Exia — Stats, Skills, Best Teams

Q: Should you pull?

Should you pull?CONSIDER IT — her value is rare wide-scale debuffing, worth pulling if your squad lacks someone to shred DEF/ATK across a crowd; not urgent if you mostly fight lone bosses.

Q: Skill Investment Priority

Skill investment roadmap (Skill 1/Skill 2/Burst): 1/1/1 → 4/4/4 → 7/7/7 → 10/10/10. Why: Skill 1 (debuff) and Skill 2 (self ATK buff) work as a pair, so level them evenly; Burst determines her debuff coverage, so it needs equal investment too.

Review & Analysis

Exia is an Electric Supporter whose kit runs on her stacking buff, Collect Hacking Code. Secret Code builds it on her last bullet — up to 5 stacks, ATK +16.8% each, 15 seconds — and while stacked, Invasion also fires on her last round, debuffing the target's ATK and DEF by 13.77% for 5 seconds. It pays off on her Burst, Partisan Protocol: 122.32% of ATK to the 10 highest-DEF enemies, doubled to 244.64% at full stacks, plus DEF -2.71%. An Electric Team pick, currently tier D.

Skill Investment Priority

Skill 2 first — the stacking engine buffing ATK and unlocking Skill 1's debuff. Burst next as her main AoE damage, doubling at max stacks. Skill 1 last, firing only once stacked.

Skill investment roadmap (Skill 1/Skill 2/Burst): 1/1/1 → 4/4/4 → 7/7/7 → 10/10/10. Why: Skill 1 (debuff) and Skill 2 (self ATK buff) work as a pair, so level them evenly; Burst determines her debuff coverage, so it needs equal investment too.

Strengths & Weaknesses

Strengths

Her burst debuffs DEF on up to 10 targets at once — rare large-scale debuff coverage.
Skill 1 and Skill 2 combo: landing the last bullet while debuffing further lowers enemy ATK/DEF while also buffing her own ATK.

Weaknesses

Needs to land her last magazine bullet to trigger the debuff, so there's some delay tied to her SR fire rate.
No strong single-target damage — she's mainly a debuff support, not a primary Attacker.

Overload Priority
