Rosie is one of those support heroes that doesn’t just stand behind the team healing quietly—she actively shapes how your squad performs.
She’s built around protection, utility, and a unique ability to mess with enemy buffs while also reviving allies when things go south. If you’re looking for a support that mixes survivability with clever control, Rosie is your girl.
Rosie Guide – Team Build, Lineup, Skills (7k ReBIRTH)
Passive – The Core of Her Support
Rosie’s passive is a lifesaver in multiple ways. First, she gets a Max HP-based Defense boost, which scales naturally as you build her tankier. That means she doesn’t fold as easily compared to other supports. More importantly, when her health dips to 50% or below, she automatically gains all damage immunity for two turns. This trigger gives her a chance to reset, survive burst windows, and keep helping the team.
The real kicker, though, is her team utility. She grants Effect Probability Boost to all Tank and Universal allies. This means any crowd control, debuffs, or status effects your frontline tries to land will connect more reliably. In battles where landing a stun, burn, or debuff is the difference between winning and losing, Rosie amplifies your chances.
Basic Attack – A Touch of Damage
Her normal attack hits two enemies, scaling off her MATK and a percentage of her max HP. It’s not game-changing damage, but since it ties into her stat scaling, it adds a bit of pressure without distracting from her role.
Skill 1 – Shadow of Death
This is an AoE attack that hits all enemies twice, using the same MATK and max HP scaling. Each strike also has a chance to apply Death, a powerful status effect that functions like a ticking time bomb. Enemies under Death lose a chunk of HP each turn, and if it stacks, they’re gone instantly.
At higher enhancement levels, this skill not only hits harder but also raises the odds of inflicting Death while adding Effect Resist Reduction. That combination makes enemies more vulnerable to all status effects from your team, not just Rosie’s.
Skill 2 – Gift of Return
This is Rosie’s strongest support tool. She revives fallen allies, initially targeting two of them, bringing them back with a decent chunk of HP. Once you enhance the skill, that revive becomes stronger, and the revived allies also gain Guts, letting them survive a killing blow once. It’s a huge safety net that turns around matches.
And she doesn’t just stop at reviving. On top of that, her skill reduces the duration of enemy buffs across the board, stripping away those annoying shields or long-lasting attack boosts. It’s both a recovery and a control tool rolled into one, which makes her stand out compared to more straightforward supports.
Transcendence – Teamwide Support
Rosie’s transcendence is where her utility explodes. The revive that originally targeted two allies now expands to all allies. Combined with the added Guts effect, this turns her into a team-wide reset button. Meanwhile, her passive’s Effect Probability Boost also improves, making sure your Tanks and Universals almost always land their important debuffs. At this stage, Rosie becomes a must-have anchor for many team comps.
How Rosie Works in Practice
On the battlefield, Rosie thrives in longer matches where survivability and control matter more than raw damage. She’s the kind of hero that keeps your frontline sticky while giving your damage dealers more reliable crowd control. Her revive skill prevents snowballing after a bad start, while her AoE skill adds consistent pressure with Death.
She pairs especially well with heroes that rely on status effects to lock down the enemy—think burners, stunners, or defense shredders. Tanks benefit massively from her Effect Probability boost, letting them lock enemies down more consistently.
Rosie isn’t the flashiest hero, but she’s a stabilizer. She gives your team breathing room when things get rough, denies the enemy’s buffs, and ensures your own allies’ effects stick more often.
If you like playing methodical, control-heavy strategies, Rosie can feel like the glue that holds everything together. With enhancements and transcendence, she evolves from a good support into a cornerstone unit for both PvE and PvP.
