Vulnerability

Though they generally feared sorcery, even the Marauders came to learn the value of the powerful Vulnerability Curse. Before charging into battle, a caster on the front lines would speak the curse, throwing it far and wide on their assembled enemies. The Marauders would come on with a roar, a tidal wave of rage and steel crashing against their foes. The Vulnerability curse could hardly be seen, but its effects were dire. Blows from the Marauders hit far harder, sundering helm and shield like tin. Those not killed immediately would be stunned inert, unable to defend themselves from the onslaught. Even masters of magic were vulnerable, for the curse corrupted the force of their protective shields.

Description on the official Path of Exile website

Vulnerability is a spell that curses all targets in an area, making them take increased physical damage and granting hits dealt on the cursed targets a chance to apply bleed and maim.
