Your Glacier, Duskfield, Coldsnap, and Shatter grenades have enhanced functionality. Glacier Grenade: Adds a [Stasis] Stasis crystal and changes the formation. Duskfield Grenade: Increases slow-field size and creates a small [Stasis] Stasis crystal on impact. Coldsnap Grenade: Seekers duplicate after freezing a target and create a [Stasis] Stasis crystal on detonation. Shatter Grenade: Creates additional shrapnel projectiles on detonation. Hitting frozen targets with this grenade refunds some grenade energy.
