Streetfighter

Raised on the streets you can use unique abilities to gain advantages in a variety of scenario's, whether its a tavern brawl or shady dealings. 

Sprint burst

Gain an additional 5ft of movement speed at 3rd level, 9th, 13th and 17th level.

Also when you take the dash action you gain extra movement speed equal to 5 times your dexterity bonus. You can use this additional movement equal to your proficiency bonus.

Dead hard

Gain this feature at level 3 when you choose this subclass. When a creature fails an attack on you or fails a grapple check, you may use a reaction to move half of your movement speed away from that creature without provoking an opportunity attack.

Blindsided

When you take an attack after hiding non-magically make a stealth check contested to the passive perception of the creature you are attacking. If succeeded, you remain hidden until the start of your next turn only to the creature you are attacking.

Sloppy butcher

For every consecutive attack that you hit, +1 to your next sneak attacks attack roll and damage. This stacks until you use your sneak attack. The maximum accumulated bonus can only equal your rogue level.

Unrelenting

If you miss an attack, you can use your reaction to make an additional attack which expends all sloppy butcher stacks. This attack has sneak attack damage with the additional sloppy butcher damage which would have otherwise been wasted. On a nat 1 this fails, on a nat 20 you are allowed to keep your bonuses for the next sneak attack.
