Upon some thinking, if a Monk can wear a few pieces of cobra unit gear for asuran (with footwork), it'll allow a 7-hit build with only +2 store TP needed during the TP phase, even if the Monk only lands 6/8 hits on the asuran. Conveniently, cobra unit gear also have +acc on it so it can be useful for asuran fists.
For asuran, wear:
cobra unit mittens, store TP +3 (acc +4) as opposed to o.kotes
cobra unit subligar, store TP +3 (acc +5) as opposed to shura haidate
cobra unit leggings, store TP +4 (acc +4) as opposed to denali
rajas ring, store TP +5
Total: store TP + 15
Asuran 6/8 hits TP return = (13*1.15)*2 + 4 = 33.9% TP
(100-33.9)/5 = 13.22% TP per hit needed during TP phase
13.22/13 = 1.017 = only store TP +2 needed.
However, using those 3 pieces of cobra unit gear means a mean loss of around +24 atk and +8 str (but net gain of +1 acc), but footwork's +10% atk bonus makes up for it. Of course, if you have usukane feet, that's a superior choice over cobra unit leggings.
EDIT: Hell, in hindsight, even if you only wear rajas on asuran, and land 6/8 hits, you still only need store TP +6 during the TP phase, which is rajas + brutal. In any case, it's easy to achieve a 7-hit build wearing almost anything if you use asuran fists.
------------------------------------------------
As for DK or any other 2-hitter while under footwork...
We can subtitute in other gear with store TP that we couldn't otherwise do with asuran, since DK doesn't require extensive acc stacking to make sure all hits land.
Gear:
cobra unit mittens, store TP +3 (acc +4) as opposed to alky
cobra unit subligar, store TP +3 (acc +5) as opposed to shura haidate
rajas ring, store TP +5
chiv chain, store TP +1
brutal earring, store TP +1
Total = store TP +13
100-(13*1.13*2)= 70.62/5 = 14.12/13 = 1.086 or store TP +9 needed during TP phase.
Even if you wear cobra unit cap (store TP +2) and ecphoria ring (store TP +1) for DK, for a total of store TP +16 on DK, you still need store TP +8 during TP phase to reliably get 100% TP in 5 hits. That means TPing in ecphoria+rajas, chiv chain, and brutal earring. While ecphoria+rajas isn't a bad compromise (ppl go rajas+ulthlam these days, which is almost the same minus 4 atk), telling the uber Monks to use a chiv chain instead of PCC or faith torque will be difficult. And I'm not about to say it's a good idea to take off the byakko haidates or o.kotes for cobra unit gear during TPing.
What does this mean?
It means that if you want a 7-hit with footwork and using DK without gimping your TP phase, usukane body is invaluable.
Unless somehow cobra unit harness (whenever it comes out) has a significant amount of store TP on it, accuracy, and STR/VIT +5-10, thus making it ideal for DK.
