Alexandrina Sebastiane Guide & Best Builds

Welcome to our Alexandrina build guide for Zenless Zone Zero. Alexandrina Sebastiane is a useful S-Rank Electric Support Agent who provides PEN Ratio buffs. Higher PEN Ratio means all DPS Agents, especially well-built characters, will have better DMG ceilings. In our guide, we will cover everything you need to know to get the most out of your Alexandrina, from building the best Drive Discs and W-Engines, to important stat priorities and combos.

Alexandrina Sebastiane's Best W-Engines

Listed below are Alexandrina's best W-Engines. While W-Engines are listed in a priority order, what is best to build can vary slightly depending on your team composition or account funding.

Weeping Cradle
Punishment
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 increase all units' 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 the duration without refreshing the DMG increase effect. Passive effects of the same name do not stack.
Alexandrina's signature W-Engine is her best option, as this is the only S-Rank option that provides PEN Ratio. Rina's teamwide buff improves when she has more PEN Ratio herself.
Slice of Time
Say Cheese
Any squad members' Dodge Counter, EX Special Attack, Assist Attack, or Chain Attack respectively generates 20/23/26/29/32/25/28.5/32/35.5/40/30/34.5/39/43.5/48/35/40/45/50/55 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.
Alexandrina's next best option is Slice of Time. This F2P alternative is craftable at the Gadget Store, provides 4% less PEN Ratio than Weeping Cradle, and one free copy is provided via the Rookie on the Road permanent event.
Elegant Vanity and Other Alternatives
Untold Beauty
When any squad member enters the field through a Quick Assist, Chain Attack, Defensive Assist, or Evasive Assist, the equipper gains 5/5.5/6/6.5/7 Energy. This effect can trigger once every 5s. When the equipper consumes 25 or more Energy, the DMG dealt by all squad members increases by 10/11.5/13/14.5/16%, stacking up to 2 times, and lasting 20s. Repeated triggers reset the duration. Only one instance of this effect can exist in the same squad.
Given how accessible Slice of Time is, other S-Rank Support W-Engines are mostly used if you have nothing else or want to improve her personal DPS. Rina really needs PEN Ratio to shine: not having enough will make Rina seem difficult or ineffective to play.

Best Drive Discs for Alexandrina Sebastiane

Moonlight Lullaby
2-Piece Set: Energy Regen +20%
4-Piece Set: When the equipper is a Support character and uses an EX Special Attack or Ultimate, the DMG dealt by all squad members increases by 18% for 25s. Repeated triggers reset the duration. Passive effects of the same name do not stack.
Compared to Alexandrina's W-Engine options, she has various 4-Piece Drive Disc sets she can choose from. This will largely depend on who she plays with, as some of these effects do not stack.

For example, Moonlight Lullaby generally works well and is cost-effective. However, if you run 2 Supports in the same team, you may prefer to use a different 4-piece effect, such as Swing Jazz or Astral Voice.

2-Piece Recommendations include:

  • Puffer Electro
  • Swing Jazz
  • Freedom Blues or Chaos Jazz / Astral Voice / Thunder Metal
Alexandrina's best 2-piece set is Puffer Electro, as it provides an unconditional 8% PEN Ratio.

If you already have enough PEN Ratio to reach the buff cap for Core Passive: Mini Destruction Partner, you can use either Swing Jazz instead. This will further increase her Energy Regen if she is already running one of the two sets for its 4-piece effect.

If you want to improve Alexandrina's personal DPS instead, you can opt for Freedom Blues, Astral Voice, or Thunder Metal.

Swing Jazz
2-Piece Set: Energy Regen +20%
4-Piece Set: Launching a Chain Attack or Ultimate increases all squad members' DMG by 15% for 12s. Passive effects of the same name do not stack.
If the team already has another Support Agent on Moonlight Lullaby, this is a great alternative for Alexandrina to use.

2-Piece Recommendations include:

  • Puffer Electro
  • Moonlight Lullaby
  • Freedom Blues or Chaos Jazz / Astral Voice / Thunder Metal
There is not much different with the previous recommendation, as the priority is the same. Prioritize Puffer Electro if you want to reach the buff cap for Core Passive: Mini Destruction Partner more easily.
Astral Voice
2-Piece Set: ATK +10%
4-Piece Set: Whenever any squad member enters the field using a Quick Assist, all squad members gain 1 stack of Astral, up to a maximum of 3 stacks, and lasting 15s. Repeated triggers reset the duration. Each stack of Astral increases the DMG dealt by the character entering the field using a Quick Assist by 8%. Passive effects of the same name do not stack.
Freedom Blues
2-Piece Set: Anomaly Proficiency +30
4-Piece Set: When an EX Special Attack hits an enemy, reduce the target's Anomaly Buildup RES to the equipper's Attribute by 20% for 8s. This effect does not stack with others of the same attribute.
If you are running Alexandrina with Anomaly DPS Agents, or exclusively with Electric Agents, this 4-piece effect may be more useful. If you want her for more general purposes, consider other 4-piece sets first.

2-Piece Recommendations include:

  • Puffer Electro
  • Swing Jazz or Moonlight Lullaby
  • Freedom Blues or Chaos Jazz / Astral Voice / Thunder Metal
There is not much different with the previous recommendation, as the priority is the same. Prioritize Puffer Electro if you want to reach the buff cap for Core Passive: Mini Destruction Partner more easily.

Alexandrina Sebastiane's Stat Priority

Disc 4: Anomaly Proficiency
Disc 5: PEN Ratio
Disc 6: Energy Regen / ATK %
Substats: Anomaly Proficiency > ATK % > PEN > ATK

When building Alexandrina, prioritize getting 72% PEN Ratio first. This allows her Core Passive: Mini Destruction Partner to reach its buff cap. Afterwards, consider building Anomaly Proficiency, PEN, or ATK to improve her personal DPS.

Alexandrina Sebastiane's Skill Priority

Skill Priority: > > > > =

Alexandrina's most important skill to level by far is her Core skill since it decreases how much PEN Ratio you need to hit buff cap. You can prioritize her Ultimate, Special Attack, then Basic Attack next, as they help her deal more DMG. Follow up with building Assist and Dodge last.

How to Play Alexandrina Sebastiane

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.

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. While they are on the field, Drusilla and Anastella provide a PEN Ratio buff to other squad members, increasing their damage output. This is from Rina's Core Passive: Mini Destruction Partner.

You can recall Drusilla and Anastella via Basic Attack: Shoo the Fool at any time, or if they time-out. Ideally, you recall them if your DPS Agents are no longer within buff range. The Mindscape Dance Duet also extends their on-field time, allowing Alexandrina to stay off-field longer.

If you play Alexandrina in a mono Electric squad, she also passively increases the Shock duration of enemies. Thanks to Additional Ability: Banquet of Perfection, any Shocked enemies on the field will also increase all Agents' Electric DMG.

Alexandrina Sebastiane's Best Mindscapes

Alexandrina is well suited to any team composition at any Mindscape level, such as M0. Most of her strengths come from building her Core Passive: Mini Destruction Partner, W-Engine, and Drive Discs correctly.
However, players may find it more comfortable to have Dance Duet, which increases the on-field duration of Drusilla and Anastella. This Mindscape also increases the squad's Electric DMG dealt as well.

Additional Mindscape levels are also beneficial, but the next notable one is Stormy Night's Fright, which increases her support potential in an Electric focused squad. As this is a cost-heavy investment, consider investing in other Agents first.
