Kick Attack is a little strange atm I think. Some of the equipment would add base damage, some would give extra KA%. My personal preference atm is if its KA+ then it's KA% and if it's Kick Attack Attack+ then it's +DMG.
No.
KA equipment in the leg slot increase the proc rate of KA (once per attack turn, can't proc on WS)
KA equipment in the feet slot increase the base damage of the Kicks.
What's ironic is that KA used to be that low chance proc once per attack round with an incredibly high damaging kick.
Now even with the best KA equipment, kicks do way less damage than your fists hahaha, they've been so lazy they never bothered to fix this :P
The old Footwork used to give a ~10% attack increase on kicks. New Footwork keeps this attack bonus, but differently from the old one, you can't see it any longer with /checkparam or Equipment menu.
It only applies to kicks of course, kinda like the KA Job Points category, won't see it in menus/checkparam.
Old Footwork used to give a ~10% att increase.
Tantra Gaiters made it ~13%, Tantra +1 made it ~15%.
It's likely to assume Bhikku makes it 17% and Bhikku+1 20%.
Shukuyu Sune-ate possibly make it 25%?
To receive this bonus with old Footwork you only had to equip the equipment during activation of the JA, I'm not sure if this is still the case (anybody wants to test?)
I performed a test some time ago in Abyssea Konschtat against Lizard (capped attack) to check Naked feet vs Bhikku+1 vs Shukuyu vs Sokushitsu .
Can still find my test many pages ago.
I equiopped the first stage H2H relic weapon (+1 damage, +999 delay) to make attack turns slower and be able to more easily discern between normal attacks and kick attacks.
In my test I didn't see any boost to the KA rate during Footwork, but then again that test was faulty because of several mistakes I made, so I'm not sure it leads to anything.
I asked for suggestions on different test scenarios but hardly anybody provided tips or directions and I kinda suck with this sort of math stuff so:
tl;dr => it would be really awesome if someone could go back and perform this test again.
Against mobs of the same level (check with Battlemod), with capped attack and with stage1 Relic weapon in hand, it should be really easy to discern between fists and kicks from the log, and with a sample large enough you should see differences in the KA activation rate.
Against mobs without capped attack instead it should be easy to see the difference in the att % bonus granted to kick attacks during footwork. Difference betweeen 10% (base) and supposed 20/25% should be big enough that you should immediately notice it even with a small sample, provided you're far from attack capped against the target.
Ideal testing for this would be a MNK who doesn't have any Footwork JP yet, because that increases KA base damage during Footwork making it a bit meassier to set things apart.
