Thundara Blade (サンダラ剣, Sandara Ken?), also known as Thundara Sword or simply Thundara or Bolt2, is a recurring ability in the series. It is generally a mid-powered Lightning-elemental Spellblade ability, either giving the user the element as long as they don't use another Spellblade ability or outright dealing damage. It generally requires the Thundara spell in order to use it.
Thundara is a level 3 Spellblade ability that costs 5 MP to cast. When used against an enemy that is weak to Lightning-elemental attacks, the power of the user's attack is tripled and pierces the target's defenses.
Thundara Sword is a Sword Magic ability for Steiner while Vivi is in the party, knowing Thundara from Lightning Staff found in Burmecia, the earliest. It costs 12 MP to cast and increases Steiner's attack by 10.
