Though I sugest people actually roleplay healing a shadow with healing kits... bandages on a shadow? I think not
If you're a shadow dancer you can do many things with shadows, not only summon them, you can make small illusions made of shadows, and I suppose you can also make shadow bandages, or shadow patches to your shadow
Of course that if no one else wants to do this... well it's your rp
Clerical healing hurts the shadows (not sure about the epic one), and they can be turned (but at least before the new script, when you told them to follow you, or attack, they would, for a short period).
