The Slow Field Dispenser is a tower in Sanctum 2 that produces permanent slow field mines, which can be deployed by the player. A level 1 Dispenser creates one mine, a level 2 creates two, and level 3 creates three. The mines do not regenerate and stay where they are placed for all waves.
When a slow field mine is placed, it creates a slow field which appears as sparkly white stars in a dome-shaped area centered on the mine. Both enemy and friendly units within this area will have their actions slowed, including attacks and sound effects. This field makes hitting ground-based enemies' weakspots easier. Reloading while inside one of these areas takes longer than normal.
