Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1/day in the week to Aug 3 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Equipment & Badge Enhancement
Equipment can be enhanced to raise its level, with different quality tiers offering different enhancement caps. The badge system provides additional stat bonuses with enhancement up to +100 levels. Soul Badges are a separate advanced badge line with their own progression curve and visual glow effects.
Awakening System
All 6 heroes can Awaken into ultimate classes with new combat mechanics and skills. Each Awakened class plays differently.
Endless Defense
Tower-defense style wave combat. Build-craft with the affix system. Each hero has a dedicated defense talent tree.
Paragon Talents
Endgame progression system unlocked after all heroes are Awakened. Hexagonal talent board with a shared talent point pool.
Artifact System
12 Zodiac constellation artifacts, each with unique combat effects. They drop naturally over time and are displayed in your Artifact Cabinet.
Forge Temple
20+ difficulty tiers of challenge dungeons. Enemies have Demonic Shields that must be shattered. Choose heroes for training, collect materials, and craft Mythical Equipment with random stat affixes.
Auto Challenge
Hands-free stage progression with main-story-only mode, automatic work-for-gold switching, and auto-harvest.
Builds & Synergies
Awakened classes, cards, defense affixes, talents, and artifacts can combine in interesting ways. For example:
Awakened Archer with talents and the Sagittarius artifact, multi-shot melting enemies
Awakened Priest with passives and Paragon talents to wipe the entire screen
Awakened Guardian stacking reflect and shields — the more enemies hit you, the stronger you get
Awakened Warrior burning HP with lifesteal, getting deadlier the closer to death
Awakened Dancer stacking evasion to 100% for permanent invincibility, grouping enemies and detonating them all at once
Different build paths lead to different combat experiences — worth experimenting with.

没想到这个价格能买到这么不错的挂机游戏。这游戏最大的好处就是不需要抽角色和掉落武器,挂机就能明显看到人物变强。

ของดีจริงๆ ระบบค่อนข้างลึก เล่นได้นาน ช่วงลดราคาเหลือ 40 กว่าบาท คุ้มเกินคุ้ม Idle ที่แท้ทรู
內容量和價格無敵,更新還很頻密,非常有誠意的作品! 遇到的bug: 暫無 製作組無敵了,留言後2天就修好了!! 希望優化: 徽章新增升級到max lvl選項,右鍵一次10級其實還好,但一次性要升級十幾個徽章有點讓人著急 DPS checker,傷害很不直觀,不知道怎麼組build才能最大化收益 完整角色數據預覽,感覺和DPS選一個出都行,主要是目前數據不夠明確 DLC,無論是純外觀的support pack還是有新內容的DLC都歡迎,希望能支持你們推出下一個作品
上班摸鱼很爽
