Monster Hunter Wilds Charge Blade: AED Out-Damages SAED in These 3 Situations (Phial Math)

Verified on version 1.020.02 (Title Update 2). Values may change with future patches.

Every Charge Blade guide says the same thing: SAED is your nuke—dump all five phials when the monster trips. That framing is mostly correct, but it skips a calculation that costs real DPS.

Title Update 2 (patch 1.020) added a chain mechanic that makes SAED-from-AED dramatically stronger than direct SAED. But here’s what most guides miss: when you can’t execute that chain, direct SAED is actually weaker than sustained AED spam. The motion value math confirms it, and there are three specific hunt scenarios where AED is the right call—regardless of what your phial stockpile looks like.

This guide covers the phial MV data behind both moves, the conditions where AED wins, and a decision framework you can apply mid-hunt without stopping to calculate.

Phial Fundamentals: Quick Start

If you’re fuzzy on the basics, run through this before the math section:

1. Attack in Sword Mode to build Sword Energy
2. Press Guard + Triangle (PS) or Guard + Y (Xbox) to bank energy as phials — three at a time
3. Load again while phials are already banked to overcharge — yellow gauge indicates 3 phials stored, red indicates 5
4. Overcharged phials deal more damage when consumed in Axe Mode
5. Activate Element Boost (hold Triangle/Y after charging) to power up axe attacks — required for full AED and SAED damage
6. In Axe Mode, AED fires one phial explosion per use; SAED fires all remaining phials at once
7. Phial explosions are not affected by monster hitzones — they deal consistent damage to any part you hit

Impact Phials vs Element Phials

The two phial types behave differently enough that the AED vs SAED calculation differs between them.

Impact Phials deal raw explosive damage and build KO and Exhaust status. They scale with Attack and are boosted by the Artillery skill. SAED fires impact phial explosions in a straight line from the axe swing. Impact phials are the better call against monsters with no exploitable elemental weakness, or any hunt where stunning the monster gives you a meaningful opening.

Element Phials deal elemental damage. They scale with element-matching attack skills—Fire Attack for fire phials, Thunder Attack for thunder, and so on—and are unaffected by Artillery. SAED deploys element phials in a cone pattern rather than a straight line. Against a monster with a strong elemental weakness, element phials can pull ahead in total damage because phial explosions ignore hitzones and apply the full elemental hit regardless of where they land.

For a deeper look at elemental damage scaling in Wilds, our elemental damage guide covers how element attack skills stack with phial output.

What Title Update 2 Changed (The Numbers)

Before TU2, SAED was genuinely struggling to compete with Savage Axe. The patch made three changes that matter for this guide:

• AED and SAED raw damage increased across the board
• SAED chained immediately from AED or AED2 receives a larger damage bonus than direct SAED
• Power Axe multi-hit damage was decreased—a direct nerf to the Savage Axe playstyle

Community datamine analysis from mhchargeblade.net puts the post-TU2 phial motion values as follows:

Motion values are community-researched from datamined game files. Capcom has not published these figures officially.

Two things stand out. First, AED received a proportionally larger buff (+33%) than direct SAED (+22%)—the gap between them narrowed. Second, the chained SAED mechanic is new: execute AED or AED2, then immediately transition into SAED, and each phial explosion jumps from 28 MV to 38 MV. That’s a 65% increase over pre-TU2 SAED and the strongest phial output the weapon can produce.

The chain bonus is what makes the move worth building around—but it also creates a situation where direct SAED (28 MV per phial) falls below what AED spam delivers.

The Phial Efficiency Calculation

Here’s the math that most guides skip.

In Wilds, AED and AED2 each cost half a phial—a change from previous Monster Hunter games where each AED cost one full phial. SAED still consumes all remaining phials at once.

With a full 5-phial overcharged bank, post-TU2:

The hierarchy: Chained SAED (190) > AED spam (160) > Direct SAED (140).

AED spam beats unoptimized direct SAED by 14% in raw phial output. The chained SAED is still the ceiling—but it requires a setup window long enough to complete both animations. When that window doesn’t exist, the calculation flips against SAED.

This doesn’t account for SAED’s axe-hit component, which adds weapon MV on top of phial damage. In practice, the real-world gap is somewhat smaller. But the phial damage difference alone is large enough to matter over a full hunt, especially when you factor in SAED’s long recovery animation.

Situation 1: Fast and Aggressive Monsters

SAED has a long recovery animation. Against monsters that move constantly—Nargacuga, Lala Barina, the smaller, faster targets across the Windward Plains—that recovery window is long enough for the monster to reposition. A SAED that commits mid-movement and hits empty ground isn’t 140 MV. It’s zero, plus however much damage you take during the recovery frames.

AED recovery is substantially shorter. More importantly, each individual AED hit can be re-aimed between uses. Against a fast monster, spamming AED gives you ten repositionable hits from the same phial bank. Ten hits at 16 MV that all land beats five hits at 28 MV when two or three whiff entirely.

The practical decision point: if a monster’s average opening is shorter than SAED’s full animation, AED spam is the higher-EV play. Save phials for a better window and execute the chain when a knockdown or a longer stagger creates the time.

Situation 2: KO Farming with Impact Phials

Impact phials build KO status against monster heads. When you’re specifically trying to stun a monster, the number of phial explosions that actually connect with the head matters more than total phial MV.

SAED’s impact phial pattern fires in a straight line from the axe swing. Against large monsters where the head is above your standard swing height, the straight-line blast hits chest or leg hitzones instead—dealing damage but contributing zero KO buildup. You lose the status value even while landing the explosions.

AED lets you redirect each hit independently. With Wilds’ 180-degree axe swing range in Focus Mode, you can angle individual AED hits at the head on each separate use. Against a monster with a 200+ KO threshold, landing eight out of ten AED blasts on the head outperforms landing three out of five SAED explosions on the head, even though SAED’s per-hit MV is higher.

If a hunt relies on KO stuns for free damage windows—particularly against monsters like Jin Dahaad or Arkveld where stunning creates the best SAED opportunities—the KO cycling efficiency of AED spam can set up more total chained SAEDs across a hunt than SAED-first play.

Situation 3: Short Openings Without Chain Time

The AED to SAED chain requires executing two specific attacks in sequence. Against monsters that grant short stagger windows—a 2-second stumble from a wound, a partial trip from a clip shot—there isn’t always time to queue both animations before the monster recovers.

That leaves two choices: a direct SAED (140 phial MV, all 5 phials spent) or AED spam within the available window (16 MV per hit, 0.5 phials each).

If the opening is only long enough for 2–3 AEDs, that’s 32–48 phial MV at a cost of 1–1.5 phials—less total damage than SAED, but you’ve preserved 3.5+ phials for the next opening. If a longer window appears 15 seconds later, you now have enough phials to execute the full chain and reach the 190 MV ceiling. Gambling all 5 phials on a marginal SAED window and whiffing the recovery leaves you empty for that better opportunity.

Phial preservation against monsters with irregular opening patterns is one of the less-discussed advantages of defaulting to AED during suboptimal windows.

When SAED Is Still the Correct Call

To be direct: the chained SAED remains the Charge Blade’s highest single-burst output. Three situations where it’s unambiguously correct:

• Full knockdowns and trips — 5–10 seconds of stationary monster gives you full time to complete the AED → SAED chain. This is where the weapon’s 190 MV ceiling gets realized. Against Jin Dahaad, Zoh Shia, and AT Arkveld, these windows are reliable enough to build an entire rotation around.
• Trap-locked situations — Shock Trap or Pitfall Trap creates a guaranteed standing window. Chaining into SAED from a trapped monster with a full 5-phial overcharge is the weapon’s peak damage scenario.
• Large slow monsters with predictable patterns — When a monster has long roar animations, slow turnarounds, or reliable recovery periods after attacks, SAED recovery frames are covered by the monster’s own animation. The commitment cost drops to near zero.

For a full breakdown of build options that optimize for chained SAED damage, the Charge Blade build guide covers skill priorities for both phial types after TU2.

FAQ

Does Artillery work with Element Phials?
No. Artillery only boosts Impact Phial explosions. Element Phials are boosted by element-matching attack skills (Fire Attack, Thunder Attack, etc.). Slotting Artillery on an element phial build wastes decoration space with no output gain.

Should I always chain AED into SAED?
Against stationary or slow monsters with clear openings: yes, the chain bonus (38 vs 28 MV) is too large to pass up. Against fast monsters or in short stagger windows: no—use AED spam to preserve phials for a better SAED window later.

Does AED2 trigger the SAED chain bonus?
Yes. AED2 (Amped Element Discharge Follow-Up) also costs 0.5 phials and can trigger the SAED chain bonus if you transition immediately into SAED after it. In sustained combos, mixing AED and AED2 keeps the chain option open while extending the axe loop.

Is Savage Axe still better overall?
Post-TU2, the gap narrowed. Savage Axe was nerfed (Power Axe multi-hit MV decreased) while SAED and AED were both buffed. Community testing suggests Savage Axe still edges pure SAED spam in sustained DPS against stationary targets, but the margin is small enough that execution reliability and phial type matter more than the theoretical maximum for most players.
