The official GemStone IV encyclopedia.
The lightning elemental is a crackling mass of solidified power, definitely alien to Elanthia. Nearly gelatinous in substance, solid bolts of lightning weave themselves into the skeletal form of some horrible beast, only to arc in an instant to a vaguely humanoid form and then back again.
Striking a lightning elemental with a metallic melee weapon causes the attacker to suffer a highly damaging shock. This can be prevented by either using non-metallic weapon or while under the effect of an elementally balanced core.
See material for a list of materials that are considered metallic.
