The Upgrade Vault is a key part of early progression in Idleon, giving out some of the biggest boosts to damage and accuracy when you’re first starting out in World 1.
There are also tons of bonuses for later worlds and generally useful upgrades that you will be buying out for the rest of the game, and even some upgrades that are so expensive that they’re currently impossible to max out.
The best part about the Vault is that everything can be bought with coins, so no Gems needed, and all the upgrades are shared by your entire account so don’t need to buy the same upgrades multiple times.
Upgrade Vault Priorities
Before diving into the detailed upgrade descriptions, we should cover the most asked question about the Upgrade Vault, which is what you should upgrade first and how to prioritize your upgrades properly.
Thankfully, the answer is that you simply must upgrade everything evenly, as it’s the only way to unlock new upgrades as soon as possible.
Since the costs usually scale up fast, it is not viable to max out every upgrade in order.
However, there is one small exception which is a good idea to put more coins into as soon as possible, which is Major Discount that reduces the price of all other upgrades.
| Upgrade | Description | Levels | Total Cost (rounded up) |
|---|---|---|---|
 Major Discount (#14) | All Vault Upgrades are cheaper | Level 1: -1% Upgrade Cost Level 80: -80% Upgrade Cost |  33 |
This upgrade will make every other upgrade multiple times cheaper, so you will end up saving tons of coins in the long run, but again don’t try to max this out instantly as you will gain progress faster by spreading out your upgrades early on.
All Upgrade Vault Upgrades Explained
The levels showcase the amount of bonuses you get from a single level as well as the max level of the upgrade, but it does not take into account the Vault Mastery upgrades, so the max bonuses will get even higher after you upgrade those!
The Total Cost in the table below is shown with the assumption that you have maxed out the Major Discount upgrade!
