To maximize Rusalka's damage, players can equip her with Offensive Runes, such as ATK and MAG Runes, to increase her magical attack power. MAG runes can help guarantee that she inflicts the damage reduction debuff with her Kikimora’s Downpour, which triggers if the target's MAG stat is lower than hers. SPD Runes can give Rusalka turn order advantages, while CRIT Rune can increase her chances of landing critical hits.
For defense, HP Runes can boost Rusalka's survivability, CRIT Resist Runes can reduce the likelihood of her taking essential damage, STA Runes can ensure she can use her skills consistently, and Debuff RES Runes can protect her from adverse effects that could hinder her performance. Rusalka's passives will benefit from these runes.

Nina

Rusalka leads the team in well-coordinated strikes, with her magical abilities taking center stage. Cordie's significant damage and speed match Rusalka, whose damage is increased against debuffed opponents. Cordie performs even better when combined with debuffers and CD reduction.
Rusalka's passive revival and Multi-barrier boosts increase team survivability. The team's adaptable strategy is completed by Fia's counterattacking mechanics, Nina's evasion and control, and Merlyn's support for buffing and cleansing. The ability to take advantage of debuffs to deal maximum damage while balancing support and defense for efficient fighting is this team's strongest suit.
Rusalka's skill deals a lot of damage and potentially reduces the offensive power of several enemies with a magical attack. The skill becomes increasingly valuable as one's skill level rises, making it an invaluable weapon in battle.
Multiple magical attacks are unleashed on random enemies by Rusalka's skill. When dealing with debuffed enemies, the damage is enhanced and increases with skill level. This skill benefits from skills that cause debuffs.
