Storm

From Ephinea PSO Wiki

Storm is a lightning damage weapon special. It is the second highest tier of lightning damage specials (3★). Machine-type monsters, with the exception of Epsilon, Vol Opt, and Vol Opt ver. 2, have a chance to be Shock.pngShocked by lightning damage specials.

Common weapons

The chance of obtaining specials on common weapons depends on area and difficulty. When a common weapon drops in an untekked state, there is a chance for it to come with Storm as a special. Storm can also be obtained by tekking up or down a common weapon that drops with the Thunder or Tempest special. Once a weapon drops in an untekked state, the table below lists the overall chance of it coming with the Storm special (including the ability to tekk up or down from Thunder and Tempest).
