Operator Overview
Name in Cyrillic: Истина
Meaning of name in Russian: Objective Truth
“You want to praise us? Do it now, then!”
For the sake of maintaining her reading privileges, Istina leverages her sociological knowledge and her control-type Arts to support Rhodes Island. A Supporter Slower Operator who deals Arts-based damage, Istina uses her spells to inflict DPS and to Slow the enemy’s advance.
Among the Slow-focused Supporter units, Istina stands out for her second Skill, Literature Storm. When activated, Literature Storm increases Istina’s ATK power, her range, and the number of enemies she can attack at once. Being able to Slow multiple targets over such a wide range can stop any enemy wave dead in its tracks, creating plenty of time for the rest of your team to pick the enemies apart. This power is bolstered by Istina’s Explorer Talent, which increases her attack speed, allowing her to apply her Slows more frequently and consistently.
Explorer does come with a drawback: it lowers Istina’s DEF, which is already one of the lowest in Arknights, meaning she needs to be protected in her placement. Her ATK is also noticeably lower than dedicated Caster Operators, reducing her direct damage potential. But despite her ATK, Istina can be an effective damage contributor in her own way because of her cheap DP cost, her large attack range, and her S2’s multi-target capabilities.
Newbie Tier List Explanation
Her S1 offers consistent slowing and S2 is a multi-target slow available at E1.
Skill Discussion
 |
S1M3 | None | ||
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.
Istina lacks the utility of most Supporters. Her kit is really only her archetype slow and some mediocre damage. That mattered a bit more when class bans were more common and options were more limited, but it has little value in the current game. However, Istina is reasonably popular and still more than usable should you desire. Both of her skills have value, but I strongly favor her S1 for Mastery. It has higher DPS, total damage, and at M3, 100% uptime slow against one target. Of course, her S2 can hit three targets in a bigger range, so it has value as well. Her Module brings S2 to *almost* 100% uptime on the slow, but S1 remains the better skill for where you might actually use her, and doesn’t require a costly Module.

Increase Trust to 25.Istina is cool-headed and rational, though somewhat introverted. She often absorbs herself in her hobbies: the meticulous study of more profound Originium Arts, the study of the latest social theories, observation of others and their relationships, and fashion.
Over the course of her multiple interactions with the Ursus Student Group, Istina displayed rare communication abilities and an assured manner, and gave clear and focused answers. We are certain that Istina intends to hold proactive exchanges with Rhodes Island, and may be a positive factor in communication with the Ursus Student Self-Governing Group.

Increase Trust to 50.It is now known that the 'Ursus Student Self-Governing Group' was originally proposed by Istina. The group's establishment helped the Ursus students work together and get past the initial phase of isolation and mutual distrust.
During consultation, Istina keenly answered several questions concerning Zima. Istina believes that although Zima is rude and sometimes unreasonable, she attaches great importance to her companions in the Self-Governing Group and is a competent leader. And if she could add her own input during operations, this would be even better.
While discussing Zima, the Doctor made many pointed remarks, but Istina gave opposing opinions. Istina believes that Zima will not become a destabilizing force for Rhodes Island, and that to believe that her amibitions extend only as far as Rhodes Island would be to underestimate her.

Increase Trust to 100.Istina was born in Chernobog, a city in the Empire of Ursus. Her parents were both employed in local agencies. During the periodi riots by student organizations, Istina declined to participate and instead chose to read quietly. As she had no interest in the loud music and partying of her peers, she began to read some particularly interesting books coming out of Londinium, Victoria at the time. From these, she started to reevalute everything she thought she knew, and began to see everything in a new light.
Archive File 4
Increase Trust to 150.With regard to her whereabouts during the Chernobog incident, Istina modestly and succinctly declined to answer, but she showed several changes of emotion in doing so. On account of Rhodes Island's current policies and the need to protect certain company secrets, investigations into the Ursus Student Self-Governing Group have temporarily ceased.
In view of the background investigation into the Ursus Student Groups, there is no need to question Istina's background. Because of this, it is advisable to use psychologically founded methods to communicate with Ursus students. Future options for cooperation should be provided based on the suitability and independence of the student union members.
Note: Based on Istina's intense level of interest in the books in the Doctor's office, it is advisable to give her a degree of reading privileges.

| Appointed as Assistant | Greetings, I'm here for my shift… That's a peculiar look on your face. Do I seem so unreliable? |
|---|---|
| Talk 1 | We don't throw ourselves into battle because we want to. We just have a stronger will to survive than most. If you understand, that alone would be enough. |
| Talk 2 | Zima, the girls, and I all came from different schools. But all the students in the city knew the legends of General Zima. Doesn't that sound cool? Literally. Zima is Ursine for 'winter', you see. Hm, yes. |
| Talk 3 | How did we escape from Chernobog? Hmm... you really don't want to know. Sometimes the truth is better left untold. |
| Talk after Promotion 1 | Oh? I'm reading a mystery novel… As a matter of fact, it taught me some lessons that proved useful in getting me through that terrible time. |
| Talk after Promotion 2 | My favorite books? Hmm, I enjoy topics like politics, economics, and dialectical materialism… Baking magazines and stuff like that are nice too. |
| Talk after Trust Increase 1 | Home? My hometown? Obviously, we can't go back there. You know as well as I do that there's nothing left of it. Even if we rebuilt Chernobog, I still… |
| Talk after Trust Increase 2 | Rhodes Island is safe. And there are so many books here in your office... If I could, I'd really prefer to stay here… |
| Talk after Trust Increase 3 | What will I do in the future? Hmm… No idea. My books don't have an answer for that. I hope someone will give offer me one, someday… |
| Idle | Such a twist is beyond my imagination. 'Every last one of the passengers on this train, you're all murderers!' |
| Onboard | I am Istina. I'm still a student, but I was recruited for my ability to use Arts… Yes, it is rather strange for a student to serve here, isn't it? |
| Watching Battle Record | You want me to be stronger? |
| Promotion 1 | Do you feel like you understand me better now? Naive, you're far from really knowing me. |
| Promotion 2 | Now that you've offered me such recognition, I will reveal my true power. Allow me to demonstrate by reducing this office to a fine powder… Just kidding. There are too many precious books here. I would never do something so awful. |
| Added to Squad | Understood. |
| Appointed as Squad Leader | Hmm… The team is somewhat different from what I imagined. |
| Depart | Let's show our determination, earnestness, and boundless passion. |
| Begin Operation | May the star of victory shine upon us. |
| Selecting Operator 1 | What is it, Doctor? |
| Selecting Operator 2 | Go ahead. |
| Deployment 1 | I have a distaste for war. |
| Deployment 2 | It seems we must fight. |
| In Battle 1 | Come at me. |
| In Battle 2 | Please, no need to rush. |
| In Battle 3 | Let us take it slow. |
| In Battle 4 | Time to teach you a lesson. |
| 4-star Result | Why do they fight... even when it may cost them their lives? What do they gain from it? |
| 3-star Result | Doctor, if you have to commend us, now is the time. |
| Sub 3-star Result | Those enemies who fled... We probably won't see them again. |
| Operation Failure | Neither our numbers nor our efforts were sufficient… |
| Assigned to Facility | A secret room, where, shall we say, interesting things happen. |

Description:
Should you read word by word or fly through lines at a time? It's not a question worth vying over to Istina. The battlefield is just the same; as long as you give her suitable conditions, she can set off a storm of Arts all around, leaving the enemy inside with nowhere to run.
