How does "increase armor piercing" work?

Have a 2 questions regarding this particular stat (see pic, below that 15% chance stat):

  • how does it work if you already have 100% physical to piercing converted, via Nadaan’s constellation?

  • is it possible to have 100% physical to piercing converted, via Nadaan’s constellation for a weapon that has …say … 33% base armor piercing, if that weapon has 100% or more increase armor piercing?

Increased Armor Piercing is a multiplicative modifier for your base Armor Piercing stat on a weapon. So with Blades of Nadaan, a 50% Armor Piercing sword will have 100%. A 33% Sword will have 66%. So on and so forth.

Having more than 100% Armor Piercing is ineffectual, just like having more than 100% Conversion.

That solves the 1st question: that stat is useless on that weapon.

Wouldn’t that 33% sword have 99% if it had 100% from Nadaan + 100% from that stat?

Was eying the possible servitor’s slicer axe that has 40% base piercing armor.

Wouldn’t that 33% sword have 99% if it had 100% from Nadaan + 100% from that stat? Yes

Was eying the possible servitor’s slicer axe that has 40% base piercing armor. Yes if one of your weapons is a sword and you have nadaan

Nadaan requires a sword … facepalm … forgot about that :frowning:

I’m using Chthon’s blademaster pierce shield build, so that theory goes out the window …

Yah, the bane of DW pierce savagery tricksters:undecided:

Just had another idea: if one has this increase armor piercing by 100%, then one doesn’t need Nadaan’s constellation, right? That opens up other possibilities, no?

If you are 1- handed maybe. If you are DW it doesn’t mean your 33% second sword or axe will have 100%.

But the question is why you would avoid nadaan regardless. It has flat pierce and % pierce. Also fits perfectly in the devotion pattern up to unknown soldier,

Also a Mythical Reaver’s claw now in AoM will be better than a Sinister Slicer for pierce cadence 1 handed

I use a shield, so i’m one handed, yes.

Here’s an example of what i was thinking: https://www.grimtools.com/calc/q2mGMg0Z

Can’t seem to find the stoneplate boots so i opted for Mythical Runeguard Greaves instead.

Perhaps one can better use the 6 devotion points in another constellation, instead of Bard’s Harp + dunno if i chose the skill for the constellation properly.

This is my 1st time making a build and, tbh, most of it is copy / pasted from Chthon’s blademaster. Had to make a few changes because i couldn’t choose the boots i wanted.

Yes it’s a great build. But for AoM I do reccomend you try somehting like Myth reaver+nadaan. If you get your hands on some decent Kuba pants too, oh man:D

This is my current build: https://www.grimtools.com/calc/JVl3MMp2

I have both reaver and nadaan, atm. Those are the best pants i got but i still haven’t found stoneplate boots blueprint :frowning:

Nice… For more damage you can try replacing star of deceit with something else like a decent Rylok medal with fighting spirit mod. Replace liifegiver signet with open hand of mercy for reliable % and flat RR. The replace essence of ch’thon with ulgrim’s guile or something

I do have that ring but i can’t replace it just yet for for the same reason i can’t replace the boots: lack of life on the other gear pieces.

I can’t also replace the medal just yet, unless i find another source of chaos res.

Deadly momentum should be maxed!:slight_smile:

Moved from Menhir will and fighting spirit. That dmg from deadly momentum goes a loong way in dealing more damage and stealing more life

Thanks for the heads up!

May I chime in with a probably stupid question?

I know about the normal conversion, but I noticed you’re wearing very little +piering dmg equip. Does pierce conversion apply after +physical dmg?

As far as i know, any flat phys dmg is converted to piercing (dunno which particular grimtools link you’re referring to, as i have posted several in this topic). Add that to the piercing i already have and it’s more then it may seem.

That said, i wasn’t aggressively pushing for dmg because i didn’t have enough res, which forced me to let go of some more dmg oriented affixes / prefixes in some pieces to have said res in them.

Meanwhile, i figured out how to select stoneplate boots and so i changed the build a bit: more dmg oriented now, though i’m still forced to use mythical black star of deceit to make sure all the resistances are over-capped.

I know attack speed is over-capped as well but i chose to have squad tactics with 12 because of the +all dmg and it also maxes my casting speed.

From my fooling around with some prefixes / affixes as well as constellations, i figured Nadaan is definitely needed. This means that 98% increase armor piercing stat on weapon is wasted but 6% reduction to enemy health + increased dmg VS humans / chthonics are much welcome.

Dmg is quite allot higher now, assuming there isn’t any bug with grimtools, due to the attack speed overcap and / or other issues.

I think Naasir is referring to how Warborn (and other pieces such as Grasp of Unchained Might) confers mostly % Physical damage bonuses and not % Pierce.

To answer the question: Armour piercing’s conversion doesn’t change when % bonuses are applied - it is still after, so the % Physical isn’t really helpful.

Considering WB gives so much flat for Deadly momentum and Cadence, nothing beats it

So the +% physical is “wasted”, but the flat dmg is (more than) worth it. Thanks.
