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.

For the price, it's a fun desktop game. The first few "chapters" were enjoyable. The problem is once you pass those beginning ones, the game basically becomes automated and the only thing that matters is gold collection. Even that, though, can be automated. You turn on "Auto Challenge," leave on the setting to allow them to farm gold when needed, and ignore it. They'll just keep clearing chapters on their own. If it gets stuck, you leave them farming gold for a while to upgrade stats, and then you get back to it. The game could probably beat itself if you just left your computer on at night. It's not even an auto-battler at that point, because you don't need to choose formations or gear or anything. It's just an auto-game... You could not turn on the auto challenge feature, but there are over 600 "chapters," each with a few dozen zones. It would be almost peak tedium. I have no suggestions to fix this. I still think the initial few chapters are worth it for the price. It just hit a very specific point for me where it ceased to be a "fun game" and ended up a background program I couldn't even be bothered to check.
很少评价,但是这个游戏真的好玩,性价比太高了,我玩了这么多挂机游戏,这个能排前几名

作为桌面小游戏,内容真丰富。 就是场景直接复用了,看多了没啥新意。
狠狠地挂机
너무 멋진 게임 방치형 게임 중 탑임 제작자한테 너무 고마움 할수록 다양한 컨텐츠가 풀림~ 천천히 오래 즐기실 분들은 꼭 사서 해보세요
前期很好玩,后面好像有新内容,但是中期的重复度太高了,坚持不住,曲线不太合理。 美术很棒。小人画的是真不错。可以爽完一天。成就非常友好。
游戏总体来说还是比较好玩的,10块钱物超所值! 游戏前中期体验较好,正反馈给的很足、很频繁,每隔一段时间都有新系统开启,战力能肉眼可见的提升。 后期从神殿开始稍微有点无聊,进入了漫长的挂机收菜阶段,但是挂机一天后打造装备还得看脸,脸黑没有弄到想要的词条的话相当于一天0提升。而且从前期进入到神殿难度跨度有点大,前面是无脑爽爽爽秒怪,到了神殿就开始刮痧了,得慢慢刮攒材料把装备打造好体验才有所提升。 到了龙之大陆就更不用说了,又是看脸洗词条,又是挂一天可能0提升。希望作者说的保底能尽快端上来。 总体来说游戏还是不错的,对得起10块钱这个价格,前期爽玩,后期想爽玩的话还是建议SL好一点,毕竟运气不好挂一天0提升大部分人还是接受不了。
特别好评,一切体验都刚刚好,隐藏起来也不耽误事。十分开心,已加群,会视奸游戏进度,我会一直盯着一直、一直、一直......
8块钱的挂机小游戏,好玩
