Top 5 Strategies for Idle Heroes
- Focus on One E5/E3 Hero First: Do not spread your resources across multiple heroes; concentrate all your EXP, gear, and gold into getting one main carry hero to E3 (Elite 3) or E5 (Elite 5) first. This single powerful hero allows you to clear high-level Campaign and Tower content, accelerating your resource income.
- Hoard All Major Currencies: Save your Heroic Scrolls, Prophet Orbs, and Cores of Transcendence for the major summoning events (Anniversary, CNY, Christmas) that offer immense rewards and guarantee specific meta heroes. Spending them impulsively outside these events drastically slows your progress.
- Prioritize the Best Transcendent Heroes (Trans): Once you can unlock Transcendent Heroes, prioritize building the current meta leaders like Void Campaign carries (often FQV or SFX) as they are required to progress through the highest-tier content. These heroes are the foundation for late-game success.
- Maximize Private Server/Offline Income: Ensure your highest-level heroes are placed in the Celestial Island and your team is optimized for the highest clear possible in the Campaign, as these modes determine the quality and quantity of your essential Idle offline rewards. Collect your Idle rewards multiple times a day.
- Be Active in Guild and Arena: Participate in the Brave Trial, Tower of Oblivion, and Guild Bosses daily, even if you lose, because they offer critical currencies and materials needed for long-term power-up progression. The rewards from these modes are non-negotiable for ascension.
