How to Beat Lord of Eroded Primal Fire Boss

Use Characters' Nightsoul Blessing

All Nightsoul Blessing Characters
Mavuika	Citlali	Xilonen	Chasca
Ororon	Mualani	Kinich	Kachina

The Lord of Eroded Primal Fire is stationary most of the time. Still, it will periodically summon three pillars, three Tenebrous Mimiflora, or shield itself with Void Ward, which is a shield used by Tenebrous Mimiflora and Tenebrous Papilla.

When the boss summons either of those three things, remember to use characters who use Nightsoul's Blessing to give you a strategic advantage against the dragon.

Nightsoul's Blessing and Characters

Destroy the Three Pillars With Nightsoul Blessing

You need to destroy the three pillars, that will be summoned on the battlefield, with Nightsoul Blessing attacks. Destroying all three pillars will stun the Lord of Eroded Primal Fire for a short time, giving you the chance to go all out against it.

Be Mindful of the Battlefield

Although the Lord of Eroded Primal Fire doesn't move around that much compared to other bosses, it can use its sword to slice off a portion of the battlefield from time to time. It can do this for a total of three times.

This gives you not much ground to dodge and move around, so you always need to be mindful of how much of the battlefield is left.
