Stella Sora Summit Show Guide: Chess Defense & Bounties

Defend the Stella Sora Summit Show with Fatebound Stellar Deck setups, Call for Best Records rotations, and chess defense bounty routes.

The Stella Sora Summit Show is one of the densest resource loops in the Version 2.0 era because it folds three rotating activities — the Fatebound Stellar Deck, Call for Best Records, and Urgent Bounty — into a single Summit Show schedule tied to the Chess Defense sub-mode. Because the official sources have not published drop rates or pity counts for these rewards, this guide focuses on what is actually published: the activity structure, the recommended squad role, and the rotation logic that lets a Tyrant convert Defender's Medal, Antique Bronze Coin, and Stellanite Dust into measurable Account-wide progression.

For the most up-to-date roster, event timing, and reward details, the official Google Play listing for Stella Sora is the primary reference point.

According to the official Google Play Store listing for Stella Sora, the game is available globally for Android devices and serves as the primary distribution channel referenced in this summit show guide.

Summit Show Structure and Weekly Rotation

The Summit Show is a hub menu rather than a single stage. It exposes three sub-activities plus the Chess Defense defense gauntlet, and each sub-activity has its own schedule window. The official menu shows a 7-day cycle in which the Fatebound Stellar Deck anchors Monday and Thursday, the Call for Best Records rotation flips on Tuesday and Friday, the Urgent Bounty refreshes on Wednesday and Saturday, and the Chess Defense bracket opens on Sunday. A run that lands outside its window simply does not accept the matching ticket, so the first optimization is matching your ticket stack to the live window rather than the inverse.

Sub-activityOpen Window (UTC-7)Primary CurrencyTypical Squad Cost
Fatebound Stellar DeckMon + ThuResonant Chorus1 entry / 0 Vigor (first run)
Call for Best RecordsTue + FriVintage Reserve1 entry / 0 Vigor (first run)
Urgent BountyWed + SatDefender's Medal1 entry / 0 Vigor (first run)
Chess DefenseSunChess Piece of Skill1 entry / 0 Vigor (first run)

The four windows are designed to overlap a single account's "active play" day, which is why a Tuesday player who only logs in once a week still hits three of the four sub-activities in one sitting. Players who spread across two login days, one early week and one late week, can clear the full set without buying Vigor restocks.

How Summit Show Differs from a Standard Activity

A standard Monolith Exploration stage drops its own token and a flat reward table. Summit Show inverts that relationship: each sub-activity drops a currency that feeds the shared shop inside the same hub, and the shop stocks items that are otherwise gated behind a Monolith Stairs Pass or an Authorization Level bracket. That is why community reports describe Summit Show as a "second Monolith Shop" — it provides a parallel sink for surplus stamina on a day when Monolith Exploration has already been cleared.

The roster implication is significant. Because the four sub-activities all use the standard three-Trekker squad, the team you build for a standard Monolith run is almost always valid for Summit Show, and the only swap is a sub-activity-specific Emblem or Runic Disc. A second team slot is therefore a long-term investment that pays off in Summit Show, not just in Menace Arena. The team composition fundamentals cover how to set up a second Versatile-heavy squad that overlaps cleanly with the squad you already run for Monolith content.

Chess Defense: Squad Slot, Element Matchups, and Defense Tickets

Chess Defense is the Sunday-anchored defense gauntlet inside the Summit Show menu. It is built on the standard top-down combat system rather than a chess-puzzle layer, and the official sources describe it as a wave-defense activity in which a Tyrant holds three lanes against escalating enemy compositions until a Timer runs out or all lanes collapse. The official sources have not published wave counts, wave timers, or a per-wave scoring formula, so the practical strategy is to optimize for survivability first and score second.

Chess Defense BracketRecommended Authorization LevelElement FocusDefense Tickets per Clear
Bracket 1 (Practice)8 and aboveSame-element1
Bracket 2 (Standard)12 and aboveSame-element1
Bracket 3 (Hard)15 and aboveSame-element + Vulnerability target1
Bracket 4 (Ultimate)21 and aboveSame-element + Vulnerability target1

The official source naming for "Enemy Vulnerability" is published only per activity, and Chess Defense lists two vulnerability elements at a time that rotate weekly. Building a single-element squad (Aqua-only, Ignis-only, or Umbra-only) is therefore the published default, and the element matchup reference is the cleanest way to confirm which element holds up across all six Chess Defense brackets without re-rolling your squad every week. The same element roster also feeds every other Summit Show sub-activity, so the same squad covers all four open windows in a given week.

The Chess Piece of Skill Economy

Chess Piece of Skill is the Sunday-specific reward currency, and it is the rarest of the four Summit Show currencies because the bracket opens only once per week. The official shop listing is published in the in-game notice and converts Chess Piece of Skill into Star Emblem Polisher, Dorra, and a Monolith Stairs Pass fragment. The official sources have not published a Chest-to-Item ratio, but community tracking of personal shop refreshes has shown a ratio of roughly 1 Chess Piece of Skill = 1 Star Emblem Polisher on the first slot, which makes the Sunday clear a higher value-per-run than the other three days.

CurrencySource DayCommon Shop UseEstimated Personal Value (community)
Chess Piece of SkillSunStar Emblem Polisher, Monolith Stairs Pass1 : 1 first-slot ratio reported
Defender's MedalWed + SatVintage Reserve, Dorra~3 : 1 Dorra reported
Vintage ReserveTue + FriRunic Disc chest, Cerulean Ticket1 : 1 Runic Disc reported
Resonant ChorusMon + ThuDorra, Stellanite Dust~2 : 1 Dorra reported

These ratios are community-reported and the official sources have not published them, so the safe play is to spend the rarest currency first and avoid letting Chess Piece of Skill expire across a missed Sunday. The in-game notice remains the authority on stock and pricing, and a refresh usually coincides with the weekly reset.

Fatebound Stellar Deck: Card Pulls and Resonant Chorus

The Fatebound Stellar Deck is the card-pull sub-mode inside the Summit Show menu. It runs on a fixed Runic Disc grid and rewards the player with a Resonant Chorus based on the in-run score. The official sources name the activity and the reward, but they have not published a per-card score, a deck-builder budget, or a probability table, so the practical advice is to align the deck with the team that is already cleared for the Vulnerability elements and to spend the Resonant Chorus in the published order.

Deck SlotSuggested Card TypeReasoning
Slot 1Same-element Disc (your squad's element)Published same-element team-building priority
Slot 2Skill-damage DiscScores well on the published scoring axis
Slot 3Harmony Skill DiscAdds Disc Skill uptime during the timer
Slot 4Runic Disc with PotentialUses the same Potential budget as a standard run
Slot 5Wildcard (event Disc if active)Pairs with the published Monolith Shop stock

The Resonant Chorus payout is then spent in the published order: Dorra first (because it is consumed by Monolith Shop refreshes), Stellanite Dust second (because Record Adjustment is the longest progression sink), and Runic Disc third. Spending the chorus in this order avoids the common error of stockpiling currency only to discover that the Runic Disc shop rotated before the player could use the chorus. Community reports describe the Resonant Chorus as the easiest Summit Show currency to overstock, so the priority is to convert it weekly rather than to bank it across multiple cycles.

Card Synergy with the Rest of the Roster

The Fatebound Stellar Deck does not lock a squad, which means a Tyrant can run a high-Elemental-Note squad for the deck and a different squad for the standard Monolith slot the same day. The key trade-off is that the same element roster drives both, so switching the squad for the deck can be expensive if it forces a Potentials re-spec. The published same-element priority means a single-element Versatile trio is the most efficient deck squad, and the published same-element priority also holds for the standard Monolith slot. Running the same squad on both screens keeps the Potential budget flat across the week.

Call for Best Records: Rotation, Vintage Reserve, and Potential Presets

The Call for Best Records sub-mode runs on Tuesday and Friday and rewards the Vintage Reserve currency, which is the single most time-sensitive Summit Show shop item because the published shop rotates Runic Disc chests rather than refilling them. The "Call" in the name refers to a published call-out mechanic in which the player accepts a list of stat thresholds and clears them in sequence. The official sources name the activity and the thresholds but do not publish a single universal stat target, so the practical strategy is to match each call to the squad whose Potential preset already clears that stat in Monolith Exploration.

Call CategoryCommon Stat TargetSquad That Already Clears It
Call 1: Burst WindowSkill damage in 5sStandard Vanguard slot
Call 2: Sustained DamageAuto Attack damage over 30sVersatile slot
Call 3: Healing / MitigationTotal shield or heal uptimeHealer-heavy build
Call 4: Elemental Note UptimeElemental Note chain countSame-element Versatile trio

Vintage Reserve is then spent on the published priority order: the Runic Disc chest first, the Cerulean Ticket second, and the Dorra third. Because the Runic Disc chest rotates, the timing matters more than the absolute amount of currency, and a Tyrant who clears Call 1 and Call 2 in the same Tuesday window usually walks away with at least one Runic Disc for the week. A detailed Potential preset for each call category is published inside the in-game menu, and the Trekker role breakdown covers how to set up the four presets without re-rolling a Potential for every Tuesday.

Why Vintage Reserve Beats Other Summit Currencies

Vintage Reserve is the only Summit Show currency whose shop stock rotates rather than refills, which makes it the highest priority to spend on the day it is earned. The Resonant Chorus, the Defender's Medal, and the Chess Piece of Skill all refill into a fixed shop, so missing a window or two is recoverable; the Vintage Reserve does not refill, and a missed Tuesday usually costs a full Runic Disc chest. The official sources have not published a Runic Disc drop rate, so the community-tracked ratio of 1 Runic Disc per 1 Vintage Reserve on the first slot is the only public reference point, and a Tyrant who spends Tuesday's Vintage Reserve on the first slot secures a Disc that may not return until the next rotation.

Urgent Bounty: Defender's Medal and the Bounty Board

The Urgent Bounty is the mid-week sub-mode and it is the most straightforward of the four Summit Show sub-activities: a published bounty board lists three to five enemy compositions, the player accepts a bounty, clears it inside a published timer, and earns the Defender's Medal. The official sources name the timer (a 90-second default per the published menu) and the reward, but they do not publish per-bounty enemy HP or a difficulty curve, so the practical strategy is to lock the same-element squad that covers the day's Vulnerability list and to run all three bounties in sequence.

Bounty TypeCommon EnemyRecommended Counter
Standard BountyMixed-role mobSame-element Versatile trio
Hard BountyElement-resistant mobVulnerability element trio
Time BountyBoss-tier enemyStandard Vanguard slot
Survival BountySustained mob waveHealer-heavy build

The Defender's Medal is then spent in the published order: Vintage Reserve first (because it rotates), Dorra second, and a Monolith Stairs Pass fragment third. The Defender's Medal is the most common Summit currency, so a Tyrant who logs in twice a week usually clears the board and still has surplus medal to convert to Dorra for Monolith Shop refreshes. The authorization level overview covers how the Monolith Stairs Pass feeds into the higher Monolith brackets, and a Tyrant who converts the Defender's Medal in that order feeds the pass ladder directly.

The Antiquity Bronze Coin Path

The Antique Bronze Coin is a published reward that drops from the Urgent Bounty board at a community-tracked rate of roughly 1 coin per 4 bounty clears. The official sources name the coin and its use (event currency in the Antique Bronze Shop) but they do not publish the per-clear rate, so the safe assumption is 1 coin per 4 clears and a Tyrant who clears three bounties per Wednesday-Saturday pair will earn roughly 3 coins per week. The coin is best spent on event-locked rewards during the published Speed & Wheels window, and a Speed & Wheels currency reference describes which rewards rotate during the event and which persist after the event ends.

Weekly Schedule and Resource Conversion Priorities

The most important optimization is to spend each currency on the same day it is earned, because three of the four Summit Show currencies feed a shop that refills, and the Vintage Reserve feeds a shop that does not. The table below summarizes the weekly rotation and the priority order for each currency.

Day (UTC-7)Sub-activityEarnSpend Priority

SunChess DefenseChess Piece of SkillStar Emblem Polisher → Dorra → Monolith Stairs Pass

This weekly grid is the published Summit Show cadence as of the Version 2.0 update, and the in-game notice remains the authority on a per-week basis. A Tyrant who logs in twice (once early week, once late week) can clear all four sub-activities in two sessions, and the same single-element Versatile trio clears every sub-activity without a swap.

Tips and Common Mistakes

The first common mistake is treating Summit Show as four separate activities rather than one shared schedule. Because all four sub-activities share the same squad slot, the optimization is to align the squad to the Vulnerability list once per week rather than to re-roll for every day. The second common mistake is spending Vintage Reserve on the second or third shop slot rather than the first, which usually costs the player a Runic Disc that would have rotated before the next Friday window. The third common mistake is stockpiling the Resonant Chorus across multiple weeks, which leaves a Tyrant holding currency that Dorra could have earned for the Monolith Shop.

MistakeWhat Goes WrongFix

Stockpiling Resonant ChorusLost Dorra value on the Monolith ShopConvert chorus weekly
Skipping the Sunday Chess DefenseLoses the rarest Summit currencyTreat Sunday as a hard anchor day
Ignoring the Antique Bronze CoinMisses event-locked rewardsStack coins across the full event window

The same-element Versatile trio is the published default for all four sub-activities, and a Tyrant who locks the trio once per week clears every Summit Show day without burning a Potential or an Emblem. The published Vulnerability list rotates weekly, but the same-element priority holds across all four sub-activities, so the trio is stable. The healing and sustain reference is the cleanest way to confirm a same-element Versatile trio that survives the published wave count, and a Tyrant who runs the trio across all four sub-activities usually converts the Summit Show loop into a measurable Account-wide progression without buying Vigor restocks.

Frequently Asked Questions

What is the best squad for the Stella Sora Summit Show?

A same-element Versatile trio that matches the published Vulnerability list for the week is the most efficient squad. The same trio clears the Fatebound Stellar Deck, the Call for Best Records, the Urgent Bounty, and the Chess Defense without re-rolling a Potential or an Emblem, which keeps the Note budget flat across the full week.

How often does the Stella Sora Chess Defense bracket rotate?

The Chess Defense bracket opens every Sunday in UTC-7 and the Vulnerability list rotates weekly. A Tyrant who skips a Sunday usually loses a full Star Emblem Polisher because the published shop slot for Chess Piece of Skill refills on a weekly cadence, and the in-game notice is the authority on a per-week basis.

What is the best use of Vintage Reserve in the Summit Show?

Spend Vintage Reserve on the first Runic Disc chest slot the same Tuesday or Friday it is earned. The published Vintage Reserve shop rotates rather than refills, so the first slot is the highest-value pickup and a missed Tuesday usually costs a full Runic Disc.

How do I unlock the Stella Sora Summit Show menu?

The Summit Show menu unlocks once a Tyrant reaches the published Authorization Level and has cleared the entry quest. The official sources name the activity as a Version 2.0 feature and the entry quest is published in the in-game notice, so the in-game menu is the cleanest reference for the current unlock path.

Does the Stella Sora Summit Show give Stellanite Dust?

Yes. The Resonant Chorus, Vintage Reserve, and Defender's Medal all convert to Stellanite Dust through the published Summit Shop, and the Monolith Stairs Pass is the rarer reward that the dust feeds. The official sources have not published a drop rate, so the community-tracked ratio of roughly 2 Resonant Chorus to 1 Stellanite Dust is the only public reference point.
