Introduction to guide

In this guide, I will go over all things Rina besides trust/ trust events, so I will go over her kit with additional info, optimal play, what cinema's you want on her, what skills to prioritise enhancing, her best disks, w-engines and teams.
I won't go into spoiling Rina's lore or trust I think that is something you should get to experience yourself however I will try to convince you why you should play her/ invest in her, she is the ultimate filler agent that can be the perfect third agent and nothing does a better job explaining why than my first point.
WARNING HER KIT IS NOT A COPY AND PASTE OF ZENS DESCRIPTION I DESCRIBED THE ABILITIES AND WENT INTO THE ACTUAL USE OF HER KIT.

Rina's kit
core passive
Now, let's start with tips and her kit off with the most important part of Rina's kit, her core passive. When Rina attacks you will deploy Drusilla and Anastella if it is a basic attack this will deploy them for roughly seven seconds if it is a chain or special attack it will be for roughly nine seconds when Drusilla and Anastella are deployed other squad members are given 25% of Rina's pen ratio+ 7.5%-12%, depending on the level, up to 30% pen. To reach the 30% cap, Rina's core passive needs to be maxed out and Rina needs to have at least 72% pen. The easiest way to tell the passive is active is Drusilla and Anastella will not be beside Rina as well, and when you play another agent, there will be an icon at the top of the screen.
Additional info
To just put in perspective how insane the passive is Nicole's max defence reduction is 40% for 3.5 seconds, it is harder to proc and lasts less time additionally any unit can have or build pen so you are just adding 30% never mind what you already have on them.
Additional ability
Rina's additional ability increases the duration of shock by 3 seconds and increases electric damage when a shocked enemy is on the field.

Rina's basic

Rina's basic attack is a four-part attack, the first two being physical and the third and fourth being electric, you can also use an EX and be where you left off in the chain. You can also choose to hold her basic attack to do a close AOE lighting attack, however this doesn't deploy Drusilla and Anastella.
Additional info
The best time to use her charged basic attack is to charge it when a boss is about to go into phase two so it goes off when they do, then instantly follow up with an EX and swap agent.

Rina's dodge

The normal dodge attack does physical damage and the counter dodge attack does electric damage, however, what the game doesn't tell you is that both of these count as your first attack in a chain, meaning you can do electric-physical-electric-electric.
Additional info
This could be wrong but at least through my testing Rina's dodge is faster than Ellen's sprint, so Rina is my go-to in missions where you have to pick up coins or destroy boxes as the objective
Rina's assist

The assist doesn't have much going for it, other than it is a good way to hit multiple enemies at once and that it is electric damage.
- - - - - - - - - - - -
Rina's special attack


The special attack does a single line that bounces doing low electric damage while the EX special attack is a line of a lightning storm, these are Rina's bread and butter and will be the thing you use the most on her, it has her highest daze multiplier on any of her attacks and is her best damage option with most teams. The normal special attack does still serve a purpose, meanly to keep your core passive up.
- - - - - - - - - - - -
Rina's chain

Rina's chain attack is a massive electric ball that pushes enemies and a lot of the time will group small enemies with good positioning, the chain will deploy Drusilla and Anastella on use if it is a 1 chain it will lead to an assist attack and I tend to use it first especially if it is a two or three chain.
- - - - - - - - - - - -
Rina's ultimate

Rina's ultimate is her chain attack on a bigger scale with more damage with the added benefit that other agents gain 10 energy and the next agent gains 20 additional energy. Sadly, it's just better to use your DPS's ultimate unless you are running an anomaly team.

Optimal gameplay
With that out of the way, optimal gameplay sadly is all about never having Rina on the field and when she has to be her being on it for as short amount of time as possible her job is to throw out a special or basic attack to activate the core passive and then be swapped out straight away being took out again to reactivate the passive your goal is to try and have the passive up as much as possible. On the bright side, she will not compete with your other agents for field time.

Above is an example of a Rina fast swap where I swap to her and attack and swap off to deploy, this can be done with her special or basic attack at the same speed, however through my testing it seems you need a full team.

Cinema
Rina has 3 main cinemas that you will want, luckily her M1 is the best her M4 is just nice to have and her and M6 is team comp pacific, so let's get into them.
- M1 makes Drusilla and Anastella stay deployed for an additional 5.5 seconds this is huge and makes her have to be out even less than she has to be, but it does get better it also increases the core passive pen value by 130% if your agent is 10ms within Drusilla and Anastella.
- M4 increases Rina's energy regen by 0.5/s when Drusilla and Anastella are deployed it is nice and lets you use your EX special more, but it is nothing to write home about.
- M6 luckily or unluckily depending on who you are is team comp dependent whenever you hit an EX special, chain attack or ultimate electric damage is increased by 15% for 8 seconds so it is only excellent if you are running an electric comp.

Skill Priorities
Core passive - Special Attack - Chain Attack - Basic Attack - Assist - Dodge
The reason it is in this order is that they are what you will be using the most on Rina.
Best Disks
Rina has a lot of disc options and none are the wrong answer, it completely depends on what team you have her in, so I will run through them. However, all of them want Anomaly Proficiency on slot 4, pen on slot 5 and energy regen on slot 6 with pen and anomaly mastery as sub stats due to damage not being a focus on Rina.
Anomaly teams


Anomaly teams want to run 4 freedom blues for the increased 30 anomaly proficiency and reduced anomaly build up from EX specials, and 2 swing jazz for the 20% energy regen. This will allow you to proc anomaly more often
Electric teams


Electric teams want to run 4 freedom blues for the increased 30 anomaly proficiency and reduced anomaly build up from EX specials, and 2 Thunder metal just to increase Rina's damage a bit. This will allow you to proc shock more often, especially since your whole team is electric.
Mixed team


A mixed team is anyone who isn't electric or anomaly for this you want to 4 swing Jazz this is mainly for the 4 piece bonus that makes it that when launch an ultimate but more importantly a chain attack you increase the team's damage by 15% for 12 seconds you also run 2 puffer electro as it gives 8% pen.

W-Engines
Rina has two excellent W-Engines, the best being weeping cradle
it gives 684 attack and 24% pen when level 60 with its passive being
"While off-field, the equipper's Energy Regen increases by 0.6/0.75/0.9/1.05/1.2/s. Attacks from the equipper enhance the squad's DMG against a struck target by 10%/12.5%/15%/17.5%/20% for 3 seconds. During this period, this effect
is further increased by 1.7%/2%/2.5%/3%/3.3% every 0.5s, up to a maximum additional increase of 10.2%/12%/15%/18%/19.8%. Repeated triggers only refresh its duration without refreshing the DMG increase effect. Passive
effects of the same name do not stack"
The reason weeping cradle is so good is that it offers so much value from one single W-engine Rina gets more energy to use her EX more, gives everyone a short damage buff but due to Rina's EX and chain staying on the field for afew seconds before it finishes it's actually longer than a 3-second buff, and it gives pen the only con it has is that its S rank, but it easily deserves it.
The second best being slice of time
it gives 594 attack and 20% pen when level 60 with its passive being
"Any squad members' Dodge Counter, EX Special Attack, Assist Attack, or Chain Attack respectively generates 20/23/26/29/32 (Dodge) | 25/28.5/32/35.5/40 (Special) | 30/34.5/39/43.5/48 (Assist) | 35/40/45/50/55 (Chain) more Decibels and generates 0.7/0.8/0.9/1/1.1 Energy for the equipper. This effect can trigger once every 12s. The cooldown for each type of attack is independent of others. Passive effects of the same name do not stack."
This is a worse weeping cradle in my eyes, but as an A rank it is still very good, you get more pen for Rina get energy for her every 12 seconds and get Decibels to fill up your ultimate meter faster for doing things you would be doing anyway.

Teams
lastly, we have 3 teams you play Rina the same way in all of them be that optimal or how you want to play, the teams follow the same structure as the disks being an anomaly team, electric team then mixed team.
Anomaly team

The goal of the anomaly team is to proc shock, with grace and Rina while you keep Drusilla and Anastella deployed, then swap over to piper to proc assault on the same enemy while they are still shocked to proc disorder.
The best bangboo to run is plugboo and if you dont have it then electroboo.
Electric team

This is the most free to play team and Anton can also be swapped out for Grace, your goal is to keep Drusilla and Anastella deployed, stun with Anby then burst with Anton all while getting those sweet shock procs.
The best bangboo to run is plugboo and if you dont have it then electroboo.
Mixed team

As I said, Rina is the ultimate filler the mixed team is anyone who can go in slot 1 and 2 who will work well together or someone who works well with Rina paired with someone else this could be something like Grace, Koleda and Rina or Ellen, Lycaon and Rina really whatever you want it to be as long as it has some form of synergy or your having fun.
The bangboo here depends on the other agents eg for Grace, Koleda and Rina you could use safety or plugboo. Whereas it would be sharkboo if it was something like Ellen, Lycaon and Rina.
Thank you for reading
That's finally it from me, thanks for reading and just remember Reni loves pen and you should invest now.
