Best Ajax build in The First Descendant: Skills, Weapons, Reactor & Modules

Master Ajax’s tank capabilities with optimized skills, gear synergy, and advanced strategies for The First Descendant

Understanding Ajax’s Role and Strengths

Ajax represents the pinnacle of tank support specialization within The First Descendant’s character roster, offering unparalleled defensive capabilities combined with strategic crowd control mechanics. Our comprehensive build analysis will help you maximize his potential in this demanding looter shooter environment.

In the current gaming meta, Ajax stands as an exceptional choice for players seeking a tank and support hybrid with robust crowd control features and battlefield dominance tools. Through extensive gameplay testing and optimization analysis, we’ve developed this definitive build guide to enhance your combat effectiveness.

While Ajax demonstrates limited direct damage output capabilities, this intentional design choice reinforces his specialized role as a protective force multiplier. Missions demanding pure DPS superiority may not showcase his strengths, yet he consistently ranks at the apex of tier lists for tank and support functionalities.

Our detailed recommendation encompasses the optimal Ajax configuration, including strategic skill applications, weapon synergies, reactor optimization, and module selections to transform him into an indomitable defensive bastion.

Optimized Skill Build and Rotation

Ajax demands strategic skill management since his effectiveness hinges on synergistic ability combinations rather than individual power. The optimal skill configuration prioritizes defensive utility while creating offensive opportunities for teammates.

Hypercube stands as Ajax’s cornerstone defensive ability, generating a protective dome shield that benefits both himself and nearby allies. This spatial manipulation technique creates safe zones during intense firefights or objective defense scenarios.

Shield resilience directly scales with Ajax’s maximum health pool, making HP stacking crucial for durability. The enhanced version introduces damage reflection mechanics, punishing enemies who attack the barrier with proportional defensive stat-based retaliation damage.

Despite his defensive orientation, Ajax significantly contributes to team damage output through strategic crowd control. Expulsion delivers area denial by forcefully repelling surrounding enemies, creating crucial breathing room during overwhelming engagements.

The upgraded Expulsion variant extends knockback range while simultaneously boosting Ajax’s maximum shield capacity, providing both offensive control and defensive reinforcement in a single ability.

Complete skill breakdown for strategic planning:

  • Event Horizon (Passive): Generates Void Energy through skill usage. At maximum accumulation, this energy enhances all abilities with additional effects and potency.
  • Orbit Barrier: Deploys a frontal shield with durability scaling based on HP and DEF statistics. Enhanced version reflects defensive stat-proportional damage to attackers.
  • Void Walk: Executes an aerial leap followed by ground impact that stuns nearby enemies. Enhanced variant temporarily increases maximum shield capacity.
  • Expulsion: Strikes surrounding foes with forceful knockback. Enhancement extends repulsion range and boosts maximum shields.
  • Hypercube: Creates spherical shield dome with HP and DEF scaling durability. Enhanced form reflects proportional DEF damage to barrier attackers.
  • Pro Tip: Master the skill rotation sequence: Void Walk for area stun → follow with Expulsion to create distance → deploy Hypercube for team protection during cooldowns. This creates optimal battlefield control flow.

    Weapon Selection and Synergy

    Optimal weapon selection for Ajax focuses on complementing his crowd control capabilities rather than raw damage output. The ideal firearms enhance his ability to lock down enemies and create strategic advantages.

  • Secret Garden (Tactical Rifle)
  • The Albion Cavalry Gun represents the premier choice for Ajax optimization. This specialized firearm creates perfect synergy with his skill set by delivering bonus damage against stunned targets.

    The Cavalry’s unique mechanic increases firearm attack power after striking stunned enemies. Critical hits against stunned foes apply additional stun effects, creating chain CC opportunities when combined with Ajax’s Void Walk ability for area denial.

    Strong alternative options include Secret Garden and the Tamer. Secret Garden receives stat enhancements when used during skill activation, while Tamer excels in prolonged boss engagements where sustained damage matters.

    Common Mistake: Avoid prioritizing pure damage weapons over utility options. Ajax’s value comes from enabling team success, not topping damage charts. The stun combo with Albion Cavalry Gun provides more team value than higher DPS alternatives.

    Advanced Gear Optimization

    Strategic reactor selection dramatically enhances Ajax’s performance by amplifying his core strengths. We recommend prioritizing these reactor options for optimal build performance:

  • Materialized Mechanics: Enhances Tech and Non-Attribute capabilities, with Non-Attribute specifically improving Skill Power ratios for greater ability effectiveness.
  • Materialized Phase: Boosts Non-Attribute and Dimensional attributes, directly strengthening Ajax’s barrier-focused abilities.
  • Understanding Ajax’s skill attribute distribution is crucial for reactor optimization. His barrier abilities (Orbit Barrier, Hypercube) utilize Dimensional attributes, while other skills (Void Walk, Expulsion) operate on Tech attributes.

    Optimal module configuration focuses on enhancing both defensive capabilities and team support functions:

    Matrix Recomputation transforms Expulsion into a team survival tool by applying protective buffs to allies, significantly increasing Ajax’s support value during critical engagements.

    Tech Specialist amplifies the offensive potential of Void Walk and Expulsion abilities, while additional modules provide comprehensive stat improvements across health, shields, and defensive metrics.

    The remaining module slots should accommodate specific elemental resistance needs for challenging content. Entering difficult encounters with appropriate elemental protection substantially improves survival rates and mission success probability.

    External Components represent the grind-intensive aspect of Ajax optimization, with benefits heavily influenced by RNG systems. Priority components should enhance:

    Ajax naturally possesses the largest health reservoir among all Descendants, but continued investment in this base statistic remains essential. Maximum shield enhancements complement this approach, combining with defense ratings to create comprehensive survivability.

    Expect extensive component farming with numerous suboptimal rolls before acquiring ideal attributes. This process embodies the classic looter shooter experience within The First Descendant’s progression systems.

    Advanced Tip: Balance your stat distribution between HP, DEF, and Skill Power. Over-investing in one stat diminishes returns—aim for approximately 40% HP, 30% DEF, and 30% Skill Power for optimal performance.

    Character Progression and Unlocking

    Ajax maintains an S-tier ranking in the current September 2024 meta following substantial buffs introduced with Season 1. Significant improvements to “Orbit Barrier” and “Hyper Cube” abilities now incorporate attribute resistance scaling, with barrier health and defense ratios receiving major enhancements.

    Void Walk and Void Charge abilities also received performance upgrades, establishing Ajax as an ideal starting character for new players. He ranks alongside Bunny, Lepic, and Valby for area clearance efficiency and mission completion speed.

    Unlocking Ajax follows the standard Descendant acquisition process requiring specific crafting materials and blueprint collection:

  • x35 Artificial Biometal
  • Ajax Enhanced Cell Blueprints
  • x408 Ceramic Composite
  • x30 Compound Carbon Activator
  • Ajax Stabilizer Blueprint
  • x402 Compound Coating Matierla
  • x462 Shape Memory Alloy

    Farming Strategy: Focus on Executioner and Swamp Walker intercept battles first—these provide the essential amorphous material patterns needed for Ajax’s core components. Farm these during bonus resource events for maximum efficiency.

    Advanced Playstyle and Team Dynamics

    Ajax delivers an exceptional experience for tank-oriented players who thrive on defensive gameplay and team protection. His unique capacity for self-preservation combined with damage reflection creates distinctive combat dynamics, particularly for players who excel at controlling engagement flow and safeguarding allies.

    His abilities centered on spatial manipulation and energy management appeal to gamers seeking sophisticated mechanics beyond simple damage dealing. This technical complexity rewards strategic thinking and precise ability timing.

    Team Role Execution: Position yourself at the front during engagements to absorb initial damage. Deploy Hypercube when teammates are vulnerable or during objective defense. Use Expulsion to create space when your team is overwhelmed or needs repositioning.

    Avoid These Mistakes: Don’t use Void Walk aggressively without team follow-up. Never deploy Hypercube in open areas where enemies can easily surround it. Avoid stat over-specialization—balance is key to Ajax’s effectiveness.
