Nia's best build for the Season 2 content revolves around discard synergy while providing draws and buffs to the party. She focuses more on discarding therefore she is best paired with characters that has benefits when their card is discarded.

Her best set is still the standard 2/2/2 set for supports which are Healer's Journey for extra HP, Seth's Scarab for more value from her Amp Therapy in chaos runs, and Tetra's Authority set. Alternatively, you can also gear her with the 4 piece Glory's Reign set as other combatants can use their exhaust cards to activate its effect.

Her favored chaos zone is Burning Life to get her best equipment such as Vine Lord's Mask for more fixed shield after drawing exhaust cards. Combat Drum for a 20% multiplicative damage buff to the next attack from allies after exhaust 5 skill cards and Tentacles of Chaos for an 8% attack buff to allies but can only be obtained from Senectus.

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 while 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.

Nia Best Cards

Memory Fragment				Equipment				Playstyle

Card	Epiphany Effect
Mute Accent	AP Cost: 1 ・Discard all highest-cost cards ・The owner of those cards deals 100% Extra Attack on a random enemy
Nia's Curiosity	AP Cost: 1 ・Reveal 3 random cards from the Draw Pile ・Choose one to Draw ・Discard the rest
Soul Rip	AP Cost: 2 ・When discarding a card, 1 Decibel, 1 Elasticity
Adagio	AP Cost: 0 ・Discard 1 ・Draw 2 card(s) of the owner of that card
Spore Harvester	AP Cost: 0 Tags: Retain, Exhaust ・Incinerate: Create 2 Contaminated Spore ・ Retain: Create 1 Contaminated Spore

Due to the restrictions of Season 2, Nia's best cards does not revolve around Eternal Hunger anymore. Her ability is best used for discard synergy therefore she must focus on as much discard as possible while retaining the ability to provide draw for the party.

First, Mute Accent's epiphany must be the version that discards all highest-cost cards so that you can combo this with Dirge Bullets which has the same cost of 1 AP and therefore will be discarded as long as there is no 2 AP or more cards in your hand.

Soul Rip should have the epiphany that turns it into an upgrade card to thin your deck and provide a decibel and elasticity stack after discarding a card. Adagio, on the other hand, must now have the epiphany that only discards 1 but draws 2 card based on whose card was discarded.

G Chord does not really have a place in this build therefore it is best removed from the deck.

List of All Cards

Essential Team Cards and Epiphanies

Card	Epiphany Effect
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
Last-Ditch Assault	AP Cost: 1 Tags: Retain, Exhaust ・150% Damage (+0%) ・Discard all Dirge Bullets and +50% Damage for that amount
Resonating Darkness	AP Cost: 1 Tags: Unique ・+60% Damage of cards with cost 1
Resonating Darkness	AP Cost: 0 ・For 1 turn, +80% Damage to cards with cost 1
Snack Time	AP Cost: 0 Tags: Retain, Exhaust ・Heal 200% ・Draw 2
Dark Condensation	AP Cost: 1 ・For 1 turn, +50% Damage to Void attack cards

Renoa's cards must have a sufficient way to generate and discard Dirge Bullet. Flower of Devoured Fate must be the epiphany that discards up to 3 cards to generate 3 Dirge Bullets while Ballad of Pitch Black must be the epiphany that gives your Dirge Bullets +100% additive buff to the extra attack damage.

As for Rei, Season 2 enables you to obtain one unique and non-unique epiphany for each card therefore you can get one Resonating Darkness that boosts 1 AP cards by 60% additively and another Resonating Darkness that boost the same 1 AP cards for 80% but only for 1 turn.

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. After the Season 2 Balance, Nyx now gives a boost to defense, health and healing amount to Nia.

Nia Best Memory Fragments

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Your standard 2/2/2 set for non-DPS combatants. Healer's Journey and Tetra's Authority provides stats the team wants for extra sustain and durability. Seth's Scarab lets you use Nia much more easily on content that has her basic cards such as chaos zones for easier deck building.

The new 4 piece Glory's Reign set can be activated by other combatants too so if your other combatants benefits from a different set piece, Nia can also remove Healer's Journey Set and Seth's Scarab set to carry the 4 piece set for herself to give the team some team-wide bonuses.

List of All Memory Fragments

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

Weapon	Armor	Accessory
Tentacles of Chaos	Vine Lord's Mask	Combat Drum
Refinement: ・At the start of the turn, if an Exhaust card is in Draw Pile, have a 30% chance to Draw 1 Exhaust card(s). ・At the start of battle, Draw 1 Exhaust card(s) of this unit ・Increase Shield Gain Amount by 15%, and increase Heal Amount by 15%

Nia's best equipment can only be found in Burning Life with Vine Lord's Mask giving her fixed shield after drawing an exhaust card up to 2 times. Combat Drum for a 20% multiplicative damage boost to the parties next attack after exhausting 5 skill cards.

As for her weapon slot, you want to have Tentacles of Chaos which provides an 8% attack boost for her allies but can only be obtained from Senectus. However, due to how limited the selection of equipment Nia has, you can use any other chaos zones as long as you get Tentacles of Chaos.

As for her refinements, the best Nia can get revolves around drawing exhaust cards as a guarantee but only at the start of battle or a 30% chance each turn to draw 1 exhaust which in this build is most likely a Dirge Bullet.

List of All Equipment

Alternative Budget Equipment

Weapon	Armor	Accessory
Flashbang	Titan Combat Suit	Grey Orb

If you aren't able to get the best, you can settle for these equipment that can be found in any chaos zones inside shops. Flashbang to inflict 3 Weaken on random enemies at the start of battle. Titan Combat Suit for healing after getting hit once every turn and Grey Orb that gives 3 damage reduction at the start of battle but this equipment can only be obtained after reaching 30 exploration level on The Foretold Ruin.

Mute Accent Dirge Bullet Combo

Adagio and Eternal Hunger Combo

Shuffle Cards Fast to Activate Decibel

Activate High Cost Cards With G Chord

Mute Accent Dirge Bullet Combo

One consistent combo you can do with Nia that enhances Renoa's damage is to use Mute Accent to discard up to 9 Dirge Bullets resulting to 9 extra attacks from Mute Accent and another 9 extra attacks from the Dirge Bullets after getting discarded. Here are the steps to execute this combo:

Create Dirge Bullets using Echo of Sorrow or Flower of Devoured Fate.
Keep creating Dirge Bullets until you have either Last-Ditch Assault or Mute Accent alongside a few Dirge Bullets.
(Optional) Use Ballad of Pitch Black to increase the damage of your Dirge Bullets.
Use either Last-Ditch Assault or Mute Accent to discard all your Dirge Bullets.
Use Renoa's Ego Skill to return all your Dirge Bullets back to your hand.
End your turn or (Optional) Use your Last-Ditch Assault or Mute Accent, whatever is left, to discard your Dirge Bullets again.

Adagio and Eternal Hunger Combo

This combo can only be done outside of Season 2 content and 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.
