30-second summary of Biscuit

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

Review & Analysis
Biscuit is an Electric Supporter manufactured by Tetra, ranked B, a familiar cornerstone of mono-Electric teams. Skill 2 is her clutch save: when a Defender ally's HP drops below 50%, Biscuit grants them Invincibility for 5 seconds (up to twice per battle) and heals that ally — invaluable for keeping tanks alive in dangerous moments. Skill 1 triggers at the end of Full Burst, boosting normal attack critical rate and continuous HP recovery for Attacker allies. Her Burst, Walk Training, rebuilds destroyed cover for 2 allies while boosting ATK and healing for other Supporters — full-spectrum support for both offense and defense.
