1. You will want all the blessings.

2. Review the mechanics in detail / read!

3. Start with Fire!

**Fire Boss:**

Use Fenne with Tywin and two heroes equipped with Tagahel. The strategy basically involves a Tywin with base speed, high HP, and Effectiveness to apply Defense Break constantly.

**Plant Boss:**

Use heroes who can apply Burns quickly. Robin, Aramintha, Carrot, and Holiday Yufine are very good options. Hazel is required to keep the team alive, but the blessing upgrades suggest she can later be replaced by Yufine.

**(Important:** You need artifacts that help your heroes cycle their skills faster.)

**Water Boss:**

Use heroes who can reliably Counterattack. Charles and Ervalen are good options. Roana, Ray, and Bernand are good healers who can keep the team alive.

Good luck to all
