Added Lightning Damage Support is a Support gem that grants additional Lightning damage to hits made with the linked skill. For instance: the lightning damage will be added to hits made by any Attack or Spell that hits, or hits made by things such as the area damage explosions from Fireball , Detonate Dead, or Minion Instability.
No lightning damage will be added to damage that is not part of a "hit", such as damage over time effects. The lightning damage will however be added to the weapon hits from Puncture, Caustic Arrow, Viper Strike, and any other skill that hits.
