[Little Big Adventure] Nina Analysis

AoE Damage Scaling

Lost Child’s Thunder

Go Away!!

Nina's skills offer a blend of offensive and defensive utility. Lost Child's Thunder deals strong AoE damage that scales well with her ATK, while also providing a moderate defensive buff to all allies. However, the DEF buff itself is somewhat weak.

Go Away! offers more focused support by dispelling debuffs from allies, but the dispel is random at lower levels and the damage buff chance isn't guaranteed.

Both skills see significant improvements at higher levels, with Lost Child's Thunder gaining potential for further enemy DEF reduction and Go Away! targeting more allies for debuff removal.

ATK Boost and Debuff Cleansing

Nina’s Special High Five

Nina's Special High Five shines as a team support skill, boosting attack (ATK) and cleansing debuffs. The Lv2 upgrade offers a dynamic ATK increase based on a debuff's duration, while Lv3 expands the benefit to more allies.

However, it relies on Nina being debuffed first, offers a limited buff duration, and might not always target the optimal allies. While it doesn't heal, its offensive and cleansing capabilities can be very valuable with strategic positioning and potential synergies with debuff-inflicting skills.

Strong Shield Potential

Sign of a Good Kid

Sign of a Good Kid excels at protecting Nina and her strongest ally with a powerful shield based on Nina's ATK. It activates both at the fight's start and whenever an ally falls, offering both proactive and reactive defense. Higher skill levels enhance this further with Lv2 buffing ATK based on fallen allies and Lv3 doubling the shield's strength.

However, the skill relies on Nina having high ATK for maximum benefit and doesn't offer healing. Additionally, the Lv2 buff hinges on risky ally deaths, and the shield prioritizes the strongest ally, potentially neglecting the most vulnerable one. While offering strong defense and potential offensive boosts, Sign of a Good Kid might be best for specific team strategies that can manage controlled ally falls.

[Little Big Adventure] Nina Best Runes

Prioritize ATK, CRIT and HP Runes

ATK Rune is the best rune to prioritize as they directly boost Nina's damage across all her attack-based skills. CRIT Rune synergize well by increasing the chance of critical hits, which can trigger bonus effects for Lost Child's Thunder and potentially deal more damage with other skills.

PM. DEF Break Rune can be a support if you're facing particularly tough, high-DEF enemies. On the defensive side, HP Runes are a solid choice to improve Nina's survivability. STA Runes offer a slight HP boost too.

[Little Big Adventure] Nina Best Team Comps

Azure Affinity Team

Attacker	Buffer	Attacker	Buffer	Debuffer
Florence	Fenrir	Summer Nina	Sivi	Soltina

Nina and Florence deal high damage, with Nina also providing defensive buffs and shields. Fenrir keeps the team healthy with heals and cooldown reduction, while Sivi boosts damage output and heals herself. Soltina adds utility with debuffs like Sleep and Faint, along with self-preservation through debuff cleanse and multi-barrier. Overall, the team offers a good balance of offense, defense, support, and debuff management.

PvP Team

Buffer	Attacker	Debuffer	Attacker	Buffer
Summer Nina	Rusalka	Eir	Summer Sabrina	Merlyn

Summer Nina shields and buffs allies, while Rusalka debuffs enemies and deals heavy damage, reviving once. Merlyn cleanses, heals, and buffs crit rate/defense, with her allies gaining regeneration. Eir dominates debuffed enemies, lowering their crit resist, potentially sleeping them, and dealing high damage. Summer Sabrina targets high-HP enemies and unleashes a buff-dispelling rampage.
