Should You Pull?SITUATIONAL

Rina is a specialized support essential for enabling Electric teams through reliable PEN Ratio buffs. She is highly recommended if you main Electric DPS characters but can be skipped if your account focus lies elsewhere.

Rina commands her two puppets, Drusilla and Anastella, to execute ranged attacks that manipulate the field while she remains at a safe distance. Her primary utility stems from her Core Passive, which significantly boosts the squad's PEN Ratio based on her own stats. By managing puppet deployment, she maintains consistent offensive pressure and buffs the team without needing to stay constantly active on the field.

Weeping Cradle

Energy Regen

While off-field, Energy Regen increases by 0.6/0.75/0.9/1.05/1.2 per second. Attacks from the equipper enhance the squad's 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 its duration without refreshing the DMG increase effect. Passive effects of the same name do not stack.

Why it works —Weeping Cradle is the premier choice, offering massive Energy Regen and stacking squad DMG buffs.

Kaboom the Cannon

Energy Regen

When any friendly unit in the squad attacks and hits an enemy, all friendly units' ATK increases by 2.5/2.8/3.2/3.6/4% for 8s, stacking up to 4 times. The duration of each stack is calculated separately, and each friendly unit can provide 1 stack of the buff. Passive effects of the same name do not stack.

Why it works —Kaboom the Cannon offers decent team-wide ATK buffs but is less specialized for Rina's needs.

Any squad members' Dodge Counter, EX Special Attack, Assist Attack, or Chain Attack respectively generates 20/23/26/29/32 (Dodge) | 25/28.5/32/35.5/40 (Special) | 30/34.5/39/43.5/48 (Assist) | 35/40/45/50/55 (Chain) 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.

Why it works —Slice of Time is the best F2P option, providing consistent Energy generation via various combat actions.
