"Ah, but there exist many sorts of magic in this world.", Taunos said, "My magic is different from everybody's who isn't a shaman, except perhaps druids. Primarily, we have magic drawn from nature, magic derived from runes, and arcane magic drawing from ambient energy. Demonic magics are arcane magics, just very corrupted. Basically, the only way we can know is giving it a try, but if you can draw magical energy from the air around you, you'd best stay on your toes."
"And what about you?", Geralt asked, "You're quite the magic sort yourself, Taunos."
"Yes.", Taunos replied, "Unfortunately, my shamanistic powers won't work against very powerful demons. Not that I'd be useless, meaning no offence to you, Valkyrie."
At that moment, there was a strange, distinctly magical, flowing sound.
"Do you... hear that?", Geralt asked.
"It sounds familiar...", Taunos replied as he tried to think of what it was, "I suspect..."
He pointed roughly in the direction of the sound. There was a
red, clearly demonic beast, with two notable tendrils and very nasty teeth. The tendrils were stuck in a body, which appeared to be shriveled up, as if drained of all energy.
"I suppose that's a demon?", Geralt asked, figuring he knew the answer nonetheless.
"A felhound.", Taunos explained, "Drains magical energies out of mages before simply devouring them. Hardly a dangerous demon, assuming you're not a magic user."
The tendrils dropped the dried up husk of a body, and then the felhound grumbled. It shook a bit, and then, part of it's body split off. The two parts rapidly grew back the missing body parts. Soon enough, there were now two felhounds.
"I've never actually seen them do that before.", Taunos noted.
The two felhounds looked towards the group, and growling was to be heard as others ran over. The pack ran straight for the group. As they approached, Taunos hit one with a lightning bolt, which didn't quite stop it, but Geralt leapt into the fray and stabbed it right in the head. Taunos backed away.
