Demonic Shield is a power featured in The Darkness II.
The power is located in the executions skill tree and is activated by pressing 4 (default on PC) after grabbing an enemy. Once unlocked, it spawns a shield out of the Darkness, which acts exactly like the shields carried by the shielded brotherhood members. The shields hit points can also be increased by upgrading the power. Also, just like ordinary shields, the demonic shield can be thrown at enemies.
