Should you pull?

CONSIDER IT — Mary: Bay Goddess shines best in an all-Water team and long-form content (Raid, Interception) thanks to her scaling-over-time effects; in short matches (Arena) her value drops since there's no time to build up. Pull if you're building a dedicated Water-element lineup.

Review & Analysis

Mary: Bay Goddess is an SSR Water Supporter, an upgraded incarnation of Mary specialized for the Water mono-element team. Skill 2, Waves Kiss The Feet, triggers on Burst Skill use and stacks a Damage-as-strong-element buff for all Water Code allies — her main damage-amplification tool. Skill 1, Seaside Sunshine, provides HP regeneration over time for the team, growing stronger with repeated Full Burst entries. Burst skill Tranquil Waters boosts ATK for Water Code allies and adds bonus Max HP as a survival buffer for the whole team. Featured in the Water mono-element team and ranked tier B, Mary: Bay Goddess is a strong pick for Water-focused compositions.

Skill Investment Priority

Prioritize Skill 2 Waves Kiss The Feet (elemental damage buff for the whole Water team, her main amplifier) → Burst Tranquil Waters (ATK buff plus HP buffer) → Skill 1 (HP regen over time).

Skill investment roadmap (Skill 1/Skill 2/Burst): 4/4/4 (functional) → 7/4/710/4/10 (endgame). Why: Skill 1 and Skill 2 are both stacking-over-time mechanics, so they matter equally and should be raised alongside Burst (wide-area ATK + Max HP buff); none should be neglected since all three feed her long-fight playstyle.

Strengths & Weaknesses

Strengths

  • Skill 1 heals over time and SCALES UP with each activation (up to 6.86% per second for 5 seconds on the third trigger), so healing value grows strongly in long fights.
  • Skill 2 similarly scales up Water-element damage buffs for the whole Water Code squad with each Burst Skill use.
  • Burst buffs Water-element ATK and Max HP squad-wide.
  • As an SR, fully-charged normal attacks get a 250% multiplier.

Weaknesses

  • Both Skill 1 and Skill 2 need MULTIPLE activations to reach peak value, not strong from the start of a fight.
  • Skill 2's Water damage buff only helps Water-element teammates, useless in a mixed-element lineup.
  • As an SR, good range but slower fire rate than AR/MG.
