Ursadon matriarchs are powerful creatures that lead packs of ursadon.
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.
The ursadon charges towards nearby enemies. Can be set to autocast.
- Ursadon matriarchs were previously referred to as yeti matriarchs. In the Galaxy Map Editor, their model is referred to as "Yeti Momma."
