Zwei — Stats, Skills, Best Teams

Q: Should you pull?

Should you pull?CONSIDER IT — An international community tier list only ranks Zwei B in Story, so she's not a top priority, but she's worth pulling if you need a Burst I Shotgun Buffer/Supporter who generates her own pierce damage and benefits from Tove's SG-specific buffs. If gems are tight and you don't own Tove or don't face much armor-break content, prioritize higher-ranked Burst I Supporters first.

30-second summary of Zwei

Review & Analysis

Zwei belongs to the School Circle squad, with a moderate ATK of 21,307, built around the Pierce mechanic. Skill 1 buffs the team's Pierce Damage +20.13% for 1 round upon entering Full Burst, plus an additional +10.06% for the next 10s. Skill 2 heals Cover for 7.52% after 5 normal attacks, and buffs the team's Critical Rate +18.63% for 5s upon entering Full Burst. Her Burst, 'Overcharge Formula', temporarily changes weapon (1.5s charge time, 50.69% ATK damage, 300% Full Charge Damage, 1-round magazine, with Pierce) and buffs the team's Pierce Damage +15.48% for 10s — a Pierce-focused support, well suited to teams with multiple Pierce-mechanic Attackers.

Skill Investment Priority

Prioritize Skill 1 first since it buffs team Pierce Damage as soon as Full Burst starts — early and reliable, then Burst for its additional Pierce buff and secondary damage, and Skill 2 last since its Cover healing is only a minor support effect.

Skill investment roadmap (Skill 1 / Skill 2 / Burst — general priority): 1/1/1 (functional) → 4/4/4 → 7/4/7 → 10/4/10 (endgame). Why: Skill 1 (pierce damage buff) and Burst (high-damage weapon swap) are her two main damage/utility sources, so prioritize them together; Skill 2 (Cover heal + crit rate) scales steadily but matters less, so it can stop at level 4.

Strengths & Weaknesses

Strengths

Skill 1 self-buffs pierce damage on entering Full Burst, great for fights that demand breaking shields/armor.
Skill 2 both heals Cover HP and raises crit rate on entering Full Burst, contributing to both survivability and damage.
Her Burst fully swaps her weapon for a high-damage pierce charge shot, flexible for a one-shot playstyle.
As a Shotgun user she fully benefits from SG-specific attack-speed buffs like Tove's.

Weaknesses

An international community tier list only ranks her B in Story — not a top pick for regular campaign content.
She has no self-healing beyond Skill 2's Cover heal, so tougher raids need an extra healer.
Her pierce damage buff is wasted against enemies with no shield/armor to pierce.
As a Burst I unit she comes online fast, but her per-turn value doesn't match top-tier CDRs/buffers.
