To be fair, it wasn't that Aurelia's weapon wasn't sharp enough; rather, the Razorback Ravager's oily skin was absurdly thick— more literally than Metaphorically.
Sirius watched with wide eyes as Aurelia dragged her sword across the Ravager's back. The blade eventually slid off due to the slickness of the creature's skin. When she finished, Aurelia quickly turned to observe her amazing handiwork... only to be greeted by disappointment. She'd barely scratched a thin layer of the creature's thin hide, which wasn't thin at all. The bony frame of the Ravager had misled them into thinking its skin would be thinner than it actually was.
But the surprises weren't over. They watched in disbelief as the oil on its back began to converge on the shallow cut, sealing it up.
'Is it... healing?' Sirius thought, astonished. The oil was gradually filling in the wound and mending the flesh together.
