Selena's Ravage build focuses on getting as much Tactical Maneuvers to reset an enemy's tenacity bar. This will let your combatants focused on breaking enemy tenacity bars to re-ravage enemies and re-trigger their ravage effects. This build is particularly effective on The Great Rift content where ravage is a key mechanic and is best paired with Sereniel.

You also want to focus on damage as this setup also lets you use High-Power Scope for multiple coordinated attacks against the enemy.

Selena Best Team

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Main DPS	Support
Sereniel	Cassius

Selena's best team is Sereniel and Cassius. Sereniel can utilize Selena's tenacity restore and her laser spam can be used to let Selena use a lot of coordinated attacks from High-Power Scope.

Alternative Team Members

Character	Explanation
Chizuru	Chizuru can be an alternative teammate for a ravage-focused Selena as Chizuru's bound mechanic can only utilize Ap generation from breaks.
Tressa	Tressa is an alternate combatant that can utilize a lot of 0-cost card. It does require a dedicated healer to re-create Tressa's daggers but it can let you ravage enemies while also utilizing Selena's coordinated attacks from the shadow daggers.

Selena Best Cards

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

Card	Explanation
High-Power Scope	AP Cost: 0 Type: Skill ・When another combatant's Attack Card is used,100% Coordinated Attack for 1 turn
Target Spotted	AP Cost: 1 Type: Upgrade ・On Ravage, 200% Coordinated Attack
Drone Bombing	AP Cost: 1 Type: Skill ・For 1 turn, when performing an Attack Weakness, 100% chance to trigger Coordinated Attack on the target
Tactical Maneuver	AP Cost: 0 Type: Skill Tags: Retain ・If the target is in Ravaged state, recharge Tenacity

Selena's full ravage suport setup requires Tactical Maneuver as your main activator and will also be your duplication priority. Other cards are all focused on attack weakness and coordinated attacks. High-Power Scope is the next mandatory epiphany as this build is paired with Sereniel for multiple attack card usage in a single turn. Target Spotted's upgrade epiphany is the best epiphany choice among all of them as it “exhausts” the card from your deck by being an upgrade card while also providing a lot of damage bonus from ravaging enemies.

Lastly, Drone Bombing is a great epiphany to have as it lets you perform a coordinated attack from a weakness attack which Sereniel can abuse. Using both High-Power Scope and Drone Bombing will let Selena output huge amounts of damage per laser use while refilling their tenacity with Tactical Maneuver lets Sereniel spam her lasers to then re-activate your coordinated attacks again.

Essential Team Cards and Epiphanies

Sereniel Card	Explanation
Homing Laser	AP Cost: 0 Type: Attack ・100% Damage ・ 1 Afterglow ・ On Ravage or at the start of the turn, Move to hand
Plasma Missile	AP Cost: 1 Type: Attack ・120% Damage ・ 2 Instinct Weakness ・ +60% Damage Amount to Homing Laser for 1 turn(s)
Shining Core	AP Cost: 1 Type: Upgrade Tags: Unique, Initiation ・Create 2 Homing Laser L ・ On Ravage, create 2 Homing Laser L
Cobalt Light	AP Cost: 1 Type: Attack ・120% Damage to random enemies ・ Add 1 Hit for each Homing Laser in hand
Cassius Card	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
Shuffle	AP Cost: 1 Type: Skill Tags: Exhaust 2 ・Discard all cards in hand ・Draw as many as the number discarded
Dice Trick	AP Cost: 2 Type: Upgrade ・On Quest completion, create 1 Quest Card(s)

Cassius' important cards will always be the Triple-0 Dice Trick combo to make sure that he can give the party at least 2-3 Morale buffs every turn. However, if he can generate a lot of quest cards, it will interfere with Selena's Homing Lasers from coming back to your hand so make sure to use his quest cards as soon as possible to free up your hand. He can also get Cobalt Light with his Joker if you wish.

For Sereniel. the most important card is duplicated Homing Laser to provide a starting set of card per turn to let you ravage your enemy to create a ravage loop by moving all other created homing laser in the battle to your hand.

Selena Best Partner

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

Partner	Details
Rosaria	Passive Effect: Security Team Requesting Support! - The assigned combatant's Additional Attack damage is increased by 10%. When the assigned combatant uses an Upgrade skill or Skill card, 25% chance to gain Morale for 1 turn. Ego Skill: Financial Support - Draw 1 Enhanced card If there are no Enhance Cards in the Draw Pile, Draw 1

Rosaria can provide Morale per skill card or upgrade card use for 1 turn. This lets Selena also amplify the main DPS' damage output by using her Tactical Manuever while also amping her own damage from the morale buff and Rosaria's extra attack damage buff.

Alternative Budget Partner

Partner	Details
Nakia	Nakia is a great alternative to Selena as Selena performs a ton of coordinated attack which uses her attack stat for bonus damage. Howver, Nakia's backline support is often not utilized and makes Rosaria's team morale buff a better team-focused partner.

Selena Best Memory Fragments

Best Memory Fragment Sets
Black Wing Set		Cursed Corpse Set		Executioner's Tool Set

Selena utilizes the main triple 2-set fragment best. Critical damage and attack damage are both highly valued by Selena and the Cursed Corpse set is a nice 10% bonus if you have an agony source but is easily replaceably by any Memory Fragment with good main stats and substats instead.

List of All Memory Fragments

Stat Priority

Main Stats	Recommended Substats
Ideal: Critical Chance % Desire: Passion Damage % Imagination: Attack %	・Critical Chance % (At least 60%) ・Critical Damage % ・Attack ・Attack %

The main stat and sub stats Selena needs are Instinct Damage, Critical Chance, Critical Damage and Attack. Her last potential node needs at least 60% critical chance so aim for that if you can to get more damage boost to her Homing Lasers.

Selena Best Equipment

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

Weapon	Armor	Accessory
Second Method	Wings of Freedom	Emblem of an Exceptional Entity

Selena's best equipment can only be found in Laboratory 0 with Second Method giving her 35% additive damage for all of her extra attacks in the form of marks. Wings of Freedom for 10% more multiplicative damage each time your team gets hit up to 3 times.

Emblem of an Exceptional Entity is great for her as it has +30% additive damage to all of her attacks making her Homing Missiles much more potent.

List of All Equipment

Alternative Budget Equipment

Weapon	Armor	Accessory
Obsidian Sword	Incomplete Carapace	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. Obsidian Sword to boost the overall damage of all her attacks. Incomplete Carapace for shield if you have 5 or more cards in hand at the end of turn which is easily achievable by her but can only be found in Laboratory 0 and Amorphous Cube gives a permanent +25% damage to all her attacks.

Provide extra DPS through Coordinated Attacks

Selena has no core routine for this build, simply use High-Power Scope and/or Drone Bombing to activate coordinated attack from your teammate's attacks.

Some parts of the guide are from sereniel, like where it says she needs 60% crit chance because her last potential, that´s from sereniel´s kit

Why instinct damage % instead of passion damage %?
