You have proficiency in the Stealth skill

Your Bite is a Natural Finesse Weapon doing 1d6 damage.

Teleport (Recharge 4–6). The dog magically teleports, along with any equipment it is wearing or carrying, up to 40 feet to an unoccupied space it can see. Before or after teleporting, the dog can make one bite attack.

Your Dexterity score increases by 2.

Although Blink Dogs reach physical maturity at about the same age as wolves, the Blink Dog understanding of adulthood goes beyond physical growth to encompass worldly experience. An Blink Dog typically claims adulthood and an adult name around the age of 14 and can live to be 110 years old.

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

Your base walking speed is 40 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, and advantage on Wisdom (Perception) checks that rely on hearing or smell.

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

Blink Dogs 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 Blink Dog, and understand but not speak Sylvan.
