A ghost mage, approximately level six. The main strength lies in its ability, which is a kind of mind control, and here are more details. Mind control is allowed one-on-one, while the banshee itself is inactive and has a disadvantage in terms of health or armor. The mind control itself does not reduce initiative. Here, we need to think about balancing the number of banshees = the number of puppets +(-) their level. For atmosphere, you can add a banshee's scream and something else, I don't remember, something like incorporeality, in short, like ghosts, and so that there is no imbalance, vulnerability to magic. For the texture, I have an idea to take the hair of dark elves, attach it to a lich, and repaint all of this in dark blue tones.
