This wicked curse alters the very flesh of those afflicted, turning their armor and hide to mere paper. Any projectiles striking a cursed target have a high chance of piercing it, boring straight through to hit additional enemies standing behind. Foes under the Projectile Weakness curse will find themselves frustrated trying to reach the archer, since every volley has a good chance of causing a knockback. A Ranger trained in the curse of Projectile Weakness will be counted amongst the most feared combatants on the battlefield.Description on the official Path of Exile website
