Sussurro is a 4-star Medic Operator in Arknights belonging to the Medic branch of the Medic class. She's a Vulpo from Siracusa who joined Rhodes Island with one year of combat experience and a confirmed Oripathy infection. Her name comes from the Italian and Portuguese word for "whisper," and despite her low rarity, she holds a unique distinction among single-target healers: when her signature skill is active, she outputs more healing per second than any other single-target medic in the game, including 5-star and 6-star alternatives.
Quick answer: Sussurro's second skill, Deep Healing, doubles her ATK and adds +100 ASPD at max rank, giving her the highest burst healing rate of any single-target medic. The trade-off is that it can only be activated twice per operation.
Sussurro's Stats and Positioning
As a ranged Operator, Sussurro restores the HP of allies one target at a time. Her base attack interval is 2.85 seconds, and her range starts as a 3×3 grid with a 1-tile forward extension, expanding to 3×4 at Elite 1. At Elite 2 with max trust, she reaches 1,345 HP, 488 ATK (plus 60 from trust), and 122 DEF. Her base DP cost is 16, rising to 18 after Elite 1 promotion. She has 0 RES at all promotion levels and a 70-second redeployment timer.
Her potential upgrades reduce DP cost by a total of 2, shave 4 seconds off redeployment, add 23 ATK, and improve her talent at Potential 5. Even at maximum potential, her DP cost sits at 14, which means her own talent never applies to herself.
Minimally Invasive Surgery — Sussurro's Talent
Unlocked at Elite 1, Minimally Invasive Surgery increases healing received by all friendly units whose DP cost is 10 or less, as long as Sussurro is part of the squad. She doesn't even need to be deployed on the map for the effect to work. At Elite 1 the bonus is 10%, scaling to 20% at Elite 2. With Potential 5, those numbers become 13% and 23% respectively.
Despite the in-game description mentioning "Operators," the talent actually applies to all friendly units with qualifying DP cost, including summons and deployable devices. In practice, however, very few commonly used Operators have a base DP cost of 10 or less. The main beneficiaries tend to be fast-redeploy Specialists like Gravel and Projekt Red, low-cost Vanguards like Myrtle, and certain robot Operators. This narrow applicability is widely considered the talent's biggest weakness.
Skill 1 — Healing Up β
Sussurro's first skill is a straightforward ATK buff with auto recovery and manual activation. It lasts 25 seconds at every rank. At Rank 1 it provides +15% ATK, scaling up to +70% ATK at Mastery 3. The SP cost drops from 40 at Rank 1 to 30 at Mastery 3, with an initial SP of 10 at all levels. It's a reliable, repeatable healing boost with no usage limit, making it the safer pick for long operations like Annihilation maps.
Skill 2 — Deep Healing
Deep Healing is the skill that defines Sussurro. It buffs both ATK and ASPD simultaneously, and the numbers are enormous. At Mastery 3, it grants +100% ATK and +100 ASPD for 30 seconds, with an SP cost of just 15 and 0 initial SP. The catch is hard-coded: you can only activate it twice per operation. After the second use expires, the skill cannot charge again for the rest of the battle.
| Rank | ATK Buff | ASPD Buff | SP Cost | Duration |
|---|---|---|---|---|
| Rank 1 | +40% | +40 | 25 | 20s |
| Rank 4 | +55% | +55 | 22 | 25s |
| Rank 7 | +70% | +70 | 19 | 30s |
| Mastery 3 | +100% | +100 | 15 | 30s |
At Mastery 3 with Elite 2 max stats and trust, Sussurro heals a single target for roughly 976 HP per attack while swinging significantly faster than her normal 2.85-second interval. No other single-target medic in the game matches this healing-per-second output during the skill window. The practical effect is that if an ally can survive a single hit from an enemy, they are extremely unlikely to die while Deep Healing is running.
The two-use limit is the primary reason Sussurro sees less play than higher-rarity medics. In most difficult content, you either need sustained healing across an entire operation or you need utility beyond raw HP restoration. Two 30-second windows of extreme healing, while powerful, don't cover every scenario.
PHY-X Module — ...Who Heals Not Herself
Sussurro's PHY-X module adds a new trait effect and stat bonuses across three upgrade stages. At Stage 1, she gains +50 HP, +3 ASPD, and a new passive: when healing allied units below 50% HP, her heal amount increases by 15%. This directly addresses her role as an emergency healer, making Deep Healing even more potent on critically wounded allies.
At Stage 2, the stat bonuses increase to +80 HP and +4 ASPD, and Minimally Invasive Surgery improves to 23% healing amplification for low-cost units. Stage 3 pushes the stats to +100 HP and +5 ASPD, with the talent reaching 25%. Unlocking the module requires Elite 2 Level 40, and the module missions ask you to use Deep Healing a total of 6 times across battles and to clear Main Theme stage 4-7 with a 3-star rating using only your own Sussurro as the deployed Medic.
Base Skills for Rhodes Island Infrastructure
Sussurro contributes meaningfully to your base even when she's not on the battlefield. Her first base skill, Medic Expert α, speeds up Medic Operator Specialization training by 30% when she's assigned as a trainer in the Training Room. Her second skill, Pharmacology β, unlocked at Elite 1, boosts the byproduct rate of elite material processing by 80% when she's working in the Workshop. The Workshop skill in particular makes her a valuable assignment for crafting sessions.
How Sussurro Compares to Other Medics
Sussurro's core problem isn't a lack of healing power — it's a lack of utility. Higher-rarity single-target medics bring secondary effects that often matter more than raw throughput. Silence can deploy a healing drone anywhere on the map. Warfarin buffs an ally's ATK and generates SP. Shining provides massive DEF buffs to nearby allies. Ptilopsis, while an AoE medic, accelerates SP recovery for the entire team. Each of these Operators does something beyond healing that shapes how you build and play a stage.
Sussurro heals harder than all of them during her skill windows, but that's all she does. Her talent targets a narrow pool of low-cost units, and her signature skill has a hard usage cap. In content where sustained healing or strategic flexibility matters — which is most endgame content — the utility medics tend to win out.
Among fellow 4-star medics, however, Sussurro stands well above the competition. Gavial's active healing is weaker and her AoE skill has a long cooldown. Myrrh can be situationally useful in long maps like Annihilation 3, but Sussurro's burst output is far superior in most other contexts. If you lack any 5-star or 6-star single-target healers, Sussurro is the strongest option at her rarity tier and can punch well above her weight when Deep Healing is running.
Promotion Materials
Promoting Sussurro to Elite 1 requires reaching Level 45, plus 15,000 LMD, 3 Medic Chips, 1 Device, and 1 Polyketon. Elite 2 promotion needs Elite 1 Level 60, along with 60,000 LMD, 5 Medic Chip Packs, 10 RMA70-12, and 13 Loxic Kohl. Mastery 3 for Deep Healing costs 6 Skill Summary Volume 3, 2 Polymerization Preparation, and 2 RMA70-24 — a steep investment for a 4-star, but the payoff is a skill that doubles her ATK and dramatically accelerates her attack speed.
Sussurro's Lore and Background
Sussurro is a young Vulpo woman, 142 cm tall, born in Siracusa on September 4th. Her character design is based on the red fox (Vulpes vulpes). She contracted Oripathy while volunteering as a medical student, likely through contact with active Originium in infected blood during patient care. Her diary entries describe a methodical, analytical mind — she documented her own infection onset with clinical detachment, noting fever and headaches she initially mistook for overwork before discovering Originium crystals on her body.
Her search for a specialized organization to research and treat Oripathy ultimately led her to Rhodes Island. She has an Operator Record titled "Professional Doctor" and a Paradox Simulation called "First Aid." Her illustrator is 将, and she's voiced by Haruka Terui in Japanese, Cassandra Lee Morris in English, Yue Xin in Chinese, and Seo Yu-ri in Korean. She was introduced during the Heart of Surging Flame event and has since received two outfit skins: Summer Flower FA026 and Travel Freely.
Sussurro occupies an unusual niche in Arknights. She's a 4-star Operator with a skill ceiling that rivals or exceeds 6-star medics in raw single-target healing output, but her limited skill charges and narrow talent keep her from becoming a staple pick. For players building up their roster or facing stages where a single ally needs to survive extreme burst damage, she remains one of the most efficient investments in the game. Just don't expect her to do anything besides keep someone alive — because that's the one thing she does better than almost anyone.
