Lightning, like with Fire, is one of the most useful spells to have set. When cast, Thunder will always strike it’s target and at higher ranks, will extend it to a small area around itself. Nearly every mechanical enemy in the game, of which there are many, are weak to Thunder making this a mainstay of any spellcaster.
