Unlock Potential Summary

This tier list is based on our recommendations for using Unlock Potential on 4★ Heroes. 4★+10 Heroes have the same stats as 5★+5 Heroes, so it is sometimes better to continue to Merge Allies with a 4★ Hero instead of using Unlock Potential to increase their rarity. For this reason, you should prioritize Heroes who gain powerful Exclusive Skills at 5★ or Heroes that you simply love when using Unlock Potential.

      Yes. You can buy the FEH pass again later, even if you cancel the subscription. If you cancel it, you will lose the features like Auto-Start and Re-Do Previous Turn, but you will keep Resplendent units/outfits.
