RIIC Base Skills
Quick Evaluation
+ Can be useful early game with small investment.
- Very weak skills means he has no long term value.
- S2: Range limitation often hurts more than it helps.
- S1: Low impact skill that requires lots of micromanagement.
- Despite higher costs, Honeyberry is available to everyone in the red cert shop and is significantly better.
Operator Overview
Chestnut may look like a Pokemon trainer, but instead of small combat monsters, his focus is collecting gemstones. He works at Rhodes Island as a gemologist and crystal therapist, using his Originium Arts to bring out the natural healing powers of his crystal collection and soothe wounds both physical and psychological. Chestnut is quite the unique addition to the Arknights cast: he’s the first male 4* Medic, the first Durin Medic, and the first 4* Wandering Medic, able to heal Elemental Damage as well as regular HP damage, much like his predecessors Mulberry and Honeyberry.
His Down to Earth Talent is simple but extremely appropriate to his geology-focused background—it increases the amount of Elemental Damage that Chestnut heals to ground-deployed Operators. His S1, Tiny Stockpile, greatly increases the Elemental Damage recovery of his next heal and can hold multiple charges, which can result in a surprising amount of burst-Elemental-healing for a single target. Similarly single-target-focused but for a longer period of time is his S2, Earthen Surge. This Skill changes Chestnut’s healing range to a straight line in front of him, but it greatly increases his ASPD and causes his healing and Elemental recovery to ramp up over time if he is consistently healing the same unit. Earthen Surge is geared towards healing a single tank unit deployed directly in front of Chestnut, while Tiny Stockpile is preferable for dispensing spot heals over a wider area.
Chestnut’s kit is fun and thematic, but it can’t exactly be called flawless. His Skills have uncomfortably high SP costs (especially Earthen Surge), and while Chestnut can heal a fair amount of Elemental Damage, it can be difficult for him to output respectable HP healing. Tiny Stockpile doesn’t increase his HP healing at all, and Earthen Surge’s SP cost and ramp-up time are both so high that it cannot be used with any frequency. Earthen Surge also has the downside of greatly reducing Chestnut’s healing range, which is one of the primary strengths of the Wandering Medic archetype. While the range reduction does help Earthen Surge ramp up in the way it’s intended to do, the Skill’s design pushes Chestnut to heal only one target for the duration (and the duration isn’t even that long). This can be problematic, as Elemental Damage is often spread across multiple units or even your entire team, rather than being focused on just one target. The biggest problem for Chestnut, however, is his competition. 5* Wandering Medic Honeyberry is easily available in the Red Certificate store at the time of writing, giving players access to a guaranteed non-gacha Wandering Medic who provides more reliable Elemental Healing across her entire healing range.
There is potential to use Chestnut as a supplement to another, stronger Medic, Wandering or otherwise. He does best when focusing on a single ground-deployed target (even with S1), so if you’re able to funnel most of the Elemental Damage on a map into a single Defender on a chokepoint, Chestnut can focus entirely on that one Defender while another Medic handles healing for the rest of your squad. It’s hard to argue that Chestnut is an especially powerful Medic, but you certainly can’t argue that he’s a dedicated one!
Newbie Tier List Explanation
For early game players struggling with elemental damage, Chesnut is a decent option that is cheap to develop. However, he is a poor healer, and often won't be able to handle the healing load. Honeyberry is much better at the role, and can be purchased with red certs, so players that don't need the Chip Catalysts for early E2s can consider her instead.

Note: This unit does not have Mastery grades. This means the unit is generally not one worth spending the resources of Mastery on. However this write-up should help with skill selection, should you want to use the unit regardless.
Chestnut can be a decent Medic since the archetype is strong by default, but he has two fatal flaws. For one, he pales in comparison to Mulberry and Honeyberry (who everyone has access to). For two, both of his skills are very limited. His S1 is a mediocre skill in isolation, with a middling utility and a lot of micromanagement required to maximize. And while his S2 has better effects, the range restriction removes one of the biggest advantages of the archetype. Activating S2 can frequently hurt more than it helps! Most people should not spend the resources to Master either of his skills, though if you are especially intent on using him, you will likely find some use in both.

Increase Trust to 50.From what Chestnut told us, the Druins often use all kinds of crystal lights for lighting, and he has long had an interest in these colorful crystals, even hoping that he could one day mine these beautiful rocks himself. Dreams are always the best motivator, and even though most Durins are lively in nature and dislike confinement, to make his small childhood wish come true, Chestnut learned every last detail he could from the adults in his tribe about these ores. When he dug his first crystal out of the ground and unleashed its colorful radiance, he excitedly made a small lamp out of this ore. Even though this small crystal lamp isn't particularly well-made and its light's color isn't especially vivid, it is still one of Chestnut's favorite possessions.
When they spend their entire lives living underground, it is very important to the Durins to continue to build and expand their underground cities. They must first survey the geological features of their destination to determine whether it is suitable for habitation. The adults who taught Chestnut his geological knowledge became his teacher, and in this underground world where there isn't a clear concept of occupation, they formed a close relationship built upon knowledge and enthusiasm. Whenever the city had to be expanded, Chestnut and his teachers would put all their knowledge and power to use to repay their homeland.
After Chestnut made it to the surface, he changed course and instead walked the path of a doctor. Although his teachers and friends couldn't understand his fixation on the surface, they took notice of how he persisted down this path quietly and decided to support the boy who's so fond of researching his interests. After all, there are many ways that one can live. As long as you are happy and you aren't affecting anyone else, who could say that's the wrong way to live?
He gave me a small ore as a present and said it's unique to the Durins. That's so cute!

Increase Trust to 100.One day, a Catastrophe occurred on the surface directly above Chestnut's homeland by coincidence and triggered a larger scale cave-in, which destroyed a substantial portion of the underground city. Although the situation on the surface was unclear, the underground structure had already been altered. Chestnut understood that his homeland needed his help. He traversed the fissures opened by the Catastrophe, collected samples and ores, and recorded data that could affect his homeland. By the time he was finished with his work, half a year had passed. His tribe repaired much of the rail tracks and elevators thanks to the data that he and the other prospectors collected, and the only things left could only be healed with the passing time and continued effort. Having seen everything turn out so successfully, Chestnut finally had the time to explore the question he had at the very beginning: 'Just what happened on the surface?'
When he was still a kid, Chestnut was already struck with admiration of the surface, having heard how vast and wide it was on the surface from adults that had been there. He was perhaps even more of a fan of the surface than the unique landscapes underground. Chestnut worked on his plan to climb aboveground day after day, and even though reality wasn't quite how he imagined, he didn't let it get to him. Ignoring the fissures that led aboveground and the glimpses of the blue sky above during his geological surveys, Chestnut instead turned his attention to the ground under his feet.
With the way things are now, Chestnut decided to take the chance to do some traveling. He rode the newly repaired elevators traversed layers after layers of dark but differing geological cross sections, and finally made it above ground for the first time. He kept going, and aside from that narrow blue above he ignored during his surveys, he saw a lot of landscapes that even the tribesmen who returned from surface never saw: a large, bottomless valley; a wide, calm lake; and strange, wind-eroded rocks. Yet he also saw something that's the furthest away from beauty for the first time: the land-dwellers' blood-soaked wars. After everything came to an end, Chestnut asked them about the cause. Apparently, a group of bandits attempted to steal the farmers' harvest, leading them to fight back. Born and raised in the underground where items are traded peacefully, he didn't understand why this happened, but he felt there was something for him to do, and so he raised his staff and offered this group of men a helping hand.
Although his hometown is habitable after it was repaired by his tribesmen, Chestnut has already made the decision to remain on the surface. He chose to follow his childhood dream. What's more, there are a lot more people here who need his help.

Increase Trust to 150.That said, the operators and Chestnut himself both overlooked one thing during his onerous missions, and that's how humans must, aside from work, also pay attention to how they feel in their hearts. Chestnut encountered a problem that almost every doctor encounters at some point during their practice: It seems that simply being a doctor doesn't affect much.
One day, after the field operations squad had completed all the preparations for their evacuation, they found Chestnut standing on a patch of muddy field when they called roll. He didn't respond to their calls, even casting his Originium Arts into the sky in a retaliatory way.
After he got back to the landship, Chestnut told our Medical Department's operators his misgivings: With pain caused by sickness, he believes that as long as he keeps putting in the effort, even the most stubborn of diseases can be defeated. But after he came to the surface, he realized just how many of the injured were wounded by conflict. Their pains weren't caused by disease, but something much more complicated that he is unsure of. He can treat them, but he cannot stop those more complicated reasons from happening. In particular, through his work in Rhodes Island, he has had much more chances to see for himself how ugly war is.
Chestnut started to crumple.
He looked at this strange, beautiful world and began to reminisce his homeland.
And so, Rhodes Island approved his leave request.

Increase Trust to 200.During his vacation, Chestnut started to work his old job of geological prospecting and crystal ore mining again. On his free time, he visited the waterfall he used to visit as a kid and compare his height to the fluorescent mushrooms there. This slow-paced life gave him more time to think: What is it that I wanted to do in the very beginning? What am I so distressed about? Is the thing that's giving me all this anxiety something I can solve if I put myself to it?
Just like when he worked as a geological prospector to help his tribesmen, although a Catastrophe striking his homeland was vexing, he knew there was nothing he could do to stop Catastrophes. In that case, saving others as a doctor should be no different. He knew there was nothing he could do to stop the conflicts between people, and he must accept that.
Chestnut spent over a month to carefully think about all this. He didn't know if this was just a fake sense of optimism for self consolation, but he felt he couldn't let what he had no control over to drag him down any longer. He chose to return to work, as only then will he be able to find the right way to solve these problems.
When Chestnut returned to Rhodes Island, it was obvious that he now had a much firmer conviction. Although psychological scars cannot be completely erased within such a short amount of time, everyone at Rhodes Island is happy to see him moving forward once again.

Appointed as Assistant | Um, Doctor, the documents on the shelves are a bit messy. Back home, I had a tabletop assistant device that automatically organized our files. All you had to do was stick the files in, then it would package and seal them. I think you should get something like that too. |

Talk 1 | Wanting to see new places is a pretty common reason for leaving home, isn't it? But every time I climb a tall mountain or dive into a deep lake, I feel like I've made the right choice. |
Talk 2 | Doctor, are you fan of wide-open landscapes? For example, imagine yourself next to a lake, watching the surface of the water rise and fall, the clouds gathering and dispersing, the sun slowly drooping behind the horizon, painting the lake a dazzling gold... That's the kind of scenery I love. |

Talk after Promotion 1 | My staff turns minerals into healing agents, sometimes with other special effects depending on the type of material used. Don't believe me? I'm being serious here, Doctor! |
Talk after Promotion 2 | I've helped more and more people, which gives me a sense of accomplishment. But as a physician, I still wish there were fewer and fewer casualties from people fighting each other. |
Talk after Trust Increase 1 | Doctor, have you seen fluorescent mushrooms before? There used to be a bunch of them growing by the rocks near the waterfall I played at as a kid. Some of them grew taller than the tallest person in the clan, bringing light to places where the city could not reach. |
Talk after Trust Increase 2 | My original reason for coming above ground was simple – I wanted to survey the geography around my homeland, and soak up the sights and sounds along the way. But the more I traveled, what kept me up here wasn't the places I had been, but the people who needed my help. |
Talk after Trust Increase 3 | Doctor, why do people bloody themselves fighting each other? I can treat a wound or two, maybe even a lot more than that, but what can I do as a physician if we can't change their minds? |
Idle | Your desk is still a bit messy. Let me clean things up for you. |
