Raven Queen's Initiate

You have martial training that allows you to perform special combat maneuvers. You gain the following benefits:

• You learn three additional maneuvers shown below. These don't count against the maneuvers you already prepared. If a maneuver you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice).
  
  Raven Sense. You can spend one superiority die to enhance your senses with the power of raven. Your senses are enhanced for hours equal to the number rolled on the superiority die. Your darkvision range is doubled for the duration. You can also see up to one mile away and discern shapes and details as if they were only 100ft away. Additionaly, your smell and hearing sense is enhanced for the duration, giving you advantage on Perception and Investigation checks and Survival checks made to track a creature.
  Raven's Resolve. If you fail a saving throw made to resist being frightened, you can spend one superiority die to succeed instead. 
  Shadow Step. When you make a weapon attack, you can expend a superiority die and add it to the damage. If this attack hits, a burst of smoke and shadow allows you to move up to 10ft without suffering opportunity attacks.
