In S1, the Frost rushdown lineup built around Hvitar was often seen at the top of the Grand Gladiator Arena rankings, thanks to its few counters and flexible composition. Here is a brief guide to the lineup strategy for your reference.This lineup is centered around Hvitar, whose ultimate skill deals high damage to all targets. She works best with same-school teammates who inflict Frost on enemies to increase her ultimate skill damage, along with support heroes who create a safe environment for her to deal damage. In most battles, Hvitar can ensure the win simply by casting her ultimate skill.Summary: Stack as much Skill Haste as possible on Dorkuraz. With his battle skill that recharges his Ultimate Energy, Dorkuraz can cast his ultimate skill first and trigger the Puppeteer Revelation set effect to boost same-element allies' Ultimate Energy. Rava, equipped with the Holy Hunter set and Witch's Remains, can inflict Frost, Defense Penalty, and control effects on a wide range of enemies. This makes it easier for Hvitar's ultimate skill to directly cause casualties. When facing a similar lineup, killing the enemy Hvitar first gives you the upper hand. In this case, you can replace Estella with a secondary damage dealer like Auster or Rowena to further increase the team's first-round burst damage. Eurion can also be substituted flexibly depending on the enemy lineup. (E.g., Against control lineups, it is recommended to use Lucien; against high-burst heroes like Nastjenka, it is recommended to use Berengar.)
 Summary: Activate the Tactical Advance talent for Lucien and primarily stack HP and Skill Haste. Have him wear the Puppeteer Revelation set to recharge allies' Ultimate Energy. Lucien can also grant a shield with Control Immunity and Ultimate Down to all allies at the start of battle, allowing Hvitar to cast her ultimate skill without interruption. Both Elecebre and Lossenia should use the Holy Hunter set to frequently inflict control effects and slow down the enemy's offense. It is recommended to adjust equipment to make Felosia the lowest-HP member on your team, so Hvitar won't be the primary target when facing dive heroes like Nastjenka. Elecebre or Felosia can also be replaced with a secondary damage dealer like Auster to further enhance the lineup's burst damage.
