Here is a Free to Play solution for this weeks Resonant Battles Week 167.
This week you will need two Harmonic Heroes with 2 merges ( 452 score) to stay in Interval 21.
If both of your Harmonics are faster/stronger than finn you can instead use Life and Death 3 as his seal and then use a Harmonic Skill that gives Resonant Blades to finn. This will allow you to proceed as normal. You can also give Ayra or Leif a Brave weapon to lower their speed if that isn't enough.
Also important to note the green thief at the end might go to the left side if you hit Finn with the Dancers veil instead of Eldigan. This ist still fine. Just wait until the final turn before he escapes and then use the Infantry boots and chase him down with Finn+ Eldigan dance.
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
