From Rudyard Kipling's "The Jungle Book", Bagheera stalks his prey, shedding shadows through the ochre forest. I'll be upfront and say that drawing animals is a weakness of mine (specifically horses, that's a big one haha) but I had this idea of him stalking about and bits/flecks of shadows begin to shed off of his body as he makes his way about.
It'd be fun, leaving wispy trails of shadows as you storm off to battle You come to a halt and the shadows start to engulf you and the beast and the only thing that can be seen are the glowing fiery eyes haha
Absolutely! And it can cover your own men. With proper training they could become accustomed to the beast's trail, maybe create tactics, and it can be used in battle as a defensive measure or used for an offensive attack.
