This is Alpha. Come in, Bravo and Charlie. Bolt had infiltrated the wedding ceremony as Espada's bodyguard. The plan was perfect, or would have been, if Nia hadn't taken interest in the glass it held in its right hand. We've gathered evidence that the Terra Heralds are connected to them. Nia was planning on taking just one teensy, tiny sip behind Bolt's back, but quickly fell prisoner to the rich, bittersweet beverage's intoxicating spell. Nia? Wake up. Espada is requesting backup. Yay! I wuv you too, Booooolt! No amount of pleading or cajoling would wake Nia up. Bolt gently laid Nia down in a room by the corner of the wedding hall and weighed its options. Its current frame, a temporary body built for this undercover operation, lacked its usual offensive capabilities. That meant no Plasma Bomber and no Hyper Sword. In that case... Activating Infinity Power Mode. None shall harm Nia while I stand.

Highest team Movement Speed buff (+30%)

Weakness

15 sec buff duration requires management

Undercover Nia's primary value is her Infinity Power Mode buff — a team-wide +30% Movement Speed boost that is the highest of any active skill in the game. While Jiangshi Pooki provides a permanent +20% Movement Speed aura, Nia's +30% surpasses it during the 15 sec window it is active. Her main purpose is in farming teams where speed directly translates to efficiency, though her buff duration requires careful management to maintain consistent uptime.

🤔

Should You Use Undercover Nia?

Yes — in farming teams. Her +30% Movement Speed buff is the highest in the game and maximizes efficiency in Nightmare Shard farming and resource chest farming.

Strengths

Highest team Movement Speed buff in the game — Infinity Power Mode grants all allies +30% Movement Speed for 15 sec, the highest active team Movement Speed boost available. In farming scenarios where covering ground quickly is the priority, this buff directly maximizes the rate at which your team reaches and eliminates enemies.

Weaknesses

Movement Speed buff is not permanent — requires active management — unlike Jiangshi Pooki's permanent +20% aura, Nia's +30% only lasts 15 sec per active skill use. If there are no nearby enemies to trigger her active skill, the buff can lapse and your farming team temporarily loses the speed advantage. Always pair her with Jiangshi Pooki to maintain a baseline Movement Speed bonus between Nia's active windows.
No dedicated game mode presence beyond farming — her combat contribution in structured PvE or PvP is modest. She is a farming specialist first and a combat hero second.

Why Undercover Nia Stands Out

Her +30% Movement Speed active is the highest in the game, making her the go-to farming support for maximizing efficiency in Nightmare Shard and resource farming.

Best Game Modes

  • Farming teams (Nightmare Shard farming, resource chest farming) — her primary purpose. Combined with Jack and Jiangshi Pooki, she contributes to the fastest possible farming formation available, maximizing resource collection efficiency over long sessions.

Build & Optimization

Focus on skill activation speed to maximize buff uptime. Pair with Jiangshi Pooki for constant Movement Speed boost.
