Hint Request(SPOILERS!) Mid/Late Game (I think)

[Harwin]

This is not in the open-hint thread because I don't want to even LOOK at that thread in case it spoils something for me.

I hate to ask for a hint on this game, but I've been stuck on the same puzzle(s) for 10 days now and I'm not making any progress. I'm probably overlooking something obvious (like my overly complex initial attempt at lighting the blackwood splint), but that's how it goes some times.

Since I'd like to solve as much of this as possible on my own, I'm really just looking for a suggestion on ONE puzzle I can try and solve next (i.e., that isn't contingent upon solving any of the others first). Hopefully that will allow me to focus my efforts and lead to a solution.

Here's where I'm at and what I've done:

1. I've made/encountered all 5 elements (Fire/Air/Earth/Water/Wood)
   
2. I've visited the Antechamber and all 4 Dragons
   
3. I've made both glass and aluminum permeability charms
   
4. I've constructed a wide variety of stone solvents
   
5. I've attempted to tweak a lot of rituals, fruitlessly (other than those previously implied or mentioned)

Here's what's blocking me:

• A) The graffiti - I've never done any useful interaction with it. My current assumption is these are dragons mid-subsumption but all the attempts I've made to test that have failed (and I don't know the Dracon Invocation).
  
• B) The "gravity" puzzles - the bridge to the Deep Lab and the crawlway between Baros and Pneuma. I assume I must interact with either active or subsumed Baros for both of these.
  
• C) The "exoscaphe bay" puzzles - the evacuated bay and the exoscaphe hatch - I assume I need to interact with Pneuma for these.
  
• D) The "cracks" maze - I assume Aistheta is the key here - but I've played with creating a lodestone of non-centrality as well.
  
• E) Fractures - I have not done anything interesting with any fractures - I assume Syndesis is the key.
  
• F) The Chancel - I'm assuming that I need "aura imitation" here (and that invisibility won't cut it, based on the different descriptions between this and the birdhouse stricture) but I can't test that - I haven't successfully phlogisticated electrum for a second source of elemental fire (for Invisibility), and the fractures still block me from accessing any officers. I've also tried various things on the writ screen in order to access the chancel from the other side.
  
• G) Phlogisticated Electrum - Once I make electrum, I've been unable to make catalytic environment - I assume the Deep Lab's (quicksilver?) bound will provide the solution.
  
• H) Tertiary Alchemy Lab - I have been unable to open this door. I suspect an as-yet-unknown ritual to modify the thick key
  
• I) Dragon Subsumption - Even if I don't need to make a new fulcrum(yet), I lack the Dracon Invocation necessary to complete this.

I've spent a fair amount of time on (A) Graffiti , (G) Phlogisticated electrum, (H) Tertiary lab, and (I) Attempting subsumption without the Dracon Invocation

I would really appreciate a suggestion as to a puzzle that I can solve WITHOUT first solving the others - could be finer grained than the list I've provided(if for instance I shouldn't have tied both excoscaphe puzzles together). I don't want a puzzle solution at this time(and hopefully I'll never need one) - just a puzzle that I should spend my time on. If there are multiple puzzles I could independently solve, please just tell me one (knowing whether there are multiples is also additional information I'm hoping I don't need.)

Thank you

I don't know if you've done this already, but have you used the lens to look at the glimmers? This was a major stumbling block for me and it provides several important alchemic recipes you won't discover otherwise.

You mean the sparks? Yes, I have - and AFAIK I've looked at all of the accessible ones. (I've gone and checked every rooms and I think there's even an in-game command which tells you which rooms you haven't checked yet), but thank you for the suggestion.

And I still haven't gotten past this point btw - I kept trying for another week or two after originally posting and then took a break for a bit to see if insight struck. I really don't want to look up spoilers for this.

As a note to anyone who sees this and wants to kindly offer help. I recently received a sufficient hint to get unstuck and proceed.
