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.
