Avan Strash is a recurring sword skill introduced in Dragon Quest: The Adventure of Dai as the signature technique of the hero Avan which he used to defeat Hadlar 15 years before the story begins. It is performed with a unique stance where the wielder's sword is held in the reverse hand and then swung in a wide sweeping motion. The word "strash" is a combination of the words "strike" and "flash".

Avan Strash is the ultimate technique of the Avan-style sword techniques, usable only after mastering the Earth Slash, Wave Slash, and Air Slash. Since Dai's time as one of Avan's pupils was limited, he was only able to learn Earth Slash and Wave Slash from him, but he was later able to learn Air Slash and use the technique in its perfected form.
The technique comes in two variations - the projectile Avan Strash Arrow, and the stronger but slower dash attack Avan Strash Break. Dai later develops a third version, Avan Strash Cross, where he launches an Arrow and then chases it down with a perfectly-timed Break to create an X-shaped impact with five times the power of a standard Strash.
Although the skill itself does not appear in the game, the Luminary will perform the various -splitter skills using the same motion as Avan Strash.
Avan Strash can be learned by Dai at level 80 and costs 72 MP to use. It inflicts 400% potency Zap-type physical damage to all enemies in a range of two squares in front of him. Since it is a Coup de Grâce, it takes 2 turns to charge and can only be used three times per battle. Upgrading the skill increases its damage and reduces the amount of MP it costs to use. Avan Strash's potency can be increased another 50% through Talent Blossoming.
