Gigasword is a skill that infrequently appears throughout the Dragon Quest series. Similar to Gigaslash and Gigagash, it is an electrically charged sword strike, though it targets only one foe instead of a group.
Note: though Gigasword is listed under the Hero/Heroine's spell list, it is not affected by Bounce.
In the remakes of Dragon Quest V, the Conkuistador will attempt to slay a character with the skill, but it will always fail and fry the faerie.
It's a main skill of the Zenithian Sword in it's regular and alchemized versions.
Gigasword can be learned by Hero Solo at level 38 and costs 111 MP to use. It inflicts 300% potency surehit Zap-type physical damage to all enemies in a fan-shaped area in front of him. Upgrading the ability increases its damage and reduces the amount of MP it costs to use.
