Source of Water > Tactical Analysis

Mika's best build is fairly simple as she only needs to focus on increasing the amount of wave stacks she gains and healing cards. She can be built in many ways without losing her identity of making the party stay alive with her heals and supplying characters with AP to use their expensive cards that it is highly advised to aim for a divine epiphany to one of her cards and duplicate it.

She is best suited with the 2/2/2 set consisting of Healer's Journey, Tetra's Authority and Seth's Scarab to further increase her healing output. Her favored chaos zone is Laboratory 0 to get her best equipment such as Overcurrent Shock Unit to deal fixed damage after drawing a card if you ever get the divine epiphany for it. Fragment of the Empty Void to get a better starting hand at the start of the battle and Superconductive Protein for a single card discount down to 0 AP at battle start.

Main DPS	Sub-DPS
Tressa	Cassius

Out of all the possible team combination for Mika, her highest performing team that utilizes her cards efficiently is Tressa and Cassius. This team revolves around generating Shadow Daggers for Tressa when the upgrade epiphany of Shadow Reload is active after each healing card used by Mika then utilizing the Triple 0 quest Cassius provides to gain morale, draw cards and use additional attack cards to stack more Agony when Curse and Cursed Gouge is active.

List of All Characters

Can FIt in Any Team Comp

Mika and her playstyle revolving around healing and AP recovery makes her a perfect fit to any team that needs a healer on their side. This also makes her the top choice for higher difficulty chaos runs as she can make the party healthy all from start to finish without having to worry about mental breakdowns ending your run.

Mika Best Cards

Click on a Link to Jump to a Section!
Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Card	Explanation
Source of Water	AP Cost: 1: Type: Skill ・Heal 150% ・+2 AP ・On Recover, cost of card -1 for 1 turn
Blessing of Waves	AP Cost: 1 Type: Skill Tags: Retain ・Heal 150% ・+30% Healing equal to number of AP ・1 Wave
Tactical Analysis	AP Cost: 0 Type: Skill Tags: Retain ・Heal 50% ・1 Wave ・For 2 turns, +50% Heal

You want Mika's Source of Water to turn into a 1-cost epiphany that will reduce its cost down to 0 when you heal a portion of your health and gives you 2 AP instead of only 1. Do note that healing at full HP does not activate the recovery effect of this card.

Blessing of Waves is best when it has the epiphany version of it gaining 1 stack of Wave to progress it and give the party more AP while Whirlpool is better removed because any epiphany of it is not useful for this team and does not activate Shadow Reload.

Tactical Analysis on the other hand, should have the epiphany that adds an effect of a heal so that it can activate Shadow Reload at 0-cost even if it does not heal that much. This will ensure that you can keep on generating Shadow Daggers with ease.

List of All Cards

Essential Team Cards and Epiphanies

Tressa Cards	Explanation
Unsheathe Dagger	AP Cost: 0 Type: Skill ・Create 2 Shadow Dagger
Curse	AP Cost: 0 Type: Skill ・For 2 turns, when using Attack Cards, 1 Agony
Shadow Reload	AP Cost: 1 Type: Upgrade Tags: Initiation ・When Healed by a Skill Card, create 1 Shadow Dagger
Vital Attack	AP Cost: 2 Type: Attack ・80% x 3 Damage ・For 1 turn, +50% Agony Damage
Cassius Cards	Explanation
Pop Eyed Popper	AP Cost: 0 Type: Upgrade ・From 4 Quests, choose 1 to begin
Devil Dice	AP Cost: 0 Type: Attack ・Draw 1 ・80% Damage to all enemies equal to that card's cost
Dice Trick	AP Cost: 2 Type: Upgrade ・On Quest completion, create 1 Quest Card(s)

Tressa's entire kit revolves around her having multiple copies of the upgrade version of Shadow Reload to gain multiple copies of Shadow Dagger for each healing card used. She also needs the increased Agony damage epiphany for Vital Attack to significantly increase the damage of all applied Agony to the enemy for 1 turn.

Cassius job in this team is to ensure that he can always choose the correct quest when playing Pop Eyed Popper and making sure that Dice Trick has the epiphany to create more quest cards after quest completion to increase the odds of getting more card draw and morale buffs.

Mika Best Partner

Click on a Link to Jump to a Section!
Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Partner	Details
Nyx	Passive Effect: Errante Hurricane - The assigned combatant's HP and healing are increased by 8%. When the assigned combatant Draws for the first time each turn using an ability, +8% Damage dealt by allies for 1 turn. Ego Skill: Resonance - Discard up to 3 cards, then Draw +1 cards equal to the number discarded

Mika's best partner is Nyx as she can provide more max HP and healing output alongside the ability to give the party more damage boost after drawing a card for 1 turn. She also has the ego skill of discarding up to 3 cards and drawing that many cards to ensure that you will have the best hand.

However, she is part of the Arkhianon Supply which is the battlepass of this game, and the only way to get her is to pay for it with real currency.

List of All Partners

Alternative Budget Partners

Partner	Explanation
Arwen	Arwen is a decent 4-star Partner alternative that provides damage reduction when an enemy is about to attack and make your healing scale a bit better with the healing increase she provides.
Yvonne	A 3-star controller partner alternative that has an on demand healing and fortitude with her ego skill and provides a massive amount of defense buff to the wearer which increases Mika's healing output.

Mika Best Memory Fragments

Click on a Link to Jump to a Section!
Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

The optimal Memory Fragment combination for Mika pairs the Seth's Scarab and Healer's Journey sets, while Healer's Journey is an optional set to further increase our survivability. Seth's Scarab is the best set for Mika since this provides a huge boost to Basic card heals by 20%, while the Tetra's Authority will give us more Defense as this scales with her healing as well.

List of All Memory Fragments

Stat Priority

Main Stats	Recommended Substats
Ideal: Health% Desire: Health% Imagination: Defense%	・Defense% ・Defense ・Health ・Ego Recovery

For stats, you want Mika's stats to be as defensive as possible. Defense lets you scale your heal value higher which makes every heal move more efficient and lets you focus on other cards to use during battle and Health increase the max HP of your party. You can sprinkle in a bit of Ego Recovery for her substats as she scales her healing with it too due to her potentials but it is not truly needed.

Mika Best Equipment

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Weapon	Armor	Accessory
Overcurrent Shock Unit	Fragment of the Empty Void	Superconductive Protein

Mika's best equipment can only be found in Laboratory 0. Her choice of weapon is Overcurrent Shock Unit to deal fixed damage after drawing a card assuming you get a draw divine epiphany for her otherwise, she doesn't really have anymore equipment that can fit her in Laboratory 0. Fragment of the Empty Void to get a better hand at turn start by discarding up to 3 cards and drawing that many and Superconductive Protein for a single card discount down to 0 AP at the start of battle.

List of All Equipment

Alternative Budget Equipment

Weapon	Armor	Accessory
Flashbang	Titan Combat Suit	Magic-Infused Sapphire

If you aren't able to get the best, you can settle for these equipment that can be found in any chaos zone inside shops. Flashbang for the start of battle 3 stacks of Weaken to a single enemy or randomly spread to multiple enemies. Titan Combat Suit for extra healing after getting hit. Magic-Infused Sapphire to instantly reduce a full bar of tenaciy to all enemies at battle start.

Duplicate Divine 0 Cost Cards

Generate Wave Stacks for More AP

Always Remove her Attack Cards

Duplicate Divine 0 Cost Cards

Since you will always use her in chaos runs, we recommend trying to get a save data for her with a draw 1 divine epiphany on either Source of Water or Tactical Analysis then duplicate it when you get the chance as this will greatly enhance her usefulness in many teams.

Generate Wave Stacks for More AP

Mika specializes in making use of the Wave buff, which allows her to generate an Action Point on the 3rd stack. This is incredibly useful for setting up a wide variety of team compositions to continue using high-value cards due to your high AP count.

Excess Wave Stacks Carries Over After Reset

For example, if Mika has 2 out of 3 wave stacks and used a card that grants her 2 wave, the team will gain 1 AP and reset her wave stacks and the excess wave will be carried over.

Always Remove her Attack Cards

Chaos Zero Nightmare - Whirlpool Remove
Her basic attack card and Whirlpool doesn't have any use in any of her builds or team composition as she doesn't much of an attack stat. It is better removed so that Mika can cycle through her cards much faster and avoid clogging the deck.
