Bunny’s Exclusive Equipment

Instead of exclusive equipment, Ultimate Ajax has his ultimate equipment, the Territory Defense Specialized Battlesuit ‘Belief’.. You can access it by clicking details in the Descendant menu and customizing the appearance of his battlesuit. Below are the details on Ultimate Ajax’s Ultimate Equipment:

“The pinnacle of personal defense, the remains of this Ultimate equipment, ‘Belief’, were discovered in an Ancestors’ facility in the Agna Desert. As it stands, they reconstructed as much of it as they could based on those remains and the fragmented blueprints. However, given its overwhelming power, despite its low reproduction ratio, the Magisters speculate that the original version of this Ultimate equipment was fitted with a battlesuit that rivaled that of a Colossus. The problem is, no one knows what defeated the Ancestors who donned such powerful suits.”

Ultimate Ajax Skills

The Ultimate Ajax build centers around building up Void Energy by using skills. You have three bars, which, once filled, enhances abilities. While leveling, you will mainly use Expulsion and Void Walk for damage, then Orbit Barrier and Hypercube for survivability. In Void Intercept battles, your main objective is to hold aggro on the boss while shielding you with a wall and bubble your allies. Using three skills enhances your next, but you don’t want to run out of MP. Therefore, always keep enough to cast an Orbit Barrier when you are in trouble and need to relieve pressure. Below are the skills of Ultimate Ajax’s character:

Best Skill for Ajax

Orbit Barrier is the best skill for Ultimate Ajax due to its low cooldown, damage reflection, and expandable range, providing significant utility and survivability. This skill scales with your defensive stats, making high DEF and HP crucial for Ajax. Additionally, unlike Kyle’s wall, Orbital Barrier is instanced, allowing you to place it while reviving an ally or taking a break from incoming damage.

Ajax’s unique resource system allows him to enhance skills through Void Energy and skill usage. To maximize this, use mods that reduce cooldowns so you can frequently cast skills and build energy. On Ajax’s default UI, three lines in the yellow sections indicate 33% increments of Void Energy, corresponding to singularity levels. When you reach 100%, your skill bar turns blue, granting an enhanced ability.

By using Orbital Barrier to generate Void Energy, you can then cast Hyper Cube when enhanced. The Enhanced Barrier from Hyper Cube boosts Firearm ATK and Explosive ATK within a 4-meter radius. This radius can be further expanded through mods, significantly increasing both range and cooldown, thereby enhancing damage and survivability for you and potentially your teammates.

Use Orbit Barrier defensively and as a feeder to enhance your skills. For optimal results, pair Ajax with a Non-Attribute reactor and focus on cooldown reduction, increased DEF, and skill range increase.

Orbit Barrier

Orbit Barrier Features for Ultimate Ajax in The First Descendant:

Like many shield skills, use it whenever you face large groups of enemies or need to provide reliable cover for yourself and your allies. Enhance its effectiveness by deploying it when you have full Void Energy. With its low cooldown and long duration, this skill boasts high uptime, so don’t wait for the perfect moment. Deploy it as needed for cover and safety. Lastly, you can deploy the shield once enhanced to increase its strength, giving you more time to stay safe.

Void Walk Features for Ultimate Ajax in The First Descendant:

How to use Void Walk:Utilize Void Walk as your primary crowd control skill. It stuns enemies and keeps them locked down, enhancing your survivability. Using this on a group of low-health enemies keeps them together, allowing your damage-dealing allies to eliminate them quickly. Void Walk can serve as an area-of-effect damage source or a defensive stun.

Expulsion Features for Ultimate Ajax in The First Descendant:

How to use Expulsion:This skill is Ajax’s highest damage ability and offers additional utility by knocking enemies back. It’s excellent for eliminating foes or keeping them away from you and your allies when health is low. Pair this with a follow-up stun for a potent crowd control combo that both knocks back and stuns enemies.

Hyper Cube

Hypercube Features for Ajax in The First Descendant:

How to use Hypercube:Hypercube is one of the best skills in Ajax’s kit, which is why it has a long cooldown. Use it when enhanced for team damage buffs and utility. It’s ideal for boss damage phases or tackling other high-health targets. The skill provides additional survivability and security for you and your allies, and the damage boost is automatically applied when used in its enhanced state.

Event Horizon (Passive)

Event Horizon Features for Ajax in The First Descendant:

How to use Event Horizon:Your goal should be to consistently use your skills to maintain high singularity levels and maximize their benefits. Ensure your energy is at its peak, especially before using Hypercube skills, to guarantee that your protective dome provides a free damage boost for you and your fireteam. Unlike other passives, Event Horizon doesn’t require complex combos or skill management to be effective. Simply casting your skills will build up your levels, reducing cooldowns and enhancing your skills’ effectiveness.

How to play Ultimate Ajax in The First Descendant

To play Ultimate Ajax effectively, adopt an aggressive tank role by engaging enemies directly, drawing their attention, and allowing your allies to eliminate them. Mastering his kit involves moving around the battlefield and offering cover to your team while maintaining enemy aggression.

Ultimate Ajax has two variations of skills: the base version and the enhanced version. Build up Void Energy by using your normal skills. Once Void Energy is full, your skills become enhanced with additional effects. For instance, both shield skills gain damage reflection. Managing Void Energy efficiently is crucial; mastering this aspect unlocks Ultimate Ajax’s full potential.

Shields:Ultimate Ajax’s main strength lies in deploying shields and barriers. These shields provide cover for yourself and your allies, and when enhanced, they can reflect damage back at attackers. Ajax has two different shields: the basic Orbit Barrier, a rectangular shield wall that blocks damage from enemies on the other side, and the Hypercube shield, a massive dome that allows allies to move in and out for safety.

Unlike other characters, Ultimate Ajax focuses on controlling and restricting enemy movements rather than outright eliminating them. As content becomes more challenging and enemies have more health, this control becomes increasingly valuable, reducing the damage pressure on your team. Ajax can stun and knock back enemies, providing essential crowd control.

As a support-based crowd-controlling tank, dealing damage is not your primary role. However, you can still contribute with your weapons and skill damage. Prioritize weapons that apply debuffs to increase your team’s effectiveness. While your skills won’t clear out entire hordes, they should be used whenever possible to assist your teammates.

Ultimate Ajax Story in the First Descendant

The Ultimate Descendant Project refers to a plan in which either the Ancestors’ technology and equipment found throughout Ingris, or their special Arche genes, are refined to suit the characteristics of active Descendants, then applied to them. The ultimate goal being to enhance all Descendants to reflect the Ancestors, the powerful predecessors of humanity.

Ajax responded enthusiastically to this Ultimate Project. Originally, the battlesuit used by Ajax was created for Void exploration, but performance-wise, it’s true it did not meet expectations. Therefore, in anticipation of the inevitable Void exploration, Ajax needed a measure of protection which could operate in a stable manner, even in uncharted environments. He had high expectations that the Ultimate equipment would be the breakthrough he had been searching for.

As if to answer Ajax’s convictions, the Ultimate equipment named “Belief” completely exceeded the Liberated Guardian’s expectations. Forged with the Ancestors’ technology, the enhanced Kuiper battlesuit covered the wearer like an impregnable fortress. Despite its bulk, the Arche reactive coil equipped on each part would pick up the user’s Arche signals, supporting movement, and even ensuring outstanding mobility. Moreover, the Magisters successfully transplanted the Void Energy, which had been absorbed into his existing battlesuit, to the Ultimate equipment, modifying it so that it could also utilize Ajax’s Arche ability. “Belief” became an equipment truly meant for Ajax in every sense.

Ajax faith in this Ultimate equipment was unwavering. With it, he would be able to conquer the Void and find Aisha. This is the unshakable belief that Ajax possesses, just like the name of this equipment.
