Dual Blades already move faster than almost anything else in Monster Hunter Wilds. The Boost Bracer coming in the Ascendance expansion pushes that further by bolting an air launch, a directional dash, and a longer-reaching boosted state onto a weapon that was mostly locked to the ground.
Quick answer: Stay aggressive to build Boost Bracer energy, then land the Dual Blades’ Boost Driver to enter Boost. The Boost Driver is also an offset attack, and while boosted your swipes gain extra reach shown as blue energy trails, plus an air launch that chains into a second directional dash.
How Boost activates on Dual Blades
The Boost Bracer is a gauntlet that adds a new set of actions to all 14 weapon types. Energy fills as you keep attacking, and you spend it by triggering Boost with a special Boost Driver attack, or with other weapon-specific actions. Once Boost is active, certain moves are temporarily upgraded until the state runs out and you have to rebuild it.
Dual Blades have a second, lower-commitment route as well. Surging forward with the bracer generates boost charges on its own, so you do not need to land an offset to keep the meter moving. That matters against monsters that give you very few clean openings.
The launch itself is a two-part move. The bracer throws the hunter straight up, and from that airborne position you can fire off a second dash in a chosen direction, which is what turns the boost into repositioning rather than just height.

Boost Driver doubles as an offset attack
The most important detail for Dual Blades is that the Boost Driver is not just a meter dump. It carries offset properties, so throwing it into a monster’s incoming attack both stops the monster and puts you into Boost. That gives the weapon an aggressive, forward-facing answer to attacks it previously had to step around.
You can also break out of a normal combo directly into the offset dash. Instead of finishing a string and eating the follow-up, you cut the combo short, dash through the attack, and keep your position on the monster.

Boosted combos gain reach and steering
While Boost is active, the blades throw out blue energy on their swipes, and that energy is not just decoration. It extends the effective melee range of the attacks, which is a meaningful change for a weapon that normally has to be pressed against a monster’s leg to connect.
Boosted combos also stop being fixed animations. You can adjust which way you are facing and drift slowly forward as the combo runs, so a monster shifting a few steps away no longer wastes the whole string.

Aerial dash options and the spine ride counter
Side by side, the standard dash attack and its boosted version are noticeably different. The boosted one keeps you in the air longer and opens up more follow-ups, so aerial pressure becomes a real option rather than a single hop.
The aerial dash can also be used defensively. Timed into a projectile such as a fireball, it counters the shot and rolls straight into the spinning attack that runs the length of the monster’s spine, ending in a turn-around animation as the hunter comes off the back.

Note: the spine ride is reached through the counter here, not through the Focus Strike conditions Dual Blades use in the base game.
The blades and armor in the showcase
The hunter in the footage is using the La Lavina Dual Blades paired with the Master Rank Zou Wu armor set. Both are cosmetic context rather than mechanics, but they confirm the showcase is running on Master Rank gear rather than base-game equipment.
Release window, platforms, and the remaining weapon breakdowns
Monster Hunter Wilds: Ascendance is a paid expansion due in 2027 on PS5, Xbox Series X|S, and Steam, and it requires the base game to play. No narrower release date has been confirmed.
Capcom is releasing a Boosted Action Breakdown video for each of the 14 weapon types on a daily schedule, starting with Great Sword and continuing through the rest of the roster. Ascendance is also part of Capcom’s Tokyo Game Show plans on September 17th, 2026, with a playable demo at the company’s booth.
If you want to have the base game ready before then, Monster Hunter Wilds is available now on Steam, with a Switch 2 version in development.
The short version: for Dual Blades players is that the weapon is trading none of its speed and gaining reach, air time, and a counter it never had. The offset on the Boost Driver is the piece worth practicing first, since it is both your defensive tool and the fastest way into Boost.
