Assassin's Mark is a curse that causes targets to become more vulnerable to critical strikes. When killed, affected enemies grant life and mana recovery, and have a chance to grant a power charge.

Skill functions and interactions

• Cursed enemies take x% increased extra damage from Critical Strikes: This stat is multiplicative with the extra damage from a critical strike, i.e. the base damage (prior to applying Critical Strike Multiplier) will not be affected. "Extra" damage comes from a critical strike multiplier over 100%. As a result characters with 100% critical strike multiplier (e.g. from Elemental Overload)) will not deal any extra damage. Like other stats it's additive with itself from other sources such as the of Toughness map suffix modifier.

Version history

Version	Changes

Hits against cursed enemies have +1.5% critical strike chance at level 1 (from 5%), up to +2.4% critical strike chance at level 20 (from 9%). Note that this chance now scales with increases to critical strike chance, whereas previously they did not.
2.6.0	Increased Area of Effect mod and doubled its progression per level.
2.0.0	Mana cost reduced at all levels. Area of effect increases per gem level reduced, but the base area of effect has been increased by 37.5% (from 16 to 22). Normalised the increased duration per gem level.
1.2.0	Renamed to Assassin's Mark, previously Critical Weakness. The 'more critical damage' has been heavily reduced. Now grants a chance to gain a power charge on kill.
1.0.0	The bonus to Critical Multiplier has been reduced by a flat 20% at all levels.
0.10.7	Fixed a bug where the additional critical damage applied by Critical Weakness didn't work correctly.

0.9.2	Critical Weakness has been added to the game.
