This is a guide for the Ethel and Cammuravi’s Ferronises boss fight found in the Pentelas region in Chapter 3 of Xenoblade Chronicles 3.

How to Beat Ethel and Cammuravi’s Ferronises¶

Oh boy, this is your biggest test in Xenoblade Chronicles 3 yet and there’s no catch to this, you do have to fully defeat both Ethel and Cammuravi in this battle. Due to the sheer output of damage that you’re going to be up against here, you’ll want to make sure you’re using the 2:2:2 Class setup for the party and then take a Healer for your Hero, either Isurd or Valdi are incredibly useful for the extra healing they can provide you with for the battle.

If you’re using any Classes with a low Rank, consider switching to some of your more favored maxed out Classes for this battle, every little helps. For your Attackers, you’ll want to make sure you have at least one character as a Flash Fencer, Cross Impact is a fantastic Art that will increase the damage of your next Art which will be useful in this battle.

You should make Ethel’s Ferronis your first target and you can get a look at both her and Cammuravi’s Arts below:

Ethel’s Ferronis Arts¶

• Merciless Dance: Ethel will go wild with her blades, dealing multiple hits that can inflict moderate damage should they all connect.

• Tempest’s Edge: Ethel will take a step back and then lunge forward with many piercing thrusts dealing moderate damage if they all connect.

Cammuravi’s Ferronis Arts¶

• Conflagration Blade: Cammuravi will charge the Art and then swipe a single target for moderate damage and inflict the Blaze debuff.

• Seal of Divine Fire: Cammuravi will charge the Art and then swipe at a single target, dealing moderate damage and inflicting Launch.

• Heaven’s Fire Bloom: Cammuravi will charge the Art and then perform a two-hit combo on everyone in front of him dealing moderate damage.

As you can see, Cammuravi’s Ferronis is by far the more dangerous opponent and he also has more HP than Ethel’s Ferronis, therefore you want to target her first. Ethel may only have two Arts available to her but her auto-attack is quick, and she uses both of her Arts with great frequency. Both Merciless Dance and Tempest’s Edge are very similar Arts that deal the same damage based on how many of the strikes connect.

The larger threat when fighting against Ethel, ironically, is Cammuravi, as he’ll often be striking you at the same time while also inflicting Blaze. This makes Ethel’s Arts deadlier as she can leave you with half of your HP before Cammuravi inflicts the debuff on you. For this reason, try to control an Attacker with positional Arts from the side or back, that way you can avoid most of the attacks from both of the Ferronis.

Both of your opponents are, believe it or not, susceptible to Combos, and you’ll want to find a way of performing as many as possible as putting even one of them out of commission for a time will give you the time to recuperate a little from the non-stop onslaught. With you focusing the entire party on Ethel, it shouldn’t take too long to remove her as a threat from the battle.

It’s far from over, however, as Cammuravi has powerful Arts including Heaven’s Fire Bloom which will strike everyone in front of him, usually the entire party save for your controlled character. Conflagration Blade is his most used Art and it will inflict Blaze on top of the moderate damage, so you’ll want to have the means to remove debuffs for this battle, Valdi’s (or the War Medic Class) Cure Bullet Art is perfect for this situation.

Interestingly enough, unlike Ethel’s Ferronis, Cammurvai’s Ferronis needs to charge all of its Arts before using them, often giving you time to use a Combo to hopefully prevent him from getting the Art off. This becomes more of an issue though once you push him into Enrage. The Arts will come more frequently, and the charge time is a lot quicker, if you have a Chain Attack available to you at this point, try to use it and end it with Noah and Mio’s Ouroboros Chain to cause massive amounts of damage and hopefully end the battle before it becomes more of an issue.
