You have advantage to all Stamina checks to concentrate on spells and other tasks.

You can create a spatial rift as a bonus action at any point you can both see and normally reach (by walking, climbing, or swimming) to within 30 feet (or your normal walk speed, whichever is higher). After the rift is set, you can teleport to it as a bonus action, it as if using the blink step spell. This is useable once per long rest, and acts as the spell for all other purposes. The rift remains up to 1 minute, and can be used so long as you are within 100 feet of it (so long as you placed it within the normal range beforehand).

You know the chill touch cantrip and can cast it normally (caster level equal to your character level). When you reach 3rd level, you can also cast detect magic as a 1st level spell. When you reach 5th level, you can also cast the shadow word pain spell as a 2nd level spell. Charisma or Intelligence (your choice) is your spellcasting ability for these spells, and you use your mana pool for these abilities (even if you are not normally a spellcaster). While you use such abilities (and after using them for one hour), your eyes glow a pale white. If you can already cast such spells (and have a sufficiently high caster level), they are always prepared for free.

Your Dexterity score increases by 2, and your Charisma score or Intelligence score increases by 1.

Although elves reach physical maturity at about the same age as humans, the elven understanding of adulthood goes beyond physical growth to encompass worldly experience. An elf typically claims adulthood and an adult name around the age of 100 and can live to be 750 years old.

Elves love freedom, variety, and self-expression, so they lean strongly toward the gentler aspects of chaos. They value and protect others’ freedom as well as their own, and they are more often good than not. The drow are an exception; their exile into the Underdark has made them vicious and dangerous. Drow are more often evil than not.

Elves range from under 5 to over 6 feet tall and have slender builds. Your size is Medium.

Your base walking speed is 30 feet.

Accustomed to twilit forests and the night sky, 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.

You have proficiency in the Perception skill.

You have advantage on saving throws against being charmed, and magic can’t put you to sleep.

You can speak, read, and write Common and Elvish. Elvish is fluid, with subtle intonations and intricate grammar. Elven literature is rich and varied, and their songs and poems are famous among other races. Many bards learn their language so they can add Elvish ballads to their repertoires.
