Storm Damage is a prefix that turns up on Main Hand, Off Hand and Ring. It gives Storm Damage: +3% to +4% at its lowest step, +62% to +84% at its best — and you need item level 116 before the best one can appear at all.
It comes up at weight 6 when the game rolls affixes, never doubles up with another affix that does the same job (affinity_damage), and it is what puts Sparking, Charged, Crackling, Thundering and Tempestuous in an item's name — so you might pick up a Sparking Wand.
9 Uniques lock it to a fixed number: The Divided Sky, The Thunderclap Codex, Petrichor, The Skysplinter Fan, Weathervane and Rumor of Rain and 3 more.
