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.
