About the new Sublime collectables for Aetherial Reduction into Glioaether

[Caimie_Tsukino]

Items & Nodes Location:

Prime/Sublime Crystalbloom (BTN) (Prime & Sublime Collectables for Aetherial Reduction)
Ultima Thule (Abode of the Ea) 10:00 (27.9, 13.1)

Prime/Sublime Siderite (MIN) (Prime & Sublime Collectables for Aetherial Reduction)
Garlemald (Camp Broken Glass) 12:00 (32.1, 35.0)

Details:
3700 Perception is REQUIRED to play this collectable game. Do NOT even bother to engage the node if you do NOT have this perception amount.

Prime/Sublime Siderite (from MIN) both give EARTH crystals & clusters.
Prime/Sublime Crystalbloom (from BTN) both give WIND crytsals & clusters.

If the collectable is a "Prime" rather than "Sublime", then will likely just give you 30-ish crystals and 20-ish clusters when you carry out Aetherial Reduction.
However, the "Prime" collectable still has a very slight chance of obtaining 1 Igneous/Verdurous Glioaether from Aetherial Reduction (like 1 in every 20 of them).

If the collectable is a "Sublime", then it is guaranteed to give you 1 Igneous/Verdurous Glioaether from Aetherial Reduction.

Your chance of obtaining Sublime collectables is 0% unless you reach the maximum of 1000 collectability.

The Gathering stats is what dictates the final % chance of obtaining a Sublime after reaching 1000 collectability.
E.g.
3598 Gathering = 5% when collectability reached 1000
3601 Gathering = 5% when collectability reached 1000
3603 Gathering = 5% when collectability reached 1000
3606 Gathering = 6% when collectability reached 1000
3610 Gathering = 6% when collectability reached 1000
3624 Gathering = 6% when collectability reached 1000
3630 Gathering = 6% when collectability reached 1000
3633 Gathering = 6% when collectability reached 1000
3634 Gathering = 7% when collectability reached 1000
3635 Gathering = 7% when collectability reached 1000
3644 Gathering = 7% when collectability reached 1000
3658 Gathering = 7% when collectability reached 1000
3693 Gathering = 9% when collectability reached 1000

From this data, it can be estimated that approximately every +28 points of Gathering will grant us +1% of Sublime acquisition rate.

Below is a estimation of the relationship between Gathering vs % rate of Sublime:

*Note this is just an estimation. Real data may differ from this slightly.

Random Bonuses of the Nodes:
Note that Yield & Boon bonuses have NO EFFECT on collectables. So the only bonuses that are important are the ones that affect GATHERING ATTEMPTS.
E.g.
3750 Gathering -> Gathering Attempts +2
Max GP > 830 -> Gathering Attempts +2
(Note: Using the Gathering vs % Sublime relationship graph above, we can estimate that even at 3750 Gathering to gain the +2 attempt bonus, our rate is going to be ~11% only.)

Unlike the new Patch 6.2 nodes, >3800 Perception doesn't give any Boon chance bonus (Boon bonus doesn't help with collectables anyway).
So for these Sublime Siderite/Crystalbloom, 3700 Perception is all you need. Sure, more perception will help with collectability. But if you use the rotation of
Scrutiny (200 GP) > Collector's Focus (100 GP) > Meticulous Prosp > Scrutiny (200 GP) > Collector's Focus (100 GP) > Meticulous Prosp,
then you will likely hit the max 1000 collectability if you have 3700+ Perception anyway (Collector's Focus brings your chance of extra collectability to about 70%, and you need that extra collectability to reach max 1000 with just two Meticulous. If any failed, then you need to supplement with an extra Meticulous).

In summary, for these Sublime items, my recommendation of stats are as follow:
Gathering: As high as possible to increase chance of obtaining Sublime after reaching 1000 collectability
Perception: Just need more than 3700 (but I aimed for 3800 anyway so I get the Boon bonuses for the new 6.2 nodes. However, because I aimed for so much Perception, I do not have as much as 3750 Gathering to get the +2 Attempt bonus for these collectables... apparently you can only go for either 3800 perception or 3750 gathering with your melds... unless you sacrifice a lot of GP).
GP: ~900 to carry out the above rotation plus using Solid Reason / Ageless Words once (+ Wise to the World once if you have that Eureka Moment buff). Can be a little less than 900, assuming that you gain a little bit GP each time you collect an item.
