Weekly Build Discussion: Fina (2026-05-18)
Each week, we will choose a topic and open a weeklong discussion for building & theorycrafting. On most weeks, the chosen topic will be a playable character, but sometimes we may also discuss other types of gear that offer a meaningful decision space. You will be able to find a list of all past weekly discussions in the Subreddit Wiki.

Hi everyone, sorry for missing last week! This week we find ourselves at the Lumino Phoxhunter Summit, and there's a Lumino character who might play a significant role in some team comps: Fina! After losing both her parents to tragic circumstances, she was taken in by Outsider, who helped her experience the childhood she had missed, and start writing her own story. In-game, she boosts her allies' damage and plays with the elements to always hit the enemies where it hurts.
Roles: Support
Skills:
Bad Sorcerers Hate Sunlight! - Passive: Grants additional Lumino damage that lasts forever. Using On a Warm Afternoon or having an active field from Let the Tea Party Begin! grants a stacking buff that grants additional Lumino damage for a duration.
On a Warm Afternoon - Combat skill: Deal Lumino AoE damage in front of you and reduce the movement speed of any targets struck. While the field of Let the Tea Party Begin! is active, using this skill relocates that field to your current position, expands its range to match that field, and increases its damage.
Let the Tea Party Begin! - Ultimate: Create a special field in front of you. This field continuously comsumes your Sanity and ends when you run out of Sanity or when this skill is held. The field will be imbued with an element; all allies will deal an instance of damage in that element when the field appears or shifts. The field also periodically deals damage of the imbued element to enemies inside it. Using this skill again while the field is active cycles the imbued element in this order: Nightingale (Hydro), Hound (Pyro), Unicorn (Electro), Butterfly (Anemo).
Passive upgrades:
Skill Range +30%
Skill Duration +15%
Using On a Warm Afternoon increases all allies' damage based on the number of buff stacks from Bad Sorcerers Hate Sunlight!.
When deployed as a Combat Partner, increases Weapon Damage for self and allies proficient in Swords or Assault Rifles.
Introns:
Lv. 1: Allies buffed by the field from Let the Tea Party Begin! gain PEN for each type of additional damage effect they possess.
Lv. 2: Increase the maximum number of stacks for the buff from Bad Sorcerers Hate Sunlight!, and gain more stacks from your skills.
Lv. 3: On a Warm Afternoon Level +2; Bad Sorcerers Hate Sunlight! Level +1.
Lv. 4: The stacking buff from Bad Sorcerers Hate Sunlight! now also increases your Skill Intensity and Skill Range.
Lv. 5: Let the Tea Party Begin! Level +2; Bad Sorcerers Hate Sunlight! Level +1.
Lv. 6: While the field from Let the Tea Party Begin! is active, Fina gains bonus CRIT Chance on her weapon damage based on the amount of Bonus Effects the target is suffering, and the elemental type of the weapon damage is converted to the target's weakness type.
