How To Play Keelan In The First Descendant
Keelan’s playstyle revolves around speed and relentless dashing, as well as timing his skills correctly, like Acidic Decay, to maximize his DPS. His skill set includes several active abilities that synergize well with his fast movement. Here’s what each of them do:
- Void Corrosion: A ranged ability that fires a corrosive projectile, inflicting Acidic Decay on targets. If an enemy already suffers from Acidic Decay, this skill deals bonus damage.
- Onslaught: His signature dash ability that allows him to charge forward, piercing enemies and spreading Acidic Decay. When Onslaught ends, an explosion deals extra damage to nearby foes.
- Septic Gust: A close-range skill that inflicts Acidic Decay and triggers Blood Rot on enemies, ending with an explosion.
- Tremor: A situational ability that either amplifies Onslaught stacks when no Acidic Decay is present or deals damage based on existing stacks.
- Erosion (Passive): Increases his Acidic Infusion Level with repeated skill use, granting an Agility effect that boosts his movement speed.
Best Keelan Build in The First Descendant
The ideal Keelan build focuses on maximizing his high skill power and rapid dash abilities while increasing his survivability. Most of his builds are centered around his core ability, Onslaught, which allows him to pierce multiple enemies and trigger devastating explosions.
By stacking Acidic Decay with Void Corrosion and combining it with Tremor, Keelan can eliminate both hordes and Elite Vulguses. By focusing on these skills, you get a build that not only dishes out incredible DPS numbers, but also keeps Keelan on the move, making him hard to pin down, especially in modes like Void Intercept battles.
Best Modules For Keelan
For optimal performance, you need to acquire and equip modules that amplify Keelan’s skill power and reduce cooldowns. The recommended modules for Keelan include:
- Mobile Strike (Transcendent Module): Replaces the Septic Gust ability with Hunting Time, granting an Adventurer’s Spirit buff that prevents Onslaught stack reduction for a brief period. This effect allows Keelan to dash continuously, so it’s a must-have.
- Focus on Toxic: Boosts Toxic Skill Power and reduces skill cooldowns, ensuring that Acidic Decay is applied consistently.
- MP Conversion: Reduces skill cooldowns further, critical for maintaining a high frequency of attacks. Decent DPS increase.
- Nimble Fingers: Provides an additional reduction in skill cooldowns, keeping Keelan’s skills ready to cast at all times.
- Stim Accelerant and Increased HP: These modules enhance Keelan’s overall survivability, granting him extra HP to withstand counterattacks.
- Singular Amplification: Increases Keelan’s Singular Skill Power Modifier and enhances his overall damage output without compromising his mobility.
With a well-balanced module setup like the one mentioned above, you can not only increase Keelan’s damage potential, but also ensure that he can sustain his rapid dashes and high-frequency skill usage.
Best Weapons For Keelan
While Keelan’s build revolves around his abilities, his weapon remains an integral component of his damage output. The recommended weapon choices for Keelan include the following:
- Voltia (Beam Rifle): Ideal for its unique Chain Current ability, which deals extra damage to enemies with Anti-Void Shields. Voltia offers high Firearm ATK and an effective range that complements Keelan’s dash-centric combat style.
- The Final Masterpiece (Handgun): Provides a significant boost in movement speed and is useful for quickly killing Vulguses without having to use multiple shots.
- Afterglow Sword (Sniper Rifle): While less common in Keelan builds, it serves as an alternative for long-range fights, especially against Elite Vulguses and Void Intercept bosses.
These weapons should be changed based on your preferred playstyle. But, if you’re looking for the overall best, then Voltia stands out as the optimal choice.
Best Weapon Modules For Keelan
Choosing the right weapon, though important, isn’t the final straw. You still need to enhance it with the right modules that maximize its damage output and efficiency. For example, when equipping Voltia, consider the following modules:
- Rifling Reinforcement: Boosts Firearm ATK by up to 12%, making each shot more powerful, with a solid DPS increase.
- Action and Reaction: Increases Firearm ATK significantly (+15%) while adding a slight recoil penalty, which is negligible given Voltia’s balanced fire rate.
- Concentration Priority: Provides a massive boost to Firearm Critical Hit Damage (up to +47%) while reducing reload time by 30%, ensuring that your shots hit hard when it matters most.
If you want to equip more modules or have capacity left, try to equip the ones that enhance fire rate or add critical hit modifiers, depending on your personal preferences and available choices.
Best Reactors For Keelan
Finally, Reactors play a vital role in amplifying Keelan’s skills by boosting his Toxic and Singular Skill Power. For the best overall performance for Keelan in The First Descendant, the Toxic Singularity Reactor is highly recommended. It optimizes both Toxic and Singular Skill Power, ensuring that abilities like Onslaught and Void Corrosion deal maximum damage. It also increases Skill Power while also contributing to cooldown reduction. Plus, it also supports Keelan’s overall DPS and high-frequency skill usage.
