Note: You can also remove Fatal Strike at no save data cost for a better deck cycle.

Nine's best build focuses on defeating enemies in one attack by letting Hew (Extreme) level by itself on turn end while Orlea stacks the multiplicative damage buff then dealing damage ranging from five to six figures to a single enemy after a few turns.

For her Memory Fragments, our setup works best with a 4/2 set using Line of Justice for more critical chance and Executioner's Tool for higher critical damage as you want Nine to critically strike.

Her favored chaos zone is Burning Life to get her best equipment such as Brilliant Eternal Flame for 40% multiplicative damage to 2-cost exhaust cards which is the center of Nine's cards. Fairy King's Crown to get 6% critical chance and Rage Potion for a 40% multiplicative damage to the next attack card after activating 4 attack cards.

Support
Orlea

Nine's best team is Orlea as she can heal while buffing Nine's attacks multiplicatively which is what she needs because of how high her damage multipliers are.

You can pick any characters suggested below as your third party member as long as can they have the right build.

List of All Characters

Suggested Third Party Member

Character	Explanation
Veronica	Veronica can the second Support. She can easily thin her decks with her upgrade cards and provide card draw to the team however she cannot provide damage boosts, healing and can disrupt the damage buffs if she used Firing Preparation.
Beryl	Beryl can be the second Support. She can also do the job of creating spores but at a lesser extent. If you include her with Orlea you will always have more than 5 retain cards and you will draw less every turn.
Nia	Nia can be the second Support. Her main goal in this party is to draw the whole deck and provide AP with Eternal Hunger combo so that Nine and Orlea can setup their cards. The downside with Nia is that you cannot use Forbidden Cards in Season 2 exclusive content and she can consume vulnerable stacks when you have more than 1 Decibel stack.
Rei	Rei can be the second Support. She can exhaust cards to further thin the deck. She can also provide a 20% multiplicative damage boost if she is at Manifest Ego 6.

Nine Best Cards

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Card	Explanation
Hew (Extreme)	AP Cost: 3 Type: Attack Tags: Unique, Initiation, Exhaust, Ephermeral ・300% Defense-Based Damage ・ Incinerate: Create 1 Hew (Extreme) Lv. 1
Fatal Strike	AP Cost: 5 Type: Skill Tags: Unique, Ignition, Retain ・Change Hew in hand to its final level
Counterblade	AP Cost: 0 Type: Upgrade Tags: Unique ・When a card is Exhausted, 1 Honed Edge

Nine's build always revolves around letting Hew (Extreme) exhaust itself on turn end while her party members buff Nine's attacks with multiplicative buffs until the final Hew (Extreme) level.

Her choice of Counterblade will always be the epiphany that grants Honed Edge to her after a card exhausts in this build. This will ensure that her damage will ramp up for every card exhausted even if it is not from Nine's cards.

As for her Fatal Strike, you always want the epiphany that changes the level of the current Hew in hand to the max level so that you can redo the combo again in less turns. You can also remove this card thanks to the save data changes in February 4 Patch so that Nine can easily cycle her cards.

List of All Cards

Essential Team Cards and Epiphanies

Card	Epiphany Effect
Growth Acceleration	AP Cost: 0 ・Heal 100% ・Select 1 Card in hand and trigger Retain effect 2 time(s)
Growing Creature	AP Cost: 1 Tags: Retain ・Create 1 Creation ★ Card ・Retain: Change this card to Softie ★★★ and apply 2 Vulnerable to all enemies
Will of Light	AP Cost: 1 ・Heal 200% ・Activate the Retain effect of all cards in hand
Spore Harvester	AP Cost: 0 Tags: Retain, Exhaust ・Incinerate: Create 2 Contaminated Spore ・ Retain: Create 1 Contaminated Spore

Orlea's cards should be centered on retaining exactly two copies of ★★★ Softie to apply Vulnerable on the enemies and give Nine multiplicative buffs when retained or used. She can also help with card exhausts to give Nine Honed Edge stacks.

As for the Spore Harvester, you only need one copy of it on either Orlea. This ensures that you will always have 5 cards in hand retained at turn start so you will still be able to naturally draw 5 cards every turn.

The best set combination for this build is Line of Justice for more critical chance stat to Nine, Executioner's Tool for more critical damage for her attack cards which is perfect as she wants to have a higher chance of hitting a critical strike to deal massive damage with her Hews.

The main stat and sub stats Nine needs are Order Damage, Critical Chance, Critical Damage and Defense. Her last potential node only needs 300 defense which she can easily achieve it as long as you follow all the main stats recommendations and maxed out her levels and partners.

Refinement: ・Increase Damage Amount of 2-Cost or higher Attack Cards by 25% ・At the start of battle, if owning 18 or less cards, increase Damage Amount of Attack Cards by 30% ・Increase Damage Amount of Exhaust cards by 25%

Nine's best equipment can only be found in Burning Life with Brilliant Eternal Flame giving her 40% multiplicative damage for all of her 2-cost exhaust attack cards. Fairy King's Crown for 6% more critical chance for a higher chance of landing a crit.

Rage Potion is great for her as it will increase the next attack card by 40% multiplicatively after activating 4 cards.

As for your choice of Refinements, the best Nine can get are all about multiplicative damage for exhaust attack cards and 2-cost or higher attack cards. Do take note that these can stack with each other but you can only have one copy for each refinement.

List of All Equipment

Alternative Budget Equipment

Weapon	Armor	Accessory
Command: #108	Titan Combat Suit	Amorphous Cube

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. Command #108 to boost the damage of her first attack in battle by 40% multiplicatively. Titan Combat Suit for a small healing after taking damage once every turn which she can utilize well thanks to her defense stat scaling and Amorphous Cube gives a permanent +25% additive damage to all her attacks.

Hew (Extreme) Full Combo

Card Effects on Hew Does Not Carry Over

Hew (Extreme) Full Combo

Nine's full combo requires you to take turns on buffing her damage with Softie, Spores and Vulnerable until her Hew (Extreme) is at max level to turn it from 1200% damage to a 5 or 6 figure damage at turn 6. Here are the steps to do this combo:

Play Nine's Counterblade then start using Orlea's Will of Light or Growth Acceleration
Do not use Hew (Extreme) until you can 100% defeat the enemy with it. Let it exhaust itself on turn end.
Always end the turn with 2 ★★★ Softies, 1 Spore Harvester and 1 (Hew) Extreme in hand.
(Optional) If you have Rage Potion, use Fighting Spirit to activate Hew (Extreme) 4 times before you begin stacking damage buffs
If Hew (Extreme) will kill the enemy, stop buffing and use it otherwise keep buffing until you can kill it in one hit.

Card Buffs on Hew Does Not Carry Over

All card buffs such as divine epiphanies, card discounts and added effects on it will not carry over when you are leveling up Hew due to how it is done via exhaust and it being created as another card.
