Immobilization wave

Immobilization wave is an psionic power demonstrated by Sarah Kerrigan during the End War. When the aura is activated, Kerrigan unleashes a wave of psionic energy around her, levitating, damaging and stunning all enemies surrounding her for a brief time. This ability was only able to slow larger enemies such as hybrids.

Game Effect
