The Insect Glaive in Monster Hunter Wilds: Ascendance keeps its familiar shape and gains a second gear. Once the Boost Bracer is active, the weapon’s existing attacks pick up extra hits, extra effects, and extra extract collection, and a new offset attack lets you punish a monster mid-swing without dropping out of your combo. Here is what changes, move by move.
Quick answer: Build Boost energy by keeping up sustained attacks on a monster, trigger Boost with the Boost Driver, then use the boosted versions of Descending Slash, Kinsect: Harvest Extract, Strong Descending Thrust, Tornado Slash, and the new upward thrust launcher to chain damage while marking the target and collecting extracts.
How to unlock and activate Boosted Actions on the Insect Glaive
The Boost Bracer is a Master Rank tool, so it becomes available as you progress into the expansion’s new rank rather than something you can equip immediately. It powers up through pressure. Keep landing attacks on a monster and the bracer’s energy fills; stop attacking and you stall.
With enough energy stored, you activate Boost through the Boost Driver attack or through the specific activation actions each weapon gets. All 14 weapon types share the bracer but not the results — every weapon has its own set of Boosted Actions, and the Insect Glaive’s set is built around acrobatic multi-hit strings, a faster Kinsect, and new offset timing.
Note: the boosted state is easy to confirm visually. Boosted attacks carry heavier hit effects and land noticeably more hits than their standard versions, which is the clearest sign the bracer is live.
Boost Driver offset: counter, topple, and harvest in one move
The headline addition is a sweeping Boost Driver combo that doubles as an Offset Attack. Time it into an incoming monster attack and it counters, staggering the monster out of its animation the way other offset attacks do. What makes it different from the Insect Glaive’s existing Descending Slash offset is the payoff — landing it also collects extracts, so a successful read refills your buffs instead of costing you a Kinsect trip.
Every boosted Insect Glaive attack and what it adds
Rather than handing the weapon a separate moveset, Boost upgrades attacks you already use. The differences show up as added hits, added reach in the animation, and extra utility layered onto moves that previously only dealt damage.
| Boosted action | What changes |
|---|---|
| Sweeping Offset Combo (Boost Driver) | A sweeping Boost Driver combo that functions as an Offset Attack and collects extracts when it connects. |
| Boosted Descending Slash | The standard Descending Slash gains stronger hit effects and additional hits. |
| Boosted Kinsect: Harvest Extract | The Kinsect launches faster, deals more damage, lands more hits, and leaves powder behind. |
| Boosted Strong Descending Thrust | Chains directly into the boosted Tornado Slash without a pause between them. |
| Boosted Tornado Slash | Becomes a multi-hit finisher for the descending thrust chain. |
| Boosted upward thrust | A new launcher that thrusts up through the monster to start an airborne string. |
| Marking and dust during combos | Boosted combos can mark the target and release dust mid-string, without stopping to command the Kinsect. |
The Kinsect upgrade is the one that changes moment-to-moment play the most. A faster launch means less dead time waiting for extracts to come back, and the powder it leaves turns a routine harvest into an additional damage source.
The boosted combo loop: how the new moves chain
The point of the boosted set is that the pieces connect. A Boosted Strong Descending Thrust flows straight into a multi-hit Boosted Tornado Slash with no reset in between, and the offset, the Kinsect harvest, and the tornado finisher can be strung together as one continuous sequence instead of three separate commitments.
On the ground, a standard attack string can apply Kinsect marks as it goes and finish with a Rising Slash that carries you into the air, which keeps the aerial half of the weapon in play without forcing a separate vault input. The new upward thrust does the same job more aggressively, punching up through the monster to open an airborne combo.
What Boost means for extract uptime
Extract management has always been the Insect Glaive’s tax. Red allows charged attacks, white raises movement speed and jump height, orange grants Flinch Free, and holding all three pushes attack higher while mitigating wind pressure, tremors, and roars. Green is separate and restores health.
Boost attacks that of two ways. The offset gathers extracts as part of a defensive read, and boosted combos mark the target and drop dust on their own. Both mean fewer moments where you break off from a monster purely to top up buffs, which is the practical reason the weapon looks more grounded and continuous in the expansion footage.
The pre-existing extract tools still apply. Focus Thrust: Leaping Strike returns red, white, and orange in one hit, and Rising Spiral Slash remains the all-extract finisher that regathers extracts on impact depending on where you land it.
Monster Hunter Wilds: Ascendance release and platforms
Monster Hunter Wilds: Ascendance is due out in 2027 for PlayStation 5, Xbox Series X|S, and PC via Steam. No narrower release window has been confirmed. The base game is already available on those platforms, and a Switch 2 version is scheduled for December 4, 2026.
The weapon breakdown trailer shows the full boosted set in motion, including the Seregios Master Rank armor, Insect Glaive, and Kinsect used throughout the demonstration.
Taken together, the Boost Bracer does not turn the Insect Glaive into a different weapon so much as it removes the pauses. Offsetting, harvesting, marking, and finishing all live inside the same string now, and the reward for staying aggressive is a moveset that keeps feeding itself.
