The Blinkwalker

Blinkwalkers learn to use their teleportation to put themselves in strategic positions to gain advantage in combat and to put their enemies in positions of disadvantage.

Blinkstep

At 3rd level, you gain a teleporting speed equal to your walking speed. Teleporting is a mode of movement for you. Whenever you would move, you may instead, briefly surrounded by a shadowy mist, instantly teleport in any direction to an unoccupied space you can see, a maximum distance equal to your remaining movement speed. When teleporting this way, a short cacophonous sound can be heard up to 30 feet away from where you disappear, as well as from where you appear. As with other types of movement, you deduct the teleported distance of each part of your move from your movement speed until it is used up or until you are done moving. You cannot use this feature if your speed is 0, or if you are wearing medium or heavy armor. When you teleport this way, you can bring your equipment with you, and any objects you are holding as long as their weight doesn't exceed what you can carry.

Sudden Strike

Once per turn, when you teleport to a space adjacent to any creature you can see, you have advantage on the first melee attack you make before the end of that turn against that creature.

Blink Response

Once per turn, whenever a creature hits you with an attack, you can use your reaction to teleport up to 10 feet to an unoccupied space you can see, causing that attack to miss you. If you teleport this way to a space adjacent to any creature, you can make an unarmed strike against that creature as part of the same reaction. You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses when you finish a long rest.

Unbridled Step

You can cast the Teleport spell once with this feature, requiring no verbal component, and you regain the ability to cast it this way when you finish a long rest.
