Atun Ro'kaill's skills as a medic are not just limited to holo-books and lectures. He has read up and practiced a handful of experimental treatments while inventing a few home remedies of his own. This allows Atun Ro'kaill to work outside the box in less than ideal situations, and can lead to him solving mysteries other trained medics might struggle with. This, of course, comes with its own string of failures, as nothing is ever perfect.

Atun Ro'kaill looks at any problem he comes across and instead of immediately complaining about it sets out to figuring out a solution. He will work tirelessly to find workarounds or a solution, but can often overthink the resolution and come up with a "fix" that is actually more complex than needed. This driven approach to fixing problems can be helpful at times but grating at others when a simple "restart" would have accomplished the task quicker than re-programming the entire device.

Atun Ro'kaill has been patching up the wounded for years as a Medic and has come to the conclusion that more often than not, the injuries are either self inflicted or deserved. While he will always work tirelessly on behalf of his patient in an ongoing quest to preserve all life, that doesn’t stop him from scolding or belittling patients that he feels should know better than to walk into a rancor pit with a bucket of raw meat. Atun Ro'kaill teeters on the line between compassion and supporting selective evolution, which can make him come off as less friendly or inviting than other medics.

Atun Ro'kaill likes to engage in detailed discussions and think through situations carefully, often collaborating with others to seek their opinions before deciding on the best course of action.

Sometimes the only way to prepare for the worst is to always expect it. Atun Ro'kaill takes this philosophy one step further by never leaving home without accounting for every possible scenario he might expect to encounter. Atun Ro'kaill tends to always have the right tool or item for a situation and has a habit of quietly and almost smugly presenting solutions before anyone even recognizes there is a problem. This foresight is far from infallible, however, and he often finds himself at a loss in situations that go beyond what he could have imagined. While incredibly practical and often a life-saver in a pinch, his perpetually pessimistic outlook on daily life can be a bit draining on more optimistic-inclined companions.
