Sniper's Mark

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.

• 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.
