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.   Slashing Bash. If the shadow airship moves at least 20ft straight toward a creature and then hits it with a bash attack on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, the shadow airship can make one attack with its blades against it as a bonus action.
