Sussurro in Arknights — The 4-Star Medic With the Highest Single-Target Healing Output

Sussurro is a 4-star Medical Medic in Arknights who occupies a strange place in the game's roster. She has the highest single-target healing rate of any Medic when her signature skill is active, yet she rarely appears in optimized team compositions. The tension between her raw healing power and her lack of broader utility makes her one of the more interesting low-rarity operators to evaluate.

Quick answer: Sussurro's second skill, Deep Healing, simultaneously buffs her ATK and attack speed, producing the strongest single-target healing output in the game — but it can only be activated twice per operation, and her talent only benefits operators with a base DP cost of 10 or lower, limiting her overall versatility.

Sussurro's Profile and Background

Sussurro is a Vulpo from Siracusa who stands just 142 cm tall. She's a fully qualified medical professional — not a child, despite what her appearance might suggest — and her operator file lists her recommendation as "Professional Doctor." Her Oripathy infection has been confirmed, with Originium crystals visible on her body. She was introduced during the Heart of Surging Flame event and is obtainable through both Headhunting and Recruitment.

Her birthday falls on September 4th, and she has one year of field experience with Rhodes Island. Despite her small stature and youthful look, the community has long noted that she's an adult who completed medical training, a detail that often gets overlooked because of her design. Her voice actresses include Haruka Terui (Japanese), Cassandra Lee Morris (English), Yue Xin (Chinese), and Seo Yuri (Korean).

Deep Healing — Sussurro's Defining Skill

Sussurro has two skills. The first, Healing Up β, is a straightforward ATK buff that increases her healing per tick. It's serviceable but unremarkable. The real draw is her second skill, Deep Healing, which greatly increases both her ATK and her attack speed while active. The combined effect of hitting harder and hitting faster makes her healing-per-second output exceed that of every other single-target Medic in the game during the skill's duration, including 6-star operators like Shining.

The catch is significant. Deep Healing can only be used twice in a single operation. After the second activation expires, the skill cannot be charged again for the rest of the map. This means you need to be deliberate about when you press the button. Wasting an activation on a low-pressure wave leaves you without it when things get dangerous later.

At E1 Level 40 with maximum trust, Sussurro's baseline healing rate already edges out Shining at the same investment level thanks to her talent providing a small passive boost to low-cost allies. Once Deep Healing is active, the gap widens dramatically. The skill's 70-point attack speed buff, combined with its ATK increase, creates a healing window where almost any operator can survive sustained incoming damage, provided they don't get one-shot.

Minimally Invasive Surgery — A Narrow Talent

Sussurro's talent, Minimally Invasive Surgery, amplifies the healing received by any operator in the squad whose base DP cost is 10 or lower. This is a passive, squad-wide effect that doesn't require Sussurro to be the one healing them.

The problem is that very few commonly used operators actually meet that DP threshold. Fast-redeploy specialists like Gravel and Projekt Red qualify, as do some low-rarity Vanguards like Myrtle. A handful of higher-rarity operators with naturally low costs, such as Sora, also benefit. But most of the operators you'd want to keep alive in difficult content — Defenders, Guards, and other frontline units — cost well above 10 DP. Sussurro herself costs 14 DP even at maximum potential, so she doesn't benefit from her own talent.

The talent finds its best use in low-rarity challenge runs or in niche strategies where you're specifically trying to keep a cheap operator alive under heavy fire. Outside those scenarios, it's effectively dead weight compared to the universally useful passives offered by competing Medics.

PHY-X Module — ...Who Heals Not Herself

Sussurro's operator module, titled ...Who Heals Not Herself, adds a conditional healing bonus. When she heals a friendly unit whose HP has dropped below 50%, the healing effectiveness increases by 15%. The module also raises her maximum HP and attack speed. At higher upgrade levels, the Minimally Invasive Surgery talent receives an enhanced healing multiplier.

Unlocking the module requires promoting Sussurro to Elite 2 Level 40 and reaching 100% Trust. The module reinforces her identity as a burst healer who excels at pulling operators back from the brink, though it doesn't address her fundamental lack of utility beyond raw healing numbers.

Why Higher-Rarity Medics Usually Win

Sussurro's healing output during Deep Healing is genuinely unmatched. So why does she rarely appear in recommended team compositions? The answer comes down to what the rest of the Medic roster brings beyond healing.

In most Arknights content, the healing demands on a Medic are moderate enough that any competent healer can keep the team alive. What separates the top-tier Medics is what they contribute when healing isn't the bottleneck. Ptilopsis accelerates skill charge times for the entire team. Silence can drop emergency healing anywhere on the map. Warfarin turns your strongest DPS operator into an even bigger threat. Sussurro heals harder than all of them, but that's all she does.

Operators like Saria and Angelina can also fill healing roles while contributing damage or crowd control, further reducing the situations where a dedicated burst healer is the optimal choice. Even Myrtle, a Vanguard, provides meaningful team healing through her second skill while generating DP.

When Sussurro Earns Her Spot

Sussurro is at her best in accounts that lack 5-star single-target Medics. If you don't have Silence, Warfarin, or similar options, Sussurro is a clear upgrade over other 4-star Medics like Gavial and Myrrh. Gavial lacks any meaningful active healing buff, and Myrrh's dual-target healing, while useful in Annihilation maps, doesn't match Sussurro's peak output.

She also shines in specific challenge scenarios where a single operator needs to survive extreme incoming damage for a limited window. Contingency Contract maps with high-risk modifiers can create situations where Deep Healing's burst is exactly what's needed to keep a key blocker alive through a dangerous wave. The two-use limit matters less in these contexts because the entire strategy often revolves around surviving one or two critical moments.

Low-rarity or restricted-operator challenges are another natural fit. Her talent actually becomes relevant when the squad is full of cheap operators, and her healing output punches well above her rarity.

Base Skills and RIIC Value

Outside of combat, Sussurro contributes meaningfully to your base. Her first base skill, Medic Expert α, speeds up Mastery training for Medic operators by 30% when she's assigned as a trainer in the Training Room. Her second base skill, Pharmacology β, boosts the byproduct rate of upgrade material processing by 80% when she works in the Workshop. The Workshop bonus in particular is quite valuable, as higher byproduct rates translate directly into material savings over time.

Sussurro is a specialist in the truest sense — she does one thing better than anyone else in the game, but only that one thing. For players building out their roster or tackling content where raw healing throughput is the deciding factor, she's an excellent and resource-efficient investment. For everyone else, the utility offered by higher-rarity Medics will usually provide more value across a wider range of situations. She's not underrated so much as correctly rated: exceptional at healing, limited in everything else.
