Note - I have yet to get myself a version of DG, this is based a lot on my experience with DotA. But it seems like it works in generally the same way.
I enjoy creating heroes and such, so I just had to make one for this game 
I won't use exact damage and stuff though.
Should be the right forum, but I often make mistakes.

Story
In the fourth year of the Hadra clan, under the light of a full moon, Nakar was born. Like all other moonborn, he was promoted to a Shaman, and trained with the grace of the nature. Nakar showed himself as an exceptional child, and was a quick learner. His bond to nature was one of his most amusing abilities, and he could spend all the night talking to the animals, which he would later report to his mom, who found them as cute stories.
As he grew up, the clan earned more and more respect. His mere presence could swing the results of a battle, and no member died under his watch. Even if he would come too late, his healing abilities would give them the chance to see sunset once more. As battles waged, the clan became greater, and the envy of other Shamans with it. Yet again under a full moon, what once started would once again end. Using unknown magic from a book found in a Witch they once defeated, a curse was cast on Nekar. After a few agonizing screams, and surrounded in a black aura, he would flee out of sight, away from life.
When the moon left the sky, Hadra was gone. All the sun could see was the bodies of dead, spread across what once was an oasis, now a wasteland. The village was burning, and no witnesses. The only one who eyed it was a lone Shaman, but his sanity has left him long since.
Appearance
Soulbane's shape has changed a lot over time. His once known human shape is now just a silhouette, where his skin is covered in dark purple fur, and his back severely crooked. The rest of him has gotten traits from wolves. His face covered in teeth, and hands with massive claws, he brings the end to anyone close. Staring into his purple eyes will be your last glimpse of beauty before you’re torn apart, either by fist, maws or a decimating tail swing. And while his size is nothing too much, his agility and ferocity makes up for that easily. He has nothing to care about, no emotions, he is just a furball of insanity.

If there is anything off, please do tell. I'll try to edit any mistakes I see.
I have tried to create some synergy between the abilities, and have some uniqueness. He might serve a close to same purpose as Unclean Beast, but I still think his playstyle is unique enough. Finding abilities never useed before is hard though, so Fury is currently the only one I have yet to see in a game. Hope I put it in a more readable format and not just a lot of dry facts.
Hope you enjoy
