Release1.0

Alexandrina "Rina" Sebastiane is an Electric Support who fights through her two Bangboo, Drusilla and Anastella. While they're deployed, the whole squad gets up to +30% PEN Ratio, and her Awakened Potential adds up to +576 ATK and +468 DEF on top. Two years after release, this standard S-Rank is still a top-tier Support, and the go-to partner for DEF-scaling Armorers like Claret.

PEN Ratio Support

W-Engines

Weeping Cradle BiS

S · PEN Ratio

Her signature, and the only S-Rank Support W-Engine with a PEN Ratio main stat: it's what lets her reach 72%. It also amplifies all damage on the target, and her Bangboo's constant attacks keep that effect refreshed.

Off-field Energy Regen +0.6/s; the wielder's hits make the target take 10% to 20.2% more DMG from all units for 3s.

Kaboom the Cannon

A · Energy Regen

Great A-Rank: Drusilla and Anastella count as allies for its stacks, so she keeps the ATK buff up almost alone. Energy Regen main stat instead of PEN Ratio, though.

Each squad member landing a hit grants the whole squad ATK +2.5% for 8s, up to 4 stacks.

Slice of Time

A · PEN Ratio

Craftable F2P pick with a PEN Ratio main stat (4% less than Weeping Cradle): the easiest way to get close to the buff cap. Icy Veins's second choice.

Squad Dodge Counters, EX Specials, Assist Attacks and Chain Attacks generate bonus Decibels and Energy for the wielder.

Elegant Vanity

S · ATK%

Astra Yao's signature adds a squad DMG buff, but no PEN Ratio: only if you have nothing better.

Gains 5 Energy when an agent enters via Quick Assist, Chain Attack, Defensive or Evasive Assist; spending 25+ Energy gives the squad +10% DMG for 20s, up to 2 stacks.

Unfettered Game Ball

A · Energy Regen

Squad CRIT Rate after Attribute Counters. Game8 ranks it second, but it only comes from the City Fund.

Attribute Counter effects raise all units' CRIT Rate against the target by 12% for 12s.

Drive Discs

Moonlight Lullaby ×4

Puffer Electro ×2

Best set for Supports: +18% squad DMG for 25s from an EX Special or Ultimate. Puffer Electro's +8% PEN Ratio is the best 2-pc by far.

Set effects

2pEnergy Regen +20%

4pWhen 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.

If another Support in the team already runs Moonlight Lullaby (it doesn't stack).

For Electric Anomaly teams (Yanagi, Grace): her EX Special lowers the target's Electric Anomaly Buildup RES.

Set effects

Dodge

Level her Core Passive first: its A/C/E nodes give 14.4% PEN Ratio and raise the flat part of the buff to +12%. Without Weeping Cradle you'll land around 68% PEN Ratio, i.e. a 29% buff: still very good.

Teams

Recommended teams

Armorer: Claret & Koleda

Claret

Koleda

Rina

Rina's most used team, and the ninth most used team in the current Deadly Assault (6.4%). Her flat DEF buff feeds Claret's DEF scaling, and Koleda's Additional Ability works with Armorers. Norma is an equally popular Stunner here. Bangboo: Ultra Jake (Claret is from Roscaelifer).

Armorer: Claret & Norma

Claret

Norma

Rina

Claret's best team, and Game8's pick for Rina. Norma's buffs suit Armorers and her extra Chain Attacks help with Decibels. Rina shares Claret's attribute, so her Additional Ability is active. Bangboo: Ultra Jake.

Sigrid & Dialyn

Sigrid

Dialyn

Rina

Sigrid is saturated on most buffs, so Rina's PEN Ratio is especially valuable. For a standard-only version, play Lycaon instead of Dialyn: he shares Rina's faction and activates her Additional Ability. Bangboo: Ultra Jake (Sigrid is from Roscaelifer), or Butler with Lycaon.

Guide

How to play

Her buff

Most of her attacks send Drusilla and Anastella out. While at least one of them is deployed, the rest of the squad gains PEN Ratio equal to 25% of Rina's PEN Ratio + 12% (max 30%).
Her Awakened Potential also gives the squad 8 ATK and 6.5 DEF per 1% of Rina's PEN Ratio (max 576 ATK / 468 DEF) while that buff is active.
Both caps are reached at 72% PEN Ratio, which is why she builds PEN Ratio above all else.

Keeping the Bangboo out

The Bangboo normally return after 5.5s. EX Special, Chain Attack and Ultimate put Rina in the Spotless state for 13s: the Bangboo attack on their own every 2.5s (Morning Cleanup), which resets their timer, and every 6 stacks of Fright upgrade the next one to Midnight Cleanup.
Her Dash Attack is a fast way to deploy them outside of Spotless.
Avoid her hold Basic Attack (Shoo the Fool): it recalls the Bangboo and ends the buff.

Rotation

Out of Stun, keep the Bangboo out with Basic Attacks, Dash Attacks or an occasional EX Special.
Right before the Stun, use her EX Special or Ultimate: Spotless (13s) plus the 5.5s exit timer cover almost the whole Stun, and Moonlight Lullaby triggers at the same time.
Swap out: she doesn't need field time.

Her Additional Ability (same Attribute or Faction) extends Shock by 3s and gives +10% Electric DMG while an enemy is Shocked. Nice in Electric teams, but not required.

Strengths

Standard S-Rank that's easy to get, with a strong buff for almost every Attacker, Anomaly Agent and Armorer.
PEN Ratio is rarely saturated, unlike DMG% and CRIT DMG buffs.
Her flat DEF buff, rare among Supports, makes her a perfect match for DEF-scaling Armorers.
Very little field time, and her Bangboo trigger team W-Engine effects like Kaboom the Cannon on their own.

Weaknesses

Needs a lot of PEN Ratio (72%) to max her buff, which makes her signature W-Engine important.
Still wants M1 to keep her Bangboo out comfortably.
Anti-synergy with DEF Shred (Nicole, Trigger's signature...), and her PEN Ratio buff does nothing for Rupture Agents' Sheer DMG.

Notable dupes · Mindscape Cinema

Big upgrade

Drusilla and Anastella stay 5.5s longer, and allies within 10m get 130% of the Core Passive buff. Her most important Mindscape by far.

Optional

+15% DMG for Rina herself when she switches in.

Optional

+0.5 Energy/s while both Bangboo are deployed.

Solid upgrade

EX Special, Chain Attack and Ultimate hits give the squad +15% Electric DMG for 8s: great in Electric teams only.
