Duplicate ability-sets are simply ability-sets that you have collected multiple times.
As you collect more heroes and pets, you will start to encounter heroes and pets with ability-sets that you have already collected. This is a duplicate ability-set!
Why are duplicate ability-sets important?
Well, for starters, not all duplicate ability-sets are important.
The only duplicate ability-sets that matter are the following duplicate ability-sets:
- Your streamer ability-set with the most duplicates
- Your pet ability-set with the most duplicates
If you had one streamer ability-set collected three times, and a different one collected two times, only the ability-set collected three times will matter.
The same thing goes for pets.
Your streamer and pet ability-sets with the most duplicates are important for the following reasons:
- Your streamer ability-set with the most duplicates will grant you an achievement; giving you an achievement chest, Legendary Star, and increased passive Crypton generation
- Your pet ability-set with the most duplicates will grant you an achievement; giving you an achievement chest, Legendary Star, and increased passive Crypton generation
You can find your duplicate ability-set achievements in the streamer and pet sections of the Achievements building.
This is why duplicate ability-sets are so important! The more of them you collect, the more achievements you will collect. As a result, you will earn more Crypton passively, collect a ton of easy loot, and complete the Legendary Event quicker due to the number of Legendary Stars collected.
In total, you can collect up to 2,000 duplicate ability-set achievements; 1,000 for streamer duplicates, and 1,000 for pet duplicates.
This is an absolutely insane number of achievements. If you manage to collect the full 2,000, it will have an enormous impact on your account progression.
Now that we've established the importance of duplicate ability-sets, your goal should be to get as many duplicate ability-sets as possible.
