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

Bug fix. Fixed an issue where expeditions always showed "Turned back" even when the party reached the target floor. Reaching your goal now correctly shows as a success.
