For example encountering a wolf it might circle you and howl alerting its pack and once injured it would attempt to escape, a minatore might roar trying to intimidate you before charging straight at you with those huge horns and once injure it might flail around trying to kill you, a bear might just look at you and go about his business, a mountain lion might try to stalk you before pouncing, bandits could beg for their lives or become enraged when you plunge your blade into his bandit friend.
