Well, relic/mythic bonus was already separate in my spreadsheet, as we already knew it was calculated as a separate step, so no worries there.
However how does "augment: ws dmg+" differ from the augmented Moogle head? Is an augmented Shura head with "Weaponskill damage +2%" different from the Moogle head with "Increases weapon skill damage (+2%)"? That would be extremely annoying.
Diasetsu already tested Kabuto and it didn't apply to additional hits, I think what they are trying to say is this:
WS+ applies to all hits if it is a Relic/Mythic WS
WS+ applies to all hits if it is a Magian WSD+ weapon
WS+ gear only applies to first hit
They could also have been talking about Backhand Blow damage+30%, Cyclone damage+30%, or those other magian weapons/augmented chest weapons.
I never had any conclusive evidence either way with shura head. Was just unlikely that it applied to extra hits after my testing. I never broke the threshold high or low either way, so it could apply and I just stopped because 3% is an annoyingly low number to deal with.
Weaponskill Damage+ could include whole weaponskills while....
Increases Weaponskill Damage may only be 1st hit, much like gorgets and such say Increase Weaponskill accuracy and Damage
I may or may not get around to further testing kabuto before someone else does. I haven't been playing much lately as it's in the 80s and sunny, and the game is crapola at the moment. Can probably do low end test, which I never attempted @ 1.25 pDif pretty easily.
Tested to see if Shura Kabuto +1's WS Damage+3% was any different. Used Greater Colibri to do low end damage as NIN/DNC bare fisted using Shoulder Tackle.
323 skill, 421 attack, 89 vit(Shoulder Tackle is 30%VIT)
38 Damage+8fStr+22WSC=68WSD
Estimated Low Punch: 46
Observed Low Punch: 46
Estimated Low if 3% doesn't apply to the second hit: 138
Estimated Low if 3% does apply to the second hit: 140
Observed Low: 139
Shura Kabuto definitely only applies to 1st Hit. Additionally Anwig doesn't say "Increases Weaponskill Damage +2%" even though that's what it says when you select augments. It just says "Weapon skill damage +2%" same way kabuto does, so this was probably a pointless test.
Not pointless; it means we don't have some bizarre doubt hanging over it. Thanks for the confirmation.
Should amend your post with "does/doesn't apply to the second hit", for clarity.
Tested Overwhelm using 300TP tachi:enpi with brew a 21dmg gkt, SAM/BLM
21+10fSTR+254WSC=285WSD
Maximum Damage of Enpi's main hit with 19% overwhelm bonus= floor(floor(floor(2*285)*2.75625)*1.19)= 1869
Maximum Damage of Enpi's second hit if overhwelm doesn't apply= floor(285*2.75625)= 785
Maximum Damage of Enpi's second hit if overwhelm does apply= floor(floor(285*2.75625)*1.19)= 934
If overwhelm does not apply to the second hit of Enpi, damage high = 2654
If overwhelm applies to the second hit of Enpi, damage high = 2803
Observed High: 2708 (31st WS) was gonna switch to a low-end test @50 and honestly expected I would have seen the 2654 threshold hit earlier than 31 Weaponskills.
Conclusion: Overwhelm applies to all hits of a WS
Um but atonement can't have a 2nd hit...
offhand
Offhand aside, "Delivers a twofold attack. Damage varies with TP.
Burtgang: Aftermath effect varies with TP."
https://www.bg-wiki.com/bg/Atonement
Although, who knows if it wsdmg gear works the same with a weird ws like atonement.
Never knew Atonement was a 2hit WS as I don't even have PLD unlocked. Jumped on test server too unlock, give myself a lvl 75 burtgang, and use my oxblood key for a champion's Galea.
Burtgang TP 1st swing was 7.? didn't really care to check exact, just wanted to see the integer. TP after Atonement is 8, so it definitely is 2hits. Weird thing was I literally couldn't do a 1 hit Atonement, even when using when the mob had like 1% health left. That said, Atonement is a strange strange WS all in itself.
Atonement damage with just Burtgang: 750
Atonement with Phorcys Korazin: 802 (750*1.07) looks like Phorcys applies to both hits.
Atonement with Moogle head:765 (750 * 1.02) Galea applies to both hits as well.
I already showed that Anwig Salade only applies to 1st hit of Last Stand, so Champion's Galea should theoretically only apply to the 1st hit of a WS as well. My best guess is Atonement itself is just weird. Headpiece working and the fact that I couldn't get a 7tp return leads me to believe that Atonement probably isn't good for testing this anyway. Even on a lvl 1 mob I had an 8tp return WS. My assumption is that even though you get the tp return of 2hits, Atonement is still calculated as a 1hit WS or something else strange. Whatever it is, it sure isn't treated like any of the actual physical Weapon Skills, which makes sense seeing as how it isn't a physical WS, and as such, Phorcy's testing data using Atonement can't be applied towards anything but itself.
A quick test with Phorcys body yielded an 802 Atonement. 750*1.07=802.
Edit: Beat to it, and by much better testing.
Does offhand apply to atonement? Did you check the TP return to see if you receive 9 TP from Lv1 mobs?
Offhand usually doesn't apply to magical ws which is kinda what atonement is. Sounds like they had other plans for it and just never took out the extra tp gain
Is it even possible for the 2nd hit of Atonement to miss (or for the WS to miss at all)? It's highly possible that because of the way it's calculated, it functions very differently from normal multi-hit weapon skills.
