Ember is a 6★ Defender in Arknights Endfield built around one simple promise: you can take hits, keep moving, and your team stays standing. She mixes Heat damage, Knock Down control, on-hit healing, and team-wide Shields into a kit that is hard to disrupt and easy to feel in real fights.

Analysis & Verdict
Ember’s kit is built around getting hit without losing the fight. Forward March is a proactive engage: a Heat slam that knocks enemies down and adds Stagger pressure. The extra clause matters because it rewards real combat—if she takes damage during the cast, she generates more Stagger when the slam lands. In practice, it’s a “walk into the mess and still win the trade” button.
Frontline Support is the defensive glue. The trigger is simple: the controlled operator gets attacked. Ember answers by leaping in, knocking the target down, and healing the controlled operator. This makes her protection feel immediate, because the response is tied to the moment you actually take a hit, not to a timer you have to predict. Will scaling pushes this further by turning her into a real healer, not just a tank with a small top-up.
Re-Ignited Oath is the team stabilizer. It deals Heat damage, but the important part is the Shield to every teammate based on Ember’s Max HP. That shield changes how your team plays: you can commit to rotations during pressure, because the team gets a buffer that doesn’t require target selection. Potentials make this even more blunt: cheaper ultimate cost, stronger shields, and an ATK bonus while the shield is active.
Her talents explain why she feels “comfy.” Inflamed for the Assault gives Protection and interruption resistance during the two skills you cast most often in danger. That means she is less likely to get stopped mid-animation, which is where many defenders lose value. Pay the Ferric Price then turns incoming damage into an ATK ramp, so even when she is tanking, she is not entirely dead weight.
The only trade-off is that her personal damage ceiling is not what you pick her for. You pick Ember when a team needs to survive, maintain rotation flow under pressure, and stop getting knocked off-script by random hits. If you want a defender that makes runs feel stable, Ember does exactly that.

Don’t Want to Level and Promote Ember Yourself?
Ember scales with Promotions and Potentials, especially for Shield strength, healing reliability, and the protection window that keeps her casts uninterruptible. Building her alongside multiple operators can slow down overall progression.
