Klein

Preferred IV: +ATK / -RES

A relatively straightforward build aiming to maximize Klein’s damage output in the Player Phase, particularly the power of his first two strikes. Accordingly, an Attack Asset is his ideal choice of IVs for this build, with the +3 Attack it provides essentially translating to a significant +6 damage boost given the nature of Brave weapons like Argent Bow. Providing him with accompanying buffs to his Attack stat in addition to potentially taking the Attack +3 seal is thus highly recommended as well to further augment his ORKO potential.

Weapon: Argent Bow (+Eff)

• Klein’s personal weapon, Argent Bow, functions essentially as an upgraded version of a regular Brave Bow, boasting slightly higher Might and a lesser Speed reduction. Combined with his decent base offensive stats, this weapon allows Klein to deal a substantial amount of damage with relative ease.

• Argent Bow also possesses the benefit of carrying built-in Chill Def through its unique weapon refine. This grants him immense flexibility in choosing a B slot skill, a characteristic which he can utilize to bolster his offensive potential even further through the use of other skills like Special Spiral.

Assist: Reposition / Flexible

Special: Draconic Aura / Luna / Blue Flame / Dragon Fang

• When utilized in tandem with Special Spiral, Specials with a cooldown of 3 will be able to activate in every round of combat following their initial activation, making them his strongest (and most consistent) options here. The choice of which to actually use, however, is largely up to personal preference, with each of the Specials available to him having their own share of respective strengths and shortcomings:

  • Draconic Aura scales well with this build’s strong focus on building upon his raw damage output, but it does require him to constantly maintain a reasonable level of Attack in order to be as consistent as other options. In simpler terms, this means that Draconic Aura’s overall effectiveness can suffer should Klein not be properly supported or invested in.

  • Luna can be especially helpful when facing off against particularly bulky foes who would otherwise pose a significant threat, but carries the risk of potentially producing reduced damage output increase if fighting against an opponent inflicted by Argent Bow’s built-in Chill Def.

  • Blue Flame offers Klein the highest damage potential of all the aforementioned options, but its adjacency requirement renders it somewhat difficult to utilize effectively in practice given this build’s offensively oriented playstyle.

• If providing him with enough support and investment such that Klein can consistently activate Heavy Blade against opposing foes, Dragon Fang can be taken instead and will similarly activate in every round of combat following its initial activation.

Passive A: Death Blow / Sturdy Impact

• Death Blow 4 (or if it is unavailable, Klein’s native Death Blow 3) is ideal due to its immense synergy with this build’s intended playstyle, granting him a massive boost to his damage output upon initiation.

• Sturdy Impact is a high investment option that can also be considered should one wish to make initiating combat much safer. In addition to providing him with a strong +6 Attack boost, Sturdy Impact imparts Klein’s survivability with a tremendous improvement through its additional +10 boost to his Defense stat and negation of his opponent’s follow-up attack upon initiation.

Passive B: Special Spiral

• Thanks to Klein’s inherent access to Chill Def through Argent Bow’s weapon refine, he can take Special Spiral as his chosen B slot skill instead. This enables him to heighten his damage output further through the unique ability to consistently activate Specials with relatively long cooldowns in each round of combat.

Passive C: Odd Atk Wave / Threaten Def / Flexible

• In addition to letting him to potentially provide team support on odd-numbered turns, Odd Atk Wave allows Klein to be considerably more self-sufficient. It is not entirely necessary for him to function properly, though, and can be simply replicated through team support should it be unavailable.

• On a budget, Threaten Def can be a decent option to similarly help increase Klein’s damage output, but it can be somewhat redundant given Argent Bow’s access to built-in Chill Def. Otherwise, any C slot that most greatly benefits his team can be used here.

Sacred Seal: Attack +3 / Heavy Blade

• The Attack +3 seal (or any of its variants) is a fantastic option to increase his offensive potential even more.

• If providing him with a substantial amount of support and investment to his Attack stat, the Heavy Blade seal can be taken instead to alternately enhance his damage output through faster Special activations.

Preferred IV: +SPD / -RES

Klein can also utilize a standard quad strike set-up to great effect. A Speed Asset is of the utmost necessity for this build as he will be entirely reliant on his ability to consistently perform follow-up attacks through normal means for his damage output.

Weapon: Argent Bow (+Eff)

Assist: Reposition

Special: Luna / Draconic Aura / Blue Flame

• For his Special, those with a three-turn cooldown -- such as Luna, Draconic Aura, and Blue Flame -- remain his strongest option as they all possess the capacity to activate in each round of combat, provided that he can land a quad strike; otherwise, such Specials will only activate in every other round of combat. The matter of which to actually take will ultimately boil down to a matter of personal preference and skill availability.

Passive A: Atk/Spd Solo / Swift Sparrow / Fury / Life and Death / Brazen Atk/Spd

• Atk/Spd Solo is a stellar choice of A slot skill, providing Klein with the means to maximize his offensive potential through its phenomenal boost to both of his offensive stats -- all without detracting from his overall bulk or requiring an extensive amount of additional set-up beforehand. It does come attached with a positioning requirement, however, this will generally prove to be inconsequential as he will generally be away from his allies when initiating combat regardless.

• If it is unavailable (which is understandable given its scarce availability), Swift Sparrow and Fury are considerably cheaper and inarguably more readily available skills that serve to similarly strengthen his combat prowess.

• Life and Death and Brazen Atk/Spd are decent options as well, though only if one is able to provide Klein with the prerequisite support necessary for them to be considered viable substitutes, such as pairing him alongside an ally equipped with Reciprocal Aid to instantly drop him into Desperation’s HP threshold.

Passive B: Desperation / Null Follow-Up / Chill Spd

• Desperation is the standard B slot skill for most offensive nukes sporting relatively low defensive stats and Klein is no exception. This skill provides him with the ability to potentially unleash four powerful strikes on his opponent before they even have the chance to counterattack once he reaches its HP threshold, ensuring that he will be able to engage in extended rounds of combat, regardless of how much damage he may have taken.

• Should one be confident in Klein’s ability to freely initiate combat without the use of Desperation, this leaves his B slot open to other alternatives, most notable of which being Null Follow-Up and Chill Spd. Null Follow-Up ensures that Klein can bypass the effects of skills such as Wary Fighter that would otherwise prevent him from landing a quad strike, whereas Chill Spd is especially useful in assisting the young archer take down opposing speedsters who would have otherwise been quite troublesome.

Passive C: Even Spd Wave / Spd Smoke / Flexible

• In addition to letting him to potentially provide team support on odd-numbered turns, Even Spd Wave allows Klein to be considerably more self-sufficient. It is not entirely necessary for him to function properly, however, and can be simply replicated through team support should it be unavailable.

• On a budget, Threaten Spd can be a decent option to similarly help increase Klein’s ability to perform follow-up attacks, though consistently landing its debuff via careful positioning can prove to be somewhat inconvenient. Otherwise, any C slot that most greatly benefits his team can be used here.

Sacred Seal: Darting Blow / Speed +3 / Atk/Spd 2

• Combined with the effects of other Speed-boosting skills, the Darting Blow seal allows Klein to perform quad strikes quite reliably, making it his ideal choice.

• Any of the other standard offensive stat-boosting seals, such as the Atk/Spd 2 seal, the Speed +3 seal, or any of their variants, may also be used her to similarly improve his combat prowess, albeit to a considerably lesser extent.
