Faction alongside other characters such as Corin Wickes, Ellen Joe, and Von Lycaon.

A Midsummer Night's Dance: A delicate and gentle melody flows naturally through Rina's movements.

Alexandrina Sebastiane's Best Mindscapes

Rina is well suited to any team composition at any Mindscape level, such as M0, as most of her support benefits come from building her Core Passive and Equipment correctly.
However, players may find it more comfortable to play her at M1, which increases the on-field duration of Drusilla and Anastella, as well as increasing the squad buff gained as well. Additional Mindscape levels are also beneficial, but the next notable one is her M6, which increases her support potential in an Electric focused squad.

# Mindscape Description
M1 Dance Duet After being sent out to launch an attack, Drusilla and Anastella stay in place for an additional 5.5s before returning to Rina. The buff gained from Core Passive: Mini Destruction Partner by characters within 10m is increased to 130%.

How to Play Alexandrina

Alexandrina Sebastiane's gameplay primarily revolves around using her Bangboos Drusilla and Anastella to support her squad's damage capabilities by increasing their PEN Ratio.

Important: Combat Bangboos are different from Drusilla and Anastella discussed in this section. Combat Bangboos are obtained through Signal Searches on the Bangboo Channel and can level up, just like Agents and W-Engines.

When Drusilla and Anastella are on the field, they will remain in the area for a set period of time before automatically returning to Rina's side. Drusilla and Anastella's major advantage is that they can continue to execute Rina's attacks while you control another character. While they are on the field, Drusilla and Anastella also provide a PEN Ratio buff to other squad members, increasing their damage output. This is from Rina's Core Passive: Mini Destruction Partner.

If you have Rina's Mindscape Cinema 1: Dance Duet, Drusilla and Anastella can remain on-field for an additional 5.5 seconds. Rina can also manually recall them by holding Basic Attack or Special Attack while she is on the field. If there are other characters in the squad that share the same Attribute or Faction as Rina, she also passively increases the duration of Shock dealt by everyone in the squad. So long as there are Shocked enemies on the field, everyone in the squad will have an increase in Electric DMG output.

5.1.

Alexandrina and PEN Ratio

To understand how Alexandrina Sebastiane's build works, players should review how her Core Passive: Mini Destruction Partner's PEN Ratio buff cap is reached. At Lv. 1, the calculated formula* wants Rina to have a personal PEN Ratio stat of 96% at most. While not necessarily impossible to reach, it heavily reduces the freedom players may want to have with their W-Engine or Bangboo choices. As a result, if players want to use Rina effectively, they should focus on improving her Core Passive whenever feasible.

By improving Rina's Core Skill Passives and using PEN Ratio-focused Builds, players will have an easier time reaching Mini Destruction Partner's PEN Ratio buff cap of 30%. The additional PEN Ratio bonus can go up to 14.4% at Core Skill Enhancement F. The calculation only takes 25% of Rina's personal PEN Ratio into account, so players should build as much PEN Ratio on Rina to reach the Mini Destruction Partner buff cap.

Therefore, when she receives her Core Skill Enhancement F, the upgraded formula** only needs a personal PEN Ratio stat of 72% maximum, which is significantly more reasonable for players to achieve.

Keep in mind PEN and PEN Ratio are two different stats, and Mini Destruction Partner only scales off Rina's PEN Ratio stat.
While building PEN is good in general, Rina herself is a support Agent who does not have as large of a damage potential like Attack-focused Agents.
As her role suggests, she is better suited to supporting other Agents and increasing their damage potential, because her PEN Ratio buff only affects other squad members, not herself. Players should focus on reaching 72% PEN Ratio first before focusing too much on Rina's other beneficial stats.

Alexandrina's Best in Slot Guide

W-Engines Drive Discs Additional Notes
PEN Ratio Thresholds

Rina's best W-Engine is her signature Weeping Cradle, which is obtainable through any Channel banner except the Bangboo Channel. Players can also obtain this W-Engine through exchanging Residual Signals at the Signal Shop.
This W-Engine is a significant upgrade over other W-Engines currently available, as its advanced stat can provide up to 24% PEN Ratio alone, when upgraded to Lv. 60. At Lv. 7 of Mini Destruction Partner, this means that Rina only needs an additional 33.6% PEN Ratio from Drive Discs and Bangboo, in order to meet the buff cap of 30%.

In addition to helping Rina achieve her maximum potential, Weeping Cradle's Punishment Effect also increases the squad's DMG output whenever Rina attacks, with incremental bonuses the more hits she lands. The off-field effect also works, as Rina will spend most of her time off-field, while the squad benefits from the Mini Destruction Partner buff provided by Drusilla and Anastella.

While other W-Engines are also possible to slot in, they do not provide the same amount of maximum PEN Ratio that Weeping Cradle can achieve.
If players have more than enough PEN Ratio from other parts of Rina's build, they can opt to use Slice of Time instead, which provides 20% PEN Ratio at Lv. 60.
This W-Engine can be obtained for free, through the permanent Event Rookie on the Road, or through exchanging at the Gadget Store.

At the moment, no other Support speciality W-Engines can provide PEN Ratio.

Rina's best Drive Disc set is Swing Jazz, as it provides Energy Regen on top of a conditional DMG increase for the squad. Other options include Thunder Metal, if you want to improve her personal Electric DMG output.
Players are also recommended to use Puffer Electro if they require the 8% PEN Ratio 2-Piece Set bonus. However, as Rina's optimal PEN Ratio stat is quite high without investment, players should try to get as much PEN Ratio as they can from her W-Engine, Drive Disc: Partition 5, or Bangboo.

Players can also consider less optimal Drive Discs, such as Soul Rock or Proto Rock, to improve Rina's survivability in combat. However, it may be more effective to invest in a Defense-type Agent instead, such as Seth Lowell or Caesar King.

Lv. 1 Core Passive Base Formula is 25% x (Rina's PEN Ratio stat) + 6%, up to 30% total.
Lv. 7 Core Passive Upgraded Formula is 25% x (Rina's PEN Ratio stat) + 12%, up to 30% total.

Because the Skill Enhancement bonus is a percentage increase, the stat threshold requirement incrementally decreases when players continue to upgrade Rina's Core Passive.

If players do not build Rina's Core Passive at all, they will not have any base PEN Ratio to begin with. As a result, at Core Passive Lv. 1, Rina would require 96% PEN Ratio to reach the maximum squad bonus from Mini Destruction Partner.

At Core Passive Lv. 7, Rina requires a maximum of 72% PEN Ratio. Her previous Core Passives additionally provide a PEN Ratio increase, up to 14.4%. This means that theoretically, she only requires an additional 57.6% PEN Ratio from other sources. Building Rina's PEN Ratio beyond 72% is optional, as it will not further increase the PEN Ratio bonus from Mini Destruction Partner.

7.1.

Bangboo Information

Rina's best Bangboo are ButlerButler and PlugbooPlugboo. Butler is good for Victoria Housekeeping Co. focused teams, while Plugboo is beneficial if you run a squad with strong Electric Agents.

As a Support Agent, Rina is also able to make use of Bangboo with a related B Skill requirement, such as Knightboo. Knightboo is a good and easy-to-use alternative, as its ATK increase formula is based on the Bangboo's investments, not the Agents. Knightboo offers up to an additional 90 ATK (Core 1) or 160 ATK (Core 5) for 10 seconds, which is slightly better compared to other supportive Bangboo.

If players do not have an -Rank Bangboo, other -Rank considerations include ExplorebooExploreboo, ElectrobooElectroboo, and BooressureBooressure.

Alexandrina's Team Comps and Synergy

DPS Stun Support Bangboo
Koleda Belobog Alexandrina Sebastiane

For Alexandrina, Grace Howard is her most compatible DPS Agent, as Grace Howard can output a lot of Electric DMG herself, in addition to benefiting from the Shock and PEN Ratio bonuses Rina provides.
If players do not have Grace Howard, they can substitute with another Electric Agent such as Anton Ivanov.

If players decide to run Tsukishiro Yanagi instead, they may want to opt for a third Agent with a different Attribute from Electric. This is so Yanagi can benefit both from the Electric DMG buff that Rina provides, as well as the Disorder DMG from the different Attribute.

Other Attribute DPS Agents are also compatible, as every Agent can benefit from PEN Ratio buffs. However, keep in mind you may not see significant damage numbers to begin with, as their effectiveness is based on the enemy's defensive stats in addition to the Agents' personal stats. The more defense a target has, the more beneficial PEN buffs become for an Agent's damage potential. In addition, they may not benefit from the Electric DMG buffs that Rina's Additional Ability provides.

DPS Stun/Defense Support Bangboo

Grace Howard Alexandrina Sebastiane

With an Electric focused squad, players can make use of either Qingyi or Anby Demara, as both Stun Agents have their own benefits. Where Qingyi can provide damage buffs for the squad (and increases her own Damage and Daze potential when paired with an Attack Agent), Anby Demara is capable of stunning faster with enough EX Specials (and can work well in teams with either Grace Howard or Anton Ivanov).

Players can also consider Seth Lowell, as he reduces the Anomaly Buildup RES for all Attributes. Rina can also activate his Additional Ability, giving the squad some flexibility with their primary DPS Agent.

Though Tsukishiro Yanagi may be a consideration, keep in mind that Tsukishiro Yanagi will generally have a higher damage output in Disorder DMG teams. As both Rina and Tsukishiro Yanagi share the same Attribute, players may find it difficult to use another Electric Agent due to sacrificing the Disorder DMG from Tsukishiro Yanagi's kit.

8.1.

Rina and Victoria Housekeeping Co.

DPS Stun Support Bangboo
Von Lycaon Alexandrina Sebastiane

If players want a Victoria Housekeeping Co. focused team instead, they can consider either Corin Wickes or Ellen Joe as the main DPS Agent for the squad. However, keep in mind that both characters do not share the same attribute as Rina, so they will not benefit from the Shock effect that she provides in Banquet of Perfection.
As a result, it is better to use a Victoria Housekeeping Co. Stun Agent, such as Von Lycaon, along with an Electric DPS Agent, such as Grace Howard or Anton Ivanov.
