You are a cat blacksmith. You hit things with a hammer.
Taking one sword from +1 to +50 changes its sprite fifty times. Its name changes too. From a plain iron blade with a wooden grip, through a storm-etched longsword, all the way to something that shouldn't exist — the screen shows you honestly what is in your hands right now.
5 weapons × 50 tiers = 250 sprites. Every one drawn separately, no scaled-down reuse.
■ Hit it and it changes
One tap, one attempt. No auto-forge, no timing minigame.
It goes up, stays, drops a tier, or breaks.
If it breaks you start from +1 — but your record stands, and the climb back is shorter than the first one.
■ Two kinds of talisman
Guard and Anchor are different objects. They block different things and use separate slots.
Below the break threshold, a Guard is pure waste. Past +41 you want both.
What to slot, and how many, is the only real decision in this game.
■ Five sites, five materials
Oak, Mana Stone, Iron Ore, Silverdust and Flamestone form a ring.
What a weapon mines never feeds its own upgrades. To raise the sword you need what the staff dug up.
That is why all five weapons grow side by side.
■ Boss raid, 100 floors
No party building, no controls. Every weapon you own walks out and fights on its own.
The cat swinging on screen is holding the exact weapon you forged.
What decides your floor is not tapping — it is attack power.
■ It grows while closed
Gathering continues after you quit, banking up to 24 hours.
Come back and one screen tells you everything that happened.
■ About ads
No banners covering the screen. No interstitials jumping out at you.
Every ad is a rewarded one you choose to tap. Skip them and nothing is lost.
Forge success rates are never sold — not for money, not for watching ads.
■ Odds are public
Up, keep, down and break odds for every tier, plus raid drop rates, are readable in-game as a table.
The numbers on screen and the numbers being rolled come from the same code.
Available in English, Korean, Japanese and Traditional Chinese.
One-handed portrait play. Works without an internet connection.
