Embark on an Epic Adventure in Idle RPG


Collect monsters and combine them to become the epic heroes of the frontier in this idle RPG. Long ago, the Old Gods, heroes of a forgotten era, united their tribes to purge The Darkness from the monster world. Now, The Darkness has returned, and the Old Gods are blind to the threat. It's up to you to collect monsters from every tribe and combine them to save the world from endless darkness in this idle RPG.



Monsters as Heroes


Build a team of heroes by collecting monsters. There are over 150 monsters to discover, with even more to come. Merge monsters to double their power and prevail in monster battles.



Merge Monsters to Level Up


Unlock monster fusion to merge monsters into legendary heroes. Combine monsters to unlock extra slots for skilling.



Skilling Your Monsters


Each monster has up to 6 skill slots, depending on their rarity. Epic and Legendary monsters possess more skill slots. Mastering skilling is just as crucial as leveling up your monsters.



Idle Clicker Game Mechanics


With generous offline progress and earnings, your monster heroes never sleep. You can even capture monsters while offline! Sit back and watch the idle action unfold as your legendary heroes clash in this auto RPG. Prestige to the next level when you're ready for more epic monster collecting.



An Endless Frontier to Explore


The idle adventure never ends. With incremental mechanics and no damage, distance, or level caps, this endless auto idle RPG is not your average monster collecting game. Monsters will adventure through the frontier, winning battles to collect monsters and gold to bring back to your base. Discover new areas and strategies!



Auto RPG with Potions and Spells


Adventures always start at your home base. Command your monster team to explore the frontier, then sit back while auto RPG mechanics take charge of the monster battles. Utilize potions and spells to aid your monster team in battle.



Home Base Building


Level up your home base to unlock potions and spells. New options for skilling and leveling up become available as you reach new distances and purchase buildings. Explore monster fusion in the Secret Lab and participate in monster sacrifice at the Altar for permanent boosts.



Defeat Epic Bosses and Climb the Tower


After you prestige, your monster team can enter the Tower to battle legendary heroes and epic monsters. Defeat every monster team in battle to climb the tower, collecting gems and monster rewards for every victory.
