Being infant dragon spawns, thus deliberately related to Reyburn, Ghowls populate much of this land's ground, wandering about in groups of two or more. They hardly ever initiate an attack, watching Hunters from a distance. Should you close in to them, they will approach you in an attempt to bite.
However, if they sense that a Hunter becomes reckless in attacking other Hostiles, distant Ghowls will start giving chase, in the intent to surround the Hunter off-guard. On later levels, Ghowls will eventually start spitting fireballs as an alternative attack (they are dragons, after all). However, their huge tendency to stall for an opportune opening makes them small fry targets.
