Sniper's Mark

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

Projectile Weakness is a spell that curses all targets in an area, making them easier to pierce and to knock back. Additionally affected targets take increased damage from projectiles.

Skill Functions and Interactions

• Additional Pierce and Knockback Chance: any projectile type has a higher chance to pierce (additive with other sources of piercing chance) and a chance to cause the target to be knocked away from the player who created the projectile. It does not matter what direction the projectile strikes from, knockback is always away from the player who initiated the spell or attack projectile.

• Projectile Weakness can be turned into an aura by linking it with the .
