T0 Partners: The Meta Essentials, Versatile & Core Engines

1. Nyx (Controller)

• Ability Analysis: Universally acknowledged as the premier "all-rounder" choice. Her passive provides a team-wide damage boost after a Combatant draws a card, offering both offensive and defensive value. Her EGO skill (4-cost) is incredibly powerful: Discard your entire hand, then draw the same number of cards + 1. This can single-handedly turn the tide of a battle ruined by a bad hand.
• Recommended For: Almost all mainstream Controllers like Mika, Cassius. As Controllers are the most commonly deployed role, Nyx's versatility is unmatched and is the safest, most recommended pick for most players.

Nyx (Controller)

2. Scarlet (Duelist)

• Ability Analysis: The ultimate specialized support for Duelists. Her passive significantly boosts the equipped Combatant's damage, perfectly fitting into team cycles that use low-cost support cards to set up for the main DPS's burst turn.
• Recommended For: The ultimate partner for Mei Lin. She completely outclasses the Battle Pass Duelist partner, Priscilla.

Scarlet (Duelist)

3. Serithea (Hunter)

• Ability Analysis: The dedicated engine for critical-hit Hunters. Her passive provides a substantial crit rate, and each crit hit stacks crit damage, offering massive returns in prolonged battles. Her EGO skill also applies "Vulnerable" to enemies, further increasing the entire team's damage output.
• Recommended For: Hunters that rely on critical hits, such as Luke and Renoa. If your main DPS is a Hunter, she is one of the top-tier investments.

Serithea (Hunter)

4. Marianne (Duelist)

• Ability Analysis: An expert at amplifying "Weak Point Damage." She causes all of the equipped Combatant's cards to apply Weak Point Damage and provides extra damage against "Weakened" enemies. Her EGO skill is a powerful single-target nuke.
• Recommended For: Duelists who utilize basic attack cards or can frequently apply Weaken, such as Rin and Mei Lin.

Marianne (Duelist)

5. Anteia (Psionic)

• Ability Analysis: A core amplifier for Psionic characters. Her passive increases HP, overall damage, and attack card damage. Her EGO skill deals damage to all enemies and applies one stack of "Vulnerable" to each, combining clear power with strong support utility.
• Recommended For: Psionic characters who can generate cards quickly, such as Tressa.

Anteia (Psionic)

 

T1 Partners: Specialized Experts, Pillars of Specific Comps

1. Solia (Ranger)

• Ability Analysis: Boosts the equipped Combatant's "Extra Damage" and Attack Card power for 1 turn after drawing a card via an ability. Her EGO skill deals high single-target damage and applies a "Mark."
• Recommended For: Rangers who often act as sub-DPS, like Selena and Veronica. As Rangers are typically not the primary damage dealers, their partner's priority is slightly lower than that of a main DPS.

Solia (Ranger)

2. Asteria (Duelist)

• Ability Analysis: A highly specialized partner. She greatly enhances the damage of 2-cost cards and deals extra damage to shielded enemies. Her EGO skill is low-cost but requires discarding your hand to achieve maximum burst damage.
• Recommended For: She is almost the exclusive partner for Haru, perfectly synergizing with her high-cost "Anchor Shot" burst playstyle. Her effectiveness drops significantly on other Duelists.

Asteria (Duelist)

3. Kiara (Hunter)

• Ability Analysis: Powerful but conditional. Her passive requires you to discard a card and have a sufficient number of cards in the graveyard to grant a large attack card damage boost. Her EGO skill's damage scales with the number of cards in the graveyard.
• Recommended For: Currently, the only character who can fully utilize her potential is Renoa.

Kiara (Hunter)

4. Bria (Psionic)

• Ability Analysis: Her passive requires generating a certain number of cards to trigger a high damage bonus, making her excel in long, challenging fights like Chaos stages.
• Recommended For: Psionic characters who can generate cards rapidly, such as Tressa.

Bria (Psionic)

 

High-Value Low-Rarity Partners — The Budget Powerhouses

Don't underestimate low-rarity partners. When fully maxed out, their passive stat multipliers are significant, and they are extremely easy to obtain.

Douglas (3-star Duelist)	At max duplication, provides 16% ATK and a first-turn 16% independent damage multiplier. Simple and effective, can be used by any Duelist. An excellent budget option for Mei Lin before you get their best-in-slot partners.
Lillian (4-star Duelist)	Her effect is similar to Marianne and is one of the best Duelist partners right under Scarlet. Obtainable through summons and easy to get high duplicates.
Yvonne (3-star Controller)	Her passive provides DEF (increasing healing and shield strength) and heals the party at the end of a turn where no attack cards were used. The condition is easy to meet, offering excellent sustain. A great choice for long battles (like the Zero System) and can even outperform some 4-star Controllers.
Baihe (3-star Hunter)	Provides ATK and a permanent damage boost after the first shuffle. Her EGO skill, "3-cost, Draw 2," is an excellent cycling tool that any class can use to smooth out their hand.
