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 QR Code is a registered trademark of DENSO WAVE INCORPORATED.

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.
