Assassin's Mark

The aura version of Assassin's Mark

"Assassin's Mark, while not terribly strong on its own, gets incredibly effective in the hands of the right player. A character heavily invested in increased Critical Chance and Critical Damage will absolutely decimate their foes when they afflict them with this weakness. While it's not the most direct of curses, Assassin's Mark stands among the best when utilized correctly."

— Description on the official Path of Exile website

Assassin's Mark is a curse that makes enemies more vulnerable to critical strikes.

Skill Functions and Interactions

Increased Critical Chance: The modifier Cursed enemies have an additional x% chance to receive a Critical Strike listed on the gem is additive with your current chance to get a critical strike. If you have a 20% chance to critically strike with an attack or spell, and it hits a monster inflicted with level 1 Assassin's Mark, you will have an an additional 5% chance of the strike being a critical one, for a total of a 25% chance.

The modifier Cursed enemies take x% increased extra damage from Critical Strikes is multiplicative with the characters damage. However, it stacks additively with other increased Damage taken modifiers that the enemy may have, for example shock.
