In this guide you will find rules of thumb, since nobody figured out the math yet.
This guide contains some basic rules which will help you to progress faster. Not all of them are optimal or even gonna stay true in future game updates, but hopefully they will help you get a "feel" of the game.
When to Reset?
That is probably the most important question in the whole game. And here is what I recommend.
Rule of thumb: Each minute spent not progressing means lost gems, so reset as soon as you stop progressing.
Each 500 gems mean an additional gold chest, opening which can give you very substantial boost, so trying to maximize their amount is very important. Much more important that trying to get 100 gems for completing a quest, for example. Because in time you spent accumulating upgrades for the boss, you could get much more than 100 gems through levelling again.
When to Use Silver and Gold Chests? What Kind of Chest is Better?
That is a very common question, and it pretty easy to answer.
Gold chests are to be open immediately. They contain 5 items, which can be either usable or equipment.
Silver chests are better to be opened at the point when you about to reset. Silver chests contain lower tier equipment and gold, which is why you want to use it later, since amount of gold you receive seem to be dependant on the the level you are on right now.
Which chests to buy?
I personally recommend buying gold chests, but that is up to you, honestly. But having a chance to get one or two very, very powerful items seem much better than getting ten mediocre ones to me. But I warn you that I may be wrong on this one, since I did not do the math to see which is better in the long run.
Divine Favors: What are Those and What do They Mean for You Progression?
Divine favors (df, divines, favors) - whatever you call them, each divine favor increases your gold find by 1% permanently, through resets. It may not seem huge, but it is becomes very noticeable when you get thousands of them.
Amount of divine favors you get depends on amount of gold you earned in a run.
What having divine favors mean to you?
Here's an example. You got to a certainl level and are stuck. If you follow my rule of thumb, you will immediately reset. That means you will get some divine favors, and when you progress back to the point where you are stuck, you will have more gold. And not just more gold - more divine favors too!
To reiterate, the more divine favors you have, the faster you can accrue them on next runs. So don't hesitate to reset.
What is Freeplay? What are the Benefits or Freeplay?
Freeplay is an adventure that opens after you complete one of the first missions requiring beating level 50.
Freeplay allows you to progress faster, because you can disable "cinematics" (dialogue) for it in game settings.
Because of that, unless you aim to complete a mission, you should primarily play in freeplay mode.
Idle Champions is a bit different from other idle games, since clicking is not very effective in the beginning. When your divine favor value gets high enough, you will be able to get much more gold quickly, and that's when you will be able to one-click enemies, allowing you very fast level progression.
But that's not all there is to clicking.
Clicking also staggers enemies, allowing you to defeat some bosses earlier. Don't forget about that, as it can save you some time on difficult bosses.
