Botzu's Quick Evaluation
+ Talent: When deployed, all ally Caster SP gain increased (does not stack with similar effects)
+ Decreases movement speed of enemies within attack range
+ S2 and S3: Extremely powerful crowd control
+ S2: Great synergy with powerful attackers (especially with limited range) as you can hold enemies within their range.
+ A well rounded AOE caster that can provide both damage and utility.
= While the damage on her skills is high when active, she plays more of a crowd control role than DPS
- Long Skill cooldowns with low up-times (somewhat mitigated by her SP gain Talent)

Operator Overview
Not much is known about Mostima. She keeps a smile on her face and an arm’s-length of distance between her and the rest of the world. Pleasant yet emotionless, Mostima seems to have no objection to acting as a 6★ AoE Caster for Rhodes Island, one who also wields aspects of Support and Crowd-Control.
Mostima manipulates time to sloooooow down her enemies while speeding up the SP generation of her Caster allies. Her first Talent enables the SP recovery, while her second Talent (obtained upon promotion to E2) does the Slowing. Her Skills are the real key to her success, as Skill 2 slams a potent Stun on all enemies in range and deals damage to them every second while they’re stopped in their tracks. Yet her Skill 3 has an even greater range of effects: Mostima’s attack range and ATK increase, she hits all enemies in range, the strength of her passive Slow increases, and her attacks push all targets away from her. It takes a special enemy indeed to make it past Mostima while her Skills are active.
That being said, there is a lot of time where Mostima’s Skills will not be active, as they have very high SP costs (especially her Skill 3!) and neither Skill is active for very long (especially her Skill 2), meaning neither has very high up-time. In addition, Mostima suffers from the usual downsides of AoE Casters, including high DP cost and slow ASPD. Her SP generation and crowd control are useful utilities even while her Skills are on cooldown, though, making Mostima a timely addition to any Doctor’s repertoire.
Elite Promotion Discussion
-
3rd Skill - Key of Chronology - Do you need all those enemies to just chill out? To take a breath, tone down the anger and violence, and just be eliminated in a calm, peaceful, and orderly manner? Mostima makes it happen with her laid back attitude and amazing wide Area of Effect crowd-control. Her S3 Slows all enemies by at least 45% in an increased Range, while also making them step-off with a light pushback. To top it off, it hits all enemies in range and buffs an already good ATK stat. The duration is decent, but the cooldown is quite long, so judicious use will be required, but this is one of the best tools out there to make those enemies chillax and feel the buena onda.
-
Talent 2 - Subjective Time Dilation - A passive movement speed Slow of enemies within her attack range by 15%, which is a huge boost to her utility and functioning as a crowd control Operator. As is obvious, it combines with her S3 to provide a powerful wide range Area of Effect Slow.
-
Talent 1 Upgrade - Skill Aura - Caster - Doubles the SP Recovery rate that she provides to all Caster Operators. Another great boost to her overall utility, and an important buff for Caster teams and herself as well because of the large SP Costs of her Skills.
Skill Mastery Suggestions
-
S2M2 - Increases the Stun by an extra second, so it’s worth a look if you use this Skill.

Increase Trust to 50.A transporter who always wears a smile on her face.
She is well-informed and well-traveled, having a good understanding of the geography and customs of most countries in Terra. She often drops facts about various places that would be considered secrets to outsiders. However, tracking her down can be as hard as chasing a ghost, and no one seems to be able to find her when she's needed.
She can get along with just about everyone, but also seems to keep her distance at the same time.

Increase Trust to 100.Many consider Ms. Mostima to be a black box.
First of all, just being able to find her is no small feat.
Second, even if they manage to talk to her, some say that they feel as if they are talking to the air. Regardless of if they're thanking her, admiring her, swearing at her, or piling hatred upon her, she seems to only respond by curling the corners of her lips into a wry smile, answering with a normal demeanor as if she felt no emotions.
And Ms. Mostima herself made it clear that regarding emotions, she "doesn't hate them, but has no need for them." Her words reflect a remarkable nonchalance. This is an important reason why many consider her to be more terrifying than even less personable colleagues. Whether her personality is a result of her past, or simply a numbness derived from many long years of work as a transporter, we may perhaps never know.

Increase Trust to 150.As a veteran transporter, Ms. Mostima often has some logistics commissions that require her to go to remote or even dangerous places, so she will often not be aboard the Rhodes Island ship - terms that have been specified in her onboarding contract.
In fact, very few Operators are actually standing by on the ship at all times. Once the Rhodes Island ship has docked at a certain location, Operators are free to carry out activities in the locale as long as they maintain contact with the ship and do not act in a way that would damage the interests of Rhodes Island.
Beyond this point, however, Ms. Mostima also has a few peculiarities. According to the application she submitted, Ms. Mostima often proactively seeks out delivery orders that would require her to travel abroad. Usually, Rhodes Island couriers will only operate in a local vicinity, because the time and risk involved in long-distance travel is a serious consideration for even the most experienced in the industry. Yet it doesn't seem to conern Ms.Mostima.
Does this mean that she has a special reason for doing so?

Increase Trust to 200.According to the resume submitted by Ms. Mostima, she worked as a transporter throughout all of Terra, but mentioned nothing else beyond that.
Why would she provide her services for Penguin Logistics, why did she already know Ms. Exusiai, and most importantly, why did she become a fallen angel? Even though Ms. Mostima seems to have integrated well into Rhodes Island and has even established trust with the Doctor, she is still a complete mystery in the eyes of many.
Following the guideline that, outside of extraordinary situations, we are not to pry excessively into the history of our Operators, Rhodes Island has no plans to seek answers to each and every one of these questions. However, one truth is very clear.
The Law is absolute. From the moment she aimed her gun at another of her kind, her fate was already decided.
This is a publicly known secret.

Promotion Record
Upgrade to Elite LV2.In addition to her past experience, there is another noteworthy thing about Ms. Mostima, and that is her ability. Her two staves, known as "Black Lock" and "White Key" respectively, can cast very different spells. This is an extremely rare phenomenon, and her explanation of this is preliminary at best.
There is no doubt that Ms. Mostima's powers are unfathomable. According to the judgment of Chief Engineer Kal'tsit at the time she tested Ms. Mostima's abilities, Rhodes Island's training facilities would have been destroyed if she had put more effort into the testing. Such is the terrifying scale of her power.
More importantly, though, what was the monstrosity that appeared behind her at the moment the two forces within her hands overlapped?

| Appointed as Assistant | Ahaha, aren't you the lucky one, Doctor? I don't have any work for the day, so I wouldn't mind keeping you company for a bit. |
|---|---|
| Talk 1 | The marketplaces of Lungmen, the suburbs of Ursus, the ancient ruins of Victoria… Doctor, this world holds countless beautiful sights, but very few people will ever seek them out. |
| Talk 2 | Doctor, do you want to hear a story of my journeys? In that case, I'd recommend preparing some fine tea cakes before we sit down. Otherwise, even the most fascinating tales will turn bland. |
| Talk 3 | I've witnessed the rise and fall of many organizations, but so far, Rhodes Island is the most interesting one I've seen. Will the epochs bend to your will, or finally swallow you whole? …I'm dying to find out. |
| Talk after Promotion 1 | Doctor, concerning our next destination, I have a few recommendations for where we can get some good food. Interested? |
| Talk after Promotion 2 | Doctor, you seem to already know a thing or two about fallen angels. Unfortunately, I can't give you any more details than that. Even if I could share everything else with you one day, this would remain my solitary secret. |
| Talk after Trust Increase 1 | Doctor, you don't need to concern yourself with how to have a good relationship with me. For me, friends, family, and love… I have nothing against them, but I don't need them either. Heh, not like that's going to stop you from trying, right? Well, I don't really mind, so give it your best shot~ |
| Talk after Trust Increase 2 | I'm back… Huh? No way, Doctor, were you seriously waiting here for me the whole time? You even brought snacks… Hah, all right. If you're going to go this far, I guess I can't turn you down. As thanks, I'll tell you about something interesting that happened on a delivery run. |
| Talk after Trust Increase 3 | …I see now. When I thought of having a friend like you, the spark of joy I felt wasn't fake after all. Scrap what I said before, Doctor. Maybe I do need a bit of warmth in my life. |
| Idle | Hehe… Sweet dreams, Doctor. |
| Onboard | Hey there, Doctor. You might've heard from Emperor that I'm not bound by the contract between Penguin Logistics and Rhodes Island, and can therefore act independently. Having that said, I'll probably be staying here anyway when I'm not busy, so I'll see you around~ |
| Watching Battle Record | Let me see how Rhodes Island fights. |
| Promotion 1 | Doctor, relying on me isn't a very wise decision. |
| Promotion 2 | Doctor, you really want to see me go all out? Just for the record, I'd like to ask - I won't have to worry about paying for the collateral damage after this, right? |
| Added to Squad | Okay~ |
| Appointed as Squad Leader | Hmm... Sorry, but why don't we let everyone do their own thing? |
| Depart | If this is the place… I'll lead the way. |
| Begin Operation | Let's get this started. |
| Selecting Operator 1 | Hm? |
| Selecting Operator 2 | Heheh… |
| Deployment 1 | Nice weather out here. |
| Deployment 2 | Not a bad view. |
| In Battle 1 | Seventy percent-ish should do the trick. |
| In Battle 2 | Isn't it about time to wrap things up? |
| In Battle 3 | I have nothing against you guys, but this is just a part of life. |
| In Battle 4 | What should we get to eat after this? |
| 4-star Result | Some thrill-seeking every now and then isn't half bad either. |
| 3-star Result | Hm? I thought I missed a few, but I guess that's a job well done. |
| Sub 3-star Result | For a transporter, the results of a battle don't really matter. Just surviving is enough of a victory. |
| Operation Failure | I guess I don't get this whole "teamwork" thing after all... |
| Assigned to Facility | Mind if I go wander around? |
| Tap | Huh? |
| Trust Tap | Let's have a chat, Doctor. |
| Title | Arknights. |
| Greeting | How's your day going, Doctor? |
