[edit] Acquisition

This skill is great against enemies with high armor that deal AoE damage, like Wurms and Elementalist Bosses.
Damage dealt to the hexed foe is calculated before damage reduction effects such as Protective Spirit.
It triggers multiple times if the hexed foe hits multiple targets. For each creature that is hit, Pain Inverter produces a separate packet of damage. As each packet is limited separately by the maximum damage of 80, it is hugely effective against high-damage AoE spells, such as Searing Flames and Earthquake.
It is also very effective against damage over time spells, such as Searing Heat and Fire Storm, as the effect described in the previous note takes effect every time the damage pulses.
Does not work against damage dealt by passive skills like Empathy and Backfire. It does, however, work on Visions of Regret.
Does work against damage by retaliation skills, like Whirling Defense, Retribution or Holy Wrath.
Increasing the number of allies is also a good way to take advantage of this spell against AoE skills, like bringing minions, spirits, Asura Summons, Summoning Stones and/or animal companions.
This skill's base damage is capped at 80, not its net damage. As such, skills like Intensity, "By Ural's Hammer!" and Frenzy can cause the damage to exceed 80.
