Maximize Nina’s disruptive DPS role by giving her runes like DEX, PM. DEF Break, CRIT, and SPD. This way, she can act first, steal buffs, reflect debuffs, and land crits reliably.

DEX runes in particular are important because Nina’s kit relies heavily on DEX. The higher the DEX, the more successful the debuff transfers, the better the accuracy, and the stronger the synergy with her weapon’s hit chance reduction. These offensive runes let Nina play as a tempo disruptor/DPS hybrid.

As for defensive runes, this selection transforms Nina into a tanky disruptor, where she dodges, resists crits, and cuts excess damage with her passive. These defensive runes let Nina play as a durable anti-control tank.

While Nina might not shine as brightly in PvE, she is an excellent PvP asset when built as a dodge tank. To maximize her effectiveness, position her next to Merlyn and include Dian in your lineup. If Nina holds the highest ATK stat, Dian will grant her a significant EVD boost.

For offensive synergy, add Cordie to provide high damage and essential Defense debuffs. For your final slot, Meria is a top-tier choice because she grants an SPD bonus to the same soul units in her team, which will be Nina, Merlyn, and Cordie. If Meria isn’t available, you can pivot based on your needs. Mimi is great for amplifying Nina and Cordie’s damage output. Freesia can support Nina in doubling down on survivability by stacking an additional EVD buff on top of Dian’s.

In this team, Nina acts as a Buff Stealer/Anti-Sustain, complementing Cordie’s DEF shred, and Yildiz’s buff immunity, while also offering secondary disruption against control-heavy teams. With her weapon, she has a guaranteed buff steal.

Cordie is a high DPS and DEF shred (80% with weapon). She functions as a debuffer and attacker. Fia is a tanky DPS with HP drain and scaling damage from her skill Grim Retribution. She needs sustained and defensive support to maximize her ramping damage. Dian boosts evasion for herself and the ally with the highest ATK. She also provides survivability for the main DPS units. Yildiz is a support unit that grants DEF, P.DEF, and Crit damage cut buffs, especially for Emerald allies, and inflicts buff immunity to the enemies.

Debuffer Team

DPS/Debuffer DPS/Tank Debuffer Debuffer Debuffer
MementoMori - Rusalka IconRusalka MementoMori - Fia IconFia MementoMori - Nina IconNina MementoMori - Stella IconStella MementoMori - Artie IconArtie

This team is built around control, disruption, and survival. Instead of relying on a single damage dealer, this team works by frustrating the enemy, layering defenses, and steadily wearing them down.

Fia soaks up punishment, heals herself through HP Drain, and boosts the max HP of her allies. She makes the whole team bulkier and harder to kill. Rusalka weakens the enemies by reducing their damage output and thrives when enemies are debuffed. She can revive once per battle and give protective barriers to allies. Stella silences enemies, preventing them from using skills. Artie lowers enemy defenses, making them take more damage. Her multi-hit attacks deal huge damage, especially against debuffed or weakened enemies. Nina steals buffs from enemies and uses them herself.

Nina is the disruptor and anti-sustain unit. Without her, enemies might freely buff, debuff, or sustain themselves.

Nina Analysis and How to Play

Nina Analysis and How to Play


Buff Stealer / Anti-Sustain

Nina’s Lost Child’s Tears becomes a guaranteed buff steal with her weapon. This means she can strip shields, regen, or stat buffs from enemies and apply them to herself. With her Unique weapon, damage scales to 480% ATK, so it’s not just utility; it also makes her a strong DPS.

This kind of role works best with burst DPS allies who capitalize on stripped defenses. You can also pair her with CRIT buffers to amplify her stolen buffs.

Control Counter

Nina’s I Hate You!! skill cleanses her own debuff and throws them back at enemies if her DEX is higher. With her unique weapon, Lost Child, the debuff transfer chance is 100%, turning her into a reliable anti-control unit. With her weapon upgrade, she also reduces enemy hit chance by 30% for 4 turns, crippling accuracy.

This kind of role works well with crowd-control allies to stack debuffs while Nina disrupts. It can also work well with tanks who absorb hits.

Tanky Disruptor

Nina’s passives (I Can Still Walk and Shadow Tag) give her permanent evasion at +30%, Damage Reduction at -30%, and excess damage cut up to 65%. This makes her extremely hard to one-shot, even with low DEF. She disrupts enemies by stealing buffs and reflecting debuffs while staying alive. With this role, you have to mind her HP, STA, and EVD to increase her survivability and evasion passive.

This type of role works best when pairing Nina with sustain supports to keep her alive longer. It also works well with disruptors to stack debuffs while she stacks.
