First up, the Meridians we're going to need at a
bare minimum, incorporating an estimated two Perception Arts trained and in active use at once.
Current Meridians:
Meridians Unlocked:
Head: 3
-Lake(AMx2), Mountain(AM)
Lungs: 8
-Dark(FVM), Music(FVM), Dark(AEx2), Earth(AE), Water(FSSx2), Moon(PLR)
Spine: 7
-Mountain (AM), Dark (SCS), Wood(TRFx2), Wind(AS), Thunder(AS), blank
Heart: 8
-Wind( FZx3), Water(FVM), Dark(FVMx2), Wood(TRF), Fire(AC)
Arm: 7
-Heaven(FSA), Wind(FSAx2), Water(ACx2), Dark(FSSx2)
Leg: 6
-Darkness (SCSx2), Moon(PLRx2, SCS), Thunder(AS)
40 Successes for next
Dropping AM, AE, AS, FZ, AC, FSA leaves us with the following (
right now):
Head: 0/3
Lungs: 5/8
Spine: 3/7
Heart: 4/8
Arm: 2/7
Leg: 5/6
Mastering FVM, FSS, SCS, TRF, and PLR to their Green Two Maximums, and not including any Arts we don't have yet, brings us to:
Head: 0/3
Lungs: 5/8 +1 (FSS) +1 (PLR): 7/8
Spine: 3/7 +1 (SCS): 4/7
Heart: 4/8 +1 (TRF): 5/8
Arm: 2/7
Leg: 5/6 +1 (PLR): 6/6
Which means... wow, we
don't need to do anything
right this instant. Okay; that's almost a relief.
We can pick up, train, and use any of the three new Perception Arts right away. CWY is Head/Spine, CDE is Head/Lung, and HDW is Head/Heart.
We
would need to open another Lung Meridian to master FSS and PLR if we master CDE to the peak of Green One prior to mastering and condensing FSS.
The same is true for either AFL or ENM. Both Arts are Leg/Arm, and we simply don't have the available Leg Meridians at this time.
Meridians (post condensing):
Head: 0/3
Lungs: 4/8 (FSS: 1. FVM: 1. PLR: 2)
Spine: 2/7 (SCS: 1. TRF: 1)
Heart: 2/8 (FVM: 1. TRF: 1)
Arm: 1/7 (FSS: 1)
Leg: 4/6 (SCS: 1. PLR 3)
We
still couldn't master AFL or ENM without opening another Leg Meridian, though ENM doesn't reach Mastery until Green Three, meaning it's not crucial to do right away. However, we
could master CDE and any other Perception Art and only need to open a single head meridian... provided we master and condense CDE
first. Given the extremely high odds that a successor to CDE exists in the Second Floor Archive, however, we'll probably want to open the other two Head Meridians anyway.
So that's three Head Meridians and one Leg Meridian. That's four AP, and requires 40/41/42/43 successes; condensing CDE and/or AFL adds another 3 AP to that each, for up to ten, not counting training them in the first place.
Now, speculation. Successors to SCS, FVM, TRF, and FSS are most likely going to require Meridians in the same areas, and are - to my understanding - going to 'subsume/include' the Meridians from the precursor Art, thus Condensing making it much easier to pick them up.
In the 'best-case scenario' that I can think of, each of those successor Arts will require one new Meridian per region - call it another eight Meridians in total - in Green Two.
In the
worst-case scenario, each will require up to four new Meridians each, for another sixteen in total in Green Two. I hope this isn't the case; I expect either two or three Meridians to be needed.
The minimum brings the Meridian Count to (again, not incorporating Arts we don't already know):
Head: 0/3
Lungs: 6/8 (FSS+: 2. FVM+: 2. PLR: 2)
Spine: 4/7 (SCS+: 2. TRF+: 2)
Heart: 4/8 (FVM+: 2. TRF+: 2)
Arm: 2/7 (FSS+: 2)
Leg: 5/6 (SCS+: 2. PLR 3)
Maximum:
Head: 0/3
Lungs: 8/8 (FSS+: 3. FVM: 3+. PLR: 2)
Spine: 6/7 (SCS+: 3. TRF+: 3)
Heart: 6/8 (FVM+: 3. TRF+: 3)
Arm: 3/7 (FSS+: 3)
Leg: 6/6 (SCS+: 3. PLR 3)
Okay then; even in that 'worst-case' scenario we 'only' need to open another two Leg Meridians (for one of ENM/AFL) and two Lung Meridians (for CDE). If we go with CWY, that's an additional Spine Meridian needed, bringing the total to nine: +3 Head, +3 Leg, +2 Lung, +1 Spine; 40/41/42/43/44/45/46/47/48 successes.
The better case is one additional Lung Meridian and another Leg meridian, for +5 Meridians: +3 Head, +2 Leg; 40/41/42/43/44 successes.
So, roughly speaking, on top of the four AP in green two to master a given Art to Green Two 'standards', it will take the following AP for each Art, not counting any additional Arts beyond mastering CDE + Condensing and one of CWY, or HDW.
CWY: 4 (mastery) + 1 (Worst Case Spine Meridian) + 1 (Head Meridian): 5-6 AP.
ENM: 4 (mastery) + 2 (Leg Meridians) + 1 (Worst Case Leg Meridian): 6-7 AP.
CDE: 4 (mastery) + 2 (Worst Case Lung Meridians) + 3 (Condensing): 7-9 AP.
HDW: 4 (mastery) + 1 (Head Meridian): 5 AP. Note: HDW doesn't need its third Head Meridian until Green Three.
AFL: 4 (mastery) + 2 (Leg Meridians) + 1 (Worst Case Leg Meridian) + 3 (Condensing): 6-9-10 AP.
The idea is to master and condense CDE
first, then learn the other Perception Art. Otherwise, we'd need two additional Head Meridians for CWY or one for HDW... but we'd also skip on condensing CDE, which we might want to do to pick up the successor. Which probably requires more Head and Lung Meridians
anyway.
Bit of a wash, that.
Condensing AFL is put in mostly because it
could be done.
Still, even in the 'best case' and minimizing times (no condensing; CDE, HDW, ENM), that's 4 + 6 + 6 = 16 AP.
I'll get to the actual math later - what we'd need to do to drop AP expenditures for mastering Arts, for example.
