Duplicate Priorities
Adagio > Nia's Curiosity

Nia's best build focuses on getting the right epiphany for discards on her cards to enable the Eternal Hunger combo that lets her reshuffle back the card and activate it multiple times to gain AP and 1 card draw. This makes her fit in any team that needs discard, draw and AP recovery.

She is best suited with the 2/2/2 set consisting of Healer's Journet, Tetra's Authority and Seth's Scarab to give her team more health and defense. Her favored chaos zone is Laboratory 0 to get her best equipment such as Overcurrent Shock Unit for more fixed shield after drawing cards. Fragment of the Empty Void to get a better hand at turn 1 by discarding 3 cards and drawing that many and Superconductive Protein for a single card discount down to 0 AP at the start of battle.

Nia Best Team

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Main DPS	Sub-DPS
Renoa	Rei

Nia's best team is Renoa and Rei. This team is all about discarding Dirge Bullets to activate its effects and buffing the damage with Rei and helping thin out the deck with exhausts. Nia's Ego Skill can also activate one of Renoa's combo that can dish out a lot of damage once you created a lot of Dirge Bullets in your deck.

List of All Characters

Can FIt in Any Team Comp

Nia can be a draw support for a lot of characters especially to those who needs to discard their cards. She also has a unique interaction with the Eternal Hunger forbidden card that lets her activate its effect multiple times in one turn with her cards which makes fit to any team that needs more draw and AP recovery.

Nia Best Cards

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Card	Epiphany Effect
G Chord	AP Cost: 1 ・1 Decibel ・Reveal the top 3 cards of the Draw Pile ・Choose one to activate
Mute Accent	AP Cost: 1 ・Discard all highest-cost cards ・The owner of those cards deals 100% Extra Attack on a random enemy
Soul Rip	AP Cost: 2 ・When discarding a card, 1 Decibel
Adagio	AP Cost: 0 ・Draw 2 ・Discard 2 ・With this effect, move discarded card to top of the Draw Pile
Forbidden: Eternal Hunger	AP Cost: 0 Tags: Retain, Exhaust ・Response: Draw 1, +1 AP

Nia's best cards revolves around getting the right Adagio epiphany to shuffle the Eternal Hunger forbidden card to the top of draw pile and activating its effects multiple times to get 1 AP and card draw.

Her choice of epiphany for G Chord is to have the ability to choose what card to activate from the top 3 cards of your draw pile while her Mute Accent must have the epiphany that discards all highest-cost cards to let her discard multiple copies of Dirge Bullets but for other teams, this is best removed.

As for her Soul Rip, it needs to be the upgrade version so that it thins her deck and it makes it so that she always has 5 stacks of Decibel.

She doesn't need to have the Eternal Hunger card on her deck. Any of her teammate can have it and having multiple copies from different party members can make her more efficient with it.

List of All Cards

Essential Team Cards and Epiphanies

Card	Epiphany Effect
Echo of Sorrow	AP Cost: 1 ・Create 3 Dirge Bullet cards
Instant Judgment	AP Cost: 1 ・At the end of the turn, 200% Extra Attack to the enemy with the lowest Health
Ballad of Pitch Black	AP Cost: 0 ・50% x 3 Damage ・For 1 turn, +100% Extra Attack Damage of Dirge Bullet
Flower of Devoured Fate	AP Cost: 0 ・Discard up to 3 cards from hand ・Generate that many Dirge Bullets
Resonating Darkness	AP Cost: 1 Tags: Unique ・+60% Damage of cards with cost 1
Snack Time	AP Cost: 0 Tags: Retain, Exhaust ・Heal 150% ・Draw 2
Dark Condensation	AP Cost: 1 ・For 1 turn, +50% Damage to Void attack cards

Renoa needs to have cards that generate Dirge Bullets consistently while being able to discard by herself to fuel her Dimensional Cube before it clogs up your deck. Rei on the other hand wants cards that buffs void attack cards before dishing out huge damage with Renoa so that all of her Dirge Bullets are buffed and not just one of her attack cards.

Nia Best Partner

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

Nyx is a 5-star Controller partner that boosts the party damage when a card is drawn. She also helps boost healing output which in this build is what Nia always does other than drawing and discarding.

List of All Partners

Alternative Budget Partner

Partner	Explanation
Arwen	Arwen is a 4-star Controller partner that heals and gives damage reduction to the party. She is generally good and a great option if you don't have Nyx.
Yvonne	Yvonne is the only 3-star Controller partner that boosts HP and provides healing to the party.

Nia Best Memory Fragments

There is no 4-set fit for Nia that is why generally good 2-sets are great for Nia. Healer's Journey for more max HP for the party she is in, Seth's Scarab for more healing output on her basic healing cards to help early game chaos runs and Tetra's Authority for more defense which results in more healing output.

Stat Priority

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

For both main stats and substats, aim for Health, and Defense. You can then go for more health and defense for her substats and include in some Ego Recovery to try and see if you can get the requirement for her last potential node. Otherwise, these are the only stats she needs as the extra attack damage that is stated in her cards are based on who initiates it and not Nia herself.

Nia 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

Overcurrent Shock Unit helps with more fixed damage after drawing a card and is the best for Nia, Fragment of the Empty Void aims for the best turn 1 of the fights and Superconductive Protein helps with that even more where it discounts a single card down to 0 on turn 1. All of these equipment can only be found on Laboratory 0.

List of All Equipment

Alternative Budget Equipment

Weapon	Armor	Accessory
Flashbang	Brainwave-Blocking Helmet	Administrator ID Badge

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. Flashbang to inflict 3 Weaken on random enemies at the start of battle. Brainwave-Blocking Helmet for more fixed shield after drawing cards which is easily achievable by her but can only be found in Laboratory 0 and Administrator ID Badge that gives a single stack of Evade at the start of battle to negate one instance of damage.

Adagio and Eternal Hunger Combo

Shuffle Cards Fast to Activate Decibel

Activate High Cost Cards With G Chord

Unlock Her Potential to Heal More

Adagio and Eternal Hunger Combo

This combo allows Nia to reactivate the effect of Eternal Hunger multiple times to gain AP and 1 card draw by using Adagio to place it on top of the draw pile and drawing it again using another draw effect or another Adagio. Here are the steps to do it:

Make sure that Eternal Hunger and Adagio is in your hand
Use Adagio to place Eternal Hunger on top of your draw pile
Use another Adagio or other cards that draw to get the effect of Eternal Hunger again
Repeat until you run out of Adagio to use

Shuffle Cards Fast to Activate Decibel

The goal of this build is to thin out the deck and activate decibel every other turn. Since decibel scales with extra damage, Nia needs characters that also deals a lot of extra damage such as Hugo and Selena. Nia will be the support of this team with heals built in her kit while Hugo and Selena will try to stack as much Commence the Hunt and Mark to sneak in more extra damage while setting up decibel.

Activate High Cost Cards With G Chord

Another way to use Nia is with G Chord and Adagio to activate high cost cards. The combo is to use Adagio and discard the card you want to activate then play G Chord to play the top card in the draw pile at the cost of only 2 AP so make sure to activate cards you want that are more than 3 AP.

Unlock Her Potential to Heal More

Chaos Zero Nightmare - Nia Potential 3-1
Nia can heal the party using her basic card, Amp Therapy. To further increase the healing, her Potential 3-1 can heal twice as much when an extra attack occurs.
