Moonlight Lullaby 4pc keeps a nearly 100% uptime DMG buff, paired with 
Swing Jazz 2pc for energy.
Astral Voice 4pc buffs strongly for teams that use Quick Assist a lot—a flexible alternative.4: ATK% · 5: PEN Ratio · 6: Energy Regen (swap to ATK% if you have enough energy)
PEN > ATK% > Energy Regen > flat ATK
Skill priority: Core Skill = Special Attack first (boosts the PEN buff), Assist/Basic later
Rina is still a reliable PEN Ratio buffer for any DEF-penetration team, especially Electric carries. But newer supports (
Astra Yao, 
Lucia) have surpassed her in total buffing, so only prioritize her if your team needs PEN. Great to use if you already have her; if not, don't force the pull.
Endgame targets (per game8/mistermenplays): ATK 2,200+ / HP 10,000+ / DEF 800+ / Anomaly Proficiency 220+ / PEN Ratio 40%+. KEY THRESHOLD: aim for ~72% PEN Ratio so the team receives the full 30% Core buff cap (Passive 6) — below that it scales down (buff = 25% of Rina's PEN Ratio + a flat amount, capped at 30%). Main stats: slot 4 ATK% · slot 5 PEN Ratio · slot 6 Energy Regen. Substat priority (per game8): Anomaly Proficiency > ATK% > PEN Ratio = flat ATK. As a buffer, having enough energy to cycle EX Special matters more than raw ATK.
1) OPENER: swap Rina in, press EX Special (when energy allows) to send Drusilla & Anastella at the enemy — the moment the pets strike, the whole team gains the PEN Ratio buff. 2) SWAP TO CARRY: immediately switch to your DPS/Stunner (Harumasa, Soldier 0 Anby, Qingyi...); the pets keep attacking off-field, holding the PEN buff while the carry bursts. 3) LOOP: when the pets return to Rina (M1 adds 5.5s), swap back and re-press EX Special / Basic to redeploy them. 4) ULT / CHAIN: fire when the group ult is ready to refresh buffs and pile on more Shock. 5) ELECTRIC TEAMS: Rina's Additional Ability extends Shock from 10s to 13s → keep at least one Shock applier active to bank the ~30% bonus damage.
After being sent to attack, Drusilla & Anastella linger 5.5s longer before returning to Rina; the Core (Mini Destruction Partner) PEN Ratio buff to allies within 10m is raised to 130% of its value. This is her BEST mindscape as a support: longer pet uptime means near-continuous PEN buff and fewer swaps back to redeploy. Prydwen calls M1 a 'big QOL upgrade'. If an F2P has spares, stop here.
On entering combat / swapping in, Rina's own DMG +15% for 12s (once per 18s). It's a PERSONAL damage buff, but Rina sits off-field as a PEN buffer almost the whole fight, so her personal damage rarely matters — low value for a pure support role.
Basic / Assist / Dodge / Special / Chain Attack +2 levels. A small flat bump with no gameplay change; just a stepping stone toward M4/M6.
While both Drusilla and Anastella are deployed, Rina's Energy Regen +0.5/s. Only slightly speeds up EX Special / rotation cadence — a very minor sustain gain, not worth pulling for on its own.
All skills +2 levels again. Still just flat numbers, a bridge to M6 — low value.
When an EX Special / Chain Attack / Ultimate hits an enemy, the WHOLE squad gains +15% Electric DMG for 8s. A genuine team buff that adds straight to an Electric carry's output — her strongest mindscape and the only real reason to chase M6. Whale-tier; most players stop at M0/M1.
- Rare PEN Ratio buffer: grants the whole team 25% of Rina's PEN Ratio + a flat amount, capped at 30% — raw armor penetration that suits any carry losing damage to enemy DEF (especially Electric carries).
- Nearly hands-free off-field buffing: just deploy the pets and swap, taking no field time from the carry — a simple rotation that's beginner-friendly.
- Extends Shock for Electric teams: her Additional Ability raises Shock duration from 10s to 13s → higher uptime and roughly 30% more total Electric anomaly damage.
- High movement speed makes it easy to reposition the pets around enemies — light execution, few mistakes.
- Rina herself is PEN-Ratio-hungry: below ~72% PEN her team buff falls short of the 30% cap, so an under-PEN Rina feels weak and awkward to play — demanding disc RNG and farming.
- Slow skill animations: her Special/EX inputs are sluggish, easy to fumble timing if you rush the rotation.
- Power-crept by 3.0: newer supports (Astra Yao, Lucia) out-buff her overall; only prioritize Rina when a team genuinely needs PEN Ratio — don't chase her otherwise.
Fits Shiyu Defense when paired with armor-piercing Electric carries: the PEN Ratio buff lets Harumasa / Soldier 0 Anby burst inside Qingyi's stun window. Rina scores nothing herself but raises the whole team's damage ceiling. In 3.0 she's a 'solid' rather than 'top' support — pick her when the team needs DEF penetration; with Astra Yao available you'll usually prefer Astra.
Also usable in Deadly Assault with Electric/Shock teams: PEN Ratio plus the 13s Shock extension helps stack anomaly on multiple high-HP foes and keeps output steady across long stages. Not a highlight like a carry, but a dependable buff floor when bosses have high DEF.
