Rossweisse Skill Kit

Rossweisse's kit includes basic cards, Epiphany upgrades, constructed Light and Dark cards, and an Ego Skill. The following tables summarize the mechanics confirmed in the supplied character reference.

Basic Cards

Card	Type	AP Cost	Effect
Sword Slash	Attack	1	Deals 100% damage
Standing Blade	Skill	1	Provides 100% Shield

These basic cards provide straightforward attack and defensive functions. More advanced deckbuilding revolves around Rossweisse's unique cards and their interactions with Equilux.

Key Epiphany Cards

Card	Base Effect	Build Consideration
Flicker Blade	0 AP, 400% damage; polarizes into Shard and Shard	Core Equilux attack and primary damage-scaling option
Sword Resonance	1 AP, creates 3 Sword Tassels	Helps prepare an enhanced Equilux attack
Radiant Sword Flow	1 AP, 200% damage; discarding a card adds 150% damage	Combines damage with hand management
Blade of the Cycle	1 AP, 200% damage and 4 Brand of the Cycle	Adds damage and Brand of the Cycle utility
Kyrken's Apostle	0 AP, draws 2 cards and provides Kyrken's Aegis	Improves card access and supports Rossweisse's damage setup

These are the base effects listed in the reference. Their Epiphany upgrades can change AP costs, damage multipliers, card generation, and additional effects, so the best option depends on the deck's overall plan.

Constructed Cards and Sword Tassel

Card	AP Cost	Effect
Shard	2	Deals 80% damage to a random enemy; can generate Sword Tassels when Rossweisse's card is activated
Shard	2	Deals 80% damage to a random enemy; can generate Sword Tassels when another Combatant's cards are activated
Sword Tassel	0	Each stack adds 80% base damage to an Equilux card when coalesced, lasting 1 turn

Sword Tassels are central to Rossweisse's damage setup. Generating them before using an Equilux card lets you increase the attack's base damage rather than relying on the attack multiplier alone.

Ego Skill

Ego Skill	EP Cost	Effect
Flickering White Night	6	Deals 1200% damage. When the next Equilux card activates, inflicts fixed damage equal to 30% of the damage dealt to the target

Flickering White Night offers a substantial damage effect followed by additional fixed damage when the next Equilux card activates. It is worth considering how this sequence fits into your planned burst turn.

Rossweisse Upgrade Priority

Rossweisse's development involves several separate systems: card Epiphanies, Potential upgrades, and Manifest Ego. They serve different purposes, so it helps to distinguish improving her regular card rotation from investing in longer-term character progression.

Recommended Upgrade Order

Priority	Upgrade Focus	Why It Matters
1	Learn the Flicker Blade and Sword Tassel interaction	Establishes her main damage setup
2	Develop Sword Resonance and key card Epiphanies	Improves Sword Tassel generation and card interactions
3	Maintain card access through Kyrken's Apostle	Helps access the cards needed for the planned turn
4	Choose Radiant Sword Flow and Blade of the Cycle upgrades to fit the deck	Supports damage, card management, and resource generation
5	Invest in relevant Potential upgrades	Improves card effects and selected combat stats
6	Consider further Manifest Ego stages	Adds damage, card effects, and scaling based on the selected stage

This is a practical progression framework rather than a claim that every account should follow a fixed upgrade order. Your current cards, available materials, and team support will affect which upgrade gives the greatest immediate benefit.

Rossweisse Potential Upgrade Guide

Potential upgrades improve card categories and selected combat stats. Some upgrades also have Attack thresholds that influence their value.

Potential Effects and Materials

Potential	Upgrade Effect	Required Materials
1	Obtain a random Rare Card with an activated Epiphany when entering Chaos	8 Common Growth Stones of Justice, 10,000 Units
2	Basic Card damage, Shield Gain, and Heal Amounts +2%	4 Common Growth Stones of Justice, 3,000 Units
3	Common Card damage, Shield Gain, and Heal Amounts +2%	5 Great Growth Stones of Justice, 16,000 Units
3-1	Reduce Sword Slash cost by 1	16 Great Growth Stones of Justice, 24,000 Units
4	Unique Card damage, Shield Gain, and Heal Amounts +2%	8 Great Growth Stones of Justice, 20,000 Units
5	Critical Chance +2%	16 Premium Growth Stones of Justice, 28,000 Units
5-1	Increase Sword Slash damage; gain an additional modifier when Attack reaches 500	16 Premium Growth Stones of Justice, 2 Shards of Condemnation, 60,000 Units
6	Critical Damage +2.4%	120 Premium Growth Stones of Justice, 42,000 Units
7	Improve Justice damage when Attack reaches 600, with further scaling at higher Attack	36 Premium Growth Stones of Justice, 2 Shards of Condemnation, 80,000 Units

Which Potential Upgrades Should You Prioritize?

Potential 1 provides a Rare Card with an activated Epiphany when Rossweisse enters Chaos, while the following upgrades improve specific card categories and combat stats.

The later Critical Chance, Critical Damage, and Justice damage upgrades are relevant to damage-focused progression. Potential 7 is especially tied to Attack thresholds: Rossweisse gains a Justice damage bonus at 600 Attack, with additional scaling for every 20 Attack above that threshold, up to the listed maximum.

Check your current Attack before investing specifically to reach these thresholds. The supplied data does not establish a universal optimal Potential path for every deck, so prioritize upgrades that match your current build and available materials.

Rossweisse Manifest Ego Guide

Manifest Ego adds new effects at each stage. Every stage requires one Memory Code - Rossweisse and the Ego Manifestation from the previous stage.

Manifest Ego Effects

Stage	Name	Main Effect
1	Sleeping Memory	Adds 1 AP to Kyrken's Apostle and improves attack damage through Kyrken's Aegis
2	Awakening Memory	Increases final damage by 20% at battle start and grants 4 Blade Afterimage
3	Vivid Memory	Adds 400% damage to Flickering White Night and increases its follow-up fixed-damage ratio from 30% to 60%
4	Inner Memory	Grants 1 Precious Name at battle start and when Rossweisse's Light or Dark card effects activate
5	Complete Memory	Increases Potential levels for Basic, Common, and Signature Cards by 3
6	Liberated Memory	Improves attack damage through Blade Poised Against the Cycle and changes hand-capacity interactions for Equilux, Light, and Dark cards

Manifest Ego Investment Priorities

Sleeping Memory improves Kyrken's Apostle and the damage effects linked to Kyrken's Aegis. It is particularly relevant if your rotation makes regular use of the card.

Awakening Memory provides an immediate final-damage increase and introduces Blade Afterimage. When Rossweisse's Light or Dark cards activate, Blade Afterimage can deal damage, generate a Sword Tassel, and consume a stack, up to the specified limit.

Vivid Memory strengthens Flickering White Night and its follow-up fixed damage. Inner Memory offers another damage-scaling layer through Precious Name stacks.

The later stages provide additional card and damage improvements. They require progressively greater commitment, so consider how frequently your deck activates Rossweisse's Light and Dark cards before choosing a high-investment target.

Rossweisse Best Cards and Epiphany Choices

The right Epiphany depends on the role each card plays in your deck. The options below summarize the confirmed differences without assuming one version is universally best.

Card	Relevant Epiphany Effects	When to Consider It
Flicker Blade	Higher damage, shielding, different generated-card effects, or X-cost scaling	When you want to strengthen your main Equilux attack
Sword Resonance	Draw a card, activate a random or all Light and Dark cards, or affect the next Equilux card	When improving card access or Sword Tassel setup
Radiant Sword Flow	Higher discard scaling, cost reduction, or conditional damage bonuses	When the deck can benefit from discarding or manipulating card costs
Blade of the Cycle	Sword Tassel generation, card draw, cost reduction, or effects based on Justice cards in hand	When supporting damage or improving card flow
Kyrken's Apostle	Draws 2 cards and provides Kyrken's Aegis; Manifest Ego can add AP and damage bonuses	When card access and its associated damage effects support your rotation

Flicker Blade Epiphany Details

Epiphany	AP Cost	Listed Effect
I	0	600% damage; polarizes into Amped Light and Dark cards
II	0	600% damage; polarizes into Cycle Light and Dark cards
III	0	400% damage and a Shield equal to 20% of damage dealt; polarizes into Aegis cards
IV	0	600% damage; polarizes into Blink Light and Dark cards
V	X	400% damage, plus 120% base damage for each X; polarizes into Unbound cards

The different versions produce different follow-up card effects. Choose based on the entire deck and its intended rotation, rather than comparing only the initial attack multipliers.

Sword Resonance Epiphany Details

Epiphany	AP Cost	Listed Effect
I	1	Creates 3 Sword Tassels and activates the effect of 1 random Light or Dark card
II	1	Creates 3 Sword Tassels and draws 1 card of this unit
III	0	Applies Retrieve to all Light and Dark cards in hand
IV	1	Creates 3 Sword Tassels; applies Pulverize to the next coalesced Equilux card
V	1	Activates the effects of all Light and Dark cards in hand

These upgrades offer different ways to manage card access and prepare Equilux attacks. The best option depends on whether your deck needs a lower-cost setup, additional draw, or more activation effects.

Rossweisse Best Team Compositions

The supplied team recommendation image presents three team-building directions. The images do not provide readable names for every teammate, so the recommendations below focus on their stated synergy roles rather than guessing character identities.

1. AP and Draw Support + Increased Justice Damage

Team focus: Action Point support, card draw, and Justice damage amplification.

This composition aims to help Rossweisse access the cards she needs and execute her damage setup more consistently. AP and draw support can make it easier to prepare Equilux attacks and use the resulting Light and Dark cards.

Choose this direction if your current deck frequently struggles to assemble its key cards or complete its planned turn. The priority is to make her damage sequence more reliable while preserving the resources required for her main attack.

2. Justice Card Quantity + Damage Support

Team focus: Justice card availability and damage amplification.

This approach emphasizes the number of Justice cards available and the damage benefits associated with Rossweisse's card mechanics. It is particularly relevant when the chosen Epiphanies reward holding Justice cards or improve the effects of Light and Dark cards.

When assembling this team, consider whether the supports help Rossweisse maintain the cards required for her chosen setup. Additional damage support is valuable, but it should not come at the cost of consistently accessing her core cards.

3. Damage Amplification + Harmful Effects + AP and Sustainability

Team focus: Damage buffs, harmful-effect application, AP support, and sustained combat.

This composition combines offensive support with resources for longer encounters. It may be a useful direction when the team needs more than a single burst window or benefits from additional effects that support damage over time.

Evaluate this lineup according to the encounter and the characters you own. The image supports this general synergy direction, but the exact character identities and individual skill effects should be confirmed before assigning a definitive character-by-character ranking.

Rossweisse Pull Recommendation

Rossweisse Build FAQ

What is Rossweisse's main damage card?

Flicker Blade is one of her central attack cards. Its polarization creates Light and Dark cards, linking the attack to Rossweisse's Equilux mechanics and follow-up effects.

Why are Sword Tassels important?

Each Sword Tassel stack adds 80% base damage to an Equilux card when coalesced, for one turn. Generating and using these stacks at the right time is a key part of her damage setup.

Is Sword Resonance worth building around?

Sword Resonance creates three Sword Tassels, and its Epiphany upgrades offer additional card interactions. It is a relevant setup option for decks focused on strengthening Equilux attacks.

What should I prioritize before investing in higher Manifest Ego stages?

Start by understanding your card rotation and building a team that supports AP, card access, or Justice damage. Then compare the specific effects of each Manifest Ego stage with the resources required to obtain it.

Conclusion

Rossweisse's build revolves around Equilux attacks, Sword Tassel generation, and careful card sequencing. Start with Flicker Blade and Sword Resonance, support the rotation with appropriate card-access tools, and select teammates that strengthen her Justice damage or help sustain her setup.
