Should you pull?
Should you pull?
YES — Viper is both a solid damage-dealing Attacker and a self-contained ATK/Hit Rate team buffer from the start of the fight, plus high survivability from target-avoidance. Well worth pulling if you lack a Water Attacker or need a flexible buffer-dealer for the Exotic squad.

Skill Investment Priority
Skill investment roadmap (Skill 1/Skill 2/Burst): 4/4/4 (functional) → 7/4/7 → 10/4/10 (endgame). Why: Skill 1 (whole-team ATK/Hit Rate buff) affects the whole squad so it's as high priority as Burst (main-target DEF-down); Skill 2 only helps her own survival so it can wait.
Strengths & Weaknesses
Strengths
- Skill 1 auto-buffs ATK by 28.98% and Hit Rate by 11.13% for the ENTIRE SQUAD as soon as the target appears — triggers early, no complex conditions needed.
- Burst lowers the stage target's DEF by 19.83% for 10 seconds when it matches the designated target, opening the door for squad-wide damage.
- Skill 2 removes herself from enemy targeting and grants 1 second of invincibility on Full Burst — rare survivability for an Attacker.
- As a Shotgun user, normal attack damage is high (220.4% ATK per hit) at close range.
Weaknesses
- Burst's DEF-down only applies if the target matches the stage's designated target, which isn't always the case.
- Shotgun range is short, a disadvantage against long-range bosses/enemies.
- Skill 2's target-avoidance effect ends the moment Viper takes damage — not absolute invincibility.
