More useful and appropriate abilities – even the bone dragon in the fourth game had a fear attack – or in the fifth game, do everyone consider skeletons commonplace and no one is scared of them, unlike nightmares?))) An attack that causes fear, followed by phasing for the spectral dragon – otherwise, they wrote in the unit description that it exists, and then they decided to change their minds, making the ghosts useless(((( Verdict – give them a fear attack and phasing! And it would also be good to improve their health and damage))
