Partbreaker. Is it reliable for damage, or for speeding up part shattering?

[Hoot Hoot]

Recently me and some mates noticed we been struggling in making sure we broke everything in Kushala and Vaal Hazak, which is why i built some deviljho armour to max out partbreaker.
It stats it increases dmg by 30% to parts, however im unclear if it actually buffs my damage, or speed up the part breaking, as i spent an entire hunt hitting the vaal hazaks face, and only broke the fangs 2-3 mins from ending.
Anyone got the exact data on what it does?

Speeds up part breaking.

The breakeable parts all have a certain amount of health points. Once they're depleted the part breaks. Partbreaker increases the damage you deal to the parts.

It'll occasionally make them flinch/knock them back too if you break them enough. I run it with weakness exploit.

Edit: Stagger is the word I was looking for.

When I play solo with part breaker I keep breaking parts ridiculous quickly. To the point where I don't even need to try.

Now with randoms it's still doing fine and will generally break all parts if you go for them. The others can do whatever they want but you'll most likely break them.

It makes it easier to break parts, but does not changes the amount of damage you dealt or the amount of health a monster has, so you'll still need to pull the same amount of swing to kill your hunt.

That being said, it probably still helps with the fact that breaking part stagger your hunt and allows you to land a few free hits, so I wouldn't say it does "absolutely nothing" in terms of dps.

Thanks for all the replies.

The way I understand it:
Hitting a monster's parts causes damage to the monster's "Total" HP pool and to a separate "Part" HP pool that isnt shown to us. Once you deplete the "Part" health bar, the piece gets cut off or broken.
The partbreaker skill therefore increases the damage to the "Part" HP pool only, but doesnt affect the "Total" amount of damage that is shown to you.

No data, but I use the amulett when i do good investigations solo, works def. better then without that part breaking bonus. I think the parts breaking faster without doing higher damage.

partbreaker is a nice bonus , but i wouldnt sacrifice some other damaging skill for it.

For example my CB build had room for somthing, i coulda used focus 2, guard 2 ..or some other combination, i decided on partbreaker 2 as it really helps smash of horns and such with SAED, as i alreayd had all the other damaging skills i needed for the build.

Partbreaker deals more damage on a seperate scale from that actual HP damage you're dealing to the monster. It does not increase the damage done to the monster as a whole, but it does affect what is essentially a secondary healthbar the parts have, which affect the threshold for when a part breaks.

In other words, let's say an attack does 100 raw damage to the head. If you have Partbreaker, the actual damage will still be 100 to the head (assuming no crits, etc), but the damage the individual part takes in terms of its internal threshold will be 130. You're not doing more damage overall, but you are speeding up the process of breaking individual parts.

In solo play this effect is really obvious, as it makes it hilariously easy to juggle certain monsters (for instance Nergigante). In multiplayer... not so much, as the monster, on top of having 2.6x HP and part-breaking thresholds, is often moving around and switching targets constantly, making it that much harder to get concentrated hits on a specific part.

Some parts like Kushala's head have a special threshold and will only break after the monster has been reduced to 20% so keep that in mind.
For some monster its useless.

Two things going in here.

The first is as said
Part breaker directly increase damage to that part until it break then it does nothing.

If you look in kiranico it actually lists these values. ie. Kirin's horns require that you deal 600 damage to break them. And it has a special rider of only breaking after it's at <30% HP.

The second is the HP scaling in Multiplayer.

In single player you will break parts constantly even without part breaker. Then suddenly in MP even with concentrated effort they just wont break. This is because of the health scale combine with the break HP scaling.
