After Dark Shade hits a character with a melee strike, kill Dark Shade to attach it to the target. While Dark Shade is attached, it is not a character and the target must succeed with a Fortitude save (DC 16) before initiative each turn or suffer one wound. If the save is successful, or the target leaves play, put Dark Shade in the rank behind the last occupied rank in your army and inflict one wound on it.
