Storm Front

The  is a Grenade Mod manufactured by Vladof. Storm Front is obtained randomly from any suitable loot source but has an increased chance to drop from Lee, Mike, Dan, or Ralph located in Bloodshot Stronghold.

Special Grenade Effects
Initial explosion spawns a 'fork' which shoots out a few child grenades. The fork creates an aura that shows the range of its electricity can reach (much like teslas). The fork attacks any enemies that wander near it for shock damage. The child grenades also attack enemies near them with a smaller range and slightly less damage. The fork and child grenades explode for additional damage when finished.
