Some small notes at the start:

“Permaslot” stands for the set of heavenly upgrades called Permanent upgrade slot I, II, III, IV and V respectively. These allow you to take any upgrade from an ascension you just completed, put into the permaslot and keep that upgrade at the start of the next ascension (with the exception of a few upgrades like the research center ones, which can’t be slotted).

At the start, after the first ascension, you only have 1 permaslot available (100 heavenly chips), but as you keep going and start the midgame, you’ll have more prestige to actually buy the remaining 4 permaslot upgrades (the second for 2,000, the third for 30,000, the fourth for 400,000 and the fifth for 5 million heavenly chips respectively).

Your ideal upgrades to permaslot will change throughout the game, as such it’s important to make a habit of updating them every ascension. It will save you a lot of work, since it essentially allows you to get a ton of very difficult to get upgrades very early on.

I will always list the upgrades in order from MOST important to LEAST important to permaslot and add any relevant notes after each upgrade name, since some of these are situationally dependent on you having done certain things in different orders. Generally, if you’re missing the first upgrade listed, you should slot the second one, and if you’re missing that one too, the third one, etc.

IMPORTANT FOR NEW PLAYERS: Before you press the “Reincarnate” button, you HAVE to assign the upgrade first! If you already started a new run, you cannot go back and slot in an upgrade from an earlier ascension! You also cannot slot any upgrades in the middle of a run! During the ascension screen after a run ends, you need to click on the Permaslot you just bought a second time, only then will the game allow you to actually assign an upgrade, as seen in the below image!

With all that out of the way:

(WARNING: The following list is very long as there is no easy way to summarize the order of these upgrades other than listing ALL OF THEM from most important to least important. If you don’t have some upgrade, skip over it. I will list all the prices for each upgrade, to make planning ahead easier. These are NOT listed in order of strictly cost, but rather a calculated combination of cost vs. benefit.)
