About
[Every barcode around you becomes your adventure]
Scan QR codes or product barcodes — characters and gear are generated deterministically. Same code, same hero. Always.
■ Core Loop
· QR code → Companion (character)
· Product barcode → Gear (weapon or armor)
· Bring up to 3 companions on dungeon expeditions (progress even when the app is closed)
· Auto-battle earns Gold and EXP
■ Gacha & Limit Break (latest update)
· Mythic Gacha: spend Gold to pull T7–T10 legendary gear from world mythology
· Limit Break: re-scan the same barcode daily → spend Gold to raise star level (no cap)
· Full Scan Set (barcode weapon + armor): Attack +15%
· Full Mythic Set (gacha weapon + armor): Gold earned +20%
■ Determinism & Permanence
"Same barcode = same hero, forever." Even if the app is gone, your barcode brings back the same companion. Like a charm.
■ Deep Systems
· Prestige & Seals: reincarnate when your hero reaches the required level (scales up with each prestige) for permanent bonuses + stackable seals (Attack / Gold / Soul)
· Collection Multiplier: more gear and monsters discovered = stronger party
· ~3,000 monster species codex
· T1–T10 gear (history of technology → world mythology)
· Five Elements, race bonuses, prefix hack & slash
■ Three Principles (never change)
① Fully offline, zero servers
② Deterministic generation (same code = same result, always)
③ Zero ads
[Pro]
· Team 2 (two simultaneous expeditions)
· Companion renaming
· Camera scan for T10 gear

Reflecting player feedback. ■ Game Balance Adjustments Dungeon difficulty, EXP gain, and Gold rewards have been rebalanced for a smoother experience. ■ Party Roles and Equipment Effects Clarified Defenders help your party reach deeper floors safely. Healers reduce the chance of wipeout. Rarity, Weapon Tier, and roles now visibly affect expedition outcomes. ■ Tavern & Equipment Screens Reorganized Standby members are now grouped by Rarity; weapons are grouped by Tier — easier to manage at a glance.
