Stella Sora Affinity Guide: Gifts, Invites, and Unlocks

How to raise Affinity

Gifts, invites, and each Trekker’s task list contribute to Affinity. A Trekker’s task list is worth 1,800 Affinity.

Gift values and Mail limits

In the captured gifting rules, ordinary gifts are sent through Heartlink → Mail. Gift families include items worth 150, 500, or 2,000 base Affinity. A liked family increases the payout by 50%, while a disliked family reduces it by 20%. For example, preferred 150 and 500 gifts give 225 and 750 Affinity.

The captured gift database lists ten gifts per character per day. A gift given during an invite was observed to use a separate allowance. These gifting rules have not been verified against the current build, so check the allowance shown in game.

Invites and date rewards

A Trekker needs Affinity Lv. 6 before you can invite them. The five daily invites are shared across all Trekkers. An ordinary date awards 200 Affinity, or 215 if its route includes a bonus scene. A date ending with a Special Memory awards 225 or 240. Leaving early still uses the invite.

One gift can be given during a date for double Affinity, separately from the Mail gift limit.

1. Open Invites in the Heartlink app.
2. Select a Trekker and a destination.
3. Choose a route and then choose how the outing ends.

Affinity stages and milestone unlocks

The stages are Acquainted at Lv. 1–4, Friendly at Lv. 5–9, Connected at Lv. 10–14, Devoted at Lv. 15–19, Inseparable at Lv. 20–67, and Soulmate at Lv. 68–99. Affinity levels also raise Trekker HP and ATK until that stat growth stops at Lv. 50.

Trekker Story parts unlock at Lv. 1, 5, and 10. Lv. 10 also unlocks an Affinity Title and the first Affinity Voiceover. Later milestones include archive entries and more voiceovers; the Affinity Title upgrades at Lv. 21, 42, 68, and 99.
