About This Demo

Forge Your Destiny in a Rich High-Fantasy Idle RPG

Dive into a story-rich fantasy world where depth of strategy meets idle progression. In this Idle RPG with gripping rogue-lite elements, you will command a growing roster of heroes, conquer shifting battlefields, and craft the ultimate growth strategy to defeat darkness.

Note: In the Demo, you get the complete story for World 1 and then get to play in an endless mode up to floor 150! While characters, relics, and floors do not carry over from this demo to the full game, any exclusive badges, skins, or other quick unlocks will persist!

Key Features

Special Abilities: Unlock special abilities to help you units fight or bring in hordes of riches!

Unlock 4 (out of 19+ in full game) Playable Characters: Discover, unlock, and recruit a diverse cast of heroes, each bringing distinct abilities and interesting lineups with many, many more to come!

A vast world: Journey through deserts, forests, caves, and forgotten dungeons. (Demo goes through 2 zones)

Hand-Crafted Foes: Test your strategic limits against over 35+ unique hand-crafted pixel art enemies, all with their own strengths and weaknesses, with many more on the way.

Solo & Social Events: Tackle exclusive solo special events for rare rewards, or team up in cooperative Group Events (Coming Soon!) to conquer challenges alongside your friends.

Manage Flexible Progression Paths

Tailor your units to match your specific play style and adapt to any challenge using five deep progression systems:

  • Relic: Discover and activate 10 (out of 40+ in full game) unique relics that inject powerful passive enhancements into your team.

  • Leveling: Push to higher floors to find new enemies, secrets, and push your units to new leveles (up to floor 150 in Demo).

  • Merging: (not available in Demo) Combine units for massive jumps in their power potential.

  • Enhancements: By Iseking, you can invest in individual stats to balance and control unit growth rates.

  • Equipment: Unlock upgrades using gold in a massive equipment tree.

Unlimited Flexibility:

By mixing and matching relics, customized gear from the blacksmith, and divine church blessings, you have total control over your growth strategy. Build for riches, speed, or just purely based on what your favorite character's hair color! With the flexibility of the builds, there is no right answer except the path you choose.
