StarSavior Gray Research Summon Priority and Banner Guide

For the September Gray Research campaign in the Global version of StarSavior, your primary action is to exhaust all 300 free observations before spending premium summon currency. Once those free pulls are claimed, prioritize securing a base copy of the returning top-tier unit, Eternal Vow Carmen, if you do not already own her. Treat the new arrivals, Professor M and Quinn, as optional additions based on specific roster needs.

1. Exhaust the 300 Free Observations First

The Gray Research campaign awards 300 free observations (summons) through event distributions. Because free pulls award character shards, rank-up fodder, and potential off-banner SSR units, spending premium currency beforehand creates unnecessary risk.

• Hold your Stellar Stones and Observation Tickets: Do not draw on rate-up banners until you have finished every daily or milestone-gated free observation.
• Avoid premature duplicate choices: Keep universal duplicate chests or selection items unopened until the free summon pool has been completely redeemed, preventing redundant pulls.
• Track the campaign timeline: Verify that all 300 observations are redeemed within the September event window so no free allocations expire.

2. Priority Target: Eternal Vow Carmen Rerun

Eternal Vow Carmen serves as the central rerun banner during this event and represents the highest-value spending target for accounts lacking her. Her utility, survivability buffs, and offensive amplification make her a core support across general PvE stages and competitive modes.

Use this breakdown to determine your investment level:

If you already own Carmen at base SSR, chasing extra copies offers diminishing returns for free-to-play and light-spending players compared to saving for future operational cycles.

3. Evaluating Professor M and Quinn

Professor M and Quinn debut alongside the campaign as specialized units rather than universal requirements. Neither unit replaces foundational generalists, so summon them only if your roster has a clear functional void.

• Professor M: Focuses on debuffs and tactical control. Consider pulling only if your composition lacks reliable crowd control or disruption tools for high-difficulty bosses.
• Quinn: Focuses on sustained performance and physical follow-up mechanics. Consider pulling only if your team needs a dedicated driver for physical or follow-up damage engines.

If your existing assault and support units already clear daily content and Sector bosses comfortably, skip both banners to protect your reserves.

4. Visual Updates and Light/Dark Models

The update introduces visual enhancements, including battle-damaged cosmetic states for select Light and Dark element units. These additions are purely aesthetic features and visual quality-of-life updates. They provide no combat ratings, skill multipliers, or stat enhancements. Do not spend Observation Tickets or premium currency to chase cosmetic variants at the expense of functional character recruitment.

Step-by-Step Spending Roadmap

Follow this sequence to avoid wasting summoning currency during the Gray Research update:

1. Redeem all free pulls: Complete the full 300 free observations across the event schedule.
2. Pull Eternal Vow Carmen: If she is not in your roster, spend saved premium tickets until you obtain one copy.
3. Assess roster gaps: Review your teams to see if Professor M's control or Quinn's follow-up mechanics solve a current progression bottleneck.
4. Bank the remainder: Once Carmen is secured and free pulls are finished, save all surplus currency for upcoming operational banners.
