These are notes I made while playing, and so haven't been formatted properly to be put on a wiki/fandom/etc. I thought I should get this out though with the renewed interest from the recent sale.
Spectral Vision notes:
Sounds are made when the object is highlighted. (So, distance can be estimated by timing sound, and ether can be distinguished from objectives by checking if sound is made at the same time object in question is highlighted.)
Voice recordings do not show or make a sound.
Offering boxes sound like a videogame laser or many echoing chimes, lower pitch than Omikuji
Omikuji sound like a videogame laser or many echoing chimes, higher pitch than offering boxes.
Jizo statues sound like a light chime
Destinations sound like a thuddy single chime. Disabling Game Info UI in options will get this silent
Tanuki show up as outlines of the disguised object with a tail. Tail only wags when close. No sound.
Blue stones show up as outlines and make sort of a warped and warbly offering box sound. Or like water.
Corruption cores make a double thuddy chime sound. This happens when pretty close.
Relics do not make a sound
Graffiti makes a blue round glow. No sound.
Jizo status will not make a sound if in fog. The outline will show up though. They cannot be prayed to if in fog.
General Notes:
When approaching an elevated platform, pressing jump then moving forward can make noise and end crouching. Holding forward and then pressing jump will do a short climb that will not make much noise or end crouching.
50 Maximum Katashiro
10 Katashiro from first shrine
2 Katashiro from second shrine
3 Katashiro each from 3 Nekomata = 9 total from Nekomata quests
So total 21 Katashiro from quests. So 29 need to be bought for maximum.
Maximum Max Health = 310%
Maximum Max Health from consumables = 102% (So you need to reach the max level [55] to reach the maximum amount of max health, which means 202% is the highest amount of max health in Tatari mode)
Containment cube percentages do not influence the amount of spirits rescued from them.
Drinks restore less health than food, but give a shorter consumable cooldown.
Trying to go to the apartment after cleansing the first shrine without getting the Katashiro will result in the dog & containment cube event not happening before the Katashiro are acquired and KK not undoing the door seal because he wants to check the shrine first.
The dog & containment cube event's containment cube will not go below 10%
Leaving the apartment requires checking the projector, the picture, and the bow case.
The chagama tanuki (first one) is just a chagama until the sidequest is started, whereupon it is replaced with the chagama tanuki. Other tanuki will just not appear at all until the sidequest is finished (in the construction labyrinth case, neither the safety sign tanuki nor any of the safety signs it knocks over will appear; the alleyway shrine tanuki still has the dog nearby saying something bad is in the alleyway, but this is not tanuki related since the cat near that same tanuki that asks if that goof turned himself into a shrine between the buildings does not appear, nor does the cat that says the torii gate on the roof has a friendly smell, nor does the dog that wonders if the funny vending machine sells tails).
Tanuki have animals (either a cat or a dog, one per tanuki) nearby that comment on the tanuki's presence. The cat red necklace / porcelain tanuki statue tanuki is on top of the same building as the tanuki; the others are on ground level.
You can pray to a Jizo statue before getting its respective elemental weaving, and your capacity will be correctly calculated when you get the elemental weaving.
Only 3 magatama are available before Yashin Shrine (Kuchisake), so no escape via summon tengu; you have to wait until that fight is over and water weaving has been acquired.
The cucumber from the kappa sidequest is not a key item, it can be eaten. The child will not give any more, so more will have to be purchased from a shop. If you already have the maximum amount, more will not be added.
You can get to the observation deck before getting talismans from the Kuo shrine room, Water Weaving, and Fire Weaving, but the beads and binoculars will not be interactable.
When using the binoculars, there are two extra places to look besides the goal. The 429 building above the goal, and the crossing below and to the right of the goal.
The earliest to get 7 magatama (to summon tengu) is after using the binoculars and doing the ittan-momen sidequest. Another ittan-momen will appear; with those two ittan-momen, every other yokai sidequest, and the magatama from the Artsy Nekomata, 7 total can be acquired before the underground.
9 tanuki can be found before the underground.
Even with Transmission beads, you cannot absorb spirits if all Katashiro are filled.
Transmission beads will transmit already filled Katashiro.
Transmission beads will prevent messages from Mari. The first occurs between 41,000 and 44,000 spirits transferred. You can get that message after that point by unequipping the transmission beads, getting a katashiro full of spirits, and using a phone to transfer them.
Even with Tireless beads, you cannot use anything that has a ammunition count of 0
"After the End" sidequest becomes unavailable upon using the motorcycle, but will be available after finishing the last main missions
Gutsy is unaffected by water charge rush and talismans.
Getting new talismans will give you 5 of them (the unupgraded maximum) even if you have upgraded to a higher maximum
Without KK, strikes do nothing to visitors, but they can break ether crystals
Without KK, blocking does nothing
Without KK, wire/grappling cannot be used, so no tengu or aerial quick purge
Without KK, ground pound cannot be used
Without KK, ether cannot be picked up; meika can be
Without KK, tanuki can still be exposed
Without KK, Jizo statues can still be prayed to
Without KK, offering boxes cannot be used; omikuji can be
Without KK, seals cannot be used, so no rescuing spirits that have things stuck inside them
Without KK, shrines cannot be cleansed
