Q: Should you pull?

Should you pull?CONSIDER IT — An international community tier list ranks Rosanna: Chic Ocean A in Story, but a mode-by-mode community tier list only gives her A for Solo Raid and "-" everywhere else, showing she's a narrowly specialized buffer rather than a universal pick. Worth pulling if you regularly fight bosses/raids with detachable-part mechanics (arm shields, shoulder armor, etc.) and need dedicated part-damage buffs. General players or those focused on campaign/PvP should save gems for a more versatile Supporter.

Review & Analysis

Rosanna: Chic Ocean is a Wind Supporter manufactured by Tetra, wielding an Assault Rifle in the Underworld Queen squad. Skill 1 "Ferita" raises the whole team's damage to Parts by 24.26% for 15 seconds on entering battle, and each time an ally or herself destroys an enemy part, the team stacks 3% ATK (up to 5 times for 30 seconds). Skill 2, the active "Spina di Rosa" (30s cooldown), again raises team damage to Parts by 24.26% for 15 seconds, and deals 70.4% of final ATK as sustained damage per second to the nearest enemy for 15 seconds. Her Burst "Onda Grande" (20s) raises the team's sustained damage by 20.32% for 10 seconds and increases all enemies' damage taken by 32.23% for 10 seconds. She functions as a Parts-break and sustained-damage buffer, well suited to teams exploiting Interruption Parts mechanics or stacking multiple continuous-damage Attackers.

Spina di RosaSkill 2

Affects all allies. Damage to Parts ▲ 24.26% for 15 sec. Affects the enemy nearest to the crosshair. Deals 70.4% of final ATK as sustained damage every 1 sec for 15 sec.

Skill Investment Priority

Prioritize Skill 2 (active, repeats the Parts-damage buff plus sustained damage, short cooldown) → Burst (sustained damage buff plus enemy damage-taken debuff) → Skill 1 (ATK stacking depends on parts destroyed, less consistent).

Skill investment roadmap (Skill 1 / Skill 2 / Burst — general priority): 1/1/1 (functional) → 4/4/4 → 7/4/7 → 10/7/10 (endgame). Why: Skill 1 (self-ATK stacking from part destruction) and Burst (sustained damage buff + enemy debuff) are her two main power sources, so prioritize them together; Skill 2 scales steadily but matters less.

Strengths & Weaknesses

Strengths

All three of her skills revolve around part-damage buffs, clearly specialized for an armor/shield-breaking playstyle.
Skill 1 also self-stacks ATK every time an ally or herself destroys an enemy part, growing stronger the longer the fight goes.
Her Burst buffs both sustained damage and enemy damage taken, useful even on stages that don't require part-breaking.
As a Burst II Supporter, she slots easily into standard campaign comps.

Weaknesses

An international community tier list ranks her A in Story, but a mode-by-mode community tier list only gives her A for Solo Raid and "-" (unusable) for Stage/Anomaly/Tribe Tower — a narrow window outside of raid content.
Her part-damage buffs are nearly meaningless against enemies without a detachable-part mechanic (most regular enemies).
No healing or strong CDR tools — purely a specialized offensive buffer.
As a Burst II unit she's less flexible than Burst I when you need to burst urgently.
