Walkthrough

Unbound: Chalteaufite Cravenscreed

You will be accompanied by Kaqool Ja the Repentant during this battle, which consists of defeating members of Chalteaufite's gang before taking on Chalteaufite himeself.

At the start, only an Unyielding Mettle barrier covering a Craven Follower in a magitek reaper is targetable. It will have the Unbroken Mettle buff, causing your attacks to deal very little damage.

Homing Laser: The untargetable magitek reapers in the background will aim one telegraphed line AoE at you and one at Kaqool Ja, dealing magical damage. Spread out to avoid overlap.
Missile Storm (no cast bar): Instant room-wide magical damage. This is used repeatedly throughout the battle.
Multiple circle AoE telegraphs will appear, while the adds will use Homing Laser at the same time.
After some time, the barrier will become damaged, and a blue circle will appear at a point on it, indicating a weak point. Attacks should be directed when directly facing the blue circle so the barrier will take normal damage. These will also be represented by different status effects: Fractured Mettle and Backward/Leftward/Rightward Fracture.

After destroying it, the Craven Follower will retreat, and the three other magitek reapers will enter the arena and become targetable. These will all initially have the Unyielding Mettle barrier and take very little damage.

Kaqool Ja will use an AoE that will damage all of the barriers, giving them weak points in different directions.
The barriers can then be destroyed again by focusing attacks the weak points.
The single magitek reaper in the background will use Magitek Cannon, a telegraphed magical spread AoE on you, while circle AoE telegraphs also spawn.

After destroying the three additional barriers, six Magitek Missiles will spawn, three tethering you and three tethering Kaqool Ja, and will gradually move towards the tethered targets. Contacting the ones that you are tethered to will result in high damage. The adds have very low health and can be dispatched in 1-2 attacks.

Chalteaufite will replenish the barrier on the four magitek reapers.
Additional sets of Magitek Missiles will spawn, which should be defeated. Meanwhile, one of the reapers will use a telegraphed large circle AoE in the middle of the arena, which will consume its barrier.
Another set of missiles will spawn, while the three remaining magitek reapers will each use a telegraphed circle AoE, leaving three small safe areas.
With their barriers gone, the magitek reapers will become targetable and should be defeated.

Chalteaufite himself will now enter the arena. He will be piloting a Prometheus magitek and have an Unyielding Mettle barrier.

Heavy Surface Missiles: Eight magical proximity AoE markers will spawn in four sets of two. Move away from the first two and rotate to move away from the remaining ones.
Guns Blazing: Chalteaufite will aim 90 degree telegraphed conal AoE at you, which can be dodged. This is followed by a telegraphed 270 degree AoE hitting the previously safe area.
Ruthless Bombardment: Chalteaufite summons multiple small and large circle AoE telegraphs, leaving some safe areas.
After some time, Ceetol Ja will tether and empower Kaqool Ja, who will keep attacking the barrier.
Magitek Missiles will spawn and move towards Kaqool Ja, which should be destroyed to protect him.
The player will also be targeted with circle AoEs at their current position. It is fine if these hit Kaqool Ja, as they do negligible damage.
Kaqool Ja will then use a strong attack that will crack the barrier and give it a weak point, allowing you to focus attacks on it. Ceetol Ja will also give you a Shining Encouragement buff, increasing damage dealt.
After destroying the barrier, Chalteaufite will become targetable and can be easily defeated, as he has low health. He will use Raging Artillery, dealing continuous hits of magical damage.

Journal

Ceetol Ja steels herself for the final confrontation with Chalteaufite.
You receive word from your men on the inside that Chalteaufite and his gang will soon begin their assault on Ala Mhigo. Just as you are preparing to leave, Kaqool Ja once again demonstrates his knack for being in the right place at the right time, and offers his services in the upcoming battle. Glad to have the mercenary's axe, you and Ceetol Ja prepare for the final confrontation with Chalteaufite.
You arrive in the nick of time, as Chalteaufite's gang have yet to reach their intended target, the Royal Palace. As their caravan loaded with magitek weaponry cannot traverse the various flights of stairs throughout the city, Ceetol Ja suggests taking a shortcut and intercepting your foes.
Now that you are ready to spring your ambush and cut off Chalteaufite's advance, Ceetol Ja awaits your signal to attack. Although your foe possesses not only the Steelhog Vessel but an untold number of magitek warmachines, you and your comrades cling to the hope that the key to victory will yet present itself.
Remembering that “Even the mightiest shield will eventually crack,” you succeed in shattering the artifact's barrier and Chalteaufite's dreams of world domination along with it. Now that the Steelhog Vessel is back in Ceetol Ja's hands and the gang members clapped in irons, you take a moment to savor your triumph.
After the battle, Kaqool Ja reveals his intention to repent for his crimes by turning himself in to the authorities. He also wishes one day to apologize to the members of Ceetol Ja's village for the harm he has caused using the artifact, should he ever have the opportunity to visit. Ceetol Ja herself welcomes the idea, but for now, there are more immediate concerns, such as returning to Tuliyollal to present Raholl Ja with the Steelhog Vessel.
As one might expect, Raholl Ja is thrilled by the safe return of the vessel, yet even that is overshadowed by the joy of reuniting with his granddaughter after her perilous mission overseas. Now that the artifact has been retrieved, the villagers can resume hunting in the forest without fear of being devoured by monstrous creatures. Ceetol Ja offers her heartfelt thanks and bids you farewell until chance or fate brings you together once more.
