Bay — Stats, Skills, Best Teams

Q: Should you pull?

YES if you need a specialized damage-sharing Defender. Both Skill 1 and 2 activate continuous damage sharing while Bay is alive, plus Burst First Winner cuts the whole team's damage taken by 8.87% for 10s. Her 711171 HP is top-tier in the data, letting her absorb hits well. Worth pulling for teams needing to soften wide AoE pressure in hard Raid/Interception content; if you just need a simple aggro tank, other picks may fit better.

Q: Skill Investment Priority

Skill investment roadmap: 1/1/4 → 4/7/7 → 7/10/10 → 10/10/10. Why: Burst First Winner buffs her Cover and reduces team damage taken, so it comes first; Skill 1's continuous damage sharing plus DEF buff comes second; Skill 2 repeats the damage-sharing and only adds a small Cover heal, so it comes last.

Review & Analysis

Bay (Squad Rewind) is a Defender specialized in sharing damage and buffing DEF for the team, with top-tier HP (HP 711171 · ATK 17059 · DEF 4900). Her Burst, First Winner, boosts her own Cover Max HP +18% for 20s and reduces the whole team's damage taken by 8.87% for 10s. Skill 1, You Can Do It, on using Burst (while alive) makes the team continuously share incoming damage proportionally, plus grants Bay a continuous +10.13% DEF buff. Skill 2, Cheer Up Together, repeats the damage-sharing mechanic, and on Full Burst ending heals her Cover 2.88% Max HP per second for 5s. A solid tank pick for teams needing to soften wide AoE pressure.
