Notations:
SLX(A, B, C) means you can go up to SLX, where A SLs(Singularity Level) are from DM(Dark Manifolds), B SLs from Manifolds, C SLs from Nw
SF is shortterm for Singularity Function
SF11 means the 1st function on the 1st row, which is the free upgrade
SF23 means the DM cost scale decrease upgrade, etc.
[11, 23] means getting SF11 and SF23, and will be used to notate(Is that even a word lol) a function preset
IM stands for incrementy multiplier

Intro:
You should be at SL20(7, 10, 2) when you just enter this era
The costs for next SL, before any functions, should be 7.813e10 DM and 1e24 Nw
Get the free function, so you gain refund point on collapse, now farm yourself some refund points.
BEFORE YOU FOLLOW, export so you can try again if you screw up and find yourself stuck, follow the checklist carefully.

Make sure you bought SF11 again, or you gain no refund points
Get down to SL1
Turn all booster upgrade autobuyers on
Turn collapse and FB confirmation off
Turn autocomplete challenge on, set amount to 3 and 11
PS: If you wanna know why aren't we doing C8.12, you reach C8.11 with the 1%/s gain without needing to manually markup, which speeds thing up
Turn "Factor Boost if possible on entering a Challenge" on
Set auto collapse timer to 0 and turn it on.

Now you need to do some speedruns, here's the quicker way
Wait 3 secs, Do C8, Wait 3 secs, Do C3, wait till collapse, rinse and repeat.
Farm for a while, around 25 is enough, but 50 will be safer.

After that, you can enter the world of singularity functions, read the goals and if needed the guides below

Goals:
The following SLXs will work as a target for you to aim for, read the guide at the end if you don't know how to reach one of them.
In case that you got more Nw SL somehow, you can still follow the goal, but you should be able to afford better presets, skipping about one step ahead in the guide presets
+X means getting X level on it, ~ means no increase

Guide (SPOILERS):

Generic tips

Whenever you are farming decrementy, make sure you downgrade your SL, all the way down to level 1, it's very significant boost, i mean very.

When you are done farming decrementy, make sure to have SF31 in your preset before buying DM, it's a worthy amount of extra DMs.

Try to find the most optimized SL when farming incrementy, just like optmizing the FB/s gain, higher isn't always faster.
I like to metaphor that like you are shifting gears, if you shift up too early you are slowing yourself down, but if you never shift up you are limiting your max speed, pretty fun imo.

In case you wonder what that "Base 6 is now base 5" does, it 3x the FB/s
As of why, quoting Lookas123's explain, "it gives you more fb/s since then you get 666666x passive op gain in base 6"
And because you start in base 6 due to "The base is reduced by 4 if it's over 7", it basically makes the slowest part disappear, thus the increase.
That's why you should keep auto upgrade on, too.

Howto for the goals

SL20->21
Simply get SF23, and then you can get another SL free of cost, easy.

SL21->23
Get down to SL1 again
Enter C8 with the preset [11, 22, 31], when you get enough DMs, switch to [11, 13] and get those 2 SLs

SL23->25
Stay in C8, now get SF42, and with the boost grind more DM, get the ee12 upgrade when you can, you know the rest.

SL25->27
Now switch to [11, 22, 32], and just like when you get third row in incrementy, the decrementy goes crazy, enjoy it and benefit from it while the inflation haven't stopped yet.

SL27->33
Get SF42 again, and let it go idle for another while.

SL33->38
Now get SF31, which is another healthy 6x to your DM gain, with that get the last wave of SLs in this long C8 run

SL38->40
Keep the preset from C8, get your SL back to max level again, you might need to farm some FB again, otherwise this is straightforward.

SL40->42
We are doing this because we also need more N2 power to do C8.13, using the preset [11, 22, 31, 42, 52], do the standard trick to farm cardinals.
Here are the details if you don't know how
1. Get as many FB as you can in a run
2. Collapse and quickly finish all challenges, then farm more FB until the run reaches 1000s
3. Collapse to increase the most cardinal collapsed at once
4. Wait till the passive gain gives you enough cardinals
After that, distbute all, watch the N2 mult go up for a few seconds, and finally buy half of max Nw, and get those sweet SLs using SF21.

Finish C8.13
The magical preset you need is [11, 22, 32, 42, 52], with that and enough N2 power, you will finally be able to squash another completion out of C8!
If that wasn't your story, make sure you finished C7

Finish Baseless Milestone 1
Now you can get SF51, which unlocks baseless milestones!
Before you can reach high in C4, you must regain ticket to C4
The "You can enter challenges past 3 completeions" upgrade is your ticket, farm boosters until you can afford it.
Now enter C4 again, and not just for few miliseconds this time, spam M for a bit and you should reach the milestone in no time.
I hope you ran out of refund points before, because now you will never get another chance on that!

SL42->SL43
With the boost from C8.13 and the new SL, another usual run leads to a brand new manifold!
But if you want to go faster, try Lyhe#9049's build: [11, 22, 31, 42, 51, 62]

SL43->SL49
The preset to another inflation is [11, 22, 32, 42, 51, 62], remember the first time you got SF32? Yeah.

SL49->SL54
Get SF31 again, and enjoy another wave of inflation.

SL54->SL55
First farm FB with [11, 22, 31, 42, 51, 62, 72] till you have about e16 boosters, then switch to [11, 22, 31, 42, 51, 52, 62] for 1.5x T2
You know the rest.

Finish C8.15
This time the magical preset is [11, 22, 31, 42, 51, 61, 62], make sure to turn off auto factor shift and auto challenge completeion, now manually shift to base 5.
Press M a few times and be surprised at how high your OP is now, imagine if you can get SF32 while doing this...

SL55->SL56
It is really the same as SL54->SL55, yeah, C8 is OP.

SL56->SL58
The recipe for FB is [11, 22, 31, 42, 51, 62, 72], and now do the old stuff, check the SL40->42 part if this isn't clear.
You might want to try baseless milestone 2 before you collapse after the FB grind.

SL58->SL59
Good news, we are one SL away from another infaltion, bad news, there is one last time wall to get over.
Use [11, 22, 31, 32, 42, 51, 62], the extra N2 from the last Nw buildup should make it very slightly faster.

SL59->SL60
The key to inflation this time is [11, 22, 32, 42, 51, 61, 62, 71], that's a healthy 100x to your previous best!
Make sure to get new SL as soon as you can this time, because with SF71 more functions means more OP, which means more decrementy.

SL60->SL64
With SL60, you can switch to [11,22,31,32,42,51,52,62] to have even more decrementy per second, just make sure to use the build up there to reach w4 after you reenter the challeenge.

SL64->SL65
Well, just get another manifold.

Finish C3.16
Based on 1e308#7505's guide
0. Get back to SL1
1. Get to w4 with [11, 22, 31, 42, 51, 61, 62] and base 5
2. Get as many OP as you can with [11, 22, 32, 42, 51, 52, 61, 71]
3. Reduce C8 goal with [11, 22, 31, 42, 51, 63]
4. ???
5. Profit.

Finish baseless milestone 2
Do a overnight FB grind run, then enter C4 with [11, 22, 31, 42, 51, 52, 62], make sure to get down to SL1, and it should be done.

SL65->SL69
AFTER the Base 6 is now base 5 upgrade, grind for another day, and then do the classical stuff, make sure to export first in case you screw up C8.16.
Now, while waiting for the cardinals to go up, why not farm some DMs too?
The ultimate preset will be [11, 22, 31, 32, 42, 51, 61, 62, 71], now just put it there and sleep while dream being in the exclusive club!
...Just to realize one overnight might not be enough or Patcail just published another update.
