Quick answer: the Ruins Giant Monster Mystery event runs September 22, 2026 12:00 JST through October 27, 2026 11:59 JST. It adds a 15-floor giant monster ruins run, the Garuda strong enemy match (unlocks with chapter 1), the Gigantes Army multi quest (unlocks with chapter 2), and a chapter 3 wave that opened October 6, 2026. Collect charm stones and spend them in the event exchange, and claim the 1,600 gem login bonus while the window is open.

Chapter Waves and Unlocks

The event opened in three waves. Each wave adds story progress and unlocks more of the event content.

DateWhat opened
September 22, 2026Event story chapter 1, Garuda strong enemy match, Sacred Arts Series banner
September 29, 2026Event story chapter 2, Gigantes Army multi quest
October 6, 2026Event story chapter 3

Unlock order matters because the event adventure skills come from story progress. Clearing story first, then running the ruins, the strong enemy match, and the multi quest keeps your damage scaling up instead of fighting the newest boss with level 1 event skills.

Two unlock checks are worth remembering:

  • The Garuda strong enemy match opens after clearing event story chapter 1.
  • The Gigantes Army multi quest opens after clearing event story chapter 2.

The Giant Monster Ruins Route

The signature mode is the giant monster ruins, a repeatable run with a random layout each attempt.

LayerDetail
Total floors15 floors, compact compared with earlier ruins style events
Boss gatesA boss waits every 5 floors
Deepest pointGigantes, the giant monster the event is named for
Failure ruleRewards you already picked up are kept even if the run ends early
ShopA Momonja Shop appears on the route and sells adventure skills and items for monster coins
Event doorA branching door adds a special rule and can grant a strong event skill worth three normal upgrades

Two practical notes. First, the shop is where monster coins turn into power, so bank coins for the shop before spending them anywhere else inside the run. Second, the branching door can hand you a much stronger skill than a normal pickup, which is the cheapest way to push a deeper attempt.

Rewards and the Charm Stone Exchange

Charm stones are the event currency. You earn them from the ruins, the Garuda strong enemy match, and the Gigantes Army multi quest, and you spend them in the event exchange.

RewardCharm stonesLimit
Limited accessory (あくまのしっぽ)5,0001 time
Gems x5050010 times
Gigantes stamp10,0001 time
Gigantes icon frame6,0001 time

Treat the exchange like every other limited shop: take the limited accessory and the gem stacks first, then cosmetics, then filler. The exchange closes with the event, so unused charm stones have no value after October 27, 2026 11:59 JST.

New Memories in This Event

The event adds several limited Memories. The two with the clearest farm routes are tied to the Garuda match and the Gigantes Army multi quest.

MemoryWhere it dropsMain effect
Gigantes Army (multi quest)Gigantes Army multi questDark physical damage +7%, top-class recovery magic
Garuda (strong enemy match)Garuda strong enemy matchEarth physical damage +8%
Gigantes (ruins)Giant monster ruinsEvent ruins drop
Mage Chimera, ShadowEvent dropsEvent drop Memories

The Gigantes Army Memory is the strongest of the group on raw stats because it leads the recovery magic stat line, which makes it a natural fit for a support or hybrid slot rather than a pure damage slot. Confirm the Memory you want before spending repeat runs on one mode, because each mode pays a different Memory.

Event Equipment and Banner

Two new pieces of equipment are tied to the event, plus two limited banner sets.

ItemAcquisitionNote
Event accessory (ドクロのゆびわ)Event drops and exchangeEvent accessory
Limited accessory (あくまのしっぽ)Charm stone exchangeLimited accessory
Black Condor (ブラックコンドル)Sacred Arts Series bannerEarth boomerang, weakens enemies
Yami no Yari (常闇のやり)Dark Knight Series bannerDark spear, first 3-star dark spear

The current banner guide covers both limited banners and the pull or save decision, and the Black Condor data page covers the earth boomerang.

Daily Loop

  1. Claim notices, login rewards, and the event login bonus before spending stamina.
  2. Push the event story if a chapter is still uncleared, because story progress raises the event adventure skills.
  3. Run the giant monster ruins for monster coins and charm stones.
  4. Run the Garuda strong enemy match once its missions are clearable.
  5. Run the Gigantes Army multi quest when you can fill a party.
  6. Spend charm stones in the exchange before the window closes.

The daily loop is intentionally short. The event pays charm stones from three modes, so rotating them beats grinding one mode to the point where it stops being efficient.

FAQ

Can I still finish the event if I start late?

Yes, but the whole route is open only until October 27, 2026 11:59 JST. Start with the event story so the Garuda match and the Gigantes Army multi unlock, then run the ruins for charm stones. A late start mainly costs you repeat runs, not access.

Do I need the new banner weapons to clear the event bosses?

No. Earth and dark weapons carry the event, and you can cover both with weapons you already own, such as the Sand Spear for earth or a dark weapon from an earlier banner. Pull only when the new weapon fills a real gap on your account.

Which event mode should I farm first?

The ruins first, because they pay both monster coins and charm stones and you can run them solo. Add the Garuda match once your missions are reachable, and add the Gigantes Army multi when you can fill a coordinated party.
