Here is a Free to Play solution for this weeks Resonant Battles Week 180.
This week you will need two Harmonic Heroes with 0-1 merges (450 - 451 score) to stay in Interval 21. I was unable to try out 0 merges so I am not sure wether you will be able to stay. Feel free to post wether you go down or stay with 0 merges in the comments, if you were able to test it.
If you have any questions or problems with the solution, leave me a comment and I will answer to the best of my ability. #Balthiar #FireEmblemHeroes #ResonantBattles
