Alexandrina Sebastiane Best Teams and Bangboo
Rina F2P Team
Rina pairs well with Anby for a free-to-play friendly setup: they can activate each other's Core Skills and Anby's Stun/ Shock lets Rina capitalize on the Shock effect.
Simple, low-cost synergy focused on reliable CC + DPS.
Rina Anomaly Team
Rina in an Anomaly-focused team: used alongside Anomaly units to apply Shock/Disorder damage while buffing PEN Ratio to increase overall damage to enemies.
Alexandrina Sebastiane Skill Priority
Rina should prioritize both her Core Skill and Special Attack to increase the PEN Ratio buff and deal damage with her pets. Other skills take less priority as her quick-switch playstyle would not benefit from them.
| Skill | Priority | Explanation |
|---|---|---|
 core skill | Rina's Core Skill increases the PEN Ratio buff, which is her main source of Support. | |
 special attack | You will be using Rina's Special Attack as your main DMG source, so upgrade this alongside her Core Skill. | |
 chain attack | Rina's Chain Attack should be prioritized last for a decent DMG and Daze increase. | |
 basic attack | Rina's Basic Attacks are not necessary to upgrade since she'll mostly be off the field. | |
 dodge | Once again, due to her low field time, you don't need to level up Rina's Dodge. | |
 assist | Rina's Assist Skill allows her to deal some Daze, but it's less of a priority than her other Skills. |
