Fina Tier / Rating

Playable	Combat Partner

Lumino Buffer Specialist

Fina excels at enhancing her team’s combat potential through her abilities. She uses skills like Boisterous Tea Party to boost allies’ PEN stats and Taleweaver Quill stacks to increase her Skill Damage and Skill Range.

Ideal for Team‑Boosting Roles

Fina is most effective in longer battles or missions where she has time to accumulate stacks and maintain her buff window, making her ideal for supporting primary DPS characters in both PvE and Co-op.

Immersive Theatre Guide & How To Beat

Fina Best Weapon

Fina's Best Melee Weapon

Best Melee Weapon
Remanent Reminiscence

Fina is a Support who provides buffs and debuffs from her Skill and Ultimate. Increasing Fina's Sanity recovery helps maintain her Ultimate uptime.

Fina's Best Ranged Weapon

Best Range Weapon
Dreamweaver's Feather

Fina is best used with her signature weapon, Dreamweaver's Feather to buff teammates' ATK. Arclight Apocalypse can also be used, but its team buffs are RNG-based. Both weapons increase her Skill Range so her buffs and effects have a wider range.

Fina's Best Partner Weapon

Best Range Weapon
Dreamweaver's Feather

As a Combat Partner, Fina is best used in combination with her signature, Dreamweaver's Feather, a weapon that can both increase her Skill Range and buff allies.

Fina Best Demon Wedge

Loadout Details

Character Demon Wedge Set
Prime ∙ Serenity	Skylume ∙ Midnight Sun	Vigilant	Wings ∙ Inspo	Eternity ∙ Abnegation
Nirvana ∙ Volition	Nirvana ∙ Volition	Vigilant	Wings ∙ Shards	Inspo

Our Demon Wedge set focuses on the ability to use Fina's buffs consistently by maximizing her Sanity while also increasing her Skill DMG.

Note that Eternity ∙ Abnegation's negative Skill Range can be offset with a max smelted Dreamweaver's Feather. Swap it out with a regular Eternity if you don't already have that weapon.

Melee Weapon Demon Wedge Set

Our weapon of choice, Remanent Reminiscence, is included in the build as a cheap way to recover extra Sanity. While you would normally use Fina with a ranged weapon such as Dreamweaver's Feather, Osteobreaker, or Screamshot, you can viable use Remanent Reminiscence or even Tetherlash.

Range Weapon Demon Wedge Set
Impetus	Foldover	Penetration	Rage ∙ Trammel
Celerity	Impetus ∙ Focus	Faction Hunt	Free Slot

Dreamweaver's Feather is Fina's signature weapon and her BiS due to its special effect of buffing allies. However, the damage of the weapon itself can largely be neglected when using Fina as a support. This means that a generic damage build such as the one above is serviceable.

Focus on Max Sanity and Skill Efficiency

Fina specializes in supporting allies with her Ultimate which steadily consumes Sanity while it's active. By focusing on Max Sanity and Skill Efficiency, we can maximize the uptime of Fina's abilities, which allows our main DPS to leverage her buffs consistently.

Boisterous Tea Party

Generates an elemental field based on the type of the [Tea Party Guests] - [Nightingale] for Hydro, [Hound] for Pyro, [Unicorn] for Electro, and [Butterfly] for Anemo.

When the field appears or its element shifts, Fina and allies gain bonus elemental damage matching the field's type. While [Boisterous Tea Party] is active, the field also deals elemental damage to enemies within range every 2s.
