The Butterfly Swarm is a Hunter event that happens just South of the Wilderness lodestone, to the West of the obelisk. During the event Magical butterflies and Poisonous butterflies will spawn. Players must catch the Magical ones and hand them in to the nearby demon hunter. Catching Poisonous ones will deal a big hit of poison damage and will not progress your personal goal.
