Assessment

Kengo is a Charge Attack-based damage class somewhat similar to Rising Force. Kengo's primary role is to generate charge bar for the team, and output frequent charge attacks thanks to its accelerated charge bar gain and 200% max charge bar.

  (Can't be removed)
  Stacking: Special Buff is a powerful buff that guarantees double attacks and gives a 30% boost to triple attack rate as long as MC isn't hit. Due to that condition, you can maintain it almost indefinitely if you can keep MC from getting hit... but on the flip side, it loses much of its effectiveness against enemies with high multiattack rates or all-ally attacks. The upgrade at Master Level 30 provides Charge Bar +50%Instantly boosts Charge Bar by 50%
  Strength: 50% each use and therefore significantly increases the overall rate at which Kengo can perform charge attacks.

  (Consumes 60% of charge bar.): A strong nuke combined with a massive buff to charge attack damage and cap. The charge bar can make it a bit cumbersome to use, but it lasts for three turns so it's often possible to empower multiple charge attacks with one use. Becomes slightly less useful when the main character is already strongly pushing against the charge attack damage cap, however.

  Stacking: Special Buff, but other subskills will almost certainly be better value for the slot.

How to Play

Every time MC uses a Charge Attack, they gain 1 UnyouATK, multiattack rate, and charge attack DMG are boosted based on Unyou lvl (Can't be removed)
(up to 5)—a permanent buff that further boosts their combat specs. Kengo synergizes well with multiattack buffs and charge bar speedups/generation that allow it to charge attack more. Generally, Chain Bursts are helpful but aren't necessary, so Kengo doesn't need to wait to C.A. with the rest of the party.

Notable Main Weapons

Kengo wants to be charge attacking as many times as possible, as often as possible, as hard as possible. The best main weapons to suit Kengo for this purpose are bows or katanas that provide one or more of the following when wielded as a main weapon:

• Charge bar boosts such as Charge Bar +Instantly boosts Charge Bar by
  and Charged +Instantly boosts Charge Bar by
  Unaffected by charge bar gain effects, either to the whole team or just the MC
• Charge Bar Gain UpCharge bar gain is boosted
  
• Increased charge attack power through C.A. DMG Up (Stackable)Charge attack DMG is boosted (Stackable)
  , C.A. DMG Cap Up (Stackable)Charge attack DMG cap is boosted (Stackable)
  , C.A. DMG UpCharge attack DMG is boosted
  , C.A. DMG Cap UpCharge attack DMG cap is boosted
  etc
• Increased number of attacks in a turn as each normal attack provides extra charge bar. This includes Double StrikeAttacks twice each turn
  , DA UpDouble attack rate is boosted
  , TA UpTriple attack rate is boosted
  , Guaranteed TAGuaranteed triple attack regardless of Triple Attack Lowered debuffs
  etc

Main weapons that can provide Guaranteed TAGuaranteed triple attack regardless of Triple Attack Lowered debuffs
are an excellent combo with  No More DoubtGain Triple StrikeAttacks 3 times each turn
Duration: 1 turn .
(Consumes 40% of charge bar.).

If using Kengo for one-turn kill teams, then a different approach is preferable. Weapons with charge attacks that debuff the enemy DEF or buff the party attack specs are much better in that case. Boosts to charge bar or or multiattack will be useless as you will not be taking a second turn to use those buffs. If a weapon that buffs the party attack specs on charge attack is chosen, then Kengo's second charge attack that turn will become stronger due to the effect of the first charge attack.

• Class Champion Weapon
  • Unsigned Kaneshige: A strong candidate for main weapon in every element. The C.A. effect gives Charge Bar +10%Instantly boosts Charge Bar by 10%
    Strength: 10% to all characters after MC, filling their gauges by at least 20% per C.A. (since Charge Attacks innately gives +10% charge bar to following characters). (Note: While Kaneshige still works in One-Turn Kill teams (especially with Humanity Emblem), weapons that provide party-wide buffs or bonus damage on C.A. may be more beneficial for OTK setups.) The MC also gains charge bar faster than normal.
    • Devilry EmblemAll allies gain 30% Charge Bar Gain UpCharge bar gain is boosted
      Strength: 30%Duration: 2.5 turnsApplied during the attack phase.
      On the next turn, it'll have 2 turns remaining. upon MC using charge attack. Standout choice for regular use. Devilry's party-wide 30% Charge Bar Gain UpCharge bar gain is boosted
      Strength: 30%Duration: 2.5 turnsApplied during the attack phase.
      On the next turn, it'll have 2 turns remaining. is extremely beneficial for C.A.-based parties, especially when the party has a high MA rate. Note: Devilry's effect is treated as a character skill-sided buff and does not stack with similar effects from character skills, such as  PandemoniumGain 70% Charge Bar Gain UpCharge bar gain is boosted
      Strength: 70%Duration: 3 turns.—the strongest effect takes precedence.
    • Humanity Emblem significantly improves Chain Burst effectiveness, but you must take care not to have the MC charge attack on their own lest the emblem be wasted. Better than Devilry for one-turn kill teams, but you may simply wish to take another weapon instead.
    • Divinity Emblem provides significant bonus damage when above 100% charge bar, but to use this effectively you will need to turn off charge attacks, attack until you have 200% bar, then turn on charge attacks and use all your bar at once, then repeat the process. Manual charge bar management is key to success with this emblem. If you do not turn off charge attacks the bar will be used on the turn after the MC reaches 100%, using most of the bar and not dealing any bonus damage at all. Best used with characters with 200% bar so that their charge acquired whilst waiting for the MC to reach 200% is not wasted.
• Alternate "Gain Charge Bar on Charge Attack"-type weapons

Make sure this weapon is the best possible use you can get out of your Gold Brick before choosing to get it. - Assumes use of the γ Revelation or Δ Revelation skills.

    • γ Revelation gives 15% boost to C.A. DMG cap and all allies gain 20% Charge Bar Gain UpCharge bar gain is boosted

It may be difficult to get this weapon in the first place, and will be expensive to bring to its full power. Consider whether you can use a farmable replacement instead. - All allies gain Charge Bar +10%Instantly boosts Charge Bar by 10%
    Strength: 10% (and MC gets a random skill cooldown cut) on charge attack. The MC also gains charge bar faster.
  • Eight-Life Katana and descendants vary in usefulness depending on how far along they are upgraded
    • Initially, the Eight-Life Katana gives Charge Bar +20%Instantly boosts Charge Bar by 20%
      Strength: 20% on charge attack, and thus offers some use to a Light Kengo
    • Once upgraded to the Eight-Life Katana Sterling, the charge bar boost goes away and is replaced by a random skill cooldown cut, and is not nearly as useful for Kengo.

• Other Options
  • Autumn's Decline - Small uplift on charge attack as well as a boost to charge attack power.
  • Ameno Habakiri 🛑🛑This weapon requires many Gold Moons to acquire, and will realistically involve the use of several Damascus Ingots to uncap to its full potential.

Summon Synergies

• When set as a main or support summon, 4★ Bonito's call is the most reliable way to instantly reach 200% charge bar. Because its aura only affects Water allies, this strategy works best for Water teams but will be much less reliable, damage-wise, for other elements.
