Xenoblade Chronicles/Prologue

In the beginning of the game, you'll be treated to your first combat controlling Dunban with the Monado while Dickson and Mumkhar supports you.

The best advice is to use to enchant their weapons first followed by a Monado powerful attack.

On new game plus, Dunban will be in its highest experience with the current sword from your first playthrough. Dickson will be in his best clothes and Mumkhar will be in his Mechonis suit. You'll be automatically enchanted first so you won't have to worry about taking forever to knock down the Mechon.
