Stellar Affinity launch gameplay — pre-registration reward and roster overview

Who Seona is for

Seona is a starter SSR who serves as a reliable early-to-mid game damage dealer. She suits:

• New captains who want a strong SSR from day one without spending
• Players building around the official four-girl roster as a foundation
• Accounts establishing a primary carry before committing to limited banner pulls
• Anyone who benefits from the fire/light imagery archetype and its associated playstyle

Combat role and archetype

Seona functions as a primary damage dealer with a fire/light imagery archetype. Her kit rewards consistent damage output over burst windows. The archetype is flame / guiding light: strong sustained damage, reliable damage profile, and a presence that reads as warm and determined rather than aggressive.

For role wiring in team builds, treat her as a carry slot — she is one of the primary damage options from the launch roster and should be evaluated alongside other carries when planning artifact investments.

Artifact priority

Slot priority	Effect family	Rationale
First	Damage amplification	Maximize her core damage output
Second	Crit scaling	Amplify base damage through critical hits
Third	Sustain or survival	Keep her alive through longer encounters

Build Seona as a primary carry. The flame archetype sometimes creates an expectation of burst damage — her actual profile is reliable sustained damage that compounds over time.

Bond priority

Seona’s affection track should be treated as carry-tier priority once she joins your roster. As a primary damage dealer, she benefits from consistent daily gift and talk habits. Her bond flavor is warmth, determination, and the gentle light that guides the way — the kind of affection that feels like coming home.

Route bond gifts to Seona when:

• She is your designated primary carry
• You are building around the official four-girl launch roster
• Her flame/guiding archetype fits your current progression path

See Hime Bonds and Cumpanions for the affection system overview.

Team placement

Seona fits best in:

• Story clear build — primary carry slot, full artifact investment, bond-first
• Farming compositions — reliable sustained damage for stage clearing
• Four-girl roster build — part of the launch template alongside Delia, Aubi, and Serea

For squad recipes, see best teams and team builds. The official four-girl roster (Delia, Aubi, Serea, Seona) serves as a baseline template for early progression.

How she compares to other carries

Trait	Seona	Other carries
Damage profile	Reliable sustained	Burst or specialized
Imagery	Flame / guiding light	Varied
Team role	Primary carry	Varies
Bond flavor	Warm determination	Affection varies

Seona is designed as a starter-friendly carry: reliable rather than flashy, warm rather than aggressive. She rewards consistent investment over time.

Four-girl launch roster context

Seona is part of the official four-girl launch roster: Delia, Aubi, Serea, and Seona. This roster serves as the game’s baseline template for early progression. Players who pulled Isuna or other limited characters still use the four-girl template as a foundation.

The four-girl roster provides:

• One primary damage dealer (Seona)
• One craftsman/support figure (Delia)
• One playful/energetic character (Aubi)
• One healer/sustain figure (Serea)

This balanced template lets new captains build a functional team from day one while they learn the game loop and save for limited banners.

When to invest in Seona

Invest in Seona when:

• She is your primary carry from the four-girl launch roster
• You are in early-to-mid game and need a reliable damage dealer
• Your progression path benefits from the four-girl roster foundation
• You want a warm, reliable carry who rewards consistent investment

Do not invest when:

• A limited banner carry has replaced her as your primary damage dealer
• Your progression is advanced enough that the four-girl template no longer applies
• You have documented that a different carry better fits your current dock walls
