2B — Stats, Skills, Best Teams

Q: Should you pull?

YES if you need a durable AoE Attacker. Her Burst, Series of Attacks, lands 2439.36% ATK AoE plus 792% ATK on the highest-HP target in one go — very effective on multi-enemy stages. Combined with top-tier HP in the data and Skill 1 stacking Max HP with every Burst, 2B both clears waves and sustains herself. Worth pulling if you need reliable AoE for Campaign/Tower; skip if you only need maximum single-target damage.

Q: Skill Investment Priority

Skill investment roadmap (Skill 1/Skill 2/Burst): 1/1/4 → 4/7/7 → 7/10/10 → 10/10/10. Why: Burst is her main AoE damage source (2439.36% + 792% ATK), so raise it first; Skill 2 Cluster Bomb contributes steady AoE damage so it comes second; Skill 1 Survival only adds bulk and barely affects damage, so it comes last.

Review & Analysis

2B belongs to Squad YoRHa with top-tier HP in the dataset (HP 711171 · ATK 17059 · DEF 5015), playing as a durable AoE Attacker. Her Burst, Series of Attacks, hits all enemies for 2439.36% ATK plus an extra 792% ATK on the highest-HP target — excellent for clearing multiple enemies at once. Skill 2, Cluster Bomb, triggers after 300 shots fired for 167.45% ATK AoE damage and grants herself ATK scaling off her own Max HP. Skill 1, Survival, stacks Max HP buffs on herself the more she uses Burst, making her tankier the longer the fight runs. Good fit for wide multi-target stages like Tower or crowded Campaign fights.

Strengths & Weaknesses

Strengths

Top-tier HP in the dataset (711171), holds up well in long fights.
Very strong AoE Burst (2439.36% + 792% ATK), efficient at clearing multiple targets.
The more Burst is used, the more Skill 1 stacks Max HP, self-compensating for durability.

Weaknesses

ATK is only mid-tier (17059), not the top pick for single-target damage.
Skill 2 needs 300 accumulated shots to trigger, slow to come online.
