, huge, or gargantuan creature or a creature without a discernible neck is not affected.

At the end of each of its turns, and each time it takes damage, the target can make a Charisma saving throw against your spell save DC. The target has advantage on the saving throw if it is triggered by damage. On a success, the condition ends.

Vulcans are trained upon reaching adolescence in a technique known as the Vulcan Mind Meld, or simply the mind meld, which allows you to cast Detect Thoughts without material components.

If you are touching the creature's head, or the part of a headless creature's body closest to its brain, the target does not get to make a saving throw. However, in this case, you cannot shift your attention to another creature or the spell ends.

Once you have performed a mind meld, you cannot perform another mind meld until you have taken a long rest.

Katra transfer:

* At 10th level, as an action, you can mind meld to transfer your katra (soul) into a willing creature or simulacrum. While your katra is in the recipient (host), your body remains in suspended animation, although it continues to age, and is unconscious. You share the host's senses. If a creature, you can request telepathically that it communicate or perform another activity on your behalf; however, you cannot compel it to do so unwillingly. If a simulacrum, you can control it. The katra retains the katra transfer ability within the host. In all other respects, the host retains its autonomy.

* At 20th level, as a bonus action, if you fall to 0 or fewer hit points, you can use a mind meld to transfer your katra in the same way before falling unconscious or dying.

Intelligence is your spellcasting modifier when you use this feature.

You are proficient in the vulcan harp, also known as the vulcan lute, a twelve-stringed musical instrument tuned on a diatonic scale and renowned for its soothing sound. When playing the vulcan harp, you have advantage on Charisma (Performance) checks.

Vulcans don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) 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 can speak, read, and write Common and Vulcan.
