Additionally any creature that tries attacking him while he is in dim light has disadvantage. Finally, Rebelus can make the Dash, Dodge or Disengage action as a Bonus Action.

Slick Design. Rebelus has advantage on getting out of grapple rolls. This also makes Rebelus difficult to hit with opportunity attacks when he uses the dash action.

He can’t make this swap if he or the ally has the incapacitated condition. Additionally, Rebelus has a +5 bonus to initiative, and other creatures don’t gain advantage on attack rolls against you as a result of being unseen by you.
