While it may be more difficult to earn free Crypton as a free-to-play player, it's definitely still possible.
This section will outline every step that you should aim to take to maximize your potential free Crypton through the passive Crypton system.
Step #1: Equip the passive Crypton pet abilities on as many of your active pets as possible.
Since you can't generate passive Crypton through the duplicate ability-set system, you need to start with pet passive abilities.
So, make sure you do the following:
- Capture each faction's hatchery in Geopet GO.
- Get your best pets from each faction to as high a level as possible (level 3 minimum).
- Equip an ability-set with at least one passive Crypton ability (preferably both) on your best pet from each faction.
By doing this, you should be earning your first bits of passive Crypton. Eventually, you'll end up receiving some free Crypton which you can eventually use to purchase some ability-sets.
Step #2: Gather up as much free Crypton as you can.
For this step, you need to ensure you are getting as much free Crypton as possible. Without Crypton, you simply can't purchase duplicate ability-sets and increase your passive Crypton generation further!
At this point, you should be receiving free Crypton from the following sources:
Both of these sources will give you the best possible chance of earning free Crypton as a free-to-play player. So, you need to sure you are taking advantage of them and gathering up as much free Crypton as you possibly can!
Step #3: Equip the Pet Trainer ability on any free slots in your active pet ability-sets, and then purchase your pet ability-set with the most duplicates.
Essentially the point of this step is to purchase your pet ability-set with the most duplicates at the most discounted price possible.
In order to do this, you need to make sure you are equipping the Pet Trainer ability on your active pets. In each of their ability-sets, you need to look for any slots that don't have any passive Crypton abilities. In any of those positions, equip the Pet Trainer ability.
Once you've done so and waited until the weekly reset (Friday, 12AM GMT), you can go ahead with purchasing your pet ability-set with the most duplicates.
Simply head into the Spellbook, switch to the pets section, click the Crypton book icon, click "Invest", and then purchase as many discounted ability-sets as possible.
As a result of doing this, you'll slowly start to gather more duplicate pet ability-sets, and as a result, you'll improve your passive Crypton generation even more.
This is likely the best possible way that you can approach passive Crypton generation as a free-to-play player.
If you follow all of these steps as a free-to-play player, you'll likely get yourself a good amount of Crypton all for free!
This strategy also works out well if you're a very low spender. However, if you're a big spender in Clash of Streamers, the next strategy will probably be best for you.
