The arrow flies with a sharp whistle before puncturing the beast's back and exploding in a flurry of smoke and flesh. The beast roars, bucking about as its back is torn open. It collapses on its side for a moment, before roaring with rage and getting back onto its feet again, glaring around the street furiously. You have damaged the creature, but not mortally. It seems to be covered in thick, protective blubber. This is gonna be tricky to kill.
