Dagger: Melee Weapon Attack: +9 to hit, reach 5 ft 10/20., one creature. Melee Attack: Hit 11 (1d4 + 9) piercing damage. Ranged Attack: Hit 14 (2d4 + 9). After a Ranged Attack, the dagger returns and can hit someone within range of the original target. If the blade travels more than 40 feet away from Yedri,  it drops from the air. It can chain between a number of enemies equal to Yedris' Challenge Rating.

Reflective Speed: Yedri can take the Dash action as a Bonus action. When doing this, on that turn he can also take the disengage bonus action as a free action

Paralyzing Breath: Yedri exhales paralyzing gas in a 20-foot cone. Each creature in that area must succeed on a DC 17 Constitution saving throw or be paralyzed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. During this time, anyone with the Negative Effects of Goblins Brand takes 1d6 Psychic damage per turn, and anyone with the Positive Effects of Goblins Brand heals 1d6 damage per turn

Deflection: Yedrio can use his mace to deflect or break any projectiles targeted at him. With a successful Dexterity Saving Throws equal to or greater than the attack roll, Yedri can deflect or break a projectile, taking no damage from it on a success. On failure, Yedri takes half the damage. After using this reaction, Yedri has an addition to his AC equal to his proficiency bonus

Shielding Spirit: Whenever someone Branded by Yedri is attacked or makes an attack, Yedri subtracts or adds his proficiency bonus to the attack roll, or the AC of the Branded. After this, the Branded is granted an addition to their AC equal to their Proficiency Bonus

Has one Legendary Action

Pesky little ^$(&(@! (1 Action): Yedri can move double his movement speed without provoking opportunity attacks. During this time his climbing and swimming speed equals his walking speed when doubled.
