Kayron's best build focuses on creating and exhausting a lot of Futility to increase the damage of his Black Hole and Echo of Futility cards to deal massive single-target damage. This build can be played two separate ways depending on how high the level of your Kayron's Manifest Ego.
For his Memory Fragments, our setup works best with a 4/2 set using Offering of the Void and Executioner's Tool. This lets you gain a 20% multiplicative damage if he exhausted a card which Kayron does frequently. The multiplicative buffs he get works a bit different on his cards as he can increase its base damage infinitely which makes the buffs stronger as you amp up its base multipliers.
His favored chaos zone is Swamp of Judgment to get his best equipment such as Dagger That Tricked The Shadow for a 12% critical damage buff. Fairy King's Crown to get a 6% critical chance for all of his attacks and Verdant Shackles for a 12% attack and defense stat boost which will increase his damage and healing.

 Mika
|
 Veronica
|
Kayron's best team retains Mika while replacing Nia with Veronica instead because of the exclusion of Eternal Hunger for the Season 2 content. Mika will provide all the AP Kayron needs while providing high amounts of heal if needed while Veronica will draw all the cards of both characters.
Alternative Team Members
| Character | Explanation |
|---|---|
 Nine
|
Can replace Veronica or Mika as a Sub DPS. Nine has the ability to exhaust cards other than her own cards and can help accelerate Kayron's scaling. She can also deal damage with her Hew but she lacks card draw and AP recovery. |
 Narja
|
Can replace Veronica or Mika as another Support. Narja can decrease the AP cost of your cards and can give additive buffs however she provides less AP and heals. |
 Nia
|
Can replace Veronica or Mika as another Support. She can draw cards and help deal more damage with extra attacks alongside damage buffs at maximum manifest ego level however she cannot use her Eternal Hunger combo for Season 2 content. |
 Rei
|
Can replace Veronica or Mika as another Support. Despite her additive buffs, she can still significantly increase Kayron's damage and thin out the deck if you have her at Manifest Ego 6 but you lose out on AP generation. |
 Cassius
|
Can replace Veronica or Mika as another Support. You can utilize his ability to cycle and find Kayron's cards as much as possible however most of his buffs are additive which Kayron does not utilize well enough. |

Unlike most characters, Kayron has many viable builds but his most effective and strongest build revolves around generating and exhaust Futility to scale two of his main cards and deal the highest possible damage in a single hit.
His choice of epiphany for Echo of Futility is the 0 AP version that can generate Futility at the cost of lower base damage but higher scaling potential and lower AP cost. You need to create at least 25 futility to reach the scaling potential of the other similar epiphany that cost 1 AP. After that, it will scale better.
For Brand of Annihilation, the best epiphany is the 7 AP version as you only need to exhaust 7 Futility for it to cost 0 AP for the entire battle while Black Hole should be the much stronger version of its base effect so that it scales much faster and higher.
As for Oath of Vanity, you either go for the epiphany with the initiation tag only if your Kayron has Manifest Ego level 2 or below, or the 180% Futility damage epiphany if you have him at Manifest Ego level 3 and above.

Mika's epiphanies and card choice is very standard where all she needs are cards that generate a lot of wave stacks to get more AP recovery. If possible, have at least one of her cards have a divine epiphany specifically card draw to help cycle the deck more.
As for Veronica, all she really needs is her Repose that has the epiphany of reducing its cost to 0 to draw 2 and Sir Kowalski with the draw 2 epiphany so that she can draw her own cards too.

 Bria
|
Passive Effect: Capable Secretary - The assigned Combatant’s Attack is increased by 8% When the assigned combatant generates a card, attack card damage is increased by 10% for 1 turn. Stacks up to 3 times. When the assigned combatant generates a Status ailment card for first time, +25% attack card damage for 1 turn Ego Skill: Check the Instructions - From the Discard Pile, Exhaust all Status Ailment (including cards changed from Status Ailment) and Curse cards. For each card Exhausted, +10% Designated Combatants' Attack card Damage for 1 turn |
Bria is the best partner for Kayron for the AoE Burst and the ability to exhaust all Futilities in the discard pile whenever you want. She can also buff damage multiplicatively, after creating Futilities and additively, when the created card is a status ailment.
After the Season 2 Balance, Bria gained the ability to boost the attack stat of Kayron making her more viable to use and cementing her place as the best partner for him.
Alternative Budget Partner
| Partner | Details |
|---|---|
 Eloise
|
If you do not have Bria, you can also use Eloise as an alternative as she can provide even greater multiplicative damage buff at max manifest ego level for Kayron at the cost of losing the ability to exhaust cards for her ego skill. |

Offering of the Void Set Offering of the Void Set When a card is Exhausted, increase Damage Amount of Void Cards by 20% for 1 turn |
Executioner's Tool Set Executioner's Tool Set +25% Critical Damage |
The best set combination for this build is Offering of the Void (4-piece) and Executioner's Tool (2-piece). You can trigger the Offering of the Void damage bonus very consistently, since Kayron's futility card always exhausts when used, and gives him 20% multiplicative damage buff.
This multiplicative buff that he gets aside from the memory fragment is useful for him because he can increase the base damage of his cards which can affect the damage increase of the buffs. For example, at base damage of 200%, a 20% multiplicative buff will raise it to 240%. However, if he stacked it to 440% base damage, then the same 20% multiplicative buff will raise to to 528% instead.
Stat Priority
| Main Stats | Recommended Substats |
|---|---|
|
Ideal: Critical Chance % Desire: Void Damage % Imagination: Attack % |
・Critical Chance %
・Critical Damage % ・Attack ・Attack % |
The main stat and sub stats Kayron needs are Void Damage, Critical Chance, Critical Damage and Attack. His last potential node needs at least 600 attack which is easy to achieve and the more you have attack stats on him the more critical damage he gets.

| Refinement: ・Increase Damage Amount of 2-Cost or higher Attack Cards by 25% ・Increase Damage Amount of Attack Cards by 20% ・Increase Damage Amount of Exhaust cards by 25% |
||
Kayron's best equipment can only be found in Swamp of Judgment with Dagger That Tricked The Shadow giving him 12% more critical damage for all of his attacks. Fairy King's Crown for 6% more critical chance so he can hit his crits more often. Verdant Shackles is the best trinket slot for him as it has +12% attack and defense boost which can significantly increase his damage and healing output.
His best choice for refinements is all about boosting his attack cards with multiplicative damage buffs. The 20% increase will affect all of his cards while both the 25% either can only buff the 2 AP or higher card such as Black Hole or the exhaust cards which can only apply to the Futility.
Alternative Budget Equipment
| Weapon | Armor | Accessory |
|---|---|---|
 Obsidian Sword Obsidian Sword Increase damage amount by 12% |
 Titan Combat Suit Titan Combat Suit When taking Damage, Recover 2% HP (1 per turn) |
 Amorphous Cube Amorphous Cube +25% Damage |
If you aren't able to get the best, you can settle for these equipment that some can be found in any chaos zones inside shops. Obsidian Sword to boost the overall damage of all his attacks by 12% multiplicatively. Titan Combat Suit to gain healing after getting hit once every turn and Amorphous Cube gives a permanent +25% additive damage buff to all of his attacks.

Manifest Ego 2 and Below Playstyle
Kayron's playstyle significantly changes based on the level of his manifest ego and whether he has access to Bria or not. If your Kayron is at Manifest Ego 2 and below, follow these steps to get the most of his cards:
- It is advised to get the epiphany for Oath of Vanity with the initiation tag for this playstyle.
- Generate Futility via Echo of Futility and Echoes of True Abyss to use it as an attack card while exhausting it at the same time.
- If you have 3 or more Futility in hand and you lack AP to use it, activate his Ego skill to exhaust it.
- (Optional) If you have Bria, only use her skill once you have 5 or more futility in your discard pile.
- Continue exhausting Futilities to strengthen your Black Hole and Echo of Futility.
Manifest Ego 3 and Above Playstyle
If you have Kayron at Manifest Ego 3 and above, his early turns will be different as your goal now is to setup the right turn to use his Ego skill or Bria's skill and exhaust a lot of Futility in your discard pile in one turn. Follow these steps to accelerate the amount of Futility you can exhaust:
- Since the epiphany of Oath of Vanity for this playstyle is not the one with the initiation tag, it is best to find it as soon as possible in your deck with card draws.
- If you haven't found Oath of Vanity, use your Echo of Futility and Echoes of True Abyss to generate Futility but do not use it.
- If you have found Oath of Vanity, play it and use as much AP to exhaust Futility while having enough to play other useful cards such as Black Hole or Echoes of True Abyss.
- Once you have 7 or more futility in your discard pile, you can use either Bria's skill or Kayron's Ego skill to exhaust it and get a massive damage boost to your cards.
- Continue exhausting Futilities to strengthen your Black Hole and Echo of Futility.
Existing Futility Does Not Convert to Attack Cards
Oath of Vanity converts Futility into attack cards but it does not make already generated and existing Futility into attack cards.
Black Hole and Echo of Futility Scales Infinitely
Most of Kayron's cards scales infinitely and adds the damage multiplier it gets once the condition is fulfilled to its base damage multiplier. What it means is that damage buffs especially multiplicative buffs will be affected by it so that the more you exhaust the higher the bonus damage you get from these buffs.
