Conductivity is a spell that curses all targets in a area, making them less resistant to lightning damage and gives lightning damage a chance to shock. Negative Resistances: This curse can cause resistance values to dip into the negative, if the base values are low enough. This will have the effect of increasing the damage above values listed on the character screen. For example, a monster that has 0% lightning resistance and then is inflicted with level 1 Conductivity will take 25% more (multiplicative) lightning damage than the spell or attack would normally cause. Conductivity can be turned into an aura by linking it with either Blasphemy Support or Awakened Blasphemy Support.
