Biscuit — Stats, Skills, Best Teams

Q: Should you pull?

Should you pull?PULL — Biscuit is a rare all-in-one Supporter combining crit buffs, healing, cover rebuilding, and a squad-saving invincibility into one kit. Worth investing in for both new and veteran players, especially valuable in long raid fights.

Q: Skill Investment Priority

General guideline: 4/4/4 → 7/4/7 → 10/7/10. Why: Skill 1 (crit + Attacker healing) and Burst (cover rebuild + buff + heal) are her two core effects and should come first; Skill 2 is capped at twice per battle, so further investment there has lower value.

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.

Skill Investment Priority

Prioritize Skill 2 (Invincibility save for Defenders, a life-or-death tool) → Burst (rebuilds cover + Supporter buff) → Skill 1 (critical rate/heal buff for Attackers at end of Full Burst).

General guideline: 4/4/4 → 7/4/7 → 10/7/10. Why: Skill 1 (crit + Attacker healing) and Burst (cover rebuild + buff + heal) are her two core effects and should come first; Skill 2 is capped at twice per battle, so further investment there has lower value.

Strengths & Weaknesses

Strengths

Her Burst rebuilds cover (93.6% HP), buffs Supporter ATK by 43.08%, and heals — three effects packed into one skill, extremely versatile.
Skill 2 grants a Defender temporary invincibility in a critical moment, a rare squad-saving tool for a standard Supporter.
Skill 1 both boosts crit and continuously heals Attackers, supporting damage and survival at the same time.

Weaknesses

Her Rocket Launcher needs a 1-second Charge Time, unsuited to instant reaction plays.
Skill 1 only triggers at the end of Full Burst, doing nothing for the rest of the fight.
Skill 2 is capped at twice per battle and only applies to a Defender, unable to save a low-HP Attacker or Supporter.
