In Armored Core 6: Rubicon Fire, players will be joined by the mysterious Rubicon 'Al'. After being contacted in the final mission of Chapter 1, she becomes a loyal ally for most of the game's story. She remains an ally in the two routes players can take in the game, but becomes the final boss in the "Raven's Fire" ending route.
Player Day Roll video continues the content In Armored Core 6's "Raven's Fire" route, players will have to confront Ayur as she commands Academy AC to fend off Xylem and stop the Warlord from burning coral. Aiur's AC is unbelievably fast and can do incredible damage with Coral weapons, making the final challenge excellent.
attack
:
Issue 1
Al can fire homing coral projectiles, best avoided by quickly strafing left or right, and she tends to fire them right after boosting. Use a quick boost to get away from them if necessary.
El will dash around and try to close the distance so she can use her Coral Blade to shred the player's AC. These can be dodged by quickly accelerating diagonally and past her, aiming for the side of her that isn't firing the energy blades. She can combine those slashes and alternate arms, so players who don't have the energy or time to maintain a quick boost might consider keeping distance and using the quick boost to stop Al from getting close enough.
Elle also fires explosions from her Coral Rifle, which can be avoided by strafing to the sides. In this particularly brutal boss fight, El's final attack is to transform her AC into her bird-like form and charge at the player. Charges can be evaded by quickly propelling to the left or right, or by hopping with reverse-jointed legs. Avoiding this charge is a priority as it can cause incredible damage.
Stage 2
After reaching half health, El will enter Phase 2 (indicated by a brief slow motion) and rapidly accelerate away from the player. El will then create two red copies of himself in the air and charge towards the player with his coral blades. These can be dodged by quickly pushing forward to slide between the two slashes. El will use his Charge Slash after this attack, which can be dodged just like the first phase of the melee combo. She will continue to use this attack regularly throughout the second phase.
After this, Al will continue using the attacks from the first phase and start using some new tricks. The first move has her perform a transformation dash like the first phase, but now with a dangerous follow-up attack. This can be dodged by quickly pushing to the side or jumping over it. After the first dash, she will circle and create several red AC clones that charge the player and explode. These can be dodged by strafing and boosting in the direction opposite to the direction she is flying. She'll then charge herself, which can usually be dodged by continuing to strafe sideways or a quick boost to the side (if that looks like her). Will still hit the player.
El can also now charge a red beam of energy, which does a lot of damage if connected. Players should watch for a buildup of red energy on her gun, which indicates she's charging for an attack, and then quickly push sideways to avoid it when she's done charging. Al can also erratically dash into the air while firing explosive bullets. They detonate after a short delay, and it's best to back off and keep moving while she does so.
strategy
El has pulse armor in the first phase, and players need to break through this armor to deal damage to her. Pulse armor works best with rapid-fire weapons (such as submachine guns), weapons that fire multiple projectiles at once (such as shotguns), and pulse weapons (a lesson learned in the early boss fight with Balthus). It's easiest to hit Al after she swings the Coral Knife, as there's a brief delay before she resumes her attack. After firing a charged blast in her second phase, she'll also leave herself open, allowing players to rush in and unload. Players fighting from a distance can keep shooting at her, but her high movement speed makes many attacks likely to miss completely.
El charges with her clone in the second phase, allowing her to attack after the real Al charges, so this is a good opportunity to focus on her.
Build Recommendations (Best Builds)
Players hoping to take down Al should carry weapons that fire quickly and/or fire multiple projectiles simultaneously. This will help cut through her Pulse Armor and make it easier to stagger her. The reverse-attached legs also help increase mobility and make it easier to dodge her quick attacks.

pulse armor
This version uses the shotguns in each hand to quickly break through Al's pulse armor in the first phase, and builds the ACS strain on her in two phases, allowing players to stun her with relative ease. Once stunned, players should rush in quickly while switching the ASHMEAD pile bunker to their left hand for a charged attack. These charged attacks deal incredible damage and can easily drain Al's health.
With reverse-linked legs, the build is able to jump and leap over Ayur's charge attack and Coral Blade's swing when necessary, providing valuable emergency dodge when the player's AC runs out of energy. Songbird is a great way to put extra ACS pressure on El when he stops moving after attacking. Pulse Armor is a useful extension that stops Al's homing shots if the player runs out of energy at the wrong time, and also refreshes the ACS strain gauge when activated to avoid shaking. Players can also swap it for Assault Armor to stun El when she gets close to melee attacks.
Armored Core 6 is available for PS4, PS5, PC, Xbox One, and Xbox Series X/S.
