inb4 you close this page and laugh at “lol +3 attack”, please read on.

Here’s a video version of this attack boost guide – which is a little less intense, and may answer your questions before you go down the rabbit hole.
I realize there are a few “video types” out there…

Attack Boost – FAQ & Mechanics

How much Attack/Damage does Attack Boost Give? Does Attack Boost scale differently per weapon? Yes. It differs per weapon. Here’s a chart of how it affect EACH WEAPON on EVERY LEVEL.

Attack Boost on L1 L2 L3 L4 L5 L6 L7 Total Avg
Hammer 16 15 16 15 16 15 16 109 15.6
Greatsword 14 15 14 15 14 14 15 101 14.4
Hunting Horn 13 12 13 12 13 13 12 88 12.6
Charge Blade 13 12 13 12 13 13 12 76 12.6
Switch Axe 11 10 11 10 11 10 11 74 10.6
Longsword 10 10 10 10 10 10 10 70 10.0
Insect Glaive 9 10 9 9 10 9 9 65 9.3
Gunlance 7 7 7 7 7 6 7 48 6.9
Lance 7 7 7 7 7 6 7 48 6.9
Heavy Bowgun 5 4 5 4 5 4 5 32 4.6
Sword and Shield 4 4 5 4 4 4 4 29 4.1
Dual Blades 4 4 5 4 4 4 4 29 4.1
Light Bowgun 4 4 4 4 4 3 4 27 3.9
Bow 4 3 4 3 4 4 3 25 3.6

I tested this manually on every weapon adding one point at a time.

First of all – IT GIVES A DIFFERENT AMOUNT PER POINT PER WEAPON – as you can easily see in the averages on the rightmost column.

There are also (ultimately irrelevant) DISCREPANCIES PER LEVEL ON SOME WEAPONS. I don’t know how or why this happens – but there it is. Notably, check out the Lance and Gunlance growth… It gets 1 less point at the 6th level of Attack Boost…

Does Attack Boost factor in the percentile growth of the Elementless Jewel (Non-elemental Boost armor skill / Set Bonus)? Does it compound? A definitive NO. Look at the chart below for my tests.

First of all, we can assume (and I’ve done SOME testing) that Elementless / Non-Elemental Boost adds ROUGHLY 10% ATTACK, rounded to the nearest whole number “for the most part”.

Weapon Raw Final Gains N Gains %
Axe of Demons Raw 805
Axe of Demons + Attack Boost 7 805 879
Axe of Demons + Elementless 805 886 81 10.06
Axe of Demons + Attack Boost 7 + Elementless 879 959 80 9.10
Axe of Demons + Attack Boost 1 805 816
Axe of Demons + Attack Boost 1 + Elementless 816 896 80 9.80
Iron Bow I Raw 96
Iron Bow I + Attack Boost 7 96 121
Iron Bow I + Elementless 96 106 10 10.42
Iron Bow I aw + Attack Boost 7 + Elementless 121 131 10 8.26
Iron Bow I + Attack Boost 1 96 100
Iron Bow I + Attack Boost 1 + Elementless 100 109 9 9.00

So what does this table tell us? No matter the attack boost, the flat gained amount is “very similar”. Meaning that, if attack boost really mattered then we would definitely see a large numeric gain applied after the percentile growth of Elementless.

FURTHERMORE – look at the gains % column. RAW+ELEMENTLESS came close to 10% every time. If attack boost compounded with it, then we would see an increased percentile growth – which NEVER HAPPENED. When comparing AB+7 and AB+1 percentile growth – the +1 results were far closer (and as expected, a little less) than raw!

How much DPS increase should I expect from attack boost? Okay this will be a vast simplification, but there is a way to determine this “roughly”. Don’t come with the pitchforks because as I already stated – this is an oversimplification of how Attack Boost works with actual DPS.

Weapon Raw Attack Boost + Final DMG Gain %
Axe of Demons 805 0 805
Axe of Demons 805 1 816 1.37
Axe of Demons 805 7 879 9.19
Per AB? 1.31
Weapon Raw Attack Boost + Final DMG Gain %
Iron Bow I 96 0 96
Iron Bow I 96 1 100 4.17
Iron Bow I 96 7 121 26.04
Per AB? 3.72

So, how to understand this table? The rightmost column is the percentile increase in attack – which should (simply) correspond to final percentile increase in DPS.

In the case of the Axe of Demons – each point gives roughly 1.3% increase in attack. Since it has such a high raw damage, naturally, the gains from attack boost are DILUTED.

Look at the Iron Bow I – each point gives roughly 3.7% increase in attack. Why? Because its base damage is bad – each flat bonus to attack is a large percentile growth.


It just means there is a lot more to think about than “Best attack damage wins”. You must calculate the full stack to see the bigger picture. Negative affinity? Rarity reducing the amount of augmentations? I have a spreadsheet for this – but I’m not confident releasing it yet.

But I digress. Ultimately, the question I want answered in this chunk is How much does attack boost increase my actual DPS? – and the answer isthe larger base attack you have, the lesser amount of actual DPS increase you’ll get.

Attack Boost – Summary & Discussion

First of all, attack boost is a great skill which any build would benefit from at least 4 points of. The tacked on affinity +5% is too good to pass up. In anything but the absolute endgame, AB4 is a huge boost.

“Attack Boost 4 is amazing”

AB suffers from a “bell curve”. It’s great in the early and mid-game, then takes a NOSEDIVE in PRIORITY as you’re trying to get your KEY SKILLS FOR YOUR BUILD. Then, after your key skills are setup – you can fill the blanks with more attack boost!

If you play FULLY BUFFED, Attack Boost (and other Flat bonuses to attack) become diluted and you may be better off looking for DPS elsewhere.

Given the large amount of sources for attack – we often consider other “GOD TIER” skills before adding Attack Boost on MOST BUILDS. Hell, people forget about sharpness related boosts.

Ultimately DPS isn’t so simple. Hell, even defensive skills like Earplugs have a “theoretical offensive increase”, much like Evade Extender (higher monster uptime, lesser hits from certain bosses).

But since we’re just talking about Attack Boost

  • Attack Boost is a great skill, but often passed up for more critical ones.
  • Some builds / weapons value Attack Boost more (Will continue research).
  • Almost everyone would be happy Attack Boost +4.
  • Points 5 to 7 are debatable.
  • It’s a great general purpose skill that’s consistent and never terrible.
  • GODLIKE in the early game, all the way up to “pre-endgame”.

Trust me, there’s a lot more to DPS and I can’t possibly mention it all on this guide, which focuses purely on the Attack Boost Skill – but hopefully coming here reduced your questions regarding it and it alone.

  1. I think the discrepancy you are seeing in the gain of attack per level is because of the weapon modifiers being rounded. For example the insect glaive has a modifier of 3.1; so a gain of 3 true attack is 9.3, rounded down to 9. While a gain of 6 is 18.6 rounded up to 19 (-9 for first level = 10).

    • Yeah, I also found out about the hidden modifiers. It’s really unintuitive ey? Attack Boost listing true attack is pretty funny. Either way one of the purposes of this guide is to let people know Attack Boost isn’t as “bad” as they assume since adding a meast 3 attack to 1000 feelsbadman.

  2. Have you gotten around to finding out the values of the charge blade yet? I would do it myself, but I do not have access to lv7 in this skill as of yet and am creating a guide to help my clan compare weapons of different classes (i.e. is this particular greatsword better than this dual blade?).
