Sneaky Bugger

Your small size and quick speed make you deadly against
larger foes.

• Increase your Dexterity score by 1, to a maximum of 20.
• When you use your Nimble Escape trait to take the
  Disengage action, your speed increases by 10 feet until
  the end of your current turn.
• You can attempt to hide even when you are obscured only by a creature that is at least one size larger than you.

Also, instead of the damage caused by your Fury of the Small
feature, you can opt to have one of the following effects occur
when you damage a creature with an attack or a spell and the
creature's size is larger than yours:

• The creature must make a Constitution saving throw with
  a DC of 8 + your proficiency bonus + your Dexterity
  modifier. On a failed saving throw, the creature is blinded
  until the end of its next turn.
• The creature's movement speed is reduced by half until
  the end of its next turn.
• The creature must make a Wisdom saving throw with a
  DC of 8 + your proficiency bonus + your Dexterity
  modifier. On a failed saving throw, your next attack against
  the target is made with advantage as long as you make the
  attack before the end of your next turn
