Elemental Weakness

A favorite of Witches and other masters of magic, the Elemental Weakness curse strips away resistances to cold, fire and lightning. Once afflicted by the curse, an enemy will suffer grievous harm from any elemental attack, even if they have natural resistances.

Description on the official Path of Exile website

Elemental Weakness is a spell that curses all targets in an area, making them less resistant to elemental damage.

Skill Functions and Interactions

• Negative Resistances: This curse can cause resistance values to dip into the negative, if the base values are low enough. This will have the affect of increasing the damage above values listed on the character screen. For example, if a monster has 0% elemental resistances by default is inflicted with level 1 Elemental Weakness, that monster now has -20% (negative 20%) elemental resistances. Consequently, the monster thus receives 20% more elemental damage than the spell or attack would normally cause. The curse gets even more effective against monsters with higher resistances.
• The extra damage is multiplicative with other damage modifiers as it is considered to be the monsters damage mitigation, and not due to a buff on any players' elemental skills damage.
• Elemental Weakness can be turned into an aura by linking it with the Blasphemy SupportBlasphemy SupportSupport, Hex, Aura
