30-second summary of Rosanna

Rosanna is a Electric Nikke in the Attacker class, manufactured by Tetra. Stats and skill text below come straight from the game's data.

Review & Analysis
Rosanna is an Electric Attacker wielding an MG with Burst I, built around a Concealment (untargetable) playstyle that leads into a burst of damage. Skill 2 Capo dei Capi triggers Concealment automatically on battle entry, and stacks ATK plus fills Burst Gauge whenever an ally falls. Skill 1 On the Lam triggers Concealment again after 120 normal attacks and boosts Critical Damage, while also dispelling enemy buffs. Her Burst Vendetta deals heavy damage to 2 Attacker-class enemies, dealing an equal bonus hit if she's currently in Concealment — turning her stealth tool into a finishing blow.
