This is far from the end-all-be-all and I expect many would add Army Cache Boost or additional Auto advancements in lieu of Item Sell Value or Army Camp Discount. Nonetheless, a good starting point for discussion.
The question becomes, do you do the minimum in each phase, get 100k in phase 4, and then Super Ascend, or is there value in upgrading P1-3 advancements beyond the bare minimums?
Let's exclude the idea of investing hard along the way and doing AP resets as required.
Ooof yes of course you guys are right. 100k in Level 4 only.
At minimum, spending “extra” in Level 1 is needed. +25% Joint Strike and +30% Additional Mercs is already at 1,000 AP. I think more mercs is a hard requirement and I assume most would want extra idle time and probably stats too.
Likewise “extra” in Level 2 would happen naturally but it’s close. +25% AP and +100% Alloy Sell Value comes at 9,500 against a 8,000 cap. Maybe you can skimp here and rely on a Legendary or Insane Alloy Sell Value artifact for money generation? You’ve already skipped +100% Money Cache at this point though so money is getting tight
Level 3 you can be quite precise and hit 25,082 AP against a 25,000 cap with: +2 Level Skip +80% Money From Bonuses +80% Item Sell Value +3 Market Visibility
So it’s really just Level 1 that is the problem. I think the obvious answer is just to spend the coins here honestly.
My strat will involve playing normally until I have enough AP, then resetting AP with 150 coins to push all into Phase 4 for the next SAsc. (I obviously have enough AP to do it now without resetting. This would be for a future SAsc2.)
