Soline

An Iron Burst 3 Submachine Gun DPS who aims for crit and Burst extra damage at full HP.
She is rarely a core pick for story, boss, or Raid main slots, and is almost never seen in Solo Raid teams.
Grow up!2 and My Word, My Bond!B both require full HP, so her damage drops sharply when her HP is chipped.

Every 40 accumulated normal attacks, her attack speed rises briefly. Only at full HP does she keep Critical Rate and Critical Damage on herself. Her Burst Skill deals damage to all enemies in range, and at full HP, extra damage hits the same targets once more.

Keep firing normal attacks to cycle the attack speed buff every 40 shots.
At full HP her crit holds, and her Burst deals extra damage under the same HP condition.
Keep her on auto, and dodge when HP drops to stay at full HP.

There is little evidence in the recent meta for pairings that run her in the same squad.

Cover Hit Rate with Assault Cube, and keep up sustained fire with Resilience Cube and Bastion Cube for reload and ammo. If Harmony Cube levels differ a lot, use the higher-level cube over the ranking.

Prioritize Critical Rate and Critical Damage lines to match Grow up!2's crit bonus. Hit Rate helps the SMG stay effective at close range.

Grow up!2 and My Word, My Bond!B are the core of her damage, so raise S2 and Burst. On the Ball!1 supports the 40-shot condition, so keep S1 low.

She is only occasionally mentioned as a low-tier DPS. The Burst 1 supporter Soline: Frost Ticket is a separate character.

At full HP, her Critical Rate and Critical Damage rise sharply.
At full HP, her Burst deals big extra damage to the same enemy.

Both Grow up!2 and her Burst's extra hit require full HP.
On the Ball!1 needs 40 normal attacks, so its buff applies late.
Her damage and team value are low compared to current meta DPS Nikkes.
