Fina is a Lumino support in Duet Night Abyss built around one idea: keep her tea party running and make everyone’s weapon attacks hit harder. Her kit layers flat damage, elemental bonuses, and penetration on top of Weapon DMG, which makes her one of the strongest partners for rifle and sword carries.
Fina’s role and core strengths
| Attribute | Details |
|---|---|
| Element | Lumino |
| Role | Support (offensive buffer, can become DPS at higher Introns) |
| Ranged weapon | Assault Rifle |
| Melee weapon | Sword |
| Key scaling | Weapon DMG buffs, Elemental DMG buffs, Taleweaver Quill stacks |
Fina excels when paired with characters who deal most of their damage through Weapon DMG rather than Skill DMG. Her passives and Ultimate add:
- Bonus elemental damage of any type (Hydro, Pyro, Electro, Anemo) to allies
- Flat Weapon DMG buffs to sword and assault rifle users
- Teamwide damage bonuses tied to her Taleweaver Quill stacks
She does not provide shields or healing by default and does very little to protect fragile carries, so she usually sits next to a defensive support or healer like Phoxhunter.
How Fina’s kit works
| Skill | Type | Core function |
|---|---|---|
| Let the Tea Party Begin! | Ultimate | Creates Boisterous Tea Party field, consumes Sanity over time, grants elemental buffs and periodic damage. |
| On a Warm Afternoon | Skill | Lumino AoE, slow. Repositions and enlarges the tea party field while it is active. |
| Bad Sorcerers Hate Sunlight! | Passive | Generates Taleweaver Quill stacks over time and when using On a Warm Afternoon. |
| To Be Continued | Passive | Converts Taleweaver Quill stacks into extra damage for Fina and her allies when using On a Warm Afternoon. |
| Advance, Poker Card Soldiers! | Partner passive | Boosts Weapon DMG for allies proficient in Swords or Assault Rifles. |
Let the Tea Party Begin! is the centerpiece of the kit. It creates the Boisterous Tea Party field, which:
- Consumes Sanity continuously while active and ends when Sanity hits 0 or you hold the skill to cancel.
- Cycles through four “Tea Party Guests” when reactivated: Nightingale (Hydro), Hound (Pyro), Unicorn (Electro), Butterfly (Anemo).
- Grants Fina and all allies a bonus to elemental damage matching the current guest.
- Deals periodic elemental damage to enemies inside the field every two seconds.
On a Warm Afternoon is a forward Lumino slash that slows enemies. While the tea party is active, it:
- Teleports the Boisterous Tea Party to Fina’s current position
- Expands the field’s area to match the Ultimate’s full size
- Increases this skill’s damage
Taleweaver Quill is the passive engine behind her damage buffs:
- Each cast of On a Warm Afternoon grants 6 stacks.
- While Boisterous Tea Party is active, Fina generates 1 stack per second.
- The base cap is 30 stacks, increased to 45 at Intron 2.
- Each stack adds extra Lumino Damage and, through To Be Continued, raises team damage further.
Once Taleweaver Quill is fully stacked, Fina can hand out up to roughly 30–45% bonus damage to the team, depending on her Intron level, on top of the elemental and Weapon DMG boosts.
Intron levels and when Fina becomes a DPS
| Intron | Effect | Practical impact | Priority |
|---|---|---|---|
| I1 | Targets empowered by Boisterous Tea Party gain +6% PEN per additional damage type they have. | Big spike in effective damage for your whole rotation when the field is active. | High |
| I2 | Taleweaver Quill cap increases to 45, gains extra stacks per skill use and per second. | Much higher ceiling on team damage buffs and faster ramp-up. | Very high |
| I3 | Levels up On a Warm Afternoon and Bad Sorcerers Hate Sunlight! | Flat stat and scaling increase. | Medium |
| I4 | Each Taleweaver Quill stack adds +2% Skill DMG and +1% Skill Range to Fina. | Strong personal damage and reach, especially in AoE content. | High |
| I5 | Levels up Let the Tea Party Begin! and Bad Sorcerers Hate Sunlight! | More damage and uptime from her main skills. | Medium |
| I6 | During Boisterous Tea Party, Fina’s weapon attacks gain +24% CRIT Chance per bonus effect on the target and convert to the target’s weakness type. | Transforms Fina into a viable on-field DPS with high Weapon DMG. | Very high (if you want her as carry) |
I1 and I2 are the priority for a pure support build: they directly scale the team’s damage. I4 and I6 shift more value into Fina’s own damage, with I6 in particular turning her into a serious main DPS option in Weapon DMG teams once you invest in appropriate weapons and wedges.
Fina stat priority as a support
Fina’s Ultimate constantly drains Sanity, so her stats should first keep Boisterous Tea Party online, then scale its damage and her Quill buffs.
| Stat | Priority | Why it matters |
|---|---|---|
| Skill Efficiency | Core | Reduces Sanity consumption, directly extending Ultimate uptime. |
| Skill Duration | High | Lengthens buff and field duration, synergizing with Skill Efficiency. |
| Skill DMG | High | Boosts Boisterous Tea Party ticks and Taleweaver Quill damage. |
| Max Sanity | High | Gives a larger resource pool to spend on continuous field uptime. |
| ATK | Medium | Improves Fina’s personal damage, especially at higher Introns. |
| Skill Range | Low | Only affects the radius of the damaging field, not the reach of the buff. |
The elemental bonus from Boisterous Tea Party applies to all allies when the field appears or changes element, regardless of where they stand. That makes Skill Efficiency, Duration, and DMG much more valuable than Skill Range for a support-focused build.
Best Demon Wedge loadout for support Fina
Fina’s ideal wedge setup stacks Skill Duration, Sanity sustain, and ATK while fitting under her Tolerance cap. A typical endgame configuration looks like this:
| Slot | Demon Wedge | Main effects |
|---|---|---|
| Core | Rescue | Heals teammates on Ultimate cast; significantly increases max Tolerance. |
| 1 | Prismatic Neon | +Skill Duration; increases CRIT Chance on enemies near a Lumino character taking Weapon DMG, higher vs debuffed targets. |
| 2 | Skylume • Midnight Sun | +Lumino ATK, +Skill DMG, +Skill Duration. |
| 3 | Wings • Inspo | +Max Sanity, +Skill Efficiency. |
| 4 | Prime • Serenity | +ATK/HP/DEF; restores extra Sanity to the whole team every 3 seconds. |
| 5–8 | Blaze • Eternity ×4 | +ATK, +Skill Duration; equippable in multiples at +5 refinement. |
This layout reaches 111 Tolerance out of a base 100, which is legal once Rescue is leveled (it increases the max Tolerance by a factor of its requirement). The result is:
- Very high Skill Duration from Blaze • Eternity, Prismatic Neon, and Skylume • Midnight Sun
- Extra Sanity, Sanity restoration, and Skill Efficiency to feed the Ultimate
- Meaningful ATK and Skill DMG scaling for both Fina’s ticks and Quill damage
When another support is already running Prime • Serenity, you can replace Fina’s copy with Prime • Uplift or another offensive wedge to avoid redundancy.
Best melee weapons for Fina
| Rank | Melee weapon | Notable skill effect | Use case |
|---|---|---|---|
| 1 | Remanent Reminiscence | Increased ATK range; CRITs have a high chance to restore Sanity, with a short internal cooldown. | Top choice for support Fina to offset Sanity drain while fighting. |
| 2 | Tetherlash | Large Skill Duration bonus. | Alternative when you want even more duration and can manage Sanity elsewhere. |
| 3 | Pyrothirst | Large Skill Duration bonus. | Similar to Tetherlash; flexible pick when Remanent Reminiscence is unavailable. |
For pure support, Remanent Reminiscence is hard to beat. Its Sanity restore on CRIT lets Fina actively attack with her sword to refill the resource that keeps Boisterious Tea Party running. Tetherlash and Pyrothirst are good if you already have strong Sanity sustain from wedges and want to push duration instead.
At Intron 6, when Fina is used as an on-field DPS, any high-ATK or high-attack-speed weapon becomes attractive; the priority shifts to raw Weapon DMG stats rather than utility.
Best ranged weapons for Fina
| Rank | Ranged weapon | Skill effect | Why it fits Fina |
|---|---|---|---|
| 1 | Dreamweaver's Feather | +Skill Range; when a Lumino character deals bonus damage, has a chance to grant allies an ATK% buff that stacks up to 10 times. | Signature support rifle that adds a huge, stackable ATK buff on top of Fina’s own damage boosts. |
| 2 | Arclight Apocalypses | +Skill Duration; CRITs randomly grant allies ATK, DEF, Skill DMG, or Skill Duration buffs. | Strong alternative that adds both duration and flexible team buffs. |
| 3 | Osteobreaker | +Skill Duration. | Simpler stat stick that still pushes her uptime and works when signatures are missing. |
Dreamweaver’s Feather is tuned specifically for Fina’s role as a buffer, layering a potent ATK% buff on any team that already benefits from her elemental and Weapon DMG boosts. Arclight Apocalypses leans harder into hybrid support, tossing out random but useful buffs whenever she crits. Osteobreaker trades utility for straightforward duration and is easy to use as a placeholder.
Best Fina team compositions
Fina’s buffs favor weapon shooters and slashers over casters. She shines in Weapon DMG–centric lineups built around sword and assault rifle carries.
| Slot | Character | Role | Synergy with Fina |
|---|---|---|---|
| DPS | Lynn | Main Weapon DMG carry | Consonance Weapon plus strong Weapon DMG scaling fully leverages Fina’s buffs. |
| Support 1 | Fina | Offensive support | Provides elemental bonus damage, Weapon DMG boosts, and damage amplification through Taleweaver Quill. |
| Support 2 | Phoxhunter | Support / defensive utility | Adds additional Weapon DMG buffs and teamwide Ultra Shields for survivability. |
| Geniemon | Pyrelf | Primary | Pyro Geniemon that further raises Weapon DMG output. |
| Geniemon alt | Zippyro / Pyrootail | Alternatives | Backup Pyro options if Pyrelf is missing. |
Other strong front-line partners include Psyche, Lisbell, Outsider, and Berenica, provided they scale heavily with Weapon DMG. Skill DMG–oriented characters benefit much less from Fina’s buffs and usually belong in different compositions.
In play, the rotation is straightforward:
- Swap to Fina and cast Let the Tea Party Begin! to establish the field and grant the elemental buff.
- Use On a Warm Afternoon a few times to build Taleweaver Quill and reposition the field as needed.
- Swap to your main DPS (for example, Lynn) and unload Weapon DMG skills and attacks inside the buff window.
- Return to Fina to refresh Boisterous Tea Party, re-stack Quills, and keep the buff nearly permanent.
How to play Fina in combat
Fina’s gameplay loop focuses on three habits: keep the party up, keep Quills stacked, and use your weapons.
- Keep Boisterous Tea Party active. Try to maintain field uptime for most of the fight. Manage Sanity with Remanent Reminiscence, Prime • Serenity, and Skill Efficiency rolls; do not be afraid to briefly turn the field off if Sanity gets dangerously low.
- Build Taleweaver Quill to the cap. Open fights with a quick sequence of On a Warm Afternoon casts, then let the passive stacking during Boisterous Tea Party do the rest. At higher Introns, banking 45 stacks becomes the goal.
- Fight with your weapons. Fina is not a pure “press buff and leave” support. Her field damage, Quill procs, and Sanity restoration benefits from her actively attacking, especially with her melee weapon.
- Pair her only with Weapon DMG carries. Dropping her into a Skill DMG team wastes most of her value. Stick to sword and rifle mains and Weapon DMG–focused characters.
Once her field, Quills, and wedges are set up correctly, Fina effectively turns your main carry into an all-element weapon turret, with penetration, bonus elemental hits, and ATK buffs stacked on top. That is where her build pays off.
