Synchro Thrusting : bug on damage formula?

Hello world,

this topic is more for Hoplite, but anybody with knowledge is welcome.

I was testing ‘Synchro Thrusting’ and his ‘Synchro Thrusting : Pierce’ attribute, and I found something really strange.

Some information first : ‘Synchro Thrusting’ skill was lvl 1 and ‘Synchro Thrusting : Pierce’ attribute was lvl 5 (max, supposed to give +50% pierce damage and -50% strike damage)

Physical attack : 193 - 206

Also on tooltip of the skill, I can see :

  • spear attack : 181
  • Shield attack : 341

Finally, below the damages test on 2 different monsters, (1) is ‘Synchro Thrusting’ skill alone, (2) is ‘Synchro Thrusting’ skill after ‘spear lunge skill’ (input a vulnerability to pierce)


Pag Sawer

Synchro Thrusting : Pierce - OFF

(1) 228 + 263 = 491

(2) 430 + 447 = 877

Synchro Thrusting : Pierce - ON

(1) 372 + 92 = 464

(2) 706 + 156 = 862


Pag Clamper

Synchro Thrusting : Pierce - OFF

(1) 331 + 427 = 758

(2) 562 + 627 = 1189

Synchro Thrusting : Pierce - ON

(1) 507 + 171 = 678

(2) 870 + 250 = 1120


So, is it normal ? If I’m not wrong, it’s like the skill is just a 2 time pierce attack and the attribute just change the repartition of damages between the 2 hit.

So, making the target weak against pierce and increasing pierce damage of the skill don’t result in a boost of damage :o

Waiting your feedback before posting a bug report

Few more test this morning :


Earth Hallowventer

Synchro Thrusting : Pierce - OFF

(1) 225 + 265 = 480
(2) 444 + 451 = 895

Synchro Thrusting : Pierce - ON

(1) 366 + 94 = 450
(2) 731 + 160 = 891


Earth Deadborn Scap

Synchro Thrusting : Pierce - OFF

(1) 472 + 204 = 676
(2) 693 + 395 = 1088

Synchro Thrusting : Pierce - ON

(1) 757 + 76 = 883
(2) 1100 + 110? = 1210? (Monster die with the first hit)


I will need more data : those numbers are out of logic :o

One last test seem to confirm the skill is not working as expected :


Pag Wheeler

Synchro Thrusting : Pierce - OFF

(1) 315 + 414 = 729
(2) 545 + 607 = 1152

Synchro Thrusting : Pierce - ON

(1) 515 + 157 = 672
(2) 853 + 231 = 1084

So I think I will adress a bug when I will have time.

certain monsters take less dmg from piercing

I know, but even with pierce weakness debuff, targets don’t take more damages in all cases.
To simplify: you can see the final dammages never change when you change the répartition of damages type (pierce and strike).

The expected résult is to gain damages vs pierce weak and strike resist monsters when you setup the attribute to ON, and also gain damages after spear lunge.

Ho, and we also don’t expect to have those increased strike damages after spear lunge: no sense.

And what about the skill description show more base damage for the strike part than the pierce part but at the end it’s the pierce part the stronger (I suspect formula lire this: pierce damages + primary physical attack VS strike damages + secondary physical attack)

Im probably understanding this wrong but it looking like its working as it should to me except for the ‘strike’ part increasing from spear lunge?. I’ve always read that attribute as being a dps loss because you are reducing the scaling part of the skills damage by 50% while increasing the weaker part of the skills damage by 50%?

Its confusing either way.

i think it’s because of the attribute itself. the shield (strike) scales better than the pierce part. you reduce the damage of the strike part reducing the overall damage of synchro
