Chaos Zero Nightmare (CZN)SelenaBuild and Guide

• Mark: Mark is a stackable debuff that Selena can apply through a wide variety of her cards, forming the core of her kit. When an enemy is marked and an Attack card is used, Selena will fire an additional attack toward the marked target/s, dealing 100% ATK damage. To take advantage of this, Mark generation needs to be combined with high-frequency attacks to achieve the best results.
• Break: The other mechanic core to Selena’s identity is break and tenacity damage. Many of Selena’s abilities cause her attacks and additional attacks to either inflict additional tenacity damage or increase the tenacity damage dealt by a %. Building on this, Selena also has abilities that provide additional benefit each time an enemy is broken, further incentivizing a high tenacity damage break playstyle.
• Response: Triggers listed “Response” effect when drawn naturally or via card effect.
• Break: A debuff that causes the enemy to be treated as though they are Passion weak for all combatant attacks while it remains active. It is duration-based, not hit-count-based.

5

Final Shot

Ego Skill

300% Damage.
3 Mark.

Show Effects

Final Shot

Costs 5 EP, deals a strong amount of single-target damage, and most importantly, immediately applies 3 Mark. Should be used as early as possible on the primary target to prevent mark waste and to allow Selena to begin her Mark fuelled rapid fire assault.

1

Engagement Fire

Attack

100% Damage.

Engagement Fire

Selena’s basic attack is normal, but gains the ability to deal Piercing Damage and a significant damage enhancement from Potentials. In addition to this, Engagement Fire is also a perfectly suitable and accessible tool for triggering marks.

1

Emergency Shielding

Skill

100% Shield.

Show Effects

Emergency Shielding

Selena’s basic shield is completely standard and doesn't have any extra synergy with her kit.

1

High-Power Scope

Skill

2 Mark.

Show Effects

High-Power Scope

One of Selena’s core Mark sources, which costs 1AP and applies 2 Mark to a target on use. Not overwhelmingly powerful at a baseline, but can be significantly improved via Epiphanies.

1

Target Spotted

Attack

150% Damage.
Attunement: 1 Mark to random enemies.

Show Effects

Target Spotted

Selena’s other primary Mark generator, which functions very differently. Generates 1 Mark on 1 random enemy via its Response effect when drawn. Outside of this costs 1AP to use and deals a solid amount of damage, but nothing else. A solid card, as it doesn’t HAVE to be used in order to gain value while still being there as a hit to activate marks if Selena needs

1

Drone Bombing

Attack

120% Damage to all enemies, 1 Passion Weakness.​

Show Effects

Drone Bombing

Deals AoE damage to all targets and applies Passion Weakness for 1 turn, guaranteeing this turn's hits will deal tenacity and direct damage as though the enemy were weak to Passion. Synergizes well with Selena’s goal of breaking enemies while also adding a dash of AoE to her kit.

1

Tactical Maneuver

Skill

150% Shield.
2 Tenacity Damage.

Show Effects

Tactical Maneuver

Grants a larger-than-average shield and deals 2 Tenacity damage to a target of your choice immediately. Great for locking in breaks on enemies while also offering some defensive benefits.

0

Sniper's Domain

Upgrade

[Unique]

+40% Mark Damage

Show Effects

Sniper's Domain

Selena’s only upgrade baseline cost 0AP, is unique, and boosts Mark damage by +40%. A simple, strong damage multiplier for one of the largest portions of Selena’s damage.

Selena’s Signature Potentials offer significant damage boosts as well as some additional functionality, making them a high priority to unlock.

• 3-1: Causes Engagement Fire to deal Piercing Damage, which ignores enemy shields.
• 5-1: Increases Engagement Fire’s damage multiplier by +5% with an additional +5% bonus granted if Bonus Additional Damage exceeds 15%.
• 7: Increases Passion DMG% by +4% passively, with a further +4% increase unlocked if Bonus Additional Damage exceeds 30%..

Standard Playstyle

Selena is a mix of two playstyles: Additional Attacks via Mark and Break through her tenacity damage and Passion Weakness. You may choose to specialize in one more heavily than the other, but regardless of which you choose, Selena’s game plan remains the same. Establish buffs and marks, then trigger as many additional attacks as possible either through her own attacks or her teammates to unleash a barrage of high damage gunfire.

Note

For every Epiphany, we're colored their name based on how useful we think it is compared to the other variants. Here's the key to the colors:

• Epiphany Name - the best variant,
• Epiphany Name - a good variant,
• Epiphany Name - a niche variant.

Recommended Loadout

1

Executioner's Tool [2-PC]

[2-PC]: +25% Critical Damage.

Black Wing [2-PC]

[2-PC]: +12% Attack.

Flex

The combo of Executioner’s and Black Wing is, in most cases, Selena’s best set combo, assuming you can get some value from either2P

Cursed Corpse [2-PC]

if the enemy has Agony on them or 2P

Seth's Scarab [2-PC]

if you’re using Selena’s basics to deal damage.

2

Spark of Passion [4-PC]

[4-PC]: When Upgrade Cards are used, increase Damage Amount of the next 5 Passion Cards used by 20%.

Executioner's Tool [2-PC]

[2-PC]: +25% Critical Damage.

Selena has a lot of base damage boosts for her Marks but no easy access to multiplicative DMG% boosts, making 4P Spark of Passion a solid choice if you can’t manage to get Agony on the enemy consistently or find much value in Seth’s Scarab. Keep in mind that after five attacks, the boost from this set will be gone, as Selena only has one upgrade to use. Combine it with 2P Executioner’s.

2-PC Bonuses

• 

  Executioner's Tool [2-PC]

  - The 25% unconditional Crit DMG from this set makes it Selena’s best option among 2P sets.
• 

  Black Wing [2-PC]

  - A 12% unconditional ATK% increase benefits all of Selena’s abilities and is a stat she can’t get anywhere else apart from gear, making it a high priority.
• 

  Cursed Corpse [2-PC]

  - Grants +10% Multiplicative DMG% to all of Selena’s abilities as long as there is Agony on the target. Selena doesn’t usually run with teammates that apply Agony and usually doesn’t do so herself, but if you can manage to fit it in, this set is very powerful for her..
• 

  Seth's Scarab [2-PC]

  - Some damage-focused Selena builds keep in basics even in endgame, making Seth’s Scarab an appealing choice in Zero System while also providing benefits in endgame.

4-PC Bonuses

• 

  Spark of Passion [4-PC]

  - Grants a buff after using an upgrade that increases all Passion ability damage by +15% multiplicatively for the next five attacks. This is a good stat for Selena, and she can activate it easily thanks to Sniper’s Domain, which at E1 has Initiation. This buff affects Mark and Coordinated attacks, but neither of them consumes its charges. With that said, eventually it will still run out if you’re attacking with Selena. A solid choice, but it usually doesn’t compete with 2/2/2 set-ups.

Comments - Weapons

1. 

   Second Method
   - Grants +30% Additive Extra Attack damage to Selena’s Marks and coordinated attacks. In a lot of Selena builds, these two damage types make up a large amount of her damage, making this one of her top shop weapon equipment.
2. 

   Obsidian Sword
   - Grants +8% Multiplicate damage to all of Selena’s damaging abilities, including Marks and coordinated attacks. Not as strong as the Second Method, but better than you might expect, since a lot of +Mark damage, like Sniper’s Domain, is base damage that this stat type multiplies.
3. 

   Bone Cutter
   - Another +30% Additive damage multiplier for Selena, but to all her abilities, but only while they have the Weaken debuff. A good option if you can consistently apply the debuff; otherwise, not usable.

Comments - Armor

1. Flex - When playing Selena more as a Support, this slot is more important, but in damage-focused builds, there aren’t many synergistic options available from the shop. This slot is ideally taken up by an Event/World item, but if you don’t find any, feel free to fill it with any equipment you see fit or a defensive option to boost shielding.

Comments - Trinkets

1. 

   Dimensional Cube
   - Grants Selena +10% additive damage whenever any character discards any card anywhere, with the exception of the end-of-turn discard. When paired with characters like Nia and Cassius, this option can outperform all other Shop damage choices as the damage is added to her normal, mark, and coordinated attack damage. Useless without a discard enabler, though.
2. 

   Amorphous Cube
   - Grants Selena a permanent +25% Additive damage bonus to all her abilities, including Marks and Coordinated Attacks. A solid and consistent damage boost across the board that’s always worth taking if you have nothing else.
3. 

   Quantum Collector
   - A higher potential alternative, but which requires specific play. Grants Selena a stacking +20% multiplicative damage bonus to all her damage for 1-turn per upgrade played this turn. Selena only has one upgrade herself, so this accessory requires other teammates to help it shine, and even then has a short shelf life.

Important!

CZN is a game of randomness; sometimes you’ll be offered generic or Divine epiphanies that are stronger than a character's standard five options. In these cases, breaking the listed build can result in an even more powerful save. Adjust as you see fit!

Card Removal Priority

• Emergency Shielding: If you need your Selena to shield, many incredibly powerful shield-based Epiphanies are available within her kit, making her basic shield underwhelming to keep long-term. Remove it when you can.
• Engagement Fire: When playing Selena as a main damage dealer, her basics are worth keeping, but when playing her in a more supportive role, they’re optional. If you want minimal or no offensive capabilities for Selena in exchange for a very thin deck, it may be worth removing one or both.

Card Dupe Priority

There is no definitive choice when it comes to choosing which Sub DPS / Support Selena card to dupe in the deck.

• High Power Scope II can be duplicated for 2 Marks on every target a turn instead of one, boosting damage.
• Drone Bombing III can be duped for another huge 0-cost AoE payoff ability, assuming you have enough Passion cards to stack them.
• Target Spotted IV cycles itself for free when drawn, so adding another copy of it to your deck just gives you more shielding options in hand with no downside.
• Tactical Maneuver I adds another big shield and more potential tenacity damage that can potentially be converted into AP.

Epiphany Alternatives

Many of Selena’s Epiphanies completely change the original card's meaning, using an alternative one can change how your build works as well. If you want something else for Selena, check out other variants to see which suits your style best.

Veronica

• Has incredibly AP-efficient and numerous card draws, allowing Selena to churn through her deck faster.
• Deals very solid sub DPS without requiring too much AP, leaving it for Selena or her teammate.
• Has many upgrades, which thin the deck considerably, boosting access to Selena’s own cards.

Mika

• Has tremendous healing enough to keep the team alive even in the endgame herself
• Has retain and upgrade card/s, which, after set-up, and if held, make cycling the remainder of her deck very quick
• Absurd AP generation allows Selena and her other teammates to spam cards without worry

Mei Lin

• Can take advantage of Mei Lin’s Passion Weakness while also gaining benefit from her attack spam, which fuels some of Selena’s best cards.
• Selena’s great AP efficiency leaves more resources for Mei Lin and her teammates' comboing.
• Selena prefers high hit frequency allies to trigger all marks applied, which Mei Lin provides.
• Offers fantastic Tenacity Damage, which complements Selena’s break-focused effects and playstyle nicely.

Important!

If you’re losing runs when playing a damage-focused composition either to sanity or dying, consider using a team with more defensive characters - so including both a shielder and healer. This is especially important in the Zero System mode.
