Ursadon matriarchs are powerful creatures that lead packs of ursadon.

During the Second Great War, Sarah Kerrigan and her resurgent Swarm hunted these creatures for their essence in order to adapt the Swarm to Kaldir's flash freezes.[1]

Game UnitEdit

Three ursadon matriarchs appear in the Heart of the Swarm mission "Harvest of Screams". They must be killed for the zerg to endure the flash freezes. However, only one is needed to truly endure the flash freeze, the others just increase the visibility and the effects of resistance against the freeze.[1]
