Operator Overview
“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-type 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.

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.
During the course of her multiple interactions with the Ursus Student Group, Istina displayed rare communication abilities and an assured manner, and gave focused and clear answers. What is currently certain is that Istina has the intent to hold proactive exchanges with Rhodes Island, and may be a positive factor in communication with the Ursus Student Group.

Increase Trust to 50.It is now known that the "Ursus Student Self-Governing Group" was originally proposed by Istina. The union's establishment helped the Ursus students work together to 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 suitable leader. And if she can add her own input during operations, this would be even better.
When the subject of Zima was brought up, the Doctor made many pointed remarks, but Istina gave an opposing opinion. Istina believes that Zima will not become an unstable element 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 recurring student organization riots, 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 of the books coming from Lentini and Victoria during this time. With the help of these books, she learned to reevalute everything she thought she knew and began to see everything in a new light.

Increase Trust to 150.With regard to her whereabouts during the Chernobog incident, Istina modestly and succinctly declined to provide disclosure, but she showed several changes of emotion during the process. On account of Rhodes Island's current guidelines and need to protect 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 her background. Because of this, it is recommended to use psychological methods to communication 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 interest in the books in the Doctor's office, it is recommended to give her a degree of reading privileges.
