[Super] : Summon a shield of Void Light. While Sentinel Shield is active: [Light Attack] : Attack. [Block] : Block. [Grenade] : Perform a Shield Throw. Guard with Sentinel Shield to create a defensive wall that draws hostile fire. Allies behind the shield have increased survivability, weapon damage, and passive reload. Guarding allies and blocking damage makes the shield last longer and increases your Shield Throw damage.
