1. Make sure you have all the blessings.

2. Review the mechanics in detail.

3. I personally find the Fire Boss to be the easiest to defeat. It's recommended to start with him first.

**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.

Finally, it's always good to check YouTube guides for a better understanding of the stats or what needs to be done. **For example, for the Fire Boss I recommend watching Envy, while for the Plant and Water Bosses, I recommend watching Grass Angel.**
