Sorry disregard thread. My friend was telling me how cool the boots were so after making this post after being told he saw testing saying it gave 20% spell mp cost as TP, I got excited. Just went out and tested it, and the 20% is a multiplier to the mp, not 20% of the spells mp, as I was told.
I hate you. This is probably still relevant, the numbers are just bogus.
If you could get 20tp/cast consistently with something worth casting, Occult Acumen wouldn't suck.
So long as it never shaves a swing (see: Why Conserve TP sucks) nor gets you 100tp while using less than the entirety of your mana pool to do so, I'm still dubious as to its intentional application. I'm usually the freak who finds such applications too and I'm saying it's crap.
It's about as useful and effective as Conserve TP.
As it is, it gives 10% of MP cost back as TP. As you note the AFv3 feet double this. Store TP does affect it.
113 * 0.1 = 11.3 * 2 * ~1.30 = ~30tp
So you dump your whole MP pool just to break 100tp.
Even with the perfect combination of spells with AFv3 feet and a 40 Store TP setup for casting, you're looking at 357mp blown to reach 100tp, or 71mp to drop a 5-hit round.
I'm all for unconventional approaches, like multihit elemental WS spam as you know, but this one plainly doesn't work. The belt would have to be superior to our AFv3 and just plain bonkers broken for it to make this a viable TP gain strategy even in that "sh*t, can't melee this, stand back and build TP with spells" situation.
However if you still want to pursue this, find me the best Store TP setup you can manage while keeping AFv3 on. Actually landing the spell doesn't mean dick, we want raw Occult Acumen output. I can even give you targets for 20tp/cast:
Fire II, 68mp, 4 sec: 48 Store TP Bliz II, 77mp, 4.5sec: 30 Store TP Thun II, 86mp, 5 sec: 17 Store TP
We can also analyze efficiency in terms of time spent casting just with MP cost divided by time, culling by spells that can reach 20tp/cast realistically, but also with Store TP incorporated to reach the 20tp target:
Fire II: 17 (5) Bliz II: 17.1 (4.4) Thun II: 17.2 (4) Stone III: 17.5 (3.8) Fire III: 18.8 (3.3)
We can see that it does go up with tiers and MP cost, so higher tiers are more viable from a TP Over Time perspective, but this inverts when wanting a flat amount of TP due to only a certain amount of 'useful' TP per cast. This hit-build approach isn't just to negate a melee swing either, it's to reach 100tp efficiently.
So Blizzard II appears to be the most immediately useful spell for Occult Acumen application. /SAM, Rajas, Rose, Brutal, Hoard and Attila's or W.Tath to round it out to 20tp/cast with just 4.5 seconds casting time.
If you wanted to build to 100tp instead of just shaving hits from your build, a 25tp/cast setup might be better.
25tp Stone III: 36 STP Water III: 28 STP Aero III: 18 STP Fire III: 11 STP
So Water III is probably the best choice to dial in for 25tp/cast to reach 100.
A final option is to reach an 80tp 'minus one hit' setup in the fewest casts necessary, but we can also aim for shortest time possible by utilizing multiple spells instead of just 26.7tp three times.
With 30 STP, Fire III: 29.3 Aero III: 27.5 Stone III: 23.9 Total: 80.7tp
So with +2 boots and a 30STP casting set, Fire 3 -> Aero 3 -> Stone 3 sets a 5-hit up for an Engage-Hit-WS.
This is the best application I can manage
Yeah seriously f*ck all of that. With +2 boots you actually need +48 Store TP to reach 20tp/cast with Fire III.

I've seen things you people wouldn't believe. Airships on fire off the shoulder of Bahamut. I watched Scapula Beams glitter in the dark near the Three Mage Gate...
I was more excited for its application against future NMs that do things like Ultima's screens, Omega's four legged mode, Lusca's (and a lot of other NMs) ability to change modes and absorb physical damage for decent chunks of time.
Too bad the boots aren't as good as I was lead to believe. They could have been really good down the line.
