What is the most efficient upgrade path?

Question

In Vampire Survivors, I've been mostly focusing on the Greed upgrade to help speed up my overall ability to upgrade by getting more coins, and then upgrading other things (extra damage/attacks/cooldown/etc). Considering that upgrading something will increase the cost of other related upgrades, as well as the ability to refund all upgrades at 100% cost, what is the most efficient way to buy every upgrade for the least amount of coins given that I have all upgrades unlocked?

Answer 1

While from a pure "spend my money most efficiently" standpoint, "priciest thing first" is correct.

But if you want to get the most money in the fewest runs, then a luck-based build is the best.

If you don't mind skipping regular progression, then using secrets to get the Yellow Sign early and from there the highest Luck characters, for the money-giving chests to have high amounts of money, from Endless Mode, extending a run and giving more Chests.

If you go that route, then you'd want Toastie unless you have over 7777 gold and are pretty good at getting to about Level 142, since only then does Smith IV get more lucky than Toastie.

But surviving to the end of a regular run would give multiple thousands of coins anyway, because of how many Chests appear.

....

The method to get Secrets and Spells the fastest:

An alternative way to unlock the secret menu is by clicking on the sixth relic icon with the pink background (the Yellow Sign) in the collection seven times. A message saying "You are now a magician!" will appear on the tooltip and the secret menu will now be unlocked. This allows the player to cast spells right away at the start of the game, instead of slaying Sketamari. It must be triggered again each time you open the game until the relic is collected.

Answer 2

The most efficient way is by always upgrading the most expensive item first.

I was googling the same question and there were suggested paths but they didn't make sense + the game is being updated every week and there are few items that might not be worth throwing so much coin at (reroll and skip)

1. Go through all the items
2. See which upgrade is the most expensive
3. Buy that
4. Go back to step 1. until you have everything upgraded

Every time you buy an upgrade all the remaining upgrades become more expensive thus going for the priciest items first is the best strategy.

That all goes out of the window if you can't afford all the upgrades (100k+) If that is the case then buy upgrades based on your style, you can later re-set for a full refund and buy differently.
