Blink Thief

Some rouges have such amazing stealth is seems like they can turn invisible. Blink Thieves use magic to enhance their stealth and other roguish abilities. Blinking in and out of existence is sometimes more real than an exaggeration. 

Cunning Blink

Starting at 3rd level, you learn how to jump in and out of existence for a brief moment, then reappear a short distance away. As a bonus action, you can choose an unoccupied point you can see within 60 feet. You instantly teleport to that location. You cannot bring any other creature or special objects with you, aside from what you can normally carry. This ability provokes opportunity attacks if applicable. If a creature is within 5 feet of your chosen location, you can immediately use your action to make a melee weapon attack against that creature. You add your sneak attack damage to this attack, regardless of whether you surprised the creature or if you have advantage on the attack roll. However, you do not apply the damage if you have disadvantage, otherwise, the normal rules for sneak attack apply. You can use this feature a number of times equal to your Proficiency bonus, and you regain all uses after a long rest. 

Superior Blink

Starting at 9th level, you can optionally use your Cunning Blink using all your movement, rather than a bonus action. Yes, this means you can use it twice per turn. (movement and a bonus action) Also starting at 9th level, when you use this feature while you are in melee range of a hostile creature, this movement does not provoke opportunity attacks. Also at this time, if you are hit with an attack, or if you would make a saving throw against an area effect, (before the damage is dealt,) you can use your blink as a reaction to not receive any damage from the attack, or automatically succeed the saving throw, and appear in a random location within 20 feet. The DM randomly determines this location. 

Cunning Sneak

Starting at 13th level, as an action, you can expend two uses of your Cunning Blink to become Invisible for 1 minute. While invisible in this way, you can move and take actions as normal. This ends if you are incapacitated. You can end this at any time, without requiring an action. 

In addition, you can expend two uses as an action to gain a climbing speed equal to twice your walking speed for 10 minutes. This movement can be used to climb up flat or slick surfaces, and upside-down on ceilings. 

Blink Master

Starting at 17th level, you can activate your Cunning Blink using 5 feet of movement, In addition, you can bring one willing creature of your size or smaller with you. 

Also at 17th level, you regain all uses of your Blink after a short or long rest.
