Looking For MNK Sublte Blow Set.

I think the WS gear is more problematic than TP.
For WS you want to use 3 items from Moonbow+1, Sherida, Mpaca legs and Niqmaddu for SBII and to cap SBI you want either Auspice or two pieces of kendatsuba+1 (most likely from feet,hands,head) or Schere and Kendatsuba body if Impetus is down.

3 items from Moonbow+1, Sherida, Mpaca legs and Niqmaddu for SBII

According to BG, the cap is 50 for both SBI and SBII for a combined total of 75, so you could use all 4 alleviating the SBI requirement by 5.

No on the latter. MNK has 35 base Subtle Blow, so you just need to fit 15 into your sets, and there's multiple ways to do it.

Schere Earring - 3
Dignitary's Earring - 5
Chirich Ring +1 - 10
Bhikku Crown +3 - 14
Kendatsuba +1 set - 8/10/12
Hesychasts's Crown +4 - 12
Hesychast's Gloves +4 - 10
WHM main or sub Auspice - Varies
Food - Varies

So for instance, a single Chirich Ring +1 and a Dignitary's earring caps your subtle blow 1 trait across all sets, and only uses 2 slots (the accessories, the weakest ones, though you might not want to lose Moonshade Earring). You could also just throw Mpaca's Hose + any 10 Subtle Blow+10 piece on and call it a day.

You will almost always be using Sherida Earring, Niqmaddu Ring, and Moonlight Belt +1 in all of your TP/WS sets, so there's your 25 SBII. If you're doing a WS at attack cap, you're probably using Mpaca's Hose for 5 more, so you can drop 5 from your SB1 set and still hit cap.
