Your master left for the north with nothing but a note. "Look after the forge. Don't set the anvil on fire." The smithy is yours now. Mine the ore, smelt the iron, and combine blades, grips and guards into swords. Hand those swords to knights and send them into dungeons. What they bring back becomes a better sword, and a better sword reaches deeper. Work continues while the app is closed. Your miners and workbenches keep going, and materials are waiting when you return. ■ What you do · Combine blades, grips, guards and jewels into your own swords.

Every purchase shows exactly what you get. · Rewarded ads only. You watch when you choose to, and never have to. · Plays fine offline. · Available in Korean, English, Japanese, Traditional Chinese, German, French, Spanish and Portuguese.
