Dual Blades in Monster Hunter Wilds: Ascendance gain a new resource layer on top of Demon and Archdemon Mode. The Boost Bracer, a Master Rank piece of equipment that applies to all 14 weapon types, gives the weapon a counter it never had, an aerial dodge extension, and a set of enhanced combo finishers.
Quick answer: Spend a Boost Bracer charge with the Boost Driver (R1 + Triangle + Circle on PlayStation, RB + Y + A on Xbox) to dash forward with an attack that offsets a monster’s move, triggers Boost, and fills roughly 70 to 75 percent of the Demon Gauge in one action.
What the Boost Bracer does
The Boost Bracer becomes available as you move into Master Rank. Its energy builds while you keep pressure on a monster, and once you have enough, Boost turns on. Two things happen while Boost is active: certain existing actions are temporarily upgraded, and a handful of moves that do not otherwise exist become available.
Boost Drivers are the fast way in. They are attacks that switch Boost on immediately, so you never have to stop swinging to activate it manually. Each weapon has its own version. Boost Driver use runs on a charge system displayed at the bottom center of the screen, closer to how Wirebugs worked in Monster Hunter Rise than to a single filling bar.
The Boost Driver offset attack
This is the single biggest addition for Dual Blades. Pressing the Boost Driver input consumes a bracer charge and sends the hunter spinning forward at high speed. The move carries offset properties, meaning a correctly timed hit into a monster’s incoming attack knocks it off balance instead of trading damage with it.
The gauge return is the part worth planning around. A single Boost Driver fills roughly 70 to 75 percent of the Demon Gauge, so a weapon that normally has to earn Archdemon Mode through sustained hits can now get most of the way there with one committed move. It also doubles as a gap closer, which matters for a weapon whose damage depends on staying glued to a hitzone.
You can also branch into the Boost Driver in the middle of a Blade Dance. That turns a committed combo into an escape route and a counter at the same time, without dropping back to neutral and losing your position.
Perfect Demon Dodge goes airborne
The standard Perfect Dodge keeps the hunter grounded. With Boost active, the same evade launches you into the air and hands you a second directional air dash on top of it. Dual Blades can reach aerial positioning without a ledge, a slope, or a Focus Mode setup.
From the perfect air dash you can go straight into the Heavenly Blade Dance, which is the weapon’s signature spinning finisher. In practice that means a defensive read converts directly into the biggest attack in the kit rather than a repositioning hop.
Boosted combos and the range change
Blade Dance under Boost is the Empowered Blade Dance. It runs with a faster final animation, added visual effects, and a heavy last hit that carries slight end lag, so it is not free to throw out next to a monster winding up. The Demon Dance gets its own boosted version as well, marked by blue effects rather than the red glow on the empowered Blade Dance.
Separately from Boost, Dual Blades have received an across-the-board increase to melee reach. That is a quiet change with a large effect on a weapon that spends its life inside a monster’s hurtbox, since fewer swings whiff when the target shifts a step away mid-combo.
| Action | What changes with Boost |
|---|---|
| Boost Driver | Forward-dashing offset attack; spends a bracer charge and fills about 70–75% of the Demon Gauge |
| Perfect Demon Dodge | Launches the hunter into the air with a follow-up directional air dash |
| Empowered Blade Dance | Faster final animation, red visual effects, heavy finisher with slight end lag |
| Demon Dance | Boosted variant with blue effects |
| Demon Flurry Rush | Boosted rush that closes distance and transitions into a roundslash |
| Melee range | Increased for Dual Blades attacks generally |
How Dual Blades compare to other weapons
Every weapon receives a Boost Driver, but what Boost unlocks differs sharply. Dual Blades lean toward mobility and counterplay; others get raw output or defensive tools.
| Weapon | Boosted action |
|---|---|
| Great Sword | Running Offset Rising Slash, Boosted Power Clash, Drive Charged Slash, Rising Combo |
| Long Sword | Empowered Iai Spirit Slash |
| Sword and Shield | Charged Chop Extension |
| Dual Blades | Empowered Blade Dance |
| Hammer | Rising Spin Slam |
| Hunting Horn | Sliding Performance |
| Lance | Empowered Finishing Thrust |
| Gunlance | Guard Cross Counter |
| Switch Axe | Empowered Full Release Slash |
| Charge Blade | Empowered SAED |
| Insect Glaive | Offset Sweeping Combo |
| Light Bowgun | Bracer Minigun |
| Heavy Bowgun | Beam Blast |
| Bow | Boost Driver Offset Attack, fourth charge level, Empowered Dragon Piercer |
Note: some moves refund part of the Boost gauge. The Great Sword’s Power Clash is one example, which means a weapon’s economy of charges is not purely a spend-and-wait loop.
Access requirements and release window
You need a copy of Monster Hunter Wilds plus the expansion, and you must have completed the 7★ assignment “Awaking From a Dream” to reach the Ascendance story and Master Rank quests. The expansion is planned for 2027 on PlayStation 5, Xbox Series X|S, and Steam, with cross-play supported. No exact date has been confirmed.
Capcom is releasing a Boosted Action breakdown for each of the 14 weapon types on a daily cadence, with the Great Sword going first and Dual Blades landing third. The Capcom Tokyo Game Show showcase is scheduled for September 17, 2026, which is where the remaining weapon details and any broader expansion news are most likely to surface.
