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 2,400 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.

One of the best RPG Idles I've played, period.
性价比极高的桌面挂机放置rpg,内容丰富难度不高,玩起来非常舒服
游戏模式还是可以的,但整体感觉缺一个靠谱的数值策划,我都全成就了都没什么感觉,随便打一通就过了,没有挂机解决不了的问题。国外团队做的吗?数值不能这么拉啊。

上班摸鱼使用非常方便
켜놓고 딴짓하기 좋음. 근데 후반갈수록 진행이 느려져서 배속 가능했으면 함
最好的桌面放置游戏,性价比很高,而且还在持续更新。 很难想象一个放置游戏居然做了高级转职和卡片掉落,有点当年RO的感觉。而且当你打完第一章,拿到全成就后以为这游戏就这么结束了,谁知道大惊喜在后面,真正的放置内容才开始,防守波次天赋树,防守波次打到1000层后,又有神殿刷神器,本来这游戏最大的缺点就是装备属性过于固定、随机性不足,防守神殿的词条系统弥补了一点点,但是还是随机性不够强,到了神器系统词条的随机性很大,完全弥补了这个劣势,甚至可以当成半个挂机暗黑刷子游戏玩,为啥是半个,因为没套装系统。 而且按更新计划图来说这还不是终局内容,很期待后面还能更新啥,满分,强推
很好的挂机游戏
不错,但是除了刺客没解锁,其他角色的觉醒职业立绘好难看,不如之前的立绘,虽然可以改回去,但我超威,熬夜期待了这么久的缇娜你给我做好了啊,原本飘逸伶俐的射手范没有了啊喂
难得的国产优质挂机游戏,有丰富的内容给你去后期刷,同时又不会很臃肿搞的整个页面全是东西
Совершенно неясно, почему описание на русском изобразили, а в игре нет, но пока простим (добавят, полагаю). Пока что полёт нормальный, ощущается как лоафинг таун, только с большим уклоном в "исследование" и покрас карты\книги. Нраицца (пол часа в игре). Если вы не в курсе, что такое оверлей игры, то в целом описание вполне правдивое.
