More about this game
You are the architect of a dungeon under siege by warriors, mages, and healers. Your goal is to protect the glowing Heart from being breached by 3 heroes. During the build phase, spend your starting 21 Coins to deploy traps and monsters on the grid. Heroes will dynamically change their route to find the shortest path. Every 10th wave brings a Boss Expedition, while every 5th wave triggers a Cursed Event. The run ends if 3 heroes escape.
Tips
- Overlap your trap ranges with monster engagement zones. A Lava Trap slows heroes by 75%, keeping them in melee range longer.
- Boss Expeditions grant 15 emergency preparation Coins immediately when they appear. Save space on your grid to capitalize on this bonus.
- Slimes split into smaller tanks when defeated. Place them near chokepoints to stall large groups of heroes like Paladins and Clerics.
Questions
How do I unlock new monsters?
Five elite monsters unlock automatically at levels 15, 30, 45, 60, and 75. You can also spend Monster Gems in the Shop to unlock base units.
Why did my placement get refunded?
You must always leave a valid path to the Heart. If a placement completely blocks the heroes' route, the game refunds your Coins.
What happens during a Cursed Event?
Every 5th wave triggers a curse, such as Fog of War, which hides the dungeon and alters hero behavior for that specific raid.
