Our guide site offers deeper insight into building effective squads, optimizing idle growth, and navigating the random loot system. While the game provides a solid foundation, strategic tweaks can enhance enjoyment and efficiency without altering core mechanics.

01 / THE GUIDE

Class Balance Review

Compare the talent trees of Warriors and Tanks, noting where defensive bonuses overlap. Adjust your team to see if a pure tank lineup can match a mixed composition in survivability.

  • Check the offline progress timer regularly to see how much growth you earned while away.
  • Balance active play with idle time to ensure you have enough resources for upgrades.

02 / THE GUIDE

Idle Timing Test

Track offline progress over a 24-hour period, then compare the amount of growth achieved to a similar duration of active play. This highlights the idle system’s contribution.

  • Experiment with different class combinations to discover synergistic effects.
  • Focus on filling talent trees early to unlock class-specific advantages.

03 / THE GUIDE

Skill Tome Fusion

Gather multiple skill tomes for a single hero, then experiment by swapping them in the skill tree. Observe how different combinations affect combat outcomes against the same enemy type.

  • Collect a variety of skill tomes to keep your options open for future builds.
  • Regularly review talent allocations to adapt to new content or enemies.

04 / THE GUIDE

Synergy Exploration

Create several four-hero teams focusing on a single role (e.g., all Assassins) and record the unique synergistic effects triggered. Contrast these with mixed-role teams to gauge versatility.

  • Try forming homogeneous teams to test specific synergy bonuses.
  • Swap heroes after major updates to see if new synergies emerge.

05 / THE GUIDE

Random Loot Mapping

Log loot drops from various battlefields and dungeons over several sessions. Identify patterns in rarity and item type, helping you target specific locations for desired gear.

  • Participate in varied battle types to increase the diversity of loot you receive.
  • Keep an eye on rare loot drops after boss encounters for valuable upgrades.
