New Genshin Impact 6.5 leaks have unveiled the full details of Linnea’s signature weapon, titled Frostbound Oath, and it is shaping up to be one of the most impactful Geo-oriented weapons in the current meta. Designed to synergize with the upcoming Stygian Onslaught content, this weapon strongly enhances Geo DMG and the new Lunar-Crystallize reaction, positioning Linnea as a potential top-tier support or sub-DPS option.
According to early information from Genshin Impact Version 6.5 beta data, Frostbound Oath features high base stats and a unique passive that activates both on-field and off-field, significantly increasing its strategic value in team compositions.
Frostbound Oath Stats and Passive Effects
Rarity: 5-Star
Base ATK: 542
Secondary Stat: 88.2% Crit DMG
Passive Ability Overview
• Increases DEF by 16%.
• When the character’s Elemental Skill or Lunar-Crystallize attack hits an enemy, they gain Frost Sprite’s Reprisal for 6 seconds.
• Frost Sprite’s Reprisal increases Geo DMG by 40% and Lunar-Crystallize reaction DMG by 40%.
• While active, if a Moon Cage is nearby, all teammates gain Frost Sprite’s Prank.
• Frost Sprite’s Prank increases Geo DMG by 20% and Lunar-Crystallize reaction DMG by 20%.
• The effect lasts until Frost Sprite’s Reprisal ends and can trigger even when the character is off-field.
This combination makes Frostbound Oath extremely powerful in Geo-centric teams and potentially meta-defining for Lunar-Crystallize compositions introduced in Version 6.5.
Weapon Ascension Materials
To fully level Frostbound Oath, players will need the following materials:
• Blaze of Long Night Flint: 5 / 14 / 14 / 6
• Unknown Material: 23 / 27 / 41
• Frost-Etched Warrant: 15 / 23 / 27
• Mystic Enhancement Ore: 605
• Mora: 753,000
The total cost is significant, requiring heavy farming investment ahead of the official 6.5 release.
Why Frostbound Oath Could Redefine the Geo Meta
The weapon’s ability to provide both self-buffs and teamwide Geo amplification, combined with strong Crit DMG scaling, makes it ideal for characters who scale with DEF and benefit from reaction-based damage boosts. The off-field activation further increases its flexibility, especially in quick-swap teams.
If these values remain unchanged at launch, Frostbound Oath may become one of the strongest Geo-support weapons introduced in recent updates.
As always, since this information comes from beta sources, final numbers may change before official release.
