Shadow Target. The shadow can only target the victim of its illusion. To its victim, it does not appear as a shadow, but a real, physical being; to others, however, the shadow appears only as a shadow; no discernible features can be made out. Additionally, other shadows and their victims are not detectable by the victim of this shadow, the illusion only ending once all shadows targeting the victim have been defeated.   Pack Tactics. The shadow thug has advantage on an attack roll against a creature if at least one of the thug's allies is within 5ft of the creature and the ally isn't incapacitated.
